SECTION 3: OPERATION
•
The Heat Pump has an internal thermostat located in the return water pipe which maintains
storage tank water temperature at the nominated set point. The normal operating range
for entering water is between 55
°
C and 57
°
C.
•
As water usage occurs, mains water will enter the storage tank, lowering the overall stored
water temperature, which in turn, activates the Heat Pump. The Heat Pump will run until
the water temperature (at the sensing point) reaches set point.
