The Fan functions


Fans that are not compatible with the TDS13522 (2 wire fans), can be controlled using individual relays (MICROS+, TDS13510, …). There are two fan types available:

4-wire single phase AC motor
relays are switched in an OR configuration. For Low speed the relay for Low is on and the others are off. Etc. At all times, maximum one relay is switched on by the fan function.
universal fan control
relays are switched in an AND configuration. For Low speed, only the relay for Low will be on. For Med, the Low and Medium are on, etc.
Make sure that no other functions control the relays used for the fan.
The number of available speeds can be set from 1 to 3 (+OFF).

Function behaviour

The operation is identical to the operation of the fan.
