Rail heat settings in the AK-CC550
o85 = Rail heat control (select option 2, pulse control with dew
point function)
o86 = Dew Point MIN limit
o87 = Dew point Max limit
At a dew point which is equal to or lower than the value in 086, the
eect will be the value indicated in o88. In the area between the
two dew point values the controller will manage the power to the
rail heat
For adaptive rail heat to function correctly ensure the AK-CC 550
controllers are set correctly. Review parameters o85, o86 and
o87, as noted below. The screen image below highlights the AK-
CC 550 controller (Miscellanious menu), where parameter o85,
o86 and o87 are set for rail heat control over the bus.
