Fan output 

In this section, the function charts and application explanations for the fan outputs are explained. 

 

4.1.1 

Fan operation 

In fan operation a single phase fan, blower or convector can be controlled. In combination with a valve 
control 2, 3 or 4 pipe system can be implemented. The fans are controlled via a 3 stage speed controller. 
For this purpose, three windings are tapped off the fan motor. The resulting fan speed is dependent on the 
tapping selected. It must be ensured that two contacts are not switched on simultaneously. For control 
purposes, at least one 3 stage changeover switch with zero position is usually used. This switch is mapped 
with a group of outputs in the device.
