Allocate a relay channel for the high temperature alarm
The sensor module can also control a relay when room temperature should reach extreme high values. This situation
might occur when a heating valve is broken e.g. it does not close anymore causing the room to keep heating up. The
relay contact can than be used e.g. to switch on a warning light or activate an audible warning signal.
As an example, relay channel 3 of a relay module is used.
1. Set the sensor module 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 3 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 ‘C3’. The
‘MODE 3’ LED flashes to indicate push button
learning mode (PBM).
