SCR Control Type—Sets the control type for the SCR reheats. If set to “Standard,” then the reheats
will modulate when the temperature is below setpoint based on the control settings. If this parameter
is set to “Tight” control then one compressor will be locked on and the reheats will modulate to offset
the cooling capacity.
Start Compressor 1 / 2 at—Sets the activation point of the compressor. This parameter can be used
when set to “Tight” control.
Stop Compressor 1 / 2 at—Sets the deactivation point of the compressor. This parameter can be
used when set to “Tight” control.
Compressor 1 / 2 stop delay—Sets the delay when the stop compressor setpoint is met.
