Vaillant Ecotec plus 824 hot water no central heating

[turneeuk]

Hi Everyone,

I just had a Vaillant Ecotec plus 824 installed and could not figure out how to turn on the central heating. I followed the manual and nothing happens. I called my builder and he pushed the plus and minus button together and the system came on. However, it went off after 5 minutes and I froze the rest of the weekend. I didn't know that he had pushed both buttons at the same time. It's not in the instructions.

My problem now is that the system doesn't stay on for more than 10 minutes. There is an external thermostat but I don't see how it's working as I've moved it up down between 15 and 30 and nothing happens. There is also a timer clock but that doesn't do anything either. I've tried to override the system by pressing the +/- buttons together and it still only stays on for a short period of time. There are some openings for storage and my loft but these openings are not large.

Does anyone have any ideas about how I can get the boiler to stay on as long as I'd like? I froze last night...

Kind Regards

Ty

Call your gas safe registered installer. Not a builder! He HAS to show you how it works.

What programmer and thermostat do you have?

Boilers should be installed by a gas registered person and notified to Building Control.

With no demand for hot water press the i button and turn the timer on and the room stat up - do you get S.30?

If so the dufus has not wired the boiler up properly

Pressing the + & - keys together is a test sequence, not proof that the boiler is working correctly.

Same problem, any fix?

If your roomstat and timer are calling for heat, check pin 4 for 240V. If it is not there put a link between 3 & 4, does it now fire up and give S1..7?
If still S.30 check that the CH knob is not broken in the off position, you can turn the spindle from insude the control box

Post back later if you are still having problems, as I've got people to upset and will be back around 6

I'm not getting any messages on the boiler. Water works fine.

My drayton digistat is saying it's asking the boiler for heat, however there is no radiator sign on the boiler.

Hi Griggs,

The thermostat is from Honeywell. The timer/programmer is built into the unit. It think that it may be turning off because it quickly warms up to high temperatures such as 60c / 65c.

I don't have a radiator sign on my boiler either!

I have no idea what pin 3 or 4 is... I am getting the S.30 when I hit the i button. Crap! I will call my original builder that is a plumber. Thanks for your help.
