Supplemental Compressor Operation during Energy Save Mode – Extends the savings from Energy Saver by
allowing one or two compressors to supplement cooling as needed when Energy Saver cooling is not suffi cient.
Temperature Anticipation – Responds to varying rates of temperature change.
Humidity Anticipation – Modifi es the humidity setpoint to diminish excess humidifi cation and dehumidifi cation.
Dehumidifi cation Mode Lockout – Inhibits dehumidifi cation if not required for system performance.
Start Time Delay – Programmable time delay staggers the start-up of multiple units to prevent high power demand
peaks.
Chilled Water, Energy Saver and Hot Water Coil Flush Cycle – Periodically circulates fl uid in the coil to reduce
deposit buildup in system.
Automatic Compressor Rotation – Periodically rotates the lead/lag sequence to balance compressor run times.
Automatic Reheat Element Rotation – Rotates the staging sequence to balance the run times of the heating elements.
Energy Saver (Glycol) or Auxiliary Chilled Water Operation – Two types of Energy Saver Systems are available.
Programmable Water Under Floor Alarm - Can shut down unit or just compressors.
DIAGNOSTIC AND SERVICE FEATURES
Alarms Displayed in Order of Occurence – Sequence with time of occurrence assist in diagnosing the cause of
alarms.
Programmable Delays for Optional Alarms – Reduces nuisance and false alarms caused by temporary or transient
conditions.
Manual Diagnostic Program – Provides accessible procedures to test the processor and major system components.
Manual Override for Blower, Cool 1 and 2, Heat 1, Humidifi cation and Water Valve – The control circuit is operable
even if the processor is not functioning properly.
Adjustable Alarm Limits – Threshold levels for temperature and humidity alarms are programmable.
Four Programmable Optional Alarms – In addition to the standard alarms, four additional alarms are programmable.
Select Alarms Optionally Disabled – Nonessential alarms can be turned off.
Audio Alarm Tone – Four programmable alarm tones.
PROTECTIVE AND SAFETY FEATURES
Metal Shell Enclosure with Sealed Front Control Panel – Provides electromagnetic interference (EMI) protection and
general protection against environmental contamination and handling damage.
Watch Dog Timer – Automatically resets the circuit board, clears any corrupted memory and restarts the system with
minimal interruption in case of an unfi ltered transient signal.
Opto-Signal Inputs – Isolates the circuit board from electrical noise or static from contactors, compressors and motors
that can contaminate the power at the circuit board.
