Electric Relay

In stock

The Electric Relay switches the load for various heating, cooling and ventilation sources. It has no exposed buttons making it ideal for commercial applications.
Often installed behind a fused spur so it cannot be tampered with by occupants in the room, normally it is used to control Air Conditioning or Ventilation (HVAC) systems to the schedule setup on the app, or it can also be used to react to occupancy in a zone, switching off AC and HVAC units, saving energy when zones are not being used. For HVAC applications the temperature will be measured by a Room Sensor or Room Thermostat. Alternatively, this can be used to switch any load up to 11A 230V, using its volt- free contact.

As it is mains-powered, the Electric Relay always boosts the signal forthe other devices in the property. This increases the life of the battery powered devices by providing easy lines of communication back to the Smart Master Controller.

The Electric Relay is shipped with a Blanking Plate & One Gang Pattress.
