Heating system — what it meansWhat 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 underfloor heating ('Electric Floor' diagram, load on the relay terminals). GA (water floor) and GC (boiler, dry contact) are different SKUs [1] |
|---|---|
Floor temperature limit — what it meansThe 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. | 10–70 °CSetting 9 'High temperature protection': 10–70 °C, default 45 °C. The manual does not explicitly tie it to the floor probe; external-sensor limiting works in AL mode [1] |
Setpoint range — what it meansThe temperature you can set, from minimum to maximum. The lower limit matters for keeping the home frost-free while nobody is in. | 5–35 °C5–35 °C per the technical data. In settings the lower limit can be raised to 15 °C (item 5) and the upper limit set from 15 to 45 °C (item 6, default 35 °C) [2] |
Hysteresis (dead band) — what it meansHow 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. | 1–5 °CSetting 2 'Deadzone temperature', default 1 °C [1] |
Weekly schedule — what it meansHow 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)Maker's infographic: 5+2, 6+1 and 7-day modes; the manual programs each weekday separately, although one line of the manual says 'weekdays + weekend' [2] |
Schedule periods per day — what it meansHow 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. | 66 periods per day; the site says 'up to 42 schedules a week' (7 × 6) [1] |
Functions — what it meansExtra 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, frost protection, eco mode, settings kept after power lossButton lock (full or all but power), low-temperature protection 0–10 °C (item 8, off by default), economy mode with its own 0–30 °C setpoint, settings kept during power loss [1] |
On-device controls — what it meansHow you operate the device without a phone: touch buttons on glass, mechanical buttons or a rotary knob (ring). | Touch buttons [1] |
| Clock error | less than 1 % [2] |
Maximum load current — what it meansThe 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 the GB (electric heating) version; GA and GC are rated 5 A [2] |
|---|---|
Supply voltage — what it meansThe supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter. | 95–240 V AC, 50/60 HzA 24 V version also exists; the actual voltage is printed on the back. The GB diagram shows AC 95–240 V [1] |
Standby power — what it meansHow 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 [2] |
Connectivity — what it meansThe 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. | Wi-Fi, MatterMatter over Wi-Fi, 2.4 GHz only. Bluetooth on the phone must be on while adding the device [2] |
|---|---|
Hub required — what it meansWhether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise. | No hub neededConnects directly to a 2.4 GHz Wi-Fi router; Apple Home, Google Home, Alexa and SmartThings need their own Matter controller [1] |
Matter support — what it meansWhether 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. | Built-in [2] |
Home Assistant — what it meansHow the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration. | Via a separate integrationThrough the Matter standard (Home Assistant Matter integration). Moes does not mention Home Assistant separately [2] |
Voice assistants — what it meansWhich voice assistants the maker states the device works with. This usually needs an internet connection and, for Zigbee devices, a hub. | Amazon Alexa, Google Assistant, Apple Home (Siri)The maker also lists Samsung SmartThings (via Matter) [2] |
Transmit power — what it meansThe 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. | 16 dBm [1] |
Wi-Fi band — what it means2.4 GHz passes through walls better and reaches further, but is more often crowded by neighbours' networks. 5 GHz is faster and less congested but weaker behind walls. A 2.4 GHz-only camera won't join a network that runs on 5 GHz only. The Wi-Fi generation (e.g. Wi-Fi 6) is in the note. | 2.42.4 GHz only [1] |
App — what it meansThe maker’s app used to set up and control the device. | MOES App, Tuya Smart / Smart Life; Apple Home, Google Home, Amazon Alexa, SmartThings (Matter) [1] |
Sensor modes — what it meansWhich 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 limitSetting 4: In — internal sensor, Ou — external sensor, AL — air control with the external sensor as limit (default AL) [1] |
|---|---|
Sensor calibration — what it meansHow 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. | −9 °CSetting 1 'Temperature compensation', for the internal sensor [1] |
Temperature accuracy — what it meansPermitted 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 [2] |
| Sensing element | NTC3950, 10 kΩ [2] |
| Temperature display range | 5–70 °C [2] |
Floor probe included — what it meansWhether 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. | YesPacking list on the site: 'Floor Sensor 1pc (For GB version only)'. The manual calls the sensor optional [2] |
|---|---|
Manufacturer warranty — what it meansThe 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 meansWhat comes in the box, per the maker. | Thermostat, 2 screws, user guide, floor sensor (GB version only) [2] |
Neutral wire (N) — what it meansWhether 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 L and N terminals [1] |
|---|---|
Mounting — what it meansHow 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 box86 × 86 mm square box or European 60 mm round box; fixing hole spacing 60 ± 2 mm [1] |
Dimensions (W × H × D) — what it meansThe device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf. | 88 × 88 mm, 12.4 mm above the wall; in-wall part 50 × 50 mmThe depth of the in-wall part is not given on the drawing [1] |
Ingress protection (IP) — what it meansProtection 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] |
| Recommended wire gauge | 2 × 1.5 mm² or 1 × 2.5 mm² [1] |
Colour — what it meansThe housing colour of this model. Other colours in the same series are separate products. | WhiteOn the maker's page the GB version is offered in white only (SKU …-WH-…) [2] |
|---|
Operating temperature — what it meansThe air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms. | 0–45 °C [2] |
|---|---|
Operating humidity — what it meansThe rated relative humidity range, non-condensing. | 5–95%Non-condensing [2] |
| Storage temperature | −5…45 °C [2] |
