9 IGC Alarms

10 IGC Troubleshooting

11 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.

55 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

56 Economizer Plugs Table to help Troubleshoot Economizer wiring at the LVTB and the 12-pin plug

57 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) Same economizer as the R-22 machines.

58 Economizer IV Added occupancy control Low Ambient Lockout
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

59 Economizer IV CO2 Sensor Enthalpy Power Exhaust (PE)
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) DCV – have to work with air balancer to determine the position of the damper and convert to input volts to the actuator. That Vdc is what MIN POS and DCV MAX need to be based on. For IAQ convert the Vdc output to PPM 0-10vdc to PPM, each vdc is 200 ppm.

60 Economizer IV

61 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)

62 Economizer 2 CO2 Sensor Enthalpy (only field installed) PE
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

63 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

64 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
