Function
F1145 prioritises hot water charging. The
heat pump is controlled by the outdoor
sensor (BT1) in combination with the in-
ternal flow sensor. The internal immersion
heater is connected automatically when the
energy requirement exceeds the capacity of
the heat pump.
Heating system 2
The external circulation pump (EP21-GP20)
is dimensioned for the under floor heat-
ing system's demand. The flow through
the heat pump is adjusted using the heat
medium pump and any applicable control
valve.
NOTE!! In cases where the system volume
in the heating system is below 20 l/kW
(compressor output) and/or heating me-
dium flow is choked uncontrolled, a UKV
tank is installed as a volume increaser. For
only under floor heating systems and UKV,
3 connections on the UKV tank must be
used according to its installation instruc-
tions.
Note! This is an outline diagram. Actual
installations must be planned according to
applicable standards.
See the appropriate "Installer manual" for
more information.
