11 IGC Error Codes: From NSMM 2003 (SPP PPT) in HVACPartners Fault 2 – Limit Switch OpenIf limit opens:Gas valve and ignitor will be disableIndoor blower will immediately energized.Inducer shall remain energizedThe 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.

57 Economizer IV Electro-mechanical Unit Economizer Stand alone operation with Honeywell W7212 controller.Compressor control runs through the W7212If no econ then jumpers must be in 12-pin plug for cooling to operateActuator is 2-10 vdc pre-programmed ready for W7212 outputSAT in 12-pin plug (PL6)Same economizer as the R-22 machines.

59 Economizer IV CO2 Sensor Enthalpy Power Exhaust (PE) IAQ install, uses 24Vac (TR & TR1), and 0-10Vdc signal (AQ & AQ1), TR1 & AQ1 are commonDemand 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 damperDCV MAX (POT) tells the controller at what damper position do you want us to stop opening for DCVThe damper will modulate between the MIN POS (POT) and DCV MAX (POT) settings proportional to the IAQ vdc input from DCV SET (POT) to 10VdcEnthalpyThe 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 coolingRemember O for outdoor and R for ReturnEnthalpy sensors are HH57AC078 and Dry bulb are HH57AC074Power 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.
61 Economizer 2 Econ2 No controller, requires Plink or RTU-MP/open Jumper wires in 12-pin plug for cooling operationActuator is 2-10vdc pre-programmed500 ohm resistor (pre-installed) required for 4-20 controller outputOAT in 12-pin plug (PL6)
