The new C1727 is a receiver / PTD unit (for managing up to 2 channels)
which can control combi or system boilers.
Out of the box it is wireless enabled and can be controlled by an app.

With the optional Wi-Fi adapter, it can fully control your heating system outside of the home via the app.

Ideal for replacing traditional wired controls for systems that require separate control of heating and hot water or up to two heating zones. It is compatible with standard 6-pin backplate offered with our popular CentaurPlus and ServicePlus timer, programmer range.
