Commissioning and adjusting
Preparations
Before commissioning, check that the heating circuit is filled
and well vented. Check the pipe system for leaks.
Filling and venting the heating medium system
The heating medium system is filled with water to the re-
quired pressure. Vent the system using the venting nipple
on the enclosed flexible hose and possibly the circulation
pump.

Balance temperature
The balance temperature is the outdoor temperature when
the heat pump’s stated output is equal to the building’s
output requirement. This means that the heat pump covers
the whole building’s output requirement down to this tem-
perature. Setting of the balance temperature, additional heat,
is made on channel A5.
Stop temperature
When the stop temperature (channel A7) is set between -7
and -15 °C the flow temperature is limited linearly from -7 °C
/ 55 °C to -15 °C / 45 °C.
Soft-start relay
F2015 is equipped with a soft-start relay (97) that limits the
inrush current for the compressor.
The compressor must not be forced to start with periods
shorter than 1 start per 15 minutes.
Compressor heater
F2015 is equipped with a compressor heater that heats the
compressor before start-up and when the compressor is cold.
The compressor heater must have been connected for 6 - 8
hours before the FIRST start, see the section “Start-up and
inspection”.
NOTE
The compressor heater must have been connected for
6 – 8 hours before the first start, see the section “Start-
up and inspection”.
