The new C1727 is a receiver / PTD unit (1 or 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.

With load compensation algorithm that significantly improves boiler efficiency by preventing short-cycling and overshooting of temperature when used with programmable thermostat display (PTD). Load compensation has been shown to save energy compared to traditional systems, while maintaining more consistent comfort levels.
 

  • 3A Volt Free Operation
  • 12-Year battery life on wireless control
  • Optimum start and stop
  • Local override
  • Load compensation for efficiency and comfort
  • Optional Service Interval reminder
  • Bluetooth Installer and user app (Android and iOS)

  • It will not fit onto the existing backplate, but connect to the same wires.

  • Hi

    Yes, you can replace it with the C1727.  

    It will fit the existing backplate, you will just need to place an electrical link between L and 2 on the backplate.

  • Hi.  No, you will need to change the backplate.  It will connect to the same 4 wires.


  • This would replace your programmer.  You could then link out the Centaurstat 7 to make the wireless display act as the thermostat.

    The receiver is mains powered, and the wireless display is battery powered.

    You will need the optional WiFi card to control it when away from home.

  • It is not a direct replacement.  It will need to be wall installed and wired by a heating engineer.

  • This will be suitable to replace.  A minor wiring change to the backplate will be required.

  • Hi.  Yes, it can be used to replace a Horstmann H21XL.

  • Yes, it will plug straight on for a simple swap.

  • It has volt-free connection.  For mains, link L to common.
  • Yes.  If you need WiFi (i.e. control away from home) then you will also need the WiFi card.  HCO Code 16E10.

  • Yes you can.  If you need control when away from home you will also need the WiFi adaptor card.  HCO Code 16E10
  • Hi.  The batteries are non-replaceable, and last around 12 years.

  • Hi It has 6 temperature changes per day, which is equivalent to 3 on/off periods per day.
