changing thermostat sunvic 2000 TLX to sunvic TLX RFP (RX)

[dale094]

Could anybody help , I want to change room thermostat from a
sunvic 2000 TLX to a sunvic TLX RFP (RX) WIRELESS RECIEVER

The timer is a Horstmann 425 tiara I intend to leave progammer on constant for heating so that the stat does the work or switching for heating and water when demanded can be on or off with switch at programmer


The boiler is a baxi solo

any help diagram would be helpful.

Thanks.

The new stat will come with a wiring diagram. What additional diagram do you need?

i take it the boiler is for heating only and hot water is from sperate cylinder upstairs so original thermostat is for heating only.

Does this help? http://www.sunvic.co.uk/downloads/p...ostats/tlx-rfd-userinstallation-instructions/. If not let us know what system you have at the moment and how your existing stat is connected. I'm sure someone can help.
