Connecting the clock thermostat for the circ-
ulation pump
Circulation pump control
Normally a room thermostat is used controlling the starts
and stops of the circulation pump. When the set room
temperature is reached, the circulation pump is stopped
and starts again when the temperature drops. For connec-
tion see diagram “Electrical connections” – “Connecting
the room thermostat”.
The circulation pump can even be operated manually. No
room thermostat will be connected. Instead the circulation
pump is operated by the switch (18) on the front panel.
The mode “Auto” does not permit any operation of the
circulation pump if no room thermostat is connected. The
switch in position “On” permits permanent operation of
the circulation pump.
Current, fuse
The maximum current is 16,7 Ampere. Therefore a 20
Ampere fuse shall be used. NOTE! Relevant electrical stand-
ards must be considered.
Immersion heater
F205P is delivered with a 3 kW immersion heater (1). It is
started and stopped via the microproessor card (34). If a
failure occurs there is a temperature limiter (6) (thermal
cut-out) that is stopping the immersion heater. An immer-
sion heater without a temperature limiter is not allowed to
be mounted.
Connect the supplied clock thermostat to terminal block
(9) and (11) according to the image below.
Set switch, circulation pump (18) to ”auto”.
Set the clock thermostat according to the ”Settings” sec-
tions.
