DIN RAIL WIRED ACTUATOR FOR FAN COIL ROOM THERMOSTAT
CH176D
1 - INSTALLATION
The device is designed for installation on DIN rail, but its small size facilitate the installation inside the fan coil also.
ATTENTION!
The end parts (live) of the CH176D must be installed in a container or fan coil inaccessible by the user.
Installation must be carried out by qualified personnel, in compliance with the requirements concerning
installation of electrical devices. Make sure that the power network is disconnected before making any
connections or working on the device.
The following figure shows the circuit diagram of the connections.
The distance between the actuator module and thermostat must not exceed 100 metres.
In air conditioning systems with four pipes, valve 1 (terminals N and V1) controls the heating circuit while valve 2 (terminals
N and V2) controls the cooling circuit.
The temperature sensor (NTC 10KΩ) must be connected to the PROBE input. The 0 ... 10V motor must be connected to
the specific 0-10V OUT output, respecting its polarities.
