Programmable Thermostat For Combi Boiler BOT-R8X

This wireless boiler thermostats typically consist of two components: a controller and a receiver.

The controller is primarily powered by AAA batteries, allowing it to be installed anywhere conveniently, without needing to be near an electrical outlet. It's also equipped with a USB port, allowing it to be connected to an adapter or power bank via a USB charging cable. This not only provides a backup power source but also allows users to charge the thermostat whenever needed or use it directly from AC power, making it ideal for desktop or mobile use.

The receiver requires a stable 110-230V AC power source. This is because it needs to continuously send control signals to the boiler and may need to drive internal relays to switch it on and off, both of which require relatively high power. Therefore, the receiver typically needs to be connected to the home's main power line and will be wired by a professional during installation.

The wireless room heating thermostat and its receiver have a range of 30 meters. This distance provides excellent flexibility in most home environments. You can place the thermostat anywhere in the house that's comfortable or convenient, without worrying about connecting it to the boiler's receiver.
One of the biggest advantages of wireless thermostats is the lack of wiring. The 30-meter communication range means you can avoid the complexities of running control wiring through walls, greatly simplifying installation and allowing for greater flexibility in thermostat placement.

The 30-meter control range offers significant convenience for wireless thermostats, allowing you to flexibly control your home's heating system. However, understanding and considering factors that may affect communication will help you achieve a better user experience.

The wiring diagram for this daily program room thermostat on the left is for controlling a gas wall-mounted boiler, normally open or normally closed electric thermal actuato and a heat pump for hydronic heating system.

While the wiring diagram is clear, it's recommended to seek professional assistance during installation to ensure all devices are connected correctly to avoid short circuits and damage to the equipment caused by incorrect wiring.
