STARTING-UP WITH VENTILATION ONLY
It is possible to run FLM S45 with only ventilation, e.g.
before the brine side is ready for connection. In this
mode, the circulation pump must be switched off.
1. Follow the instructions on page 23 , but leave the
switch for circulation pump (SF2) in "0" mode.
2. When the brine side is connected, the switch for
circulation pump (SF2) is set to "1" mode.
SETTING THE VENTILATION
7.1.4.1.
The ventilation must be set according to applicable
standards. If FLM S45 is connected to a compatible heat
pump, the setting is adjusted in menu 7.1.4.1. Otherwise
the ventilation is set via potentiometer (AA5-SF3).
Even if ventilation is roughly set at installation it is im-
portant that a ventilation adjustment is ordered and
permitted.
NOTE
Order a ventilation adjustment to complete the
setting.

SETTING THE BRINE FLOW
Set the brine flow so that the temperature difference
between the brine entering and leaving FLM S45 is
2–4°C. The temperature is measured using external
measuring equipment.
Compatible heat pump: The brine flow over FLM S45
is regulated by the trim valve (RN1) and the circulation
pump (GP2).
Other heat pumps: The brine flow over FLM S45 is
regulated by the trim valve (RN1) and the brine pump in
the heat pump.
Adjustments are made when the heat pump is in oper-
ation. Temperature difference applies at 20 °C room
temperature and 0 °C in the brine.
The brine flow through FLM S45 will be from 0.1 l/s (360
l/h) to 0.15 l/s (540 l/h) at the above temperature differ-
ence, depending on the ventilation flow.
When the heat pump is at a standstill, the internal circu-
lation pump in FLM S45 gives from 0.085 l/s (306 l/h) to
0.125 l/s (450 l/h) in the return charging flow to the col-
lector.
This applies to a heat pump with approximately 4 kW
rated output.
For a 15 kW heat pump, the corresponding flow is from
0.09 l/s (324 l/h) to 0.14 l/s (504 l/h).
SETTING PUMP SPEED
Set the speed of the circulation pump (GP2) in menu
7.2.2. For other heat pumps, the trim valve (RN1) is used
to set the flow.
