Hot water comfort
GENERAL
This function provides the opportunity to control addi-
tional heat in the tank, mixing valve and hot water circu-
lation.
ADDITIONAL HEAT IN TANK
If an immersion heater is installed in the tank, it can be
permitted to produce hot water at the same time as the
heat pump prioritises heating or cooling.
MIXING VALVE
A temperature sensor reads the temperature of the
outgoing hot water to the domestic hot water and ad-
justs the mixing valve from the water heater until the
set temperature has been reached.
HOT WATER CIRCULATION (HWC)
One pump can be controlled for the circulation of the
hot water during selectable periods.
PIPE CONNECTIONS
MIXING VALVE
The mixer valve (QZ1-FQ3) must be placed on the out-
going hot water line from the water heater according to
the outline diagram.

• Connect the incoming cold water via
the T-pipe to port B on the mixer
valve (closes at signal).
• Connect the mixed water to the do-
mestic hot water taps from the mix-
er valve to the common port AB (always open).
• Connect the outgoing hot water from the water heater
to the mixer valve to port A (opens on signal)
TEMPERATURE SENSOR
• Temperature sensor, outgoing hot water, (QZ1-BT70)
is installed as close to the mixing valve (QZ1-FQ3) as
possible.

Install the temperature sensors using cable ties, together
with the heat conducting paste and aluminium tape.
Then insulate with the enclosed insulation tape.
NOTE
To prevent interference, sensor cables to ex-
ternal connections must not be laid close to
high voltage cables.
