Allocate a relay channel for the circulation pump
Some valves have a contact that closes when the valve is open. By wiring all the contacts in parallel, the circulation
pump can be steered.
For valves that do not have these contacts, a relay can be assigned to the temperature sensors to steer the
circulation pump.
In this example the pump must be active as soon as one of the sensor modules indicates heating is required. This can
be done e.g. through relay channel 1 of a relay module.
1. Set all sensor modules in anti-freeze mode by
pressing the push button on the front panel
repeatedly until all LEDs are off.
2. Set the MODE and TIME1 rotary switches for
channel 1 of the relay module to ‘0’ (instant
control).
3. Remember the address of this relay module to
reinstate it later on.
4. Set the address of the relay module to ‘C1’. The
‘MODE 1’ LED flashes to indicate push button
learning mode (PBM).

5. Press and hold the pushbutton on the front panel of
the first sensor module and simultaneously press
and hold the lowest push button (HEAT) until the
relay is energised and the red LED on the sensor
module flashes. First release the lowest push
button (HEAT) followed by the push button on the
front panel.
6. Press and hold the pushbutton on the front panel of
the second sensor module and simultaneously
press and hold the lowest push button (HEAT) until
the relay is energised and the red LED on the
sensor module flashes. First release the lowest
push button (HEAT) followed by the push button on
the front panel.
7. Repeat step 5 for all other sensors.
8. Set the address of the relay module back to its
original value.
