Description of Operation - Package Unit cont.
Cooling, Unit 1st stage
(Single/Dual Capacity Compressor and 5-Speed ECM)
Operation as stated above with separate zone call levels of
YI, Y2, and O being translated into unit call 1st stage (Y1, O).
Blower speed will be the ‘Y1’ setting of the 5-Speed ECM
which is set at the motor.
Cooling, Unit 2nd stage
(Single/Dual Capacity Compressor and Variable Speed ECM)
Operation as stated above with separate zone call levels
of YI, Y2, and O being translated into unit call 2nd stage
(Y1, Y2, O). Blower speed will be the ‘H’ setting of the ECM
which is set up at the heat pump control.
Cooling, Unit 2nd stage
(Single/Dual Capacity Compressor and 5-Speed ECM)
Operation as stated above with separate zone call levels of
YI, Y2, and O being translated into unit call 2nd stage (Y1,
Y2, O). Blower speed will be the ‘Y2’ setting of the 5-Speed
ECM which is set at the motor.
Cooling
(Variable Speed Compressor)
The unit will operate based upon demand as calculated by
the IntelliZone2. The resulting compressor speed, speeds
1-9, (speeds 10-12 are reserved for SuperBoost mode only)
will also select an appropriate blower speed.
Emergency Heat
Emergency heat mode may be engaged by selecting at
the MasterStat. All zone thermostat fault LED's begin to
flash two quick flashes, followed by a pause, indicating
that emergency heat mode has been activated. The
temperature of the structure will be controlled by the
zone 1 MasterStat while other zones are ignored. When
a demand for heat occurs at the MasterStat all zone
dampers are opened and emergency heat is energized.
Emergency heat will continue to operate until the
MasterStat demand is satisfied.
Emergency heat mode may be exited by selecting OFF (or
one of the other mode selections) at the MasterStat, as well
as all zone thermostat fault LED's stop flashing, indicating
emergency heat mode has been deactivated and normal
IntelliZone2 operation may resume.
Continuous Blower
The unit's blower will be operated on blower speed 1
(G-LED) while heating or cooling is suspended for any
zone(s) selected for continuous blower operation at the
zone thermostat. Upon any heating or cooling call to the
unit, all continuous blower operation ceases.
Lockout Mode
(Single/Dual Speed Compressor)
During the unit lockout mode, the appropriate Fault code
will be communicated to the IntelliZone2 MasterStat.
The blower will continue to operate on blower speed 1. If
the collective zones translate into a > 24% heating call,
emergency heat operation will occur and all zone dampers
will open. Blower speed will be Aux Heat speed setting.
Lockout Mode
(Variable Speed Compressor)
During lockout mode the appropriate Fault code will
be communicated to the IntelliZone2 MasterStat. The
blower will continue to operate on blower speed 'G'. If the
collective zones translate into > 40%, all zone dampers will
open and emergency heat operation will occur until the
demand is < 24%.
