We recommend using the input of the V-belt supervision as a release for the step
switch when entering an overrun time for the step switch. This ensures that an
electric heating coil is switched on only with flow.
The external release takes priority over a signal from frost protection or from
preheating. In other words, an electric heating coil can be decoupled from the frost
function.
10.7.6 Modulating output
The output signal of the modulating output (Y) can be limited high and low.

Inversion Yes, No
No
Meaning:
 No: 0...100% Load = 0...100% output
 Yes: 0...100% Load = 100...0% output
