# Code
[9.6.3] [5-04] Offset BSH setpoint: Set point
correction for domestic hot water
temperature: set point correction for the
desired domestic hot water
temperature, to be applied at low
outdoor temperature when space
heating priority is enabled. The
corrected (higher) set point will make
sure that the total heat capacity of the
water in the tank remains
approximately unchanged, by
compensating for the colder bottom
water layer of the tank (because the
heat exchanger coil is not operational)
with a warmer top layer.
Range: 0°C~20°C

Water pipe freeze prevention
Only relevant for installations with water piping outdoors. This
function tries to protect outdoor water piping from freezing.
# Code
[9.7] [4-04]
Drain prevention
Only applicable when the bivalent function ([C‑02]) is activated. This
function prevents the opening of the freeze protection valves in the
water piping to the outdoor unit when the auxiliary boiler is running at
negative outdoor temperatures.
Power saving function
Power saving function
T
A
Defines whether the outdoor unit power supply can be interrupted
(internally by indoor unit control) during stand-still conditions (no
space heating/cooling nor domestic hot water demand). The final
decision to allow power interruption of the outdoor unit during
standstill depends on the ambient temperature, compressor
conditions and minimum internal timers.
To enable the power saving function setting, [E‑08] needs to be
enabled on the user interface.
# Code
[9.F] [E‑08]
Benefit kWh power supply
INFORMATION
The preferential kWh rate power supply contact is
connected to the same terminals (X5M/9+10) as the safety
thermostat. It is only possible for the system to have
EITHER preferential kWh rate power supply OR a safety
thermostat.
8 Configuration
Description
Maximum running timer 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 Control=Room thermostat: 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 Control≠Room thermostat: This
preset value is always taken into
account.
Range: 5~95 minutes
Remark: It is NOT allowed to set [8‑01]
to a value below 10 minutes.
Additional timer: Additional running time
for the maximum running time depending
on the outdoor temperature [4-02] or
[F-01].
Range: 0~95 minutes
