Control and features10

Heating system — what it means What the thermostat output is rated for according to the maker. Electric underfloor heating connects directly through the thermostat relay, water underfloor heating through an actuator or pump, and a boiler through its room-thermostat input.	Electric underfloor heatingVersion GB is for electric heating ('Electric Floor' diagram, load on N1/L1). GA (water floor) and GC (boiler, dry contact) are different SKUs [1]
Floor temperature limit — what it means The upper floor-temperature limit above which the thermostat cuts heating even if the room is still cool. Protects laminate, parquet and tiles. Shown as the adjustable range; works with the floor probe.	Not stated by the manufacturer
Setpoint range — what it means The temperature you can set, from minimum to maximum. The lower limit matters for keeping the home frost-free while nobody is in.	5–35 °CThe functions section of the same manual says 5–45 °C and the app has a 45 °C setpoint ceiling [1]
Hysteresis (dead band) — what it means How far the temperature must drift from the setpoint before heating switches on again. A smaller value gives a steadier temperature but more frequent relay and boiler cycles. Shown as the adjustable range.	Not stated by the manufacturer
Weekly schedule — what it means How the schedule stored in the device is organised: each day separately, 'weekdays + Saturday + Sunday', or 'weekdays + weekend'. 'App only' means the hub or cloud runs the schedule, so it stops working without a connection.	Each day separately (7 days)The maker's infographic shows a schedule with Mon–Sun day selection; the manual's default program is the same for every day. The schedule is set in the MOES app [2]
Schedule periods per day — what it means How many times a day the device changes the setpoint by itself following the schedule. A typical weekday has 4–6 changes: wake-up, leaving, coming back, night.	4Manual: 4 periods per day (same in the infographic) [1]
Functions — what it means Extra modes stated by the maker: child lock, frost protection (the boiler starts if the home gets too cold), open-window detection, eco mode, holiday mode, boost heating and keeping settings after a power cut.	Child lock, eco modeChild lock (on the device and in the app), energy-saving mode with a temperature set in the app (default 30 °C) [1]
On-device controls — what it means How you operate the device without a phone: touch buttons on glass, mechanical buttons or a rotary knob (ring).	Rotary knob or ringRotary knob with a round screen; pressing the screen opens the menu and confirms [1]
Menu languages	9: English, Chinese, Spanish, French, Italian, Polish, German, Russian, Portuguese [2]
Clock error	less than 1 %; time syncs over the internet [1]

Power3

Maximum load current — what it means The current the built-in relay can switch. For electric underfloor heating at 230 V, 16 A corresponds to roughly 3.6 kW; more powerful cables or mats are connected through an intermediate contactor.	16 A16 A for GB (diagram: 'Imax 16A'); GA and GC are 5 A [1]
Supply voltage — what it means The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.	95–245 V AC, 50/60 Hz [1]
Standby power — what it means How much power the device draws on its own while idle. It matters for devices that run around the clock.	1.5 WLess than 1.5 W [1]

Connectivity and compatibility9

Connectivity — what it means The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.	ZigbeeZigbee 3.0 (IEEE 802.15.4), 2.405–2.480 GHz [1]
Hub required — what it means Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.	Hub requiredMaker: the ZigBee version requires a ZigBee gateway, sold separately [2]
Matter support — what it means Whether the device supports the Matter standard, directly or through a bridge. Matter lets you add it to Apple Home, Google Home, Alexa and Home Assistant.	NoThe specs list Zigbee only; Matter support or use via a Matter bridge is not described by the maker (the Matter mention in the page FAQ is copied from the Matter model) [1]
Home Assistant — what it means How the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration.	Via a Zigbee coordinator or hubFollows from Zigbee 3.0: via a Zigbee coordinator. The maker does not mention Home Assistant [1]
Voice assistants — what it means Which voice assistants the maker states the device works with. This usually needs an internet connection and, for Zigbee devices, a hub.	Amazon Alexa, Google AssistantVia the Zigbee gateway and the MOES/Tuya cloud [2]
Processor / radio chip — what it means The microcontroller or radio module inside, per the maker (for example ESP32). For firmware such as WLED and ESPHome it determines available features and whether the device can be re-flashed.	ZT3L module [1]
Radio frequencies and transmit power	2.405–2.480 GHz (IEEE 802.15.4) [1]
Transmit power — what it means The coordinator's maximum radio output. Higher power gives a steadier link to distant devices, but range in a home depends more on walls and the number of routers in the network.	20 dBm [1]
App — what it means The maker’s app used to set up and control the device.	MOES App, Tuya Smart / Smart Life [1]

Measurement and detection5

Sensor modes — what it means Which temperature the thermostat regulates by: air (the built-in sensor), floor (a remote probe in the screed), or air with a maximum floor-temperature limit.	Air (built-in sensor), floor (remote probe), air with floor limitSensor types: In — internal, Ou — external, AL — internal sensor controls, external sensor limits [1]
Sensor calibration — what it means How many degrees the built-in sensor reading can be offset by hand if it reads higher or lower than a room thermometer, e.g. −9…+9 °C.	Not stated by the manufacturer
Temperature accuracy — what it means Permitted error of the built-in sensor, ± °C. A value of 1 means that at 21 °C in the room the thermostat may show anything from 20 to 22 °C.	1 °C [1]
Sensing element	NTC3950, 10 kΩ [1]
Temperature display range	5–99 °C [1]

Package contents3

Floor probe included — what it means Whether the box includes a wired remote temperature probe, laid in a conduit in the screed. For electric underfloor heating it is needed for floor mode and to protect the floor covering from overheating.	YesSite packing list: 'External temperature sensor cable (For GB version only)' [2]
Manufacturer warranty — what it means The warranty period the maker states. Confirm warranty terms in Moldova with the seller.	24 monthsWarranty terms printed in the manual, from the date of purchase [1]
Package contents — what it means What comes in the box, per the maker.	Thermostat, external temperature sensor cable (GB version only), manual; the manual also lists 2 screws [2]

Housing and installation5

Neutral wire (N) — what it means Whether the wall box needs a neutral wire. Older wiring often brings only the live wire to the switch; then pick a model that works without N.	RequiredThe wiring diagram feeds power to the N and L terminals [1]
Mounting — what it means How and where the thermostat is installed. In Moldova round Ø60 mm wall boxes (the European standard) are the most common; square 86 × 86 mm boxes are rarer. Surface and desktop versions need no wall box.	Round Ø60 mm wall box, Square 86 × 86 mm wall boxStandard 86 mm box or European 60 mm box [1]
Dimensions (W × H × D) — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	frame 86 mm, total depth 55.5 mm (knob 16 mm in front of the frame, in-wall part 30 mm); knob Ø46.3 mmFrame height is not dimensioned; in-wall body height 48.4 mm [1]
Ingress protection (IP) — what it means Protection against dust (first digit) and water (second). IP20 is for dry rooms only, IP44 resists splashes, IP65 and up handle water jets and outdoor use.	IP20 [1]
Housing material	PC + ABS, fireproof [1]
