Network Limit
The maximum unit capacity can be limited by a network signal.
This function is only enabled if the unit control source is set to
network. The maximum unit capacity stage is based on the
network limit value received from the BAS, and is determined
as shown in the following graph.
NOTE: In order to allow all stages to run, a signal of 100.0%
is required.
Maximum LWT Rate
The maximum rate at which the leaving water temperature
can drop is limited by the Maximum Pull Down Rate set point
when the unit mode is cool. If the rate exceeds this set point,
no more compressors shall be started until the pull down rate
is less than the set point. Running compressors will not be
stopped as a result of exceeding the maximum pull down rate.
