Honeywell DT90E Wired Digital Room Thermostat

The Honeywell DT90E Wired Digital Room Thermostat leads the way in energy efficient control by using advanced technology to maximise the energy efficiency of the heating system. The Honeywell DT90E Wired Digital Room Thermostat has been designed to provide automatic temperature control of gas or oil fired boiler systems, underfloor heating, electric heating and zoning systems.  

Energy efficiency is addressed by state of the art control performance qualifying it as a Load Compensator. The Honeywell DT90E Room Stat has an ECO button energy saving feature which gives timed setback or boosts temperatures to reduce energy demand.
 
The Honeywell DT90E Digital Room Stat is a TPI (Time Proportional Integral) control product as defined in the Building Regulations, which make boilers operate more efficiently and provide close accurate control.
 
It also incorporates an ‘OFF’ setting that can be used for frost or hypothermia protection, assuming the system time control is also switched on. 'Installer Mode' also allows control to be matched to the system and user requirements, adapting minimum on or off times, set point controls etc.
 
Two wire, volt free connections are ideal for use with combination boilers or heating zones.

5/ 5

Pros: It does exactly what it was purchased for!!

Cons: The installation instructions are really difficult to understand, and even momentarily confused my friend, who is actually an electronic engineer

The product does everything it is supposed to do..and more. Once I had figured out the instructions, which were extremely difficult to understand, the actual installation was easy. Unfortunately, as I already have a programmer for my central heating system, I do not use the additional features of this thermostat

4/ 5

Pros: Easy to intall and use. Large display. ECO button

Cons: Would be better if it had a backlight on the display.

Purchased as a replacement for old mechanical 4 wire thermostat. Has now been working for approx 4 months with no problems. I was concerned about other reviews regarding noisy relay but you can hardly hear it. The eco button is very usfull if going out for the day.

4/ 5

Pros: The main reason for having this was the accuracy of the settings of the room temp and demand settings,.5 degree increments.excellent

Cons: no real bad points but night time illumination would be a benefit

The buying from the website was efficient. The delivery as promised.The item is fitted and working well.only critisism is slight;it would be better if the item lit up at night

5/ 5

Pros: Easy fit , Looks good , Works well

Cons: Initial set up is fiddly ( but not too challenging), The instructions could be clearer

5/ 5

Pros: It arrived quickly, was easy to fit, easy to set and to understand and is very quiet in operation. It also provides a constant read-out of the ambient temperature.

Cons: The two plastic lugs which need to be unclipped to remove the face of the unit are a bit of nuisance to manipulate without three hands.

This digital thermostat replaces a mechanical version. It is so much more precise in maintaining temperature than the previous stat, which was not that old.

A first class product at a good price.

5/ 5

Pros: Easy fitting - two wires only. Standard wall box or surface fit.

Cons: Fairly loud click each time it switched on or off, and this is quite frequent, even to over-riding the pump over-run timers.

I replaced a standard manual controller with this digital one to improve control of our central heating. Excellent! It was a two wire fit and works really well, holding the rooms at a much more stable temp. than previously. One 'weakness' is the switching noise (clicking) which is much more frequent and quite loud as it hunts about the set temp. more - but this is a small price to pay and if in a hall or outer room would not be a problem at all. The eco feature is brilliant - going out for an hour or two, just touch the eco button and it saves fuel!
