6 Application The electrothermic actuators C, CX, CX, LC Series are used for ON/OFF control of the heat emission of terminal control units in heating and air conditioning systems, through an electric signal transmitted by a thermostat. The use of electrothermic actuators instead of pure thermostatic actuators allows remote control. The room thermostat or control component controlling the system can be positioned in the most suitable point of each room to provide regulation and wired back to the electrothermic control head. Operation Operation of the electrothermic actuators C, CX, CX, LC Series is powered by on a wax thermostatic element assembled into in the actuators and activated by a PTC thermistor against a signal sent by a room thermostat or timing thermostat. When the thermostatic element expands, it supplies the thrust required for the movement of the valve. The -wire version is provided with an auxiliary contact for additional features (metering, control of pump, fan or other equipment). The actuator has a transparent zone that allows for checking the status of the actuator (only for C, CX and CX Series) Red = valve closed - Black = valve open. About the LC Series, for using with devices that have an electrical consumption higher than microswitch limits, use an additional relay. Two LEDs (visible only when lighted) are positioned on top of the actuator: the green LED shows the power supply presence and the blue LED shows when the valve is open. Installation Electrothermic actuators C, CX, CX, LC Series can be selected according to the type of system, installation space and power supply. In systems with -way control valves fitted with electrothermic actuators it is advisable to install by-pass valves in ( Series or USVR Series) to ensure a minimum recirculation of the mean. Mounting To install the actuators follow these steps: 1. remove the protective cap, if present, or handwheel from the valve (or manifold outlet). screw-in the actuator ring nut by hand on the threaded part of the valve body and lock it. connect the wires to the power supply. insert the plug in the actuator connector (only for LC Series)

7 Maintenance Do not remove the cable. Opening the C, CX, CX, LC Series actuator will cause irreparable damage to the device. Faulty actuators must be replaced as complete sets. Warning C Series. The actuator has an degree of protection IP in vertical position. IP Warning CX, CX Series. IP is installed in any position respect to the valve body. IP 0 IP 0 IP 0 Warning LC Series. Protection class IP allows to install the LC in any position respect to the valve body. The removable cable allows easy mounting, maintenance and replacing. Pull the connector pressing the safety latch to take it out from the socket.
