Designed to take over from the ChannelPlus range by using the same wall plate with minimal wiring changes, whilst bringing connectivity features along the way. It is Bluetooth-enabled and works with a mobile app as well as the provided programable thermostat. This unit is ideal for replacing traditional wired controls for systems that require separate control of heating and hot water or multiple heating zones. It is compatible with the standard 9-pin backplate offered with our popular Horstmann ChannelPlus making retrofits and new installs easy.
This smart programmer can even control the schedule of an existing wired thermostat and is designed to be modular and expandable with extra sensors for more heating zones. There is no hub or gateway to configure and power for remote access; simply plug the Wi-Fi card into the front slot, provide the password via the app and you will be connected. The H3747 also includes many of the latest Boiler Plus energy-saving features such as optimum start and stop per heating zone, as well as on-off load compensation. This significantly improves boiler efficiency by preventing short-cycling and overshooting of temperature and helps to save more energy and improve efficiency.
