Introduction
This fan-coil thermostat control kit CH130RR
is made up of a CH130R thermostat and a DIN
bar CH172D actuator.
The CH130R model is a fan-coil 4- or 2-pipe
thermostat that allows you to control the
ambient temperature both in the heating and
cooling mode. These commands are sent to a
CH172D actuator connected to the CH130R
by means of a two-pole cable.
The CH130R is powered directly by the
actuator and is able to drive two valves and
also control a 3-speed fan-coil motor, in
manual mode.
The thermostat measures the ambient
temperature either through an internal probe
or an external sensor. It keeps the set-point by
acting on the ventilation speed.
The wide display shows the measured
temperature, 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.
