Allocate a relay channel to control the fan
In our example, the fan of the convector must be switched on when the temperature measured by the third temperature
sensor deviates too much from the desired value. The fan is steered by relay channel 2 of the second relay module.
1. Set the third 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 second 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 second relay module to ‘C2’.
The ‘MODE 2’ LED flashes to indicate push button
learning mode (PBM).
