DHW time setting
Determine following time duration : operation time of DHW tank heating, stop time of DHW tank
heating, and delay time of DHW tank heater operating.
- Active time : This time duration defines how long time DHW tank heating can be continued.
- Stop time : This time duration defines how long time DHW tank heating can be stopped. It is
also regarded as time gap between DHW tank heating cycle.
- Boost heater delay time : This time duration defines how long time DHW tank heater will not be
turned on in DHW heating operation.
- Example of timing chart :

Time
The user activates the DHW function in the remote controller (DHW operation
7:30
starts by the heat pump cycle as the Thermo on condition is reached)
7:50
The booster heater is activated after the booster heater delay time(20 min)
The active time(25min) of DHW operation by the heat pump cycle ends and the
7:55
heat pump cycle is forced to be stopped (The booster heater is continues to
operate because the target temperature is not reached)
8:10
The booster heater operation ends as the target temperature is reached
DHW operation is not activated by the stop time(30 min) even though the water
8:20
temperature is dropped and DHW operation condition is reached.
When the active time condition is reached, DHW operation starts again by the
8:25
heat pump cycle
8:45
The booster heater is activated after the booster heater delay time(20 min)
