The digital display shows the actual room temperature, the ON / OFF times and the
symbol of the operating mode currently active. When the heating output is active, the
triangle symbol appears.
When taking out the batteries, the setpoints and the information required for operating
mode changeover are retained for maximum 2 minutes.
Ordering
When ordering, please give name and product number: Room temperature controller

Mechanical design
The controller consists of 3 parts:
•Plastic housing with digital display accommodating the electronics, operating ele-
ments and built-in room temperature sensor
•Baseplate (mounting base)
•Removable battery compartment
The housing engages in the baseplate and snaps on. The baseplate carries the screw
terminals. There is a reset button on the rear of the unit.

Notes
Mount the room temperature controller in a location where the air temperature can be
acquired as accurately as possible without getting adversely affected by direct solar
radiation or other heat or refrigeration sources.
Mounting height is about 1.5 m above the floor.
The unit can be fitted to a recessed conduit box.
When mounting the unit, fix the baseplate first. Then, make the electrical connections
and fit and secure the controller (also refer to separate mounting instructions).
Mount the controller on a flat wall and in compliance with local regulations.
If there are thermostatic radiator valves in the reference room, set them to their fully
open position.
The controller is maintenance-free.
If the battery symbol appears, the batteries are almost exhausted and must be re-
placed.
To reset, press the reset button on the rear of the unit. All individual settings are then
reset to their default values.
