The T4R has 6 time periods per day, each of which can be programmed by the user. The thermostat is smart, it brings the room to temperature, then uses the electronics to hold the temperature within +/- 0.1 deg. (when room thermostats were mechanical this precision was achieved with a mini heater in the thermostat which eliminated the backlash). It can also optimise the start and stop times (eg switch on even earlier on a cold morning) and there is a holiday setting. It takes time and effort to set the programs that suit you, but the override is simple (eg your partner arrives home early and wants to turn the heating up). The T4R was well worth the investment. I used it to replace a Salus programmable remote (half the price of the T4R) but the Salus program times were fixed and the thermostat kept the room temperature +/- 0.4 deg which was useless.

The programmer is perfectly functional (and appears very sensitive to temp changes) but very basic. Lacking a "boost" button or time display showing close of current programme or time on of next programme, both of which can be viewed but only after you search. It would be helpful to have this information on permanent display. It is however simple to use and controls our central heating and hot water without problem.

An excellent controller that has a simple enough interface for all you need...especially like the big OFF switch so you do not have to worry about the summer months. Bought this from plumbbob_07 and it was with me the next day. Perfect!

This was my second purchase for this item, the first one said "Wireless" but soon discovered that it was a "Wired" system. At first thought I could link the new Thermostat to my 7yo receiver but No. Took a photo of the old receiver wiring (Honeywell), turned the electric off and dismantled the old one. Offered up the back of the receiver to the already present holes to see if I needed to make others. They all matched up. Fitted wires and closed it all up. Linked the thermostat as stated in the "Quick" fit leaflet and up and running. Took about half an hour no longer. Very Pleased.

I bought this to replace my old Honeywell CM927/BDR91 system. It was easy to install - the wiring on the relay unit is exactly the same as the BDR91 so was easy. It has a nice clear display. I have found nothing to dislike about it so far.
