Typical.. search for about 30 minutes. No luck. Second I post this, I find the procedure on YouTube of all places! Re-sync worked. Happy chappy.

Hi Guys, Got a CM927 that I installed a few years ago. It's been running fine, until the other day. I noticed a red flashing LED on the relay box. I've looked it up and it seems to indicate loss of connection with the room thermostat. I've placed the thermostat next to the relay, but it's...

Hi Guys, Got a Heatslave 15/19 Oil boiler. This morning we woke to no hot water. Checking the boiler I find a fuse has blown and tripped the MCB. Change the fuse, turn it on and away we go... except it then locks out. I press the reset button on the TR830.2 and get an almighty ban from...

Hi Guys, Got a Heatslave 20/25 Oil boiler. I'm having problems with the amount of DHW available. It appears that once the tank is empty, the boiler is unable to provide enough for hot water for the demand of a shower. Any ideas on where or what to check? We are becoming fed up with 3...

Hi All, Many thanks for all the excellent replies! I think I've got a good idea on what I need to do now.. my only other thing would be HOW to install an access point. Is there such a thing as a rod access point, but at 90deg rather than 45? That would be perfect!

LOL, no idea.. chucked em now. I bought them from B&Q though.. combined chimney and plumbing rods.

HI there, Thanks for the reply. Unfortunately they broke. First time it broke just below the connector. I then put another rod down with a hook, and that broke too! No tight bends or anything.. just crappy crappy rods :( Obviously I really don't want to put anymore down there!

Hi Guys, Recently bought a new home, and 6 months in have come across a problem. The property comes with an Annex (that my elderly mum lives in) and the annex drains keep blocking. We had it pressure cleared a couple of times, then when it blocked the third time I thought I would save...

Sorry for the delay in getting bacl.. I have been 'observing' :D OK, so the 927 was and is set to off, so it's not running a program at all. So that would rule out a program turning it on. The 927 works fine when used normally, it does indeed turn the indicator light on on the relay when it...

Hi Everyone, Looking for some help please. I have a Heatslave 15/19 Oil boiler. When we came here it had just a Honeywell ST699 controller (no room thermostat). We wanted to add some more control over the system, so I purchased a Honeywell CM927. I wired it with Live & Neutral from the...

Hi John, Many thanks for the confirmation! I thought it would be the case, but never quite sure :) Many thanks! Marc

Hi Guys, Just bought a new house that has a Heatslave 15/19 installed (oil burner). The programmer that is connected to it as a couple of settings for DHW which are Off, Cont, Twice, Once. Now I understand what they all do, but not sure if it's ok to leave it on continuous? When I DO...

[/url] Oh nice, thanks !!

Excellent, thanks !! Well it's kinda complicated, but at the moment our system is not working very efficiently. We are going to get it powerflushed to clear a blockage but can't afford it for a month or so. This means that to get the system to 21c at 7.30am the damn thing is coming on at...

Hey Guys, I've got a Honeywell CM67 Wireless thermostat connected to my system. It's not really a big issue but I think one of this thermostat's features in annoying me. I believe the thermostat has a facility so that if you set it to be at 21c at 7.30am, it will start heating up the...
