About this deal

All ST9400 models incorporate the Line of Text (LoT) display that gives clear plain English instructions whenever any button or slider is used.

The Honeywell ST6400A Programmer can be used for combi boilers, heating zones or any application where small electric loads need switching. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. This temperature controller is suitable for a variety of heating systems, such as gas, oil, and electric boilers, making it highly versatile and compatible with different household setups.The heating and hot water programmes are completely independent, to allow the system to be operated in the most energy efficient manner possible. All ST9400 models incorporate the Line of Text (LoT™) display that gives clear plain English instructions whenever any button or slider is used. Tightening the 2 x screws underneath was very awkward too, although that was also true of the old unit. Please note that if the item requires testing your refund will take approximately 14 days from receipt at Adlink UK Limited.

So when it started to play up (The pump would come on but the boiler wouldn't trigger) I decided the controller had gone wrong (despite a plumber telling me it was just air in the heating system).Several times recently the programmer has switched from auto to once for heating without any intervention from us. I set my Hot Water and Central Heating to come on for a couple of hours in the morning, and again in the late afternoon, the Hot Water goes off early evening, and the Central Heating turned off late in the evening. It can be used for combi boilers, heating zones or any application where small electric loads need switching.
