The RXA29.1 room controller consists of a housing base, a housing cover and the
printed circuit board. The printed circuit board incorporates the connection terminals
and the DIP switches used for configuration. The controllers also have a potentiometer
for setpoint adjustment and testing, and a Service LED with different flashing patterns
to indicate operational status and test states.

Terminal covers (RXZ20.1) are available as an option, to protect the connection
terminals from physical contact and dirt. The Service LED and the potentiometer
remain visible even with the terminal covers fitted. The potentiometer can be operated
with a screwdriver. The cable is connected to the room controller by breaking out the
perforated cable entry guide.
