10 Power Stealing Assist Extends Battery Life (1F95 -1291 and 1280 Only)
Power 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.

11 12” Series Wiring for Conventional Systems - AC /Furnace (No Heat Pump)
#6 Terminal is for a power closed 3 wire zone valve Single Stage (SS) in Red Multi-Stage (MS) add Orange Shipped set up for Multi-Stage. The only difference between Multi-Stage and Single Stage are the additional 2nd stage calls for heat and cool. This configuration accommodates the majority of systems. Also has a #6 terminal (power closed) for 3-wire zone valves….very popular in certain areas with hydronic zone valves. Most thermostats won’t work a 3-wire zone system…comes standard on this one.… * Common connection requited for the 1F98EZ, diagnostic indicator, and outdoor sensor options. Optional on others. ** For two transformer systems remove the jumper

15 12” Application Specific versus Customization—Don’t Go Overboard!
MENU ITEM DISPLAY (DEFAULT) OPTIONS COMMENTS System Configuration (MS 2) SS1, MS2, HP1, HP2 Installer Set Electric Heat Fan (GAS) GAS, ELE 1. Choose System 2. Select Fan Function Items 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. Options are great but know the difference between application, options, and confusion to the homeowner.

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.

Hi (0) 1 to 5 Hi or LO °F/°C Selection (°F) °C Some other options you may wish to consider are: Step 10, Compressor Optimization. CO gives you a Fan On / Fan off delay in cooling. This assures the air is cold when the blower comes on and also scavenges cooling from the coil after the cycle ends by running the blower for an extra 20 seconds.

21 Optional Configuration Options
MENU ITEM DISPLAY (DEFAULT) OPTIONS COMMENTS Dual Fuel / Electric dF (0) 1 – 9 Compressor Delay Cd (60) 00 – 99 O/B Output Configuration On A/C (O) On Heat (B) Application Specific Set By Installer (HP1 or HP) Step 21, Dual fuel is for heat pumps with GAS or OIL Aux. 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.

This feature provides a method to program every day with the most popular time and temperature profile using one key press. For this feature to be available, the Auto schedule options (AS Cool or AS Heat) should be set on in the installer configuration. Select the desired “Comfort Temperature” in the setpoint. When the Auto Schedule touch key is pressed, it will start flashing indicating that it is now ready to insert the displayed temperature setpoint as the “Comfort Temperature” for the selected system mode currently in (Heat/Cool). A second press of the Auto Schedule touch key will complete the process. A 6 °F setback temperature will also be inserted for the night step. Once complete, the touch key display Auto Schedule will disappear disabling any further operation of Auto Schedule touch key. If desired it can be enabled again in the installer configuration menu.

31 12” Series Entering Fan Program
In the Set Schedule mode, the FAN key is used to select the fan operation during a program period. The default state of the Fan key is FAN Auto (fan runs during a call for cool but not on a call for heat). It can be changed to FAN Prog (fan runs during a program period). Each press of the FAN key will change the mode of the fan between Auto and Prog. In the Run mode, when a program period that has FAN Prog begins, the fan will turn on and stay on during the complete period. The display will show FAN On Prog. Pressing the FAN key will change FAN On Prog to On (fan running continuously) or Auto. To return to FAN On Prog, press Run Schedule.

32 12” Series Dual Fuel Settings
This feature is applicable only in heat pump modes and an outside remote sensor is installed, the thermostat can monitor the outside temperature. When the outside temperature falls below the selected setpoint temperature, dF, the thermostat will switch to gas heat and shut down the compressor. The eliminates the need for a fossil fuel kit. Use the or PLUS or MINUS touchpad's to select the desired setpoint temperature in the range of 5° F to 50° F Factory default is 5, which disables this feature. See Dual Fuel Temperature and Setpoint in Programming section. Select 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 .

33 12” Series Wired Remote Sensing
One remote temperature sensor can be installed indoor or outdoor and connected to the thermostat by a maximum cable length of 100 meters (300 ft). Three terminals, +, S & - are provided on the terminal block to connect to the White- Rodgers standard wired remote sensor. This sensor will be read by the thermostat only when 24 VAC is present. When used as indoor sensor, the readings can be weighted with the local sensor for specific program periods. User can enable or disable the remote sensor in the installer configuration mode and also the outdoor temperature can be selected to show on the display. In the installer configuration mode, momentarily press the PLUS or MINUS touchpad until display indicates Remote (at the top left of the LCD) and OFF (default – in clock digits). Pressing PLUS or MINUS touchpad will toggle the operation and display from Remote OFF to Remote On.
