Specifications

It is built for wet heating systems: Schneider rates it for water at 73 °C continuously and 110 °C at most, on a valve whose surface stays at or below 93 °C. It works in rooms from 0 to 45 °C and is rated IP30, so it belongs indoors in dry rooms.¹

Power: Battery. Two 1.5 V AA alkaline cells, supplied with the thermostat.¹
Setpoint range: 5 to 30 °C, 0.5 °C steps¹
Local adjustment: Twist cap, ±2 °C¹
Valve connection: M30 × 1.5 ring nut; adapter for Danfoss RA valves¹
Heating water: 73 °C continuous, 110 °C maximum¹
Valve surface temperature: 93 °C maximum¹
Operating temperature: 0 to 45 °C¹
Storage temperature: -10 to 55 °C¹
Relative humidity: 25 to 90 % operating¹
Wireless: Zigbee, 2.4 GHz, 13 dBm (20 mW) maximum¹
Radio range: 0 to 30 m¹
Protection: IP30, pollution degree 2¹
Dimensions: 51 mm diameter, 93 mm high¹
Standards: EN 60730-1, EN 60730-2-7, EN 60730-2-9, EN 300 328¹

The thermostat reports its model as CCTFR6100 and uses the standard Zigbee thermostat cluster: local temperature, occupied heating setpoint, PI heating demand and running state.³

Its Zigbee definition writes the setpoint from 7 to 30 °C in 1 °C steps, a narrower range than the 5 to 30 °C the head accepts locally.^1, 3

Heating demand is the valve position: 0 % is fully closed and 100 % fully open. Running state reads heat while it is calling for heat and idle otherwise.²

Setup

Fit it to the valve
Screw the supplied M30 × 1.5 ring nut onto the valve, or fit the Danfoss RA adapter first on an RA valve, then mount the head.¹
Insert the batteries
Fit the two AA alkaline cells supplied with it.¹
Open pairing in Edge
In Edge, open pairing on the Gateway’s Zigbee network and put the thermostat into pairing mode as its leaflet describes. A thermostat already joined to another Zigbee network, such as a Wiser system, has to leave it or be reset first.
Check one reading and one setting
Confirm Edge identifies it as Schneider Electric CCTFR6100Z3. Compare the local temperature with a thermometer in the room, then write a setpoint a few degrees above it and check the heating demand rises.
