The C1727 is a 2-channel smart programmer that controls heat pumps, combi, and system boilers. It is Bluetooth and app-enabled, and this item has the plug-in Wi-Fi adapter already installed for complete smart control. The C1727 is designed to supersede the Centaur Plus and Service Plus range of time switches and programmers by using the same wall plate with minor wiring changes, providing the benefits of extra connectivity. The C1727 can easily control a single or double heating zone, or heating and stored hot water system. You can even control the schedule of an existing wired thermostat or add extra sensors to a spare zone to give further control. There is no hub or gateway to configure and power for remote access.
