IGC Troubleshooting
IGC Error Codes:
From NSMM 2003 (SPP PPT) in HVACPartners
• Fault 2 – Limit Switch Open
If limit opens:
•
•
•
•
Gas valve and ignitor will be disable
Indoor blower will immediately energized.
Inducer shall remain energized
The indoor blower will turn off after the fan off
delay if “W” goes away.
• If limit closes again the fault will clear. If you
still have “W”, the gas valve still open and
re-igniton will occur.

Economizer Plugs
• Command Center aka Low
Voltage Terminal Board (LVTB)
 ECON 10pin Plug
• Used for all Economizers
 SAT/OAT 4pin Plug
• Used for Econ 2 only
 OCCUPANCY Terminals
• Used for Econ IV and 2-pos Damper
• 12-Pin Plug (male) – Unit Side
plug in Econ Section
 Same plug and arrangement as old
units
• 12-Pin Plug (female) – Econ Side
 Comes with specific FIOP or
Accessory
 Small change on the Econ IV plug
Economizer Plugs
• Table to help Troubleshoot Economizer
wiring at the LVTB and the 12-pin plug
Economizer IV
• Electro-mechanical Unit Economizer
• Stand alone operation with Honeywell
W7212 controller.
• Compressor control runs through the W7212
If no econ then jumpers must be in 12-pin plug
for cooling to operate
• Actuator is 2-10 vdc pre-programmed ready
for W7212 output
• SAT in 12-pin plug (PL6)
Economizer IV
• Added occupancy control
 The “N” terminal tells the controller when occupied
 R-22 units had W7212 main power fed from the IFC and jumper to the N
terminal
 410a units have main power fed from transformer, and IFC feeds the N
terminal trough the Occupancy terminals
 So W7212 is powered up when the unit is, instead of only when the fan
is on
• Low Ambient Lockout
 The “LA” switch is installed on the Y2 input to the controller
 Part number HH18HA286, Contacts Open: 42°F ±5°F, and Contacts
Close: 57°F. ±5°F.
 Below 42°F the second compressor will not run, econ will be stage one
and 1st comp is stage 2
• Power exhaust wire




Tan wire that is connected to 24Vac HOT, move to EF1
Add jumper from 24Vac HOT to EF
Connect other end of the tan wire to the tan wire in the PE Kit harness
Connect the Grey wire in the PE kit harness to the 24Vac COM terminal
Economizer IV
• CO2 Sensor
 IAQ install, uses 24Vac (TR & TR1), and 0-10Vdc signal (AQ & AQ1), TR1 &
AQ1 are common
 Demand Control Ventilation (DCV) is the only CO2 control available for Econ IV.
• DCV SET (POT) tells the controller at what input vdc from the IAQ sensor do we
want to start opening the damper
• DCV MAX (POT) tells the controller at what damper position do you want us to
stop opening for DCV
• The damper will modulate between the MIN POS (POT) and DCV MAX (POT)
settings proportional to the IAQ vdc input from DCV SET (POT) to 10Vdc
• Enthalpy
 The Single Enthalpy sensor uses the same terminals as dry bulb (SO+ & SO).
 For Differential Enthalpy, 2 enthalpy sensors required. One installed per
above and the other on terminals SR+ & SR (after removing the resistor).
Set the cross over POT to “D”
• Whichever is lower is the air used for cooling
• Remember O for outdoor and R for Return
 Enthalpy sensors are HH57AC078 and Dry bulb are HH57AC074
• Power Exhaust (PE)
 Terminals EF and EF1 are dry contacts and switch when the damper pos (in
Vdc) gets above the EXH SET (POT) setting (in vdc)
Economizer IV
Economizer 2
• Econ2
No controller, requires Plink or RTU-MP/open
Jumper wires in 12-pin plug for cooling
operation
Actuator is 2-10vdc pre-programmed
• 500 ohm resistor (pre-installed) required for 4-20
controller output
OAT in 12-pin plug (PL6)
Economizer 2
• CO2 Sensor
 IAQ is installed on the specific controller via PL18 for FIOP and
direct to controller when field installed
 DCV is set in the specific controller with a user interface.
• Enthalpy (only field installed)
 Single or Differential control from the DDC controller
 Uses the 2 loose Grey wires near unit’s 12 pin plug
 Sensor wires run to the LVTB and then to DDC
• PE
 Wires provided with the PE accessory have to be run to the
control box specifically to which ever DDC is installed
 Switch one stage on and off based on damper position
Economizer 2
• Cooling jumpers must be in
harness for cooling to work
• Resistor must be between the
White signal wire and Black
actuator common
 Actuator is 2-10v and
controllers output 4-20mA
• Enthalpy sensor power from
Actuator power
 Switch signal using 2 grey
wires
• When troubleshooting
 Read vdc across resistor
• Determine if it’s the actuator or
the controller
 Shorting the actuator signal to
24VAC will drive it 100%, but
disconnect the actual signal
first
 Spring return Closed
 Direction switch set to same
direction as the spring return
2-Position Damper
• Opens to set position
whenever the fan is running
• To set position, set the screw
on the actuator face near the
shaft opening
Low Ambient
• Winter start Kit (CRWINSTR001A00)
 3 minute timer relay to bypass low pressure switch
