The short version: The TH1300ZB is Sinopé’s directly-wired Zigbee thermostat for electric floor heating, rated up to 3600W at 240V with a built-in Class A GFCI and load-detection that lets it double as a general smart controller for other resistive electric loads beyond floor heating. For a single bathroom or kitchen floor-heating zone within its wattage rating, it’s a simpler, cheaper install than the low-voltage TH1400ZB.

Who It’s For

The TH1300ZB is built primarily for electric in-floor (radiant) heating — the mats or cables under tile, hardwood, or laminate in bathrooms, kitchens, and basements. Unlike the TH1400ZB, it switches line voltage directly rather than requiring an external relay, which makes it a more straightforward single-thermostat installation for a standard-size floor-heating zone.

It also detects the type of load connected to it and can be used more generally as a smart controller for other resistive electric loads up to its 3600W rating — which is where the “load controller” framing sometimes attached to this model comes from, even though Sinopé markets it primarily as a floor heating thermostat.

Design & Build

Standard Sinopé housing: a white rectangular unit with a backlit LCD display and physical buttons for manual adjustment without the app.

Setup & Compatibility

Voltage and load: Operates at 120/208/240V. Maximum load is 1800W at 120V, 3120W at 208V, or 3600W at 240V (15A). Check your floor-heating mat’s total wattage against these limits before buying — for a larger installation exceeding 3600W, look at the TH1400ZB with an external relay instead.

Control modes: Configurable for ambient temperature control, floor-only control, or ambient control with a floor-temperature limit, using a connected floor sensor.

Built-in GFCI: Class A ground-fault protection (5mA) is built in, appropriate for wet-location installs like a bathroom floor circuit.

Setpoint range: 5°C to 36°C, with ±0.5°C resolution.

Hub requirement: Zigbee 3.0, requiring Sinopé’s GT130 gateway and the Neviweb app.

Warranty: 3 years.

Installation: Turn off the breaker, verify power is off with a voltage tester, and follow the Neviweb app’s wiring diagram. This is more straightforward than the TH1400ZB since there’s no external relay to size and wire, but it’s still line-voltage work — hire a licensed electrician if you’re not confident with it or your local code requires one.

App & Ecosystem

Runs through the Neviweb app: scheduling, away/vacation mode, frost protection, and per-device energy reporting in kWh. If you’re already running Sinopé baseboard thermostats on the same GT130 hub, this integrates onto the same dashboard.

Smart home support: Alexa and Google Home via SmartThings or Neviweb integration; Samsung SmartThings natively; no Apple HomeKit on any Sinopé model.

Buyer Feedback: What We Found

Sinopé’s manufacturer documentation and retailer listings (Amazon.ca/.com, Guillevin, and Sinopé’s own support site) for the TH1300ZB are thorough and consistent, and it’s sold at higher volume than the more specialized TH1400ZB. We found limited independent long-form review coverage specific to this model number — most available information is spec sheets and retailer product pages rather than owner write-ups or forum threads. Treat the buying guidance here as grounded in verified specs rather than a large body of independent reviews.

Price & Value

TH1300ZB
Price (CAD) ~$100–150

Subscription None

Cheaper and simpler to install than the TH1400ZB for a standard single-zone floor-heating job, since there’s no external relay to buy or wire.

Rebate Eligibility

Sinopé’s floor-heating thermostats have appeared on Énergir’s rebate qualifying list in past program years, though eligibility for electric floor-heating models specifically is less consistently listed than for baseboard thermostats. Verify current lists with your utility before purchasing.

Pros & Cons

Pros:
– Switches line voltage directly, no external relay needed for standard installs
– Built-in Class A GFCI, appropriate for bathroom/wet-location circuits
– Load-detecting design lets it double as a general resistive load controller
– Integrates onto the same Neviweb/GT130 ecosystem as other Sinopé devices
– 3-year warranty; cheaper than the TH1400ZB for a standard-size install

Cons:
– 3600W ceiling means larger floor-heating zones need the TH1400ZB instead
– Requires the GT130 hub, an added cost and setup step
– No Apple HomeKit
– Limited independent review coverage beyond manufacturer and retailer documentation

The Recommendation

Buy the TH1300ZB for a standard single-zone electric floor-heating install (bathroom, kitchen) within its 3600W rating, especially if you’re already invested in the Neviweb/GT130 ecosystem through other Sinopé thermostats. For larger installs or two-stage setups, see our TH1400ZB review instead.

Frequently Asked Questions

What’s the maximum load the TH1300ZB can handle?
3600W at 240V (15A), or 1800W at 120V. Check your floor-heating mat’s total wattage against this before buying.

Does the TH1300ZB need an external relay?
No. Unlike the TH1400ZB, it switches line voltage directly, which makes it simpler to install for a standard-size floor-heating zone.

Is this a floor heating thermostat or a load controller?
Primarily a floor heating thermostat, but its load-detecting design means it can also be used as a general smart controller for other resistive electric loads up to 3600W.

Does it need a hub?
Yes, Sinopé’s GT130 Zigbee gateway, same as the company’s other Zigbee thermostats.

Does it have built-in GFCI protection?
Yes, Class A (5mA), appropriate for bathroom or other wet-location floor-heating circuits.

Is the TH1300ZB eligible for Canadian rebates?
It has appeared on Énergir’s qualifying list in past program years, though eligibility for floor-heating models specifically is less consistent than for baseboard thermostats. Verify current lists with your utility.
