Fibaro TRVs not opening rad valves

[h2009 0]

Hello 

 

Wondering if someone can help me please. I've setup my zoned heating in HC2 heating panel and all my TRVs have external sensors which are reporting the temperatures correctly; however the issue I'm having is that the TRV's aren't opening the valves enough to allow the water to pass through the valves and hense there is no heating. 

 

Can anyone suggest a fix for this - noting that I've got 22 TRVs to do this on. 

 

A manual method is to turn the TRVs to max which allows the water to pass through. 

 

Its worth noting that I was using Call For Heat Scene script by Dave Harrison however it was only running through the script once then never again.

Doing this on my phone after a short night, so sorry in advance. 

I have opentherm thermostat in the living room that is the big boss of the heating. 

So if I am thinking right: without the extra temp sensors for the fgt001 and no relay switch on the kettle the heating panel is of no use for me?

Firstly and most importantly, you are aware FGT-001 has bugs so it might not work for you at all? So changing anything right now might be pointless. If you cannot trust your TRV then it kind of ends here, does it not?

 

I am giving you a totally different advice...

 

Do you have a TRV in the living room? And do you have TRV on all radiators? Then use the heating panel. Then set your room thermostat to 25 °C and monitor what happens.
