Rated 5 out of 5 by from Great Product Purchased this to replace an old mechanical controller, I was very impressed with how easy it was to fit and also how quick and easy it was to program.

Rated 4 out of 5 by from Great item but.. This is a great little controller, easy to set up and use, 2 wire control perfect for combi boilers with single link stat input (take the red link out of the terminals marked "room stat" in the boiler and wire up terminals A & B from the T4 stat to these ones, any way round, using 1.5mm 2 core cable) But...two things. 1. Screwfix state "optimization features blah blah" - well yeah on the T4M which they don't sell...the T4 (this item) does NOT have optimization features. 2. They state it's 230v operation....it isn't - it's battery operated but comes with batteries. The 230v rating is actually the output contacts that are rated at 230v / 3A which is enough to fire any boiler with no issues from contact arcing later on...but do NOT use this to run a pump...it needs to control a local relay first or a contactor that is rated to take the pump motor current. If you have a combi boiler (mains fed, does LPHW & CHW independently) then you're fine, the boiler controls the pump itself. Good bit of kit though. Well worth getting.

Rated 5 out of 5 by from Looks Good and easy to use Purchased to replace an older Honeywell programmer. Unit was very easy to fit, the holes lined up with those from the old unit and just 2 wires to change. Unit was fitted and working in just 20 minutes. Programme instructions are simple and the unit looks good and modern. Marked down on reliability as it has not been fitted long enough to judge.

Can it be ued in a wet room?

Asked by: JC48

can this be used to replace a T40 thermostat

Asked by: nonameleftq

Does this thermostat only need batteries in case of mains failure

Does the thermostat only need batteries in case of mains failure or is it actually battery powered and will stop working if the batteries fail.
Asked by: SwissSimon
No, it's battery operated and without batteries it won't work. Takes 2 AA (supplied) which should last a year. Easy to replace

Can the device have 6 temperature settings per day

I have read in the manual that parameter 7 allows you to change the default 4 temperatures per day to 6.
Asked by: FreshAirIan
Yes, The installation leaflet gives the procedure to change the default 4 settings per day to 6, which I have done.
