Switching If the averaged valve position falls below a certain level,
the heat request is set invalid. (Factory setting).
Valve position temperature request On/Off
If ”Temperature request winter operation“ is set to “Switching“, the central
apartment unit checks the averaged valve position of the respective room group.
If the averaged valve position is above the value set for “Valve position temp
request On“ (1..30%), the heat request to heat generation is forwarded.
If the averaged valve position lies below the value set for “Valve position temp
request Off“ (1..30%), the heat request to heat generation is suppressed.
To avoid frequent switching, set “Valve pos req On“ to at least 2%
above ”Valve pos req Off“.
