Heating medium side
F1145 has a heating medium pump that can be automat-
ically controlled. For manual operation: deactivate "auto"
in menu 5.1.11 and then set the speed according to the
diagrams below.
The flow must have a suitable temperature difference
for the operating case (heating operation: 5 - 10 °C, hot
water generation: 5 - 10 °C, pool heating: approx. 15 °C)
between controlling supply temperature sensor and re-
turn line sensor. Check these temperatures in menu 3.1
“service info” and adjust the heating medium pump
(GP1) speed until the temperature difference is attained.
A high difference indicates a low heating medium supply
and a low difference indicates a high heating medium
supply.
Read off what speed the heating medium pump should
have during manual operation from the diagrams below.

Readjusting, venting, heat medium side
Air is initially released from the hot water and venting
may be necessary. If gurgling sounds can be heard from
the heat pump or climate system, the entire system
requires additional venting. Check the pressure in the
pressure expansion vessel (CM1) with the pressure
gauge (BP5). If the pressure drops, the system should
be replenished.
