Pro Honeywell Wireless Programmable Thermostat CM927 CM921 CM727 Replacement Central Heating Programmer Boiler Plus Compliant, White, Standard

A well designed easy to first replacement for a broken Honeywell cm927. It even used the same screw holes in the wall. Worked first time

Easy to set up (followed the video link) and works perfectly, think it might automatically change times ie. Back to GMT as I manually altered the device back an hour but this morning it was back 2 hrs😂

I needed to replace an existing obsolete Honeywell thermostat. This is compatible with my existing receiver unit, so I didn’t need to get an electrician to install the receiver that was provided. Instructions on how to pair weren’t great so I googled instructions and it worked. Programming was very easy and the unit has a stand so it’s portable.

Worked like a wonder as a replacement for a previous one. Great stuff

I liked it very much nice to be warm again and it's installed and doing what it is suppose to do.

Arrived ahead of time but packaging had obviously previously been opened as Sellotape cut and items inside in disarray . Binding instructions were missing and had to search on web and you tube to eventually find instructions on how to bind to existing relay box. I was considering returning but this was already a replacement as previously lid had been faulty although other one was obviously new and had all contents. Now all seems to be working well 🤞looks good and temperature seems well controlled.

Easy to use and worked straight away. Nice neat control.

I ordered this to replace the remote thermostat of my 12yr old system . Its advertised as a compatible replacement but I was worried that it might not communicate with my existing wall transmitter attached to my boiler. In fact it’s incredibly easy : Just unclip the front of the old wall transmitter and clip the new one in. Fits exactly. No tools . No rewiring . No programming of the new transmitter . Brilliant.
