Hi I have recently had a Vaillant Ecotec 837 combi installed but I am not sure if it is working correct - Can someone advise.
Hot water works fine no probs there.
The boiler has a Outdoor sensor for weather compensation installed - My installer had never fitted one before so he is unsure if system is working correctly or not.
The heating works but seems to keep cutting out before it reachs the temperature set on the VRC430 controller.
For example tonight I had the system on Auto and set the temputure to 25c and the room temp was 20c and outside was 15c
The sytsem came on s.4 was shown on the bolier, however when room temp got to 22c the system shut off.
s.7 was displayed on the boiler (pump over run)
next it went to s.8 (antic cycling mode) what ever that is??
There is also a flashing radiator on the bolier display (I am sure this is relevant but there is no mention in the manual)
After a perioed of time the boiler will reignite and go back to s4 but it seems to stop shortly after.
Checking the pressure of the boiler at the time it shuts off it is around 1.9 bar (which I would not think is the problem)
Is this working as it is supposed to or is there a fault?
what does the flashing radiator mean?
The boiler has been installed but plumber is on holiday and I have not been able to fill in waranty card as have no corgi number.
Please help
Rory
