FAN COIL ROOM THERMOSTAT
CH130ARR2
OPERATING MODE SELECTION
If thermostats CH133RR - CH130RR - CH130ARR are connected to the actuation module, it must be configured in CH172D
mode. The selection is made by switching on the actuation module by means of the configuration of the probe input
according to the following diagram:
CH176D
: probe input free or connected to a temperature probe
CH172D
: temperature probe input permanently short-circuited by means of a conductor cable
LUMINOUS STATUS INDICATOR
The CH176D unit is equipped with a status indicator made via a two-coloured LED diode.
Flashing red:
the actuation module is configured as Master and is receiving a command from the
thermostat.
Flashing green:
the actuation module is configured as Slave and is receiving a command from the
thermostat.
Flashing red and green
alternately:
protection. After twenty minutes during which the actuation module does not receive
commands from the thermostat, the relays are deactivated and the 0 ... 10V output is
brought to 0V. Upon reception of a command, the actuation module resumes normal
operation.
COMMISSIONING AND OPERATIONAL CHECK
Commissioning and testing procedure:
■
make sure that the actuator is properly connected to the thermostat;
■
set the “BUS selector” to ON (MASTER);
■
set up the actuation module as CH176D or CH172D (according to the thermostat connected to it);
■
supply 230Vac power to the actuator;
■
check that the thermostat is turned on;
■
by consulting the manual of the thermostat, set it in the different operating modes (winter and summer) with
consistent set-points and gradually select the various ventilation speeds (1, 2 and 3), check switching of the various
relay and the subsequent actuations of the V1/V2 valves and the fan coil motor.
