Can it switch an electric baseboard directly?

Not directly. Its outputs are rated 1 A at 24 V AC, so an electric baseboard, fan heater or floor is switched through a mechanical relay or a solid-state relay. For direct switching at line voltage, Sinopé makes the TH1123ZB and TH1124ZB.

Does it report energy use?

No. It reports temperatures, heating demand and heating state. The connected load values are settings that tell it the heater wattage, not measurements.

Is a floor sensor included?

No. Floor control and floor limits need the optional AC1310-01 sensor or another 10 kΩ or 12 kΩ sensor. A mode, the default, works without one.

How do I remove it from a Zigbee network?

Hold the up and down buttons together for 10 seconds. The network icon disappears from the display.

Specifications

It suits the heating systems a line-voltage thermostat cannot switch: hydronic underfloor heating, hydronic radiator circuits and furnaces, as well as electric heating on a contactor or solid-state relay. Sinopé states that it cannot be used with a cooling system or a heat pump. A relay may be needed with hydronic floors, hydronic systems and furnaces.^1, 3

Main output: 1 A maximum¹
Auxiliary output: 1 A maximum¹
Compatible heating: Hydronic floor and radiator systems, furnaces without fan control, electric heaters through a relay or SSR³
Not for: Cooling systems and heat pumps³
Cycle length, main output: 15 s, or 5 to 30 min in 5 min steps; 15 min default²
Cycle length, auxiliary output: Off, 15 s, or 5 to 30 min; off by default²
Control modes: A (air, default) or F (floor)²
Setpoint range: 5 to 36 °C¹
Display range: 0 to 70 °C¹
Resolution and accuracy: ±0.5 °C³
Floor sensor: Optional AC1310-01; accepts 10 kΩ or 12 kΩ at 25 °C¹
Output polarity: Normally open (default) or normally closed²
Storage temperature: -20 to 50 °C¹
Wireless: Zigbee 3.0, 2.4 GHz, +20 dBm transmit, -108 dBm receive sensitivity, AES-128¹
Warranty: 3 years¹

Where it is used

Zone heating demand from hydronic underfloor and radiator circuits, lined up against boiler firing and fuel use.
Boiler performance monitoring
Room and floor temperature records in offices, apartments and hotels with wet heating.
Indoor environmental monitoring
Changing setpoints and schedules across many zones from one place, without visiting each thermostat.

Occupied and unoccupied heating setpoints are written in 0.5 °C steps from 5 to 36 °C, inside the minimum and maximum setpoint limits. System mode is off or heat.⁶

The Zigbee definition offers main-output cycles of 15 seconds and 5, 10, 15, 20 and 30 minutes. The thermostat’s own menu also has 25 minutes.^2, 6

Connected load and auxiliary connected load tell the thermostat the heater wattage on each output, from 1 to 20,000 W. They are settings, not measurements: this model reports no power or energy.⁶

Setup

Wire it with the power off
With the 24 V AC supply off, connect the supply, the main output and, if used, the auxiliary output and floor sensor to the terminals shown in Sinopé’s wiring layout for your heating system. A relay may be needed for hydronic systems and furnaces.²
Mount it and power up
Fix the base to the wall with the screws and anchors supplied, replace and lock the cover, and switch on the supply.²
Set the cycle and polarity
Set the main output cycle to at least the minimum Sinopé’s guide gives for the equipment on that output. Set the output polarity if the valve or relay needs a normally closed signal. Both can also be changed from Edge after pairing.²
Join the Zigbee network
Open pairing on the Gateway’s Zigbee network in Edge, then press the thermostat’s two buttons briefly at the same time. The network icon blinks while it connects and stays lit once it has joined.²
Check one reading
Confirm that Edge identifies it as a Sinopé TH1400ZB. Raise the setpoint and check that the heating state changes to heat and the valve or relay operates.
