Room controller with display and two outputs
for valves with three-point actuators
RC-DTO is a room controller from the Regio Mini series, intended to
control heating and cooling in a zone control system. The controller
has four digital outputs for controlling two valves with three-point
actuators (increase-decrease), and a display. Installation is directly
on the wall or on an electrical connection box. The controller does not
have a communication connection.

Installation
Place the controller in a location that has a temperature representative for
the room. A suitable location is approx. 1.6 m above floor level in a place
with unobstructed air circulation.
Remove the frame by depressing the locking tab in the lower edge of the
cover with a screwdriver. See figure 1.
Then prize out the electronics cassette using the four rectangular screwdri-
ver slots and levering against the edge of the bottom plate. See figure 2.
Note: Take care not to damage the electronics when inserting the screw-
driver into the slots.

The bottom plate with terminals has a number of fixing hole combina-
tions. Select suitable holes (see figure 3) and screw the bottom plate onto
the wall or connection box, so that the arrows on the bottom plate point
upwards. Do not tighten the screws too hard!
With surface-mounted cabling, break-out suitable holes from the marks in
the plastic.
