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).
Use the relay channel (ex. Channel2) to control the fan.
