programmer

Hi, new here and not sure where best to post a question about CH (leccy or plumber?) - moderators please move if necessary. Also I don't know the right terms - e.g. how to differentiate between electrical circuit and water circuit except by context? So apologies if my writing is confusing. I...

Turned the heating on for the first time at the weekend and nothing happened. It was fine last winter and the hot water has been turning on and off with the timer fine all summer. I pressed all the buttons I could think off, turned the programmer on and off and fiddled with the thermostat. No...

Hello everyone! Now the cold weather is here & I’ve started using the timer to bring the heating on in the mornings I’ve noticed that the Programer (Honeywell ST9420C) isn’t working properly. It doesn’t turn on/off when in the AUTO pre set times C/H mode. It works correctly in the AUTO pre set...

A question if I may before I dive in. I have an old gravity fed CH system which thanks to members here in the past - works very well. It has a Danfoss Randal 3060 programmer that has died. I have the original installation docs for the programmer - and it shows 7 terminals plus the earth. In the...

Hi, We have a gas boiler for the hot water and heating. According to our plumber, it is an S-Plan system We've noticed that with the programmer (Drayton LP522) set with both HW and CH to off, the radiators are still heating up. We had a similar problem a 2 or 3 years ago and changed the...

Morning all, the time has come to replace my old Honeywell ST699 programmer. I understand that wiring changes will be needed but that the ST9400C is considered the "easiest" replacement. From what I've read, these are not without their own issues! Honeywell also do a THR860SWE TM2 programmer...

Hi, looking for some advice here. After our old Honeywell programmer (st699) broke recently (no LCD display and no control) I replaced with a new Honeywell st6400c dual. I have a live and neutral wire in which I’ve wired to L&an giving power to the programmer. I also have a wire in with a...

Hello, I need help identifying a replacement for a Dimplex PW programmer which controls the electic heaters in my flat. The old programmer had space for 2 zones but only 1 was connected. I believe it controls the heaters using a pilot wire. The Dimplex PW became defective after catching on...

Hi, I've tried to replace my old thermostat which was mechanical and very old Honeywell model, unfortunately after replacing it with Nest Thermostat E with Heat Link heating is always on regardless of what programmer sends to the boiler. I've got Baxi MainEco 28 Combi with Drayton LPIII as a...

Hi, I have a conventional boiler system (Hot water tank in airing cupboard and cold water tank in loft). I currently have a programmer (Timer, override, boost 1 hour etc.) which controls both heating and hot water separately. I believe it is a S-Plan setup. There is NO room thermostat! Im...

About eight months ago I had a new Worcester boiler installed in my house. Just after the installation my heating/water programmer failed so I decided to replace it with the Hive installation . The system works well for between 7 and 14 days and then when our Internet signal drops out , it...

Hi, I'm no plumber but am looking for some advice on an issue with my heating system. I believe it's a gravity fed, vented, single pipe system. (1 v large container in loft, 2nd much smaller to the side, cylinder with pump and 1 three way valve, all rads have a bypass pipe) Been living here...

So, the last time we used the heating was winter/very early part of this year. A Few nights back we put the heating on overnight for the first time as our newborn seemed a little chilly, since having put it on a few nights back the radiators have started coming on every time we switch the hot...

Hello I am wanting to replace my old analogue British Gas boiler timer with a Drayton LP242 2 channel programmer or similar. My problem is I cannot remove the old unit. There is a single screw underneath which I have removed but the face refuses to budge. I do not want to use force as I am...
