10 Power Stealing Assist Extends Battery Life Not available on the Easy Reader 1F95EZ-0671Power Stealing Assist extends battery life significantly by drawing “stealing” small amounts of voltage from the heat (W) or cool (Y) circuit. Power Stealing Switches on the back of the thermostat should be left in the “ON" position for most systems.On a small number of heating or cooling systems with high impedance electronic modules you may observe one of the following conditions:The furnace , draft inducer or fan run or continue running when the thermostat is not calling for operation. Switch the “W” dip switch to OFF.If the condition continues to occur switch the “Y” dip switch to OFF to disable Power Stealing Assist completely and operate the thermostat on batteries only.If the Power Stealing Assist method is not compatible with your system both switches can be turned off and the thermostat will operate normally.

What do we mean by a “UNIVERSAL THERMOSTAT?” Universal means ONE thermostat that can be installed on almost any system…This thermostat is Four Thermostats in one…Single Stage, Multi-Stage Gas or an Electric Furnace. Heat Pump Single Stage or Two Stage Compressor with up to two stages back-up Electric heat or Gas with a built in Dual Fuel option that does not require an outdoor sensor or fossil fuel kit.You can customize the thermostat to be a Heat only, Cool only, or a Heat/Cool operation. It will work on almost any fossil fuel, heat pump, hydronic systems, and millivolt systems. When we say Universal we really mean it!Simply configure to match your system. Note the SS1, MS2, HP1, HP2 in the boxed column… You can configure the thermostat for up to 4 stages of heating and 2 stages of cooling.

To see it for yourself just enable the batteries on the sub base and let the thermostat power up in the factory default non-programmable mode.Looking in the upper left corner of the slide and moving around the thermostat:Battery Status, this indicates the power level in the batteries. Over time the batteries will lose power and the hash marks will slowly disappear. When there are only two of the four hash marks appearing it is time to replace the batteries with 2 fresh “AA” batteries.Heat Pump/Auxiliary Heat Indicator, if configured for a heat pump the word AUX will appear. If Aux becomes bold this indicates the auxiliary (Emergency) stage is selected.Heat Button, when bold you are in the heat mode, note, that it is one button, one operation—how easy is that?A/C Button, when bold you are in the air conditioning modeOff Button, when bold the system is offFan Button, when bold indicates the Fan has been turned on manually to run continuously. This button is also used to validate “RUN” changes in the configuration menu.Menu Button, this is the button you press to configure the thermostat—note for the installer configuration the “Menu” button must be held down for 5 seconds. This prevents accidentally entering the configuration menu in day to day operationTemperature Up and Down, to be warmer press the red up button, to get cooler press the blue down button. These buttons are also used to navigate through your options in the configuration menu.Desired Temperature, this is the temperature you would like the home to be at in heating or coolingActual Room Temperature, this is the actual temperature in the home. Note how big the temperature display is.
15 6” Entering System Configuration 2. Press and hold the MENU button for five seconds1. System must be in HEAT or A/C ModeTo begin configuring this Easy Reader for the right application enter the configuration menu by pressing the Heat or A/C button. Next press and hold the menu button for 5 seconds. You can now configure the thermostat for the application. Your choices are SS, MS, (single stage or multi-stage fossil fuel) or HP1, HP2 (single stage or multi-stage heat pump).The bulk of Technical Service Help calls on Universal Thermostats occur because someone forgot to configure the thermostat for the correct system application.Before the introduction of Universal thermostats - showing up on a Heat Pump job with a Single Stage fossil fuel thermostat meant a trip back to the supply House. Or…you had to carry 4 or 5 thermostats on the truck in SS/MS/HP and programmable or non-programmable flavors. ….With all those stats….Where are you supposed to put your tools???Now with the Universal Easy Reader thermostat you have one thermostat for all these applications.Most technical service calls are the result of improper system configuration

Choose System2. Select Fan FunctionItems 1 and 2 are what make the thermostat and system work together…Most other menu items except dual fuel are a matter of personal preference…Just keep in mind, the first step is to tell the thermostat what the primary heating source is; fossil fuel or a heat pump?The second step tells the thermostat if the equipment or the thermostat control the fan operation. Fossil fuel systems have a fan control built into the equipment to turn on the fan on a call for heating. Heat Pumps and Electric furnaces require the thermostat to turn the fan on during a call for heating.Once you configure for the system just press “RUN” and you are ready to operate the system. You will see the word “RUN” right above the Fan button at this point. Any of the other configuration options are a matter of choice.After steps 1 and 2,Press RUN to get the system running quickly

Basically you are telling the thermostat if the equipment operates the fan or the thermostat needs to operate the fan.Gas position = Furnace energizes fan during the heat cycle.Elect position = Thermostat energizes fan on call for heat.Note: Electric is used for Electric Furnaces and Heat Pumps that don’t have a fan control and require the thermostat to turn on the blower on call for heat.Press the temperature up or down button to scroll through the selections. Once the correct choice is made hit the button below where the screen says Run (this is the same button to turn on the fan in normal operation.)That’s it! You are now ready to run the system. You can configure for many other options to customize for the system by entering the configuration menu and making your choices (see next slide)Press Run to complete initial configuration
19 Configuration Punch List Record settings of key items for Homeowner ReferenceOn the back of the homeowners manual there is a punch list that lets the installer choose the various options they wish to configure the system for. It is good practice to check the appropriate boxes after full configuration is done and leave with the homeowner for future reference if needed.

While we won’t go through all the options we will highlight some of the most used options.EMR in step 3 is an acronym for “Energy Management Recovery”. What it looks at is the room temperature during a setback period and also looks forward to the next program time and temp. The thermostat sees the number of degrees it needs to make up and starts early based on that number.Tech Stuff: For non-heat pump systems it allows approximately 5 minutes for each degree it needs to make up.For heat pump systems it allows approximately 15 minutes for each degree it needs to make up.Heat Pumps produce a lower temperature heat than fossil fuels systems so they take longer to recover to set point temperature after a set back period.. The heat pump is started early and locks out the Aux heat until about the last 30 minutes of the recovery period. Neat feature – it allows economical setback and recovery with a heat pump system – conventional wisdom says don’t setback a heat pump because the Aux. will eat up your savings.Guess what? You can setback a pump…and recover….economically.

Heat. Dual Fuel turns off the pump(s) when Aux comes on so the system does not trip on excessive pressure. Eliminates the need for a plenum mounted fossil fuel kit. 1-9 sets it up for Dual Fuel. Higher number pulls auxiliary in a little sooner. Lower number delays auxiliary slightly. We suggest 5 to start with and adjust as desired. An easy way to remember where to set the values ---up for comfort (tight temp control) and down for energy savings. Remember, if you set the value to zero you disable this option.Step 22, Compressor Delay allows the Aux. Heat and the heat pump to run at the same time…up to 99 seconds. This gives the Aux. a chance to heat up before the pump turns off. This will stop you getting a “slug” of cold air when staging.
25 Two Options for Staging Smart Logic (Computed Staging)Easy Viewer tracks system performance and calculates optimum time to bring on additional stages (0 to 30 minutes) .Note: Depending on system performance the time for staging will vary depending on the algorithm software. The calculation is not purely time nor temperature based. Staging times are going to vary from day to day.Gives homeowner the choice of cost savings or comfortFast Second Stage (Optional feature)Brings additional heat stage when temperature is manually raised 3°FGives homeowner optimal comfortFor initial startup, configure for Fast Second Stage to save time evaluating system operationsFast second stage recognizes that if you standing in front of the thermostat adjusting the temperature a few degrees or more higher….. you are pretty serious about getting a quick warm up. This option allows the staging to occur in real time instead of going through the algorithm delay.Computed staging is how the thermostat handles staging in normal operation . Computed staging brings second stage on…based on the first stage performance. When first stage has been doing a good job but the temperature drops a little the computer pushes second stage out a little…(longer delay) This gives first stage a fair chance to do the job. If first stage performance continues slipping it pulls second stage in faster… and faster.. This automatically adjusts and optimizes comfort (making set point) and economy (using lowest stage practical).
26 Staging Logic versus Outside Sensor Dual Fuel Applications (Optional)Easy Viewer uses its Smart Logic to manage coordination of heat pump and furnace operation. When the Dual Fuel stages are called for the Easy Viewer will shut down the compressors on the heat pump.Without the use of an outdoor sensor and a fossil fuel kitIf you normally use an outdoor sensor and a fossil fuel kit for dual fuel applications the Easy Reader is a great solution!Think of the time and money you will save on the next installation.Smart Logic is a unique feature in the Easy Reader. It is how the thermostat handles staging in normal operation . Computed staging brings second stage on…based on the first stage performance. When first stage has been doing a good job but the temperature drops a little the computer pushes second stage out a little…(longer delay) This gives first stage a fair chance to do the job. If first stage performance continues slipping it pulls second stage in faster… and faster.. This automatically adjusts and optimizes comfort (making set point) and economy (using lowest stage practical).To learn more about the staging logic click on the link below to go to the White-Rodgers Learning Channel.Dual Fuel Applications do not require an outdoor sensor or fossil fuel kit to operate. With our unique Staging Logic algorithm the thermostat calculates the system performance and stages as needed. On dual fuel applications when the fossil fuel stages are required the thermostat will turn off the heat pump compressor and energize the fossil fuel furnace---without having to install an outdoor sensor and fossil fuel kit. This results in both time savings, and material installation costs—and it is based on performance of the system which is a more accurate determinate when staging a system.
27 6” Dual Fuel Settings—No Sensor Req. The Dual Fuel Logic allows control of a heat pump with fossil fuel backup heat without the use of a fossil fuel kit. When fossil fuel is called for the thermostat will turn off the compressor and switch to gas heat automatically using the Dual Fuel Logic algorithm.Access the Configuration Menu Step 20The dual fuel setting options range is 0 to 90 is default Off allowing electric heat to be usedSettings of 1 to 9 is a value used in the software algorithm.Up for ComfortIncreasing the value up to the max of 9 will result smaller staging separationDown for Energy SavingsDecreasing the value to a minimum of 1 will result in larger separationSelect Compressor Delay – When dF is enabled, the shut down of the compressor(s) is delayed for a time period after the auxiliary stage is energized. This delay, Cd, is factory set at 60, but can be set in the range of 0 to 99 seconds by using the PLUS or MINUS touchpad's .

When AUX is bold the stage is engaged.
34 Troubleshooting Tips“My thermostat brings on 2nd stage too fast! I don’t want to use the expensive back-up heat”Solution: Homeowner needs to lower temperature settings to avoid use of that stage of heat.“My thermostat won’t bring on 2nd stage, even when I raise the temperature a few degrees, for 15 or 20 minutes sometimes”Solution: Turn on the fast 2nd stage.“I’ve been timing the thermostat to see when it brings on the back-up heat and writing it down. This thing is possessed”Solution: Put down the stop watch. It is a complicated calculation, not solely time or temperature based.Computed staging does bring on second stage faster….when first stage is not keeping up. This is due to the algorithm calculating the equipment cannot keep up with the set point temperature. Remember you are trying to maintain comfort and have energy savings with the Easy Reader. If the homeowner feels 2nd stage of back-up heat is coming on too quick they need to reduce the set point temperature. Also with the Smart Logic… it brings stages on slower….when first stage is keeping up so you get the energy savings. Remember, the staging logic is all about performance. If the system is keeping up with the set point the system will operate at its most efficient level to deliver comfort and economy.…for homeowners that are constantly checking the system operation….You can not out-calculate the computed algorithm in the Easy Reader. The algorithm is not time nor temperature based. Put down the stopwatch and let the thermostat do its job! Within a hour of installation (or a little less…) it has sampled the room temperature constantly, knows your current…and future set points, and has developed a performance model of your system….that it updates…constantly. If the homeowner wants to control more tightly when second stage comes on when they change the temperature the installer needs to engage the “Fast Second Stage” option for the homeowner. That way when the temperature is manually raised 3° F or more the second stage will come on immediately.Once EZ is acclimated and controlling room temp…..you really need to relax. It does the hard stuff like balancing comfort and economy…it is designed to be a set it and forget it thermostat.
35 Some Things To Remember Most common mistake is not choosing correct configuration for the applicationSS, MS, HP1, HP2Easy Reader does not have Staging IndicatorsDesigned intentionally for simplicity of operationEasy Reader ships as a Non-ProgrammableAsk the homeowner if they want programmableDual Fuel can be used on both HP1 and HP2Some think it is only for HP2Technical Trivia SectionQuick slide with observations from out Technical Service Team…. And the questions they get most often from the field.1. Making a menu selection. If you choose the wrong application in step one the system will not work correctly. Ensure you configure Step 1 (Application) and Step 2 (Fan Operation) and the system is ready to operate.2. You would not believe how many people call us when their thermostat reads Stage 2… Even if it is 5 degrees outside… We took the staging indicator off because of these calls from the field. The Easy Reader is designed to be the most homeowner friendly thermostat on the market. We did our homework on this design to make it a “set it and forget it thermostat”.3. Out of the box it is a non-programmable thermostat. If the homeowner wants to have it programmed first fill out the programming worksheet in the homeowners manual (see next slide for example). Then configure and program the thermostat. Leave the programming sheet with the homeowner. Our Technical Service team has never not been able to walk a homeowner through the programming steps if this sheet is filled out.4. Dual fuel is available on all HP settings….Don’t know how the rumor got started that the dual fuel option won’t work on single stage heat pumps, it will—Dual Fuel works on all heat pump options.
