Cap Threshold Adding (
Z.PLU) — This parameter is used in
the calculation of SMZ and is calculated as follows:
Z.PLU = Configuration
COOL
Z.GN * (10 + (4*
(–ADD.R))) * 0.6.
High Temp Cap Override (
H.TMP) — If stages of mechani-
cal cooling are on and the error is greater than twice Y.PLU,
and the rate of change of error is greater than 0.5F, then a
stage of mechanical cooling will be added every 30 seconds.
This override is intended to react to situations where the load
rapidly increases.
