Notes
Check the settings of DIP switches no. 1 through no. 8 of the RCU60 / RCU60.1 and of
DIP switches no. 1 through no. 6 of the RCU61.0 / RCU61.1. If setpoint limitation is
required, use the minimum and maximum limitation facility (energy saver).
After applying power, the controller makes a reset, which takes about 3 seconds. Then,
it will be ready to operate.
Before the controller (RCU61/61.1) starts its control action, it performs a three-position
synchronization of the actuator. As a result, the actuator will be fully opened and then
closed again. This process takes 400 seconds. Then, the controller will be ready to
operate.
The controller is supplied with Mounting Instructions.
Mounting location: on a wall of the room to be heated or cooled. Not in niches or book-
shelves, not behind curtains, above or near heat sources and not exposed to direct
solar radiation. Mounting height is about 1.5 m above the floor. The connecting wires
can be run to the controller from a recessed conduit box.
Only authorized personnel may open the controller.
When mounting the unit, fix the baseplate first. Then, make the electrical connections
and fit and secure the cover.
The controller must be mounted on a flat wall and in compliance with local regulations.
If there are thermostatic radiator valves in the reference room , they must be set to their
fully open position.
The room temperature controller is maintenance-free.
