Circuit description
All units need a 230 V AC power supply.
A lockable repair switch is always fitted and connected to the electrical housing.
Factory-fitted actuators are wired to the terminals. The appropriate terminals are available for valve actuators.
Only 24 V DC valve actuators Open/Closed can be connected.
The speed of the EC fans is controlled by a 0-10 V DC signal from the KaControl. The “intelligent” motor electronics de-
tects any possible motor malfunction and automatically switches off the fan.
The cooling valve (Y1) is actively closed in the event of a condensate alarm.
A motor malfunction signal is available to the potential-free contact f.e1/f.e2 (30 V DC / 2 A).
A condensate alarm is available to the potential-free contact c.a1/c.a2 (30 V DC / 2 A).
The control board has various LEDs for the visual display.
It also features a micro-fuse.
