Note
The program ramp rate is designed to
reduce the heatup rate or cooling rate
that the furnace normally exhibits.
When not using this feature, the fur-
nace will operate at its maximum
heating and cooling capability.
Note
When the program ramp has ended
or has been reset, the furnace will
continue to maintain setpoint temper-
ature. It will not cool to ambient tem-
perature unless the setpoint is set to
ambient temperature by the program
or by the operator.
