capacity limit
If the evaporator LWT exceeds 18°C, compressor load shall be limited to a maximum of 75%.
Compressors shall unload to 75% or less if running at greater than 75% load when the LWT exceeds
the limit. This feature is to keep the circuit running within the capacity of the condenser coil. A
dead-band placed below the limit set-point will be used to increase function stability. If the actual
capacity is in the band, unit loading will be inhibited.
