DHV Valve Active

[JamesR]

Hi Stokerforum,

We turned the radiators on 2 nights ago, the first night was fine, there was heat coming from them, but last night we noticed there was no warm in the radiators, and the VVB was staying between 25-30oC.

I noticed on the fyr there stands "DHV Valve Active".  I can hear the pump spinning and water inside, but something seems wrong as the Fremløb 89.2 °C, and the fyr turns off after 10 mins saying the VVB is optimum tempreature.

We contacted our local VVS this morning but no reply :/ any advice on what it should be?

Is there enough water in the system ?

Good question, I have just tried "airing" the radiators out, and no water was dripping.  Is this a sign of lack of water, or lack of pumping?

This is not to say, but there must be refilled with water.
