Smart WiFi Heating Thermostat by Saswell


Compatible with Google Alexa

EAN: N/A SKU: Wifi_Thermostat_Saswell Category: Tag:

This wireless communication thermostat can replace most common residential thermostats and is designed to be used with gas, electric and oil heating systems. Compatible with Google Home and Amazon Alexa smart home voice control systems using the Tuya and Alexa apps. This thermostat can be used for connection directly to a traditional boiler or combination boiler to control when the heating is turned on/off. It can also be connected to a pump/valve in order to control heating temperature and on/off times to one specific part of a building, for example when zoning ground floor and first floor of a typical house for separate heating control. This thermostat is normally used to replace an existing thermostat or in a new heating installation. A wire does need to be run from the position of this wall thermostat to the heating boiler to control the heating on/off signal.

2 Part Thermostat. (The 2 parts communicate with each other using wireless radio communication)
Part 1 – The Screen, which is wireless battery powered wall/ free standing, with wifi communication.
Part 2 – Receiver which is all mounted next to the boiler and receives the wireless radio signal from the wall thermostat, with wifi communication.

The air temperature sensor is inside part one, the screen. The screen is usually positioned in a central location such as a ground floor hallway away from windows or cold draughts. The screen detects the air temperature. When the set temperature is reached, the screen sends a wireless radio signal to the receiver located next to the boiler. The receiver has a relay inside which then cuts the power to the boiler to turn off the heating and vice versa. The receiver is wired to two terminals inside your heating boiler. You will have to check online to find your boiler manufacturers installation manual to confirm where these terminals are located. If a heating thermostat has not been connected to your boiler before, there will usually be a loop wire which needs to be removed. If in doubt, consult with an electrician or heating installer.
