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 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).
The configuration is now finished and the differential thermostat is enabled.
Remark:
The cooling will stop when the bedroom temperature reaches the preferred setting of its selected mode (anti-freeze,
night, day or comfort).
