Disinfection
Applies only to installations with a domestic hot water tank.
The disinfection function disinfects the domestic hot water tank by
periodically heating the domestic hot water to a specific temperature.
N/A
[6-01]
The temperature difference determining
the heat pump OFF temperature.
#
Code
Description
N/A
[8-00]
Minimum running time for domestic hot
water operation. During this time, space
heating/cooling is NOT allowed, even
when the target domestic hot water
temperature has been reached.
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].
Q
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 heat pump OFF
temperature.
Q
When system layout
≠
Room
thermostat control: This preset value
is always taken into account.
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].
N/A
[8-03]
Booster heater delay timer.
Only for EKHW*
Start-up delay time for the booster heater
when domestic hot water mode is active.
Q
When domestic hot water mode is
NOT active, the delay time is
20 minutes.
Q
The delay time starts from booster
heater ON temperature.
Q
By adapting the booster heater
delay time versus the maximum
running time, you can find an
optimal balance between the energy
efficiency and the heat up time.
Q
If the booster heater delay time is
set too high, it might take a long time
before the domestic hot water
reaches its set temperature.
Q
The setting [8-03] is only meaningful
if setting [4-03]=1. Setting [4-
03]=0/2/3 limits the booster heater
automatically in relation to
heat pump operation time in
domestic water heating mode.
Q
Make sure that [8-03] is always in
relation with the maximum running
time [8-01].
N/A
[8-04]
Additional running time for the maximum
running time depending on the outdoor
temperature [4-02] or [F-01].

WARNING
Be aware that the domestic hot water temperature at the
hot water tap will be equal to the value selected in field
setting [2-03] after a disinfection operation.
When the high domestic hot water temperature can be a
potential risk for human injuries, a mixing valve (field
supply) shall be installed at the hot water outlet connection
of the domestic hot water tank. This mixing valve shall
secure that the hot water temperature at the hot water tap
never rise above a set maximum value. This maximum
allowable hot water temperature shall be selected
according to the applicable legislation.
CAUTION
Be sure that the disinfection function start time [A.4.4.3]
with defined duration [A.4.4.5] is NOT interrupted by
possible domestic hot water demand.
