Schneider Electric CCTFR6000

Compatibility

Compatible with EpiSensor Edge over Zigbee.

Pair it with the Zigbee radio on an EpiSensor Gateway. Edge reads it locally on the Gateway.

Edge reads 25 values from it, listed under Interface.

Specifications

Schneider Electric sells this controller as the Wiser Underfloor Heating Controller or Connection Strip. The Heat/Cool version is CCTFR6600 and the Heat version is CCTFR6610. It sits beside the manifold and switches the thermal actuator heads that open and close the flow to each underfloor loop. It also has a volt-free boiler contact on B1 and B2 and a switched pump output on L2 and N2.^1, 3

Power

Mains. 230 V AC ±10 %, 50 Hz, from a 3 A supply to L and N. A 24 V AC version, CCTFR6620, needs its own 24 V, 2.2 A supply.¹

Where it is used

• Boiler firing demand from the boiler relay, logged beside fuel and heat meters to compare the periods when the heating system is actually called.

  Boiler performance monitoring

• Heat pump systems with underfloor emitters, where the Heat/Cool version can also switch the heat pump and each zone’s demand explains its run time.

  Heat pump performance monitoring

• Zone control of underfloor heating in offices, clinics and apartments, with Edge setting each channel from a Zigbee room sensor and a schedule.

Interface

Readings and settings, with units and ranges where Schneider Electric publishes them. R readable, R·W readable and writable.

Setting a channel’s state to ON does nothing while its demand is 0. For plain on and off switching, set demand_percentage to 100 once and then switch the channel with its state. Endpoints 7 and 8 leave the factory at a demand of 100.²

There is no fail-safe if control stops. A demand stays in place until it is overwritten, and Zigbee2MQTT’s notes record one persisting for over 40 minutes. Whatever regulates the channels must also switch them off, or send ON with an on_time so the channel turns itself off.²

Demand and cycle time sit in a Schneider Electric manufacturer-specific cluster. The converter reads and writes them on every endpoint, with demand from 0 to 100 % in 1 % steps and cycle time from 300 to 3,200 s.³

The converter exposes no temperatures. The heat probe input on T1 and T2 and the floor temperature limit belong to the Wiser app’s configuration, not to this definition.^1, 3

Setup

1. Wire and power it first

   Wire the actuators, pump and boiler contact, and power the controller before pairing. The QR label on the controller carries its EUI-64 address and install code.¹

2. Open pairing in Edge

   In Edge, open pairing on the Gateway’s Zigbee network so the Gateway accepts new devices.

3. Reset it

   Hold the setup button for more than 15 seconds until the LED flashes red, and keep holding until the flashing stops. A reset removes the whole controller, every channel, from a Wiser Hub.²

4. Join the Gateway

   Hold the setup button again until the LED flashes green, then wait a few seconds for the controller to join. Check that Edge identifies it as Schneider Electric CCTFR6000.¹

5. Prove one channel

   Set demand_percentage on channel 1 to 100 and its state to ON. The channel LED lights when its relay closes and calls for heat. Switch it OFF again before you configure the rest.¹

Common questions

Does the CCTFR6000 need a Wiser Hub to work with Edge?

No. Zigbee2MQTT supports it directly, so it pairs with the Zigbee radio on an EpiSensor Gateway without a Wiser Hub. Resetting it to pair with the Gateway removes it from any Wiser Hub it was on.²

Why does a channel stay off when I switch it on?

A relay closes only while the channel’s state is ON and its demand_percentage is above 0. Set the demand to 100 for plain switching, or to a lower value for time-proportional control within the cycle time.²

What happens if Edge or the network stops?

The controller keeps the last demand until it is overwritten, so a channel left ON keeps heating. Send ON with an on_time, or make sure the control logic switches channels off. If the controller loses power, its normally open relays release and the valves close.^1, 2

Does it measure room or floor temperature?

Not through this definition. The controller switches valves, pump and boiler, and room temperatures come from separate sensors. Its heat probe on T1 and T2 serves the Wiser system’s floor temperature limit and is not exposed over Zigbee here.^1, 3
