This configuration property indicates the air temperature weighting to be used during Day control. The nviAirTemp2 portion is automatically calculated.
nviAirTemp1 measures -25 degrees C and nviAirTemp2 measures -20 degrees C. Required as a regulation parameter is a weighted average consisting of 60% nviAirTemp1 and the rest from nviAirTemp2 (only the nviAirTemp1 share is programmed). This gives the following regulating value
(0.6 x -25 degrees C) + (0.4 x -20 degrees C) = -23 degrees C
