Danfoss TP5000Si Wired 5/2 Day Programmable Thermostat 087N791000 HARDWIRED NOT RF

This was bought to replace a damaged unit, plugged straight into the original back plate and all good.I considered going all hi-tech wifi remote Startrek style but this model works a treat and would be a bargain at double the price.I'd give it five for ease of use and if you don't want to change the offered programme it's fine but I get bored following the instructions and endlessly prodding buttons is worse than entering details in a tacho first thing in the morning

I bought this to replace a decade-old thermostat that had started acting up. It was a like-for-like swap, so no wiring or electrical work needed. I pulled the old one off (leaving the original base unit on the wall) and popped this one on. Easy peasy, was up and working within seconds. It comes with a little guidebook to help set up timings, etc. which was appreciated.Tip: pay close attention to where the pins on the bottom right hand corner fit into the unit when you're pulling the original off. I wouldn't have had a clue otherwise where they lined up.

Used as a direct replacement for a mechanical central heating thermostat to automatically control day and night time temperatures. Would have liked 6 time periods but 4 is OK. Installation was easy but setting up time periods and temperatures required trial and error as instruction booklet is tiny and not clear, and even the pictorial instructions on the flap of the device itself appeared to be in a foreign language.. Overall, good value and is now helping to save on fuel bills.

The battery had leaked in my existing device, corroding away the circuit board. Hence, this unit was a rescue for me. Replacement was easy as I did not have to bother about the base plate. Left the older one fixed on the wall and just replaced the new device onto the old base plate.Started working like new straightaway and could readjust the programme to suit our heating needs.

This is easy to install and was bought as a replacement to my faulty one. These are easy to install and work but they tend to be faulty around the 2.5 year mark. so if you buy, be prepared to change every 3 years.

Like for like replacement for our existing thermostat which had developed a fault.

Brought this to replace one with a faulty thermostat, took minutes to install and works great

Excellent value, clear display and works well but the unit supplied was slightly inaccurate (+1.5 degrees celsius) compared to reference thermometer) and the instructions omitted to explain what all the displayed icons meant, otherwise 5 stars.
