Press OK to confirm and turn to next setting. C. Then, the icon from 0:00 to 1:00 and the preset temperature state icon (i.e. the icon on the left siude of the temperature digit) will start to blink. Press or to select the temperature state and press OK to confirm. The temperature state display in the following one hour will be fully changed to the selected temperature state ( For heating control, the comfortable temperature is represented by double solid frame, the economic temperature is represented by single solid frame and one single empty frame, and the antifreeze temperature is represented by double empty frame. -11- For cooling control, the comfortable temperature is represented by double solid frame, the economic temperature is represented by single solid frame and one single empty frame, and the empty room temperature is represented by double empty frame). Meanwhile, it turns to setting of the temperature in next hour. D. Repeat the above steps until completing the setting of temperature state in 24 hours. Then, return to date selection. Under the program setting state for each hour, you may short press key to return the setting for last hour, and long press key to exit the temperature setting for remaining time and directly enter into date selection again. The temperature for unset part remains to be the default temperature or the preset temperature before. E. The date icon will start to blink again, entering into a new setting cycle for some day. F. End the program setting: You may long hold down OK key to exit the program setting and enter directly into user defined run mode. In the working state display area, the icon and will be displayed. Copy One-day Program After entering a day program you can copy this into another day to save time when creating a weekly program:For example, if you want to copy the program of Monday to Thursday, the methods are as follows: A. Select the program for Monday: On the state , press key or key The outer frame for Monday flashes to select Monday and press SET key for 3 seconds until the word C OPY appears on the screen B.

Switch between Three Setting Modes: You may press SET key to switch between three setting modes, i.e. date / time setting, temperature setting and auto program setting. 6. Switch from Setting Mode to Run Mode After completing the setting, you may long hold down OK to switch the thermostat to run state. If no operation of any key within 60 seconds under any setting state, the thermostat will automatically resume to the run mode before this setting. 7. Temporary Change of Temperature Both at mode and at and mode, you can temporarily change the temperature at a program period. For example: You have set the program already the comfort temperature is 20℃ between 9:00~18:00, but you want to lower the temperature to 18℃ at 10:00 then you set the temperature to 18℃ . This setting will not exist forever, it will remain until 18:00 when the program period is ended. At the program running mode, set the required temperature directly through key or key, the number representing the temperature will flash, and your adjusted temperature will be displayed. Without any adjustment in 5 seconds, The number representing the temperature will stop flashing and continuously to display the present room temperature. The thermostat will recover to automatic mode at the following program temperature changes. 8.External Temperature Probe (Optional) After connecting external temperature probe, please make corresponding setting in the engineering setting number 8. -13- 9. Code Match Setting (Only used for RF /MRF model) WH611 RF Model: Press the receiver key, so that the receiver indicator will blink. If the transmitter is energized, turn off the transmitter LCD and then hold down and keys simultaneously until the indicator stops blinking. In this case, the code matching is finished. ( Note: If no code matching signal is received during 1 minute when the indicator keeps blinking, this indicator will turn dark and the code matching will be stopped. Pressing the key again, the thermostat will again enter into code matching state). WH611 MRF Model: Press the receiver key, so that the indicator will blink in “ one st flash and one stop”. The thermostat will enter into the 1 channel code matching state. The code matching operation is same as that under WH611 RF model. After completing the code matching, press the key again to start the 2nd channel code matching, in which case the indicator will blink in “ two flashes after one stop ”. The thermostat then enters into code matching state. After completing the code matching, press the key again to start the 3rd channel code matching, in which case the indicator will blink in “three flashes after one stop”. The code matching is then started. Likewise, press the key for the fourth time to start the 4th channel code matching, in which case the indicator will blink in “four flashes and one stop”. 10. Fault Display: When the room temperature is lower than 0℃, the LCD will blink in 00.0℃. When the room temperature is higher than 0℃, the LCD will resume automatically to normal display. When the room temperature is higher than 45℃, the LCD will blink in 45.0℃. When the room temperature is lower than 45.0℃, the LCD will resume automatically to normal display. -14- Upon disconnection of the temperature sensor, the display will blink in E0.1, in which case you shall check and eliminate the fault. 11. Engineering Setting If long holding down Set key for 5 seconds under OFF state, the screen will display SET. The place where the time is displayed will show the setting number, while the place where the temperature is displayed will show the set parameters. Press or to change the parameter setting, and long hold down OK to change the setting number. You may hold down Set key for 5 seconds to exit the setting of engineering parameters. If no operation of any key within 60 seconds, it will save and exit, then return to Off state. -15- C F C 123 F SE T O UTDO O R C OP Y A 12 3 A S ET O UTD O OR 12 3456 7 C O PY 1 23 45 67 C F C 123 F SE T O UTDO O R C OP Y A 12 3 A S ET O UTD O OR 12 3456 7 C O PY 1 23 45 67 C F C 123 F SE T O UTDO O R C OP Y A 123 A SET O UTD O OR 12 3456 7 C O PY 12 34 56 7 C F C 123 F SE T O UTDO O R C OP Y A 123 A SET O UTD O OR 12 3456 7 12 34 56 7 -16- C O PY C F C 123 F SE T O UTDO OR C O PY A 12 3A S ET OU TD O OR 12 3456 7 C O PY 12 34 56 7 C 123 F SET OU TDOO R CO PY A C 123 A F S ET OU TDO OR CO PY 12 3456 7 12 34 56 7 C 123 F SET OU TDOO R CO PY A C 123 A F S ET OU TDO OR CO PY 12 3456 7 12 34 56 7 C 123 A F S ET OU TDO OR CO PY 12 3456 7 Keypad Keypad not activated (default) (When you set locking any key of the thermostat, Lock SET and Fan key the colon at the middle of time display will stop Lock all key except On/Off key flashing) C 123 F SET OU TDOO R CO PY A 12 34 56 7 C 123 A F S ET OU TDO OR CO PY C 123 F SET OU TDOO R CO PY A 12 3456 7 12 34 56 7 C 123 A F S ET OU TDO OR CO PY C 123 F SET OU TDOO R CO PY A 12 3456 7 12 34 56 7 C 123 F SET OU TDOO R CO PY C 123 A F S ET OU TDO OR CO PY A 12 3456 7 12 34 56 7 -17- Fault Repair Cautions on Installation and Use 1. To prevent the thermostat display from a high fluctuation, special treatment has been made to the program. Therefore, it is normal that the thermostat cannot immediately display the sudden change of temperature. 2. The thermostat installed in standard 86 box shall be placed 1.5m above the ground. 3. For the thermostat installed in standard 86 box or wireless thermostat with battery seat, take care not to install it to the wall corner, door / window side or behind the door or in such unheated area as exterior wall. Avoid hot / cold air duct, radiator, flue or thermal pipe. -18- 4. If the wireless thermostat with battery seat is placed at a position where the air ventilation is poor, the temperature displayed on the thermostat might be inconsisten to the indoor average temperature. 5. Only the professional technicians are permitted to open the transmitting and receiving box of the thermostat for installation. When installing the power supply, make sure that the power cable is well insulated. 6. To install the receiving box, please install the base plate firstly and then connect the power and signal wire correctly before installing the upper cover and fix it. The thermostat is unrepairable product. The user shall not open the internal circuit board. 7. Before installing the thermostat, make sure that the system is disconnected. The maximum voltage of the system shall meet the requirements specified in the Instruction Manual (Max. AC Voltage: 250V). Wring Illustration 1. Wiring Terminals 2.
