AKV info !!
230 V a.c. coil
AKS 32R info
The signal from one pressure transmitter can
be received by up to ten controllers.
There cannot be a signicant drop in pressure
between the pressure transmitter’s position in
the suction line and the S2 temperature in the
individual evaporators.
Capacitive load
The relays cannot be used for the direct connection of capacitive loads such
as LEDs and on/o control of EC motors.
All loads with a switch mode power supply must be connected with a suit-
able contactor or similar.
