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.

Honeywell DT90E Wired Digital Room Thermostat ReviewsPrevious
Maintains a stable temperature, this is helped by the cycling that can be setup in installation mode. For my old cast iron gas boiler I use the oil boiler cycle settings. Above the set temp the thermostat is fully off so no worries there. Likewise below the set temp the thermostat is fully on. Much better than my previous digital thermostat and the relay click some people complain about isn't that load. Anyway copper pipes make clicks as they expaned with heat. I set the ECO mode to 16 which has a countdown timer that I use while i'm at work, Well recommended!
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!
I have been looking for a digital thermostat to replace my old thermostat which was not accurate. This thermostat was very easy to install and very simple to use. It is very accurate and controls my boiler much better than the old unit. No more huge temperature over runs it keeps the room temperature within .5 of a degree which has reduced my oil consumption. This thermostat meets all the latest build regulations
A great upgrade to our central heating system. The unit was a straight replacement for an old Honeywell mechanical stat. Just a two wire connection using the existing cable and no set up needed for our requirements. The job was done in less than 10 minutes. The house is now kept at a comfortable, even temperature, rather than the highs and lows of the old thermostat.
