Heating medium side
F1245 has a heating medium pump that can be automat-
ically controlled. For manual operation: deactivate "auto"
Tillgängligt tryck, kPa in menu 5.1.11 and then set the speed according to the
Eleffekt, W diagrams below.

The flow must have a suitable temperature difference
for the operating case (heating operation: 5 - 10 °C, hot
70
water generation: 5 - 10 °C, pool heating: approx. 15 °C)
60
between controlling supply temperature sensor and re-
50 turn line sensor. Check these temperatures in menu 3.1
"service info" and adjust the heating medium pump
40
(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.

Readjusting, venting, heat medium side
Air is initially released from the hot water and venting
0,35 0,40 0,45
may be necessary. If gurgling sounds can be heard from
Flöde l/s
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.
