Rated 5 out of 5 by from Excellent I bought this programmable thermostat to replace a basic digital Honeywell thermostat (DT90e). It was so easy to fit, I could use the same holes as existing. Easy to programme with various features. I am anticipating much better control over my heating and hoping for good savings on my gas bill. I did some research before purchase and decided to go with the same brand, I'm glad I did. I was puzzled by another reviewer who said you need a separate relay box. According to the stat. instructions the switch is rated at 5 amp. My zone valve, which the thermostat controls is 230v, 6 watts so is no problem whatsoever. Bearing in mind my previous stat has been working fine for many years and has a similar rated switch. Perhaps just check the demand of whatever your stat. controls and you'll probably find it will be fine. I don't yet know about reliability but the system insists upon a score. I've scored 5 on the assumption that it will be as reliable as the original thermostat.

Rated 5 out of 5 by from A Big Improvement. I installed this as a replacement for a CM607 and it is much easier to set and program. Installation was particularly easy- it took just a few minutes.

Rated 1 out of 5 by from Disappointing First issue is that the controller was supplied with the European spec which has different firmware to the normal UK version. The installer instructions did not match the unit. Very many emails back and forth with Honeywell and I still do not have a full set of instructions for the European firmware which has limited the functionality of the unit. Second issue is that even with the 'start delay' function enabled it is clicking on and off at the fraction of a degree change. Even the movement of air from just walking past the unit turns it on. Easy to install. Wrong instructions provided and seemingly impossible to obtain them and over sensitive. Would not recommend.

Rated 5 out of 5 by from Does what it says on the 'box Bought this for my Dad, in order to replace an old model that is now obsolete (the T4 programmable thermostat, not my Dad!) Found that it was easy to install, connect and program - met with Dad's approval too Would recommend it without hesitation.

New combi boiler, does this function as timer aswell or do I need separate timer?

I am getting a new combi installed which has no built in mechanical timer. Will this function as the timer and thermostat together, or alongside this do I still need to install mechanical timer? Thanks
Asked by: TevG
All combi boilers require a stat. This will provide both timing and temerature control. I.e it sets the temp for up to 6 periods.

Does this thermostat control heating and hot water separately

Does this thermostat control heating and hot water separately
Asked by: Scamp1000
Only controls heating. Hot water will need control from your original timer which you leave in place and set its heating to constant. This is usually fine as you only need a couple of off/on for water but heating needs several time temps to keep us happy
