Honeywell DT90E Digital Room Thermostat + ECO is rated 4.35 out of 5 by 80.
Rated 5 out of 5 by from Simple improvement on existing Easy to fit and good instructions. Excellent product
Date published: 2016-10-12
Rated 3 out of 5 by from Needs better user manual. This is a sophisticated control unit but the instructions do not explain the features. For example the unit switches on or off below or above the set temperature depending on the rate of temperature rise or drop. This can be adjusted (pb -proportional band width value and temperature offset- tO.) Why no info on how to use these & the other parameters? The unit is easy enough to fit and wire up (2 wire) but I think it needs some optional backlight illumination as its difficult to read in a dark area. Also removing the unit from the wall baseplate requires 3 hands. The battery cover in contrast comes off too easily - not child proof. Otherwise it's fine!

Rated 5 out of 5 by from Digital Room Thermostat Easy to fit, wiring obvious, display good, intuitive to work, good to be able to read the room temperature at all times. Operating instructions could be fuller and clearer.

Rated 4 out of 5 by from Tricky, but good overall. ...bit of head scratching to figure out the wiring diagram as its not clear what configuration you should go with and the operating instructions and description of functions are poor. Having said that, after you have figured it all out, it looks great. Nice neat simple and updated look and accuratley monitors the room opposed to the dial solutions you can buy. All in all, thumbs up.

Rated 5 out of 5 by from suits 2 wire or 3 wire had a bit of a cafuffle to understand fully the wiring requirement but sussed it. I had 3 wire set up on previous thermostat... this new unit only requires the live and the switch wire. I didnt need the neutral. Its because its a battery operated unit and only needs a circuit made to switch on or off. neutral just terminated behind unit. neat tidy simple digital thermostat. Nice.

Rated 1 out of 5 by from Noisy Two things wring with this: 1. When I got it home, I could see it had already been used (screwdriver marks on the case tags and the battery was already running). Not happy, but if it works OK then I wouldn't really mind. 2. It is REALLY NOISY! The regular CLUNK noise as it turns on and off in the lounge is more than a bit irritating. It is much louder than the stat it replaced. Based on the above, it's going back to Screwfix ASAP for a refund (selling me something that isn't NEW is enough to ensure I can get a refund). For the price I expected something better than this. Will go for another brand.

Rated 4 out of 5 by from Good replacement Used to replace old honeywell manual thermostat. Managed to have same screwholes and was a simple replacements. Just use live and switched live. Neutral and Earth are redundant. Would have liked a backlight. Seems to be accurate.

Rated 5 out of 5 by from Excellent unit Replacement for 2 wire bimetallic strip unit. Good quality, excellent instructions and 10 mins fitting time. Wish I'd bought this years ago. Highly recommended.
