4 The green power lamp of the control box is ON when the DIRECTION FOR USE( 1 ) POWER: On a valve control boxThe green power lamp of the control box is ON when themain power switch of a valve control box is “ON” afterinstallation.The present temperature is displayed on a window of themaster thermostat and a symbol < - ? - > is blinked onall slave thermostats installed in each zone.: On a master thermostatPress the power button of the master thermostat. A greenlamp of the master thermostat is ON.The present temperature (left side) , the previously set pointtemperature (right side), zone No. 1 and the heating/coolingstate are displayed on a window.: On a slave thermostat① A symbol <- ? -> is displayed on a window once.② An user shall grant a zone number to each slave thermostat bydialing a knob in each slave zone, otherwise POWER will not be ON.③ An user can start to manipulate the functions when power is ON.☞All electric power of the slave thermostats is Off when the powersupply of the master thermostat is Off at the closing time in theevening. In the next morning a user has to press the POWERbutton of the slave thermostat in each zone again so that theslave thermostat can communicate with the master thermostat.( 2 ). How to set the desired temperatureThe temperature can be set with master thermostat as below.To change the setting of zone no.2 for example the zone no.2must be called first.① When zone no.2 (for example) is displayed on a windowof a master thermostat the present and previously settemperatures of zone no.2 are also indicated on either sideof the window simultaneously.② To change the previously set temperature value of this zoneno.2 dial a knob of the master thermostat to reach the desireddigits to be set as a new temperature value.③ Then, the new temperature value is displayed on a masterthermostat and it blinks 3 times on the salve thermostat ofthe zone No.2.4
5 ④ : The new temperature value disappears soon after blinking and instead the present temperature will show up again on a windowof the slave thermostat as usual. It means that a slave, a masterthermostat and a valve control box have memorized the newlyset temperature value and the setting has been completed forall 3 devices finally. (Temperature can be set by 0.5℃unit)NOTE : If a user spends 10 seconds without any setting for the calledzone the number of the called zone will disappear on a windowof a master thermostat. In this case an user can call the roomagain by pressing the zone button again.NOTE : An user can check the set temperature whenever he wants bydialing a knob of a slave thermostat a little to the right and left side.NOTE : On a master thermostat the set temperature value of a slavethermostat in each room is always shown so that an user cancheck it anytime.( 3 ). TIMER FUNCTIONThe time setting can be performed on a master thermostat only.This function is to operate the heating/cooling system forcibly fora few minutes within an hour unit regardless the set temperature.① The TIMER symbol MINUTE is displayed on a window whenpressing the TIMER button.② A user can set the desired heating/cooling time by dialing a knob. Theheating/cooling time is indicated by a minute unit.Example : MINUTEThe heat/cool system is ON for 10 minutes and Off for 50 minutes.③ This function is terminated when pressing the TIMER button again.Then, the timer symbol MINUTE is disappeared on a window.( 4 ). ZONE SELECTIONThis selection can be performed on a master thermostat only.An user can select a room of which he desires to check and control the statewith a master thermostat① The desired room is selected in sequence No.1~5 when the room buttonis pressed each time.② The zone No.1 is a number of the master thermostat’s own. This figureNo.1 is indicated first in beginning on a window.( 5 ). RESERVATION FUNCTIONThis reservation can be performed on a master thermostat only.An user can reserve the operation time if he wants to operate the heat/coolsystem at the desired time.① Press the zone button to call a zone to be reserved.
6 ② Press the fan speed( )and OUTGO buttons( ) over 1.5 seconds at the same time. Then.<The set temperature 00℃> is disappeared ona window.③ The desired time is indicated first as a figure 12 and a reservation symbolblinks on the window.④Dial a knob to the left and right side to reach the desired digits and stopdialing ( Variable hours 1~24).The reservation symbol( )blinks. While this symbol is blinking pressthe reservation button( ) again. The set temperature and a reservationsymbol are displayed on the window. Now, the reservation is completed.The reservation function is terminated when pressing the fan speedand the outgo buttons at the same time.⑤NOTE : If an user spends 10 seconds without any setting forthe called zone the number of the called zone willdisappear on a window of the master thermostat. Inthis case a user can call the zone number by pressingthe zone button again.NOTE : To cancel the reservation press the reservation buttonagain. Then “reservation” symbol disappears. Itmeans that the reservation function has been terminated.Example 1 :If an user reserves the operation time as “2” at 10 amand sets the zone temperature at 25 ℃ when goingout the system will stay ” un-operated” until 12 o’clockand come into an operation to reach the set temperature25 ℃ from 12 o’clock.Example 2 :If an user reserves the operation time as “2” at 7 pm and sets the zone temperature for 22 ℃ when going out the system will stay” un-operated” until 9 o’clock pm22 ℃ from 9 o’clock pm.NOTE : The reservation function can not be performed on the slavethermostat itself.
7 ( 6 ). OUTGO MODEThe heating/cooling system starts to work automatically at this mode when theroom temperature becomes below 15℃ under the heating control and above29℃ under the cooling control. This OUTGO function protects the waterdistributing pipe from being frozen to burst by operating the heating systemautomatically when the room temperature becomes below 15℃.① The set temperature is disappeared and either15℃ in case of the heating or29℃ in case of the cooling and the OUTGO symbol( ) are displayed atthe same time on a window of the master thermostat when the OUTGO buttonis pressed. The displayed OUTGO symbol means that the OUTGO mode hasbeen set completely.All OUTGO lamps (red) of the slave thermostats are ON because all slavethermostats in the slave zones become under the control of the OUTGO functionof the master thermostat at the same time when this setting is done on a masterthermostat. This OUTGO button can also be pressed on a slave thermostat ofeach zone independently for user’s convenience.② The OUTGO function is terminated when the OUTGO button is pressed again.The set temperature is re-displayed and the OUTGO symbol( )is disappearedon a window when the OUTGO function is terminated.( 7 ). INDICATION OF HEAT/COOL OPERATIONThe heat/cooling system starts to work when the difference between the currenttemperature and the set temperature becomes 1℃.① The Heat/Cool indicating lamps (Red) on the right upside of a master thermostatand a slave thermostat of the called zone when the Heat/Cooling system comesinto the operation.② And the called zone No. and a symbol( or ) are displayed on a windowof a master thermostat.☼１2345☼
