80 ● gForce Ultra User Manual 10-2014
Cooling Mode: Only shown up if Supply Temp was selected for Control above, It is
selectable between Normal and Precise. Precise mode allows the reheat to run at the
same time with the compressors to allow more precise temperature control. Do not
select this in gForce Ultra units. It is only applicable for fixed speed compressor units.
Electronic Valve: Single or Dual, depending on how many circuits are in the system.
Electronic Expansion Valve (EEV) provides highest possible efficiency for the refrigerant
circuit at a much wider range of unit operation compared to normal TXV. These valves
are standard for gForce Ultra units to maximize efficiency at different compressor
speed.
HP Lockout: Counts the number of compressor high head pressure alarms to lockout
the compressor. Range is from 2 to 5 times per hour. Default setting is
None
.
Delay btw stages: The delay time between two cooling stages, defaults at 60
seconds, ranges from 30 to 300 seconds.
If the above Control setting was set for “Supply Temp”, the next screen will be as
followed
NOTE:
Any changes in this screen might result in system imbalance, only
change this when if you are familiar with tuning a PID.
