Heating medium side
To set the correct flow in the climate system the correct
speed must be set for the heating medium pump in
the different operating conditions. This heat pump has
a heating medium pump that can automatically con-
trolled, but if a manual speed is desired it must be set
according to the following information and diagram.
For manual operation "auto" must be deactivated in
menu 5.1.11.
The flow must have a suitable temperature difference
for the operation (heating operation: 5 - 10 °C, hot
water regeneration: 8 - 10 °C, pool heating: approx.
15 °C) between flow temperature (BT2) and the return
temperature (BT3). Check these temperatures in menu
3.1 "service info" and adjust the heating medium pump
(GP1) speed until the temperature difference is
achieved. A high difference indicates a low heating
medium flow and a low difference indicates a high
heating medium flow.
Set the speed of the heating medium pump in menu
5.1.11, see page 52.
Read off what speed the heating medium pump should
have during manual operation from the diagrams be-
low.

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 will
require additional venting.
Readjusting, venting, collector side
Level vessel
2/3
LEK
Check the fluid level in the level vessel
(CM2). If the fluid level has dropped, top
up the system.
1.
Close the valve under the vessel.
2.
Disconnect the connection on top of
the vessel.
3.
Fill with brine until approx 2/3 of the
vessel is full.
4.
Reconnect the connector at the top of
the vessel.
5.
Open the valve under the vessel.
The pressure is raised by closing the valve on the incom-
ing main line when the brine pump (GP2) is running
and the level vessel (CM2) is open, so that liquid is
drawn down from the vessel.
Expansion vessel
LEK
If a pressure expansion vessel (CM3) is used
instead of a level vessel, the pressure level
is checked. If the pressure drops, the sys-
tem should be replenished.
Post adjusting the r oom temperat-
ure
If the required room temperature is not obtained, re-
adjustment may be necessary.
Cold weather conditions
႑
If the room temperature is too low, increase "heating
curve" in menu 1.9.1, one step.
႑
If the room temperature is too high, reduce "heating
curve" in menu 1.9.1, one step.
Warm weather conditions
႑
If the room temperature is too low, increase "temper-
ature" (heating curve offset) in menu 1.1, one step.
႑
If the room temperature is too high, reduce "temper-
ature" (heating curve offset) in menu 1.1, one step.

- Any high points in the climate system must be equipped with air vents 14
- F1255 consists of a heat pump water heater electrical module circulation pumps and a control system f1255 is connected to the brine and heating medium circuits 14
- F1255 is not equipped with external shut off valves these must be installed to facilitate any future servicing 14
- General 14
- In the heat pump evaporator the brine water mixed with anti freeze glycol or ethanol releases its energy to the refrigerant which is vaporised in order to be compressed in the compressor the refrigerant of which the temperature has now been raised is passed to the condenser where it gives off its energy to the heating medium circuit and if necessary to the water heater if there is a greater need for heating hot water than the compressor can provide there is an integrated immersion heater 14
- Pipe connections 14
- Pipe installation must be carried out in accordance with current norms and directives f1255 can operate with a return temperature of up to 58 c and an outgoing temperature from the heat pump of 70 65 c with only the compressor 14
