INTELLIZONE2 INSTALLATION MANUAL
IntelliZone2 Operation
Upon a call (or calls) from the zones, the IntelliZone2
“weighs” each zone based upon two components: 1) the
level of call (Y1, Y2, Y3) coming from the zone; and 2)
the size of the zone (zone % selected). This gives a very
accurate picture of not only overall heating or cooling
requirements (as in other control methods), but also
how much heating or cooling is really required for each
separate zone.
This, in turn, defines how much compressor (1st or 2nd
stage), blower (speeds 2 thru 5), and auxiliary heat should
be engaged for each particular situation. The result is a
system that utilizes lower compressor and blower speeds
more often for improved comfort and energy savings,
while relying upon auxiliary heat less often for more energy
savings than non-zoned systems.
Heating, Unit 1st stage
(Single/Dual Capacity Compressor and Variable Speed ECM)
Operation as stated above with separate zone call levels of
YI, Y2, and W being translated into unit call 1st stage (Y1).
Blower speed will be the ‘L’ setting of the ECM which is set
up at the heat pump control.
Heating, Unit 1st stage
(Single/Dual Capacity Compressor and 5-Speed ECM)
Operation as stated above with separate zone call levels of
YI, Y2, and W being translated into unit call 1st stage (Y1).
Blower speed will be the ‘Y1’ setting of the 5-Speed ECM
which is set at the motor.
Heating, Unit 2nd stage
(Single/Dual Capacity Compressor and Variable Speed ECM)
Operation as stated above with separate zone call levels of
YI, Y2, and W being translated into unit call 2nd stage (Y1,
Y2). Blower speed will be the ‘H’ setting of the ECM which
is set up at the heat pump control.
Heating, Unit 2nd stage
(Single/Dual Capacity Compressor and 5-Speed ECM)
Operation as stated above with separate zone call levels of
YI, Y2, and W being translated into unit call 2nd stage (Y1,
Y2). Blower speed will be the ‘Y2’ setting of the 5-Speed
ECM which is set at the motor.
Heating, Unit 3rd Stage
(Single/Dual Capacity Compressor and Variable Speed ECM)
Operation as stated above with separate zone call levels of
YI, Y2, and W being translated into unit call 3rd stage (Y1,
Y2, W). Blower speed will be the ‘H’ (Premier control) or
‘Aux’ (ABC control) setting of the ECM which is set up at
the heat pump control.
Description of Operation - Package Unit
Heating, Unit 3rd Stage
(Single/Dual Capacity Compressor and 5-Speed ECM)
Operation as stated above with separate zone call levels of
YI, Y2, and W being translated into unit call 3rd stage (Y1,
Y2, W). Blower speed will be the ‘W’ setting of the 5-Speed
ECM which is set at the motor.
Heating
(Variable Speed Compressor)
The unit will operate based upon demand as calculated by
the IntelliZone2. The resulting compressor speed (1-12) will
also select an appropriate blower speed for the selected
compressor speed. Auxiliary heat will be available on
compressor speeds 9-12, depending on the zone inputs.
When auxiliary heat is engaged with compressor speed
9-11, the compressor speed automatically increases to
speed 12 for maximum output.
Cooling, Unit 1st 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 1st stage (Y1, O).
Blower speed will be the ‘L’ setting of the ECM which is set
up at the heat pump control.
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.
