Radiator thermostats HmIP-eTRV-C-2 and "Valve Position" ? - SOLVED

Beitrag von omicronCZ » 24.04.2021, 16:25

I installed 2 new radiator thermostats HmIP-eTRV-C-2 in one room. It is a replacement for damaged HM-CC-RT-DN, and since HMiPs are already new, I also changed the wall thermostat to HMIP-WTH-2.

But I have some problems:

I control the boiler based on information about open radiator thermostats in the WebUI program.
In the new HmIP-eTRV-C-2 I am missing the value "Valve Position" (channel 4), there is only "Valve Opening" (channel 1), where I cannot set the valve opening rate in percent. And can be set to max. 1.01 (?!)

The value (data point?) "Valve Position" is available for all older radiator thermostats or valve actuators, eg HM-CC-RT-DN or HM-CC-VD.

Would anyone help please?

No one helped here, so I asked for help directly from eQ-3 support, here is the solution.

"...The value Valve Opening corresponds 0.00 = 0% and 1.00 = 100%..."

That it didn't occur to me :-)
