VMB1TS manual – edition 2
Allocate a relay channel for the low temperature alarm
The sensor module contains an anti-freeze protection, but when the heating system is down it is still possible that the
temperature in a room drops. To warn the user that the room temperature reaches freezing point a relay can be
energised. This relay channel can be used e.g. to switch on a control light or an electrical heater.
As an example relay channel 2 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 2 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 ‘C2’. The
‘MODE 2’ LED flashes to indicate push button
learning mode (PBM).
