t_DHWHP_MAX is the maximum continuous working
period of the heat pump in DHW PRIORITY mode.
t_DHWHP_RESTRICT is the operation time for the space
heating/cooling operation.
Be aware that the domestic hot water temperature at the
hot water tap will be equal to the value selected in FOR
SERVICEMAN “T5S_DI” after a disinfection operation.
If this high domestic hot water temperature can
be a potential risk for human injuries, a mixing
valve (field supply) should be installed at the hot
water outlet connection of the domestic hot
water tank. This mixing valve will ensure that the
hot water temperature at the hot water tap never
rises above a set maximum value. This
maximum allowable hot water temperature shall
be selected according to local laws and regula-
tions.

If booster heater is not available(refer to 10.7
Field settings/Other heating source), please
disable DISINFECT, because the temperature of
water from heat pump is not high enough, and
the unit will stay in Disinfect mode for a long
time, which will effect space heating.
