Vaillant Ecotec plus 837 - hot water fine, radiators upstairs fine, wet UFH downstairs not working - S30
Vaillant Ecotec plus 837 - hot water fine, radiators upstairs fine, wet UFH downstairs not working - S30
The UFH is controlled with Heatmiser slimline panels in each room. I have reset all the units but the S30 code still shows when the thermostats are calling for heat.
Hot water is fine and the upstairs radiators (controlled with a wireless Honeywell thermostat) are coming on as normal.
I'm wondering what I can try myself before getting an engineer out.
Any advice please?
