THR840DEU DT2 Thermostat, White

Easy to install, item as described. Easy to use, excellent value for money. Good quality for the price. Basic but does the job great and looks better than my previous thermostat. Would recommend

Accurate and consistent performance. This thermostat comes with a good range of adjustable parameters for those who want to personalise their heating controls. Easy to install and attractive piece of kit.

A direct swap for a failed unit, much cheaper than Screwfix plus next day delivery. Fitted in less than five minutes and working as it should. There is an updated version so probably in short supply

Bought this to replace my tired looking analog dial thermostat. Does exactly what it says on the tin.

Simple but excellent. And it works! Not the prettiest or trickiest thermostat but it works! And it's accurate. And the time feature is great for cold days when you're out or bedtime - so you can drop the temps only for them to raise again. Bought this unit previously. Didn't trust anything else with "toys" so bought it again.

Unfortunately, very much a fail. I had high hopes for this product. It cost me £50 to have it installed and even when commanding 16C, as I always did with my analogue thermostat, it’s throwing out max heat all day, every day. No other changes made to my programming. Can’t recommend

The installation was relatively straightforward however the instructions leave a lot to be desired. There isn't an adequate description of the various menu options for instance. Two complaints: – there should be a heating indicator I.e. heating relay active – on mine it does not appear (could be a firmware problem) – backighting on remote Would be eminently sensible even if for when you adjust/check

I first bought this particular room thermostat from a local DIY store. My old analogue type was inefficient, it had a huge hysteresis so the boiler 'would never switch off' unless the house temperature was way above the level that was set. This digital thermostat, easy to install, is very efficient and switches the heating on and off at the correct temperature. ( a separate thermometer proves this). My daughter's family had similar problems in their house so I tried to get them the same item. The local DIY store had stopped selling this particular item and only stocked items that were more complicated and more expensive. I opted for the Amazon store to find the same model I had purchased. Bingo! Bought it, installed it into my daughter's house. My son-in-law is over the moon with the result. So much more efficient and their boiler is running less than before. Some people have reported difficulty in opening the device. I had no problem, but being an engineer found it easy. To remove the cover, for access to the batteries, place your thumb on the bottom of the unit, fingers on the top, and 'twist' down. Cover easily removed. For access to the electrics and fixing screws. Isolate the 240v mains to the unit from the boiler control or main switch for safety. Use a small screwdriver blade to 'gently' release the 2 top locking tabs at the top for the middle case to be lifted clear. Done. To reverse the procedure, 'Click' the middle case back. To replace the front case: place the bottom in first and then twist top back in. Pull to check it has locked. Done.

Prodotto valido, fa il suo dovere

Muy sencillo y facil de usar, cumple su función

Prodotto molto semplice sia da programmare nei parametri più avanzati (facoltativo), sia da impostare per il funzionamento di base. Come da descrizione non è un cronotermostato quindi si imposta solo una temperatura costante, ma per la mia esigenza è proprio ciò che cercavo.

It working...

Le produit n'est pas en 230V mais à piles 2 piles AA,mensonge sur le produit. Et un contact NO et ON. Sinon bon produit.
