Limits on heat pump operation
In domestic hot water operation, following hysteresis values can be
set for the heat pump operation:

Timers for simultaneous request space and domestic hot water
operation
#
Code
Description
N/A
[8-00]
Do not change. (default: 1)
N/A
[8-01]
Maximum running time for domestic hot
water operation. Domestic hot water
heating stops even when the target
domestic hot water temperature is NOT
reached. The actual maximum running
time also depends on setting [8-04].
▪ When
system
layout
=
Room
thermostat control: This preset value is
only taken into account if there is a
request for space heating or cooling. If
there is NO request for space heating/
cooling, the tank is heated until the
setpoint has been reached.
▪ When
system
layout
≠
Room
thermostat control: This preset value is
always taken into account.
Range: 5~95 minutes (default: 30)
N/A
[8-02]
Anti-recycling time.
Minimum time between two cycles for
domestic hot water. The actual anti-
recycling time also depends on setting
[8-04].
Range: 0~10 hours (default: 3) (step: 0.5
hour) (only for EHBH/X).
Range: 0~10 hours (default: 0.5) (step:
0.5 hour) (only for EHVH/X).
Remark:
The minimum time is 1/2 hour
even when the selected value is 0.
