Introduction
This fan-coil thermostat control kit CH130ARR
is made up of a CH130AR thermostat and a
DIN bar CH172D actuator.
The CH130AR model is a fan-coil 4- or 2-pipe
thermostat that allows you to control the ambi-
ent temperature both in the heating and cool-
ing mode. These commands are sent to a
CH172D actuator connected to the CH130AR
by means of a two-pole cable.
The CH130AR is powered directly by the ac-
tuator and is able to drive two valves and also
control a 3-speed fan-coil motor, either in man-
ual or automatic mode.
The thermostat measures the ambient tem-
perature either through an internal probe or an
external sensor. It keeps the set-point by act-
ing on the ventilation speed.
The wide display shows the measured tem-
perature, the fan speed, the program being run
and the selected season.
The settings and data are store in a permanent
memory that will retain them even when the
thermostat is not connected to the CH172D.
