supply water, on order to avoid frequent moving of compensating valve.
In Direct thermal mode, when the mid-water level is disconnected, the host will Open the water
valve, heat pump thermostat begins to work. If the thermostat switches pull in, the host would press
and the fan would work and the circulating water pump would shut down. The same for the
high-water absorption mode, thermostat stops working. At high water absorption time, when water
temperature is 5 lower than the setting temperature, it will enter the heating circulation and pumps
circulation, compressors and fans will run, the compensating water valve will shut down, and the
thermostat won’t work; when the low water level is disconnected, the pumps won’t supply water and
electric heating begins. At the low-water level absorption time, when the water temperature is lower
than the setting temperature limitation, it will take the priority for circle heating.
When the supply water valve is turned on, if the high-water level is disconnected and the tank
water temperature is lower than -3 (initial setting)then the tank would not compensate water. If the
tank water temperature is higher than setting value then it would compensate water and the
high-water level would last pull-in water 2 minutes before shut down the compensating water
valve( when there is a temperature control the supply of water).
If power up for the first time, it is necessary to circulate pumps after lower-water level absorbs,
then the compressor would run.
When the unit is running, the circulating water pump opens. When the unit stops, the circulating
pump will stop operation 30 seconds later.
Backwater Solenoid valve runs according to water temperature detection. When the return water
temperature is higher than the setting temperature, the solenoid valve will stop return water. When
the return water temperature is lower than setting temperature, then the valve will open to keep the
water supply pipe preserving hot water for a long time.
You can choose water moods of compulsory and time, when the water temperature is over 40 ,
press the "
WATER SUPPLY
" key, or it meets the time requirement and it will supply the water,
When it is supplying the water, pressing "
WATER SUPPLY
" key, or it meets the stop water supply
requirement, water supply will stop. When the water temperature is below 40 , it won’t supply
water.
