Hard Wired Controls - 24V Output

FH-WC 24

• Incorporates separate boiler and pump interlocks

• Convenient and easy to wire floor heating connection box

The central component in the FH-WC 24 hard wired control range is the wiring centre ideal for use in water based floor heating systems.

FH-WC is a connection box for use in hydronic floor heating systems supplied from a manifold.

FH-WC is a wiring centre for connecting up to

10 thermal actuators to the room thermostats.

It is provided with two potential-free relays for controlling a circulation pump and a boiler. The relays are activated when one or more thermostats require heat.

FH-WC is connected to 230 VAC/50 Hz.

Mounting is made easy due to the symbols printed on the screw terminals.

FH-WT 24 dial setting room thermostat used for single room temperature control and temperature setting can be maximum and/or minimum limited. A LED light behind the front cover indicates heat demand.

FH-WS is a room thermostat with manual night set-back and optional connection for a floor sensor. If a floor sensor is connected min. or max. regulation is selected with a switch depending on the type of floor i.e. wooden floor (max.) or tiles (min.). The thermostat is provided with thermal feedback to improve accuracy. LED behind front cover indicates heat demand.

Temperature range is 6 - 30°C.

FH-WP is a tamper proof model of the FH-WS for use in public environments i.e. schools. The thermostat is used for single room temperature control. The thermostat is provided with thermal feedback to improve accuracy. LED behind front cover indicates heat demand. Temperature range is 6 - 30°C.
