Thermostat hit and miss with boiler

[Husk24]

hi guys

I have had a new boiler installed, an ideal logic 30k system boiler, with Danfoss rf thermostat RET2000b-rf+rx1-s, wireless. I have had problems with boiler not turning on with thermostat and sometimes not switching off, the installer has now moved the receiver even closer and I am still having problems, the signal sign is showing on thermostat and so is the heat sign. The receiver ch button is on red like it should be but boiler does not come on, today nothing happened for ten minutes so i turned the thermostat to off twice and back up, then it worked.

Any suggestions what the issue might be?

Thanks

I think you'll find this is something in the boiler as I had a similar issue with a vogue combi (Ideal) where it would turn on but not off. They attended under warranty as all equipment was from them and they ended changing something in the boiler although the customer doesn't know what

Hi JVTrades, its only not switched off once or twice but my main issue is it does not seem to come on when I set temperature especially first thing in morning when boiler has been switched off overnight.

could be something interfering with signal. how far away is the room stat? metal stud walls?

 

[Husk24]

The receiver was about 15 meters away, it should work upto 30 meters but there were a few walls in between and now that has been moved and the distance from receiver to thermostat is roughly 3-4 meters with one wall in between. The receiver lights up when i turn thermostat up, its the boiler that doesn’t turn on when it should do

Then it sounds like either there is a fault with the switching from the receiver or the boiler itself. I think you need a sparky to test these things.

Does the boiler not come on quickly in the morning or just not at all even after waiting?

Get the installer back it's not operating correctly. Kop

Its hit and miss, sometimes it comes on within seconds and then likd this morning I waited 5 minutes and nothing happened, then I switched the thermostat down and up again then it came on instantly, it is intermittent. Got boiler installer and electrician coming on Wednesday to check boiler as well as thermostat /receiver.

keep us posted.

Is it 240 or low voltage controls? I'd be checking the sl from the thermostat receiver is sending 240 then checking the boiler terminals are receiving it, could be as simple as a loose wire, or a faulty stat.

Or if the boiler is receiving current but nothing happening then contact Ideal and go the warranty route.

 

[Husk24]

No idea about the voltage myself but the thermostat/receiver was replaced today with a new one, exactly same, said it was working fine until I came home n checked it was doing the same as above hit n miss. The boiler was only installed 4 weeks ago alongside the thermostat. Now the second one is still doing the same.

hum ......... in an empty field.

are you sure the boiler is set to constant?

 

[Husk24]

What do you mean set to constant?

 

[Murdoch]

What do you mean set to constant?

On all the time .... so the room stat turns the boiler on and off

If you have a timer on the boiler or controller, and a time setting on the room stat it’s not a good set up ...

 

[Husk24]

I have a timer which is always set to on all day during daytime and off night time as we don’t have heating on during night. Then I have this Danfoss thermostat which is purely to raise or lower temp, it is not programmable. This issue occurs during day when timer is set to on.

He really does bring a lot to the table mate. Must have a good 30 seconds experience.

Shaun block the troll bud dont need this on here . Kop

Pretty sure this is boiler related. In the Vogue there’s a link that needs to be removed when commissioning that’s easy to miss. Could be something like that that’s interfering with the switching. Talk to Ideal and explain the issue they may help with something like this even if not an installer.

 

[garygvl]

if the hot water is working ok but not the heating its not a boiler problem as common switched live to boiler for both unless youve got weather compensation fitted then seperate switched lives needed

 

[Husk24]

Hot water is fine, it has a separate thermostat for that attached to the water cylinder.

One thing I have noticed it works fine when im away from home or should I say when my car is not parked in garage, apparently they both run on the same frequency, maybe an interference which the thermostat cannot cope. My gas/electric SMART METER goes off/disconnects as soon as I park my car, comes back on when I drive away! When I disable the sensor in my car the smart meter comes on.

I bet you don’t get free gas and electric though, if you do maybe smart meters do have a use.
