Stages and can be used to control heating
units. If only one heating stage is enabled,
stage # will then be assigned for this purpose
(refer to the stage combination table in the

average room temperature gets lower than
the stage's start temperature; likewise, the
heating stage stops when the room tem-
perature gets higher than the stage's stop
temperature.
