Connections and Principle of Operation

The wiring connections for TWS is shown below




This requires 1 Input and 1 output in Comfort.

The Comfort Input is connected to the Current Sensor of the TWS so that the current on/off state of the light is known by Comfort. Any Input can be used. The Input/Zone should be programmed as Switch Normally Open Zone Type.

The Comfort Output is connected to the Lighting Relay (rated at 6 amps) in the TWS to switch the light on or off. Any output can be used for this.

The Live wire supplying the light is connected to the TWS "L" connector after passing through the center hole of the Current transformer (loop 2 times).

The Relay Contacts (Normally Open and Normally Closed) are connected to the Two Way Switch terminals (S1 and S2). The "common" terminal of the two way switch is connected to the light.

Thus for every light switch to be controlled in this way, 2 electrical wires are required between the Two way switch and the TWS module which is normally located near Comfort.

In essence the TWS Relay acts as another two way switch for the lighting circuit. Hence it can be seen that either Comfort  or the two way switch can switch the light on and off.
