4. Usage
3. DHW Settings
3.01
Set temperature for sanitary hot water.
3.02 DHW Restart ∆T Setting
Heat pump unit will start working for sanitary hot water again, after temperature drops below Tset-3.02
here.
3.03 Shifting Priority
Turn ON/OFF this function.
Air to water heat pump is an equipment that absorbs heat from surrounding air, and transfers it to water.
The lower the ambient temperature is, the less heat the unit absorbs. This makes the unit heating
capacity and efficiency drop when ambient temperature drops. The unit takes longer time to heat up the
sanitary hot water. However, the lower the ambient temperature is, the more heat the house demands.
If the unit does not provide enough heat while it is working for hot water, the temperature inside the
house may drop too much, and people in it feel uncomfortable. So parameters 3.03~3.08 try to divide
the working time for sanitary hot water into several cycles, after ambient temperature drops below a
set value. When this function is ON, AH (Auxiliary Heater) or HWTBH (Hot Water Tank Back-up
Heater) or both, depending on their priority, will work individually or together to enhance heat pump’s
capacity in sanitary hot water mode to heat up the water as soon as possible.
3.04 Shifting Priority Starting Temp.
Set an ambient temperature below which this function starts to work. When shifting priority function
is activated, heat pump will try to find a balance between DHW and Heating operation after ambient
temperature drops below this temperature.
3.05 Sanitary Water Min. Working Hours
Set the minimum working period for sanitary hot water mode.
3.06 Heating Max. Working Hours
Set the maximum working period for heating mode, after unit enters into heating mode.
3.07 Allowable Temp Drift in Heating
Set allowable temperature drift in heating mode.
3.08 DHW Backup Heater for Shifting Priority
Working mode of HWTBH (Hot Water Tank Back-up Heater) in this function. If this parameter is set
ON, when heat pump is switching to house heating, HWTBH will keep on working to help the uni heat
up hot water as soon as possible.
