Hortsmann / Secure C1727 2-Channel Smart 2-Channel Wireless Controller
The C1727 is a 2-channel smart programmer that can control heat pumps, combi, and system boilers. Out of the box, it is Bluetooth and app enabled and has the option of a plug in Wi-Fi adapter to give complete smart control. The C1727 is designed to supersede the CentaurPlus and ServicePlus range of time switches and programmers by using the same wall plate with minor wiring changes, providing 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; simply plug the Wi-Fi card into the front slot, provide the password via the app and you will be connected.
The C1727 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.
