Boiler Frost Protection for C-plan.

pcr · 12 Nov 2014

I am planning frost protection using the Honeywell kit on our boiler which is in the garage and is piped as a C-plan. It is recommended to fire the boiler and pump (connect frost/pipe stat to terminal 5) but that will leave the gravity hot water circuit with no circulation (m/v de-energised). Is this something to be considered or will heat conduction in the pipes be sufficient ?
Thanks.

With just a quick look; you could always connect 4 & 6 with a STDP relay controlled by the Frost/Pipe thermostat. That should pull on everything without any back feeds.
