Sunydog Heat Pump Thermostat 4.3" Display

The Sunydog smart thermostat controls air-source and ground-source heat pumps in homes, offices, villas and hotels. A 4.3 inch colour LCD shows indoor temperature, outdoor temperature, target temperature, system mode, fan mode, time and weather. Six touch buttons provide local control while built-in Wi-Fi enables remote adjustment through the Tuya or Smartlife mobile app. Voice commands are supported via Amazon Alexa and Google Home integration.

Suits Heat Pump Systems With App Control

This unit suits owners of compatible heat pump installations who want programmable scheduling and remote access from a smartphone. It is not for buyers who need line-voltage or millivolt control, and it is not for installations that lack a 24V DC/AC power supply. The controller also does not support systems requiring proprietary brand communication protocols outside the stated voice-assistant integrations.

24V Power And 62mm Or 86mm Mounting

The thermostat operates on a 24V DC/AC supply and mounts using either a 62±5mm hole pattern common in Europe, China and Japan or an 86±3mm pattern used in the USA and Italy. An NTC395 sensor handles temperature measurement. These electrical and mechanical requirements determine whether the device fits the existing wiring and wall box.

Questions about this item

What Wi-Fi standard does the thermostat use and what does that limit in practice?

The built-in Wi-Fi module connects to the Tuya or Smartlife app for remote control and voice commands via Google Home or Amazon Alexa; no Wi-Fi version is specified.

Which wall-box spacings does the 17.0 in x 12.5 in x 6.0 in unit support for mounting?

It fits three patterns: direct wall mount, 62±5 mm centres (Europe, China, Japan) and 86±3 mm centres (USA, Italy).

How is the 24 V DC/AC thermostat wired and what step do installers often miss?

Connect the 24 V supply to the labelled terminals, match the heat-pump wires to the corresponding terminals, then snap the unit onto the mounted base; the step often missed is verifying the NTC395 sensor reading in the app before finalising.
