Passive cooling of a bedroom
During summer time the bedroom is cooled via a fan that extracts air from a cooler room.
Mount a temperature sensor in both rooms. The temperature sensor of the bedroom is set to cooling mode and the
cooling output is linked to a relay channel that controls the fan.
When the temperature in the cooler room is about 3 degrees lower than the bedroom temperature the fan is activated.
Configuration:
The easiest way to configure the system is to use the Velbus link program via a PC connected on the Velbus PC interface
(VMB1USB, VMB1RS of VMBRSUSB).
However, configuration can also be done without the aid of a computer. Refer to the procedure below.
Link the cooling output of the bedroom sensor to a relay channel (ex. channel1).
1. Set the bedroom 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 1 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 relay module to ‘C1’. The
‘MODE 1’ LED flashes to indicate push button
learning mode (PBM).
