Heizkreise setup

[marvinek]

Hi Tbi,

at this moment I have it connected as you propose in 1. Only most important (or where there is probability for higher temperature request) valves I have linked to the HK. I was looking for more elegant solution but buying new equipment only for this I don't see as wise decision. If I buy something what allows to create this logic I will change the setup for sure.

Hi Marvin

you can't configure more than 8 in the FM446. You have two posibillities:

1. Only connect the "most importend" valves
2. Do you own average calculation by HS or equivalent and connect this result to only one valve.( as Nils already told)

There is also the way to configure a mixed mode EIB and normal. In that case the FM446 reduse only the requested heat and didn't stop. I would not do so. You find the calculation in the service manual.

Best Regards


Tbi

hi,

is there any other way how to manage it if I don't have any logic module?

Hi just group them together with some kind of Logik and send the maximum value.

for example with the HS:
you would group all Sleepingrooms "Stellwert" together with "Maximal-Wert vergleichend"

Hallo,

I have Buderus FM446 module where you can link to 1 Heizkreis up to 8 independent Ventistellungen (thermoantrieb). The question is: How can setup the FM446 if I have more than 8 independent Ventistellungen (radiators in more than 8 rooms)?

Thanks for your help
