ZED-TTR-HA Zigbee Thermostat

This thermostat contains a 240v relay to switch the heating off and on and talks back to the Omni Controller viw Zigbee. It provides current temperature and heatsetpoint to the Omni that can be set vioa the OT7 touchscreen or the app. This thermostat shows up under thermostats in PC Access.

Use this thermostat to replace a traditional thermostat for radiator based heating by simplky replacing the mechanical thermostat on the wall. This switches 240v to the 3 way valve making it a plug and play replacmenet.

Use this thermostat with under floor heating by poistioning the thermostat in the room and run a switched live back to the actuator for that room.

Use this thermostat with electric undefloor heating using the switched live to power the under floor heating matts.

In all situations full control is available via the Omni via Zigbee wireless communication.
