ON/OFF ELECTROTHERMIC ACTUATORS
Description
2
The electrothermic actuators 22CX series are ON/OFF devices used for automatic actuation of the valves on:
- thermostatic adaptable valves series 178UM, 1178UM, 179UM, 1179UM, 188UM, 1188UM, 189UM, 1189UM,
130UM, 131UM, 102M, 100M, 120B
- fan coil valves series 2131, 3131, 4131
- manifolds series HKV and 822M
The electrothermic actuators are available in the following versions:
• NA (normally open)
• NC (normally closed)
• 2-wire or 4-wire (with auxiliary microswitch).
Both easy to fix on the valve body with a M30 x 1,5 threaded ring nut.
The thermostatic actuators are designed for on 24 V and 230V power supply (see below table)
.

Application
The electrothermic actuators series 22CX 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 series 22CX 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 4-wire version is
provided with an auxiliary contact for additional features (metering, control of pump, fan or other equipment).
The actuator has a trasparent zone that allows for checking the status of the actuator.
Red = valve closed - Black = valve open.

Installation
Electrothermic actuators 22C series can be selected according to the type of system, installation space and power supply.
In systems with 2-way control valves fitted with electrothermic actuators it is advisable to install by-pass valves
in (466 series or USVR series) to ensure a minimum recirculation of the mean..

ON/OFF ELECTROTHERMIC ACTUATORS
Mounting
1) Remove handle or cap from the valve body.
2) Place the actuator and manually tighten the ring nut of the actuator onto the
body valve.
DO NOT use pipe wrenches, spanners or similar.
3) Connect electrical wiring.

Important maintenance notes
Do not remove the cable. Opening the 22CX series actuator will cause
irreparable damage to the device.
Faulty actuators must be replaced as complete sets.
Warning
IP54 is for horizontally or vertically mounting.
