Rated 5 out of 5 by Great replacement thermostat Bought as a replacement for the original room thermostat. Used these before (sadly unit used before - Horstmann - no longer available), this one looks to be up to the job. Batteries included (2 X AA) - bonus. Easy to fit, backing plate has a range of fixing holes, went straight up, no drilling required. Unit has the advantage that it comes pre configured with factory settings. Just remember to turn off mains supply before you start -easy DIY job. 28 Mar 2016
Rated 4 out of 5 by Great for Underfloor heating Easy to install, wire up. Preset times and temps make it easy to programme. 16 Jan 2016
Rated 1 out of 5 by Misleading description Pretty disappointed to find that you cannot make different settings on different days of the week... described as "6 temperature and time changes per day " this is in fact not the case - you can only make settings identical every day Too soon to comment on anything else 7 Nov 2015
Rated 5 out of 5 by TP4000 This was a great choice to replace the Danfoss TP4 as it fitted exactly in the same fixing holes and the electrical connection is the same and with it being double insulated it didnt need the 2 core cable to be changed to 3. Well worth every penny. Also £30 cheaper at Screwfix compared to a plumbers merchant. Good job all round. 17 Dec 2014

Hello, I need to replace the ServoWarm TP5E due to it dying. I understand ServoWarm is now Danfoss and wondered if this unit was wireless or hard wired.

If this unit is not a suitable replacement, can you advise of one that is?

good morning , if your unit has TP5E-RF on the front it is a wireless thermostat and the replacement is the TP5000si-RF and RX1 receiver. If it is Just a TP5E it should be replaced by the TP5000si

The existing Danfoss wall thrrmostat needs renewing. If i buy Tp4000 will it work as soon as batteries installed or will the wiring need changing also?

if the previous unit was a TP4000 and was wireless (RF) with batteries, then you will need to power it up and 'pair' it up with the RX-1 receiver. Please call 01234 320254 if you need further assistance.

Many Thanks
