My understanding is that temperature is controlled by both: the D2 CPU and the Digimax with their individual sensors. The heating cycling is optimally set by the factory as a tradeoff between constant space temperature, low fuel consumption and maximum components life. The space temperature could vary by 2-3 degree centigrade.
Tighter control of space temperature will decrease maintenance interval requirements and reduce components life.
Problem of using DigiMax to fire the D2 could be related to setting minimum voltage, perhaps decreasing it to 11.4V (vs 12v or 12.2V) could help - http://butlertechnik.com/download/5x/Eberspacher_Digi-Max_D1000_Operating_Instructions.pdf
Good luck,
George.
