Rated 4 out of 5Â by oldsparky65 4th one purchased
Purchased this to replace existing one which have had for nearly 20 years.
Easy to programme and is easy to understand what it does.

Faced with an emergency heating control failure on a Saturday afternoon I was able to quickly research my requirement on the Screwfix website. Found the exact replacement I required in stock at an excellent price less than 5 minuets from home. Job completed in less than an hour, heating back on wife happy. Thanks to Screwfix.

Rated 4 out of 5Â by RamblinPete Like changing a plug!
When I moved in to my house, it had a Centaur C21 central heating controller fitted. This would control hot water and heating every day to the same time schedule. OK if you have a regular lifestyle. I wanted more flexibility, so I eventually got the C27 - each day can be set to different time schedules, so say you have an evening class every Thursday straight after work, you can set the heating to NOT be on when you are out of the house on Thursday evenings! Weekends can be set to have a nice warm lazy sunday morning!
This unit is a direct drop in replacement for the C21 - the most difficult bit is undoing the two small screws underneath to release it. After that, take off the old, put on the new. Simple. If you can unplug the toaster and plug in the kettle, you can change this.

Bought as a direct replacement for the identical existing programmer which failed after three years. Easy to fit, good instructions and good features. Let's hope this one lasts.
