Daikin MQ616SP furnaces are split into three manifold
sections, partioned as shown in
. Two furnace
control boards are supplied with these furnace models. The
VB1285 control board controls the modulating Section A as
well as the staged section B of the furnace manifold. The
VB1287 control board controls the staged section C. Both the
VB1285 board and the VB1287 require a distinct 0-10VDC
signal as well as a distinct permissive dry contact. These
connections can be made in Terminal Block 2 (TB-2) .Furnace
controls must be operated in tandem to produce the full turn
down.
