Wiring diagram for electric damper actuator
Connect the control signal from the room thermostat to
input Y (wire marked 3). Output U is a true value signal.
Design power consumption: 5 VA, applies to BLB motor
and RTC.

Electric actuator control signals
The diagram below shows the mixing damper blade posi-
tion in relation to the control signal, electric. 100% denotes
full cooling. 0% denotes full heating. For the best control,
the room thermostat should be set for mixing box control,
i.e. have its neutral position at 5V. On the RTC, this func-
tion can be selected using the LUNA T-CU hand-held termi-
nal. See the commissioning instructions for the RTC.
