1. The internal temperature controller should be installed away from the direct sunlight or

the position directly influenced by other cold and heat sources. The installation height
should be approximately 1.5 m off the floor.

2. Only the professionals can open the receiver box of the chronothermostat. to use 220V

power supply. The power supply wire must be guaranteed to be in the good insulation
during installation.

3. When installing the receiver box, the baseboard must be installed first and after

connecting the power supply and signal wire well, then put up the cover and fix it. The
chronothermostat manual cannot be used for repairing the product

and the user cannot

open the internal circuit board pers onally except for installation or disassembling the
batteries.

4. When you turn the switch to OFF position, you can set the state of the system controlled

PF under

the closed state, and the user can adjust

key or

key to change state. Then release OK

key.

(ON: Colse; OF:Open; PF : Antifreeze)

5. User can set the time when to turn on/off the system by the temperature difference

between opening and closing when reaching the setting temperature. Operation: press OK
key until display ADJUST under Manual mode, and set temperature difference by

or

key, Then release OK key. (Range: 0.5
