2 OPERATING SEQUENCE Unit Produced Before /8/0 COOLING, UNITS WITHOUT ECONOMIZER When thermostat calls for cooling, terminals G and Y are energized. The indoor (evaporator) fan contactor (IFC), OFC (outdoor-fan contactor), and compressor contactor no. (C) are energized. Indoor (evaporator) fan motor (IFM), compressor no., and condenser fans start. The outdoor (condenser) fan motors (OFMs) run continuously while unit is cooling. For units with stages of cooling, if the thermostat calls for a second stage of cooling by energizing Y, compressor contactor no. (C) is energized and compressor no. starts. When the thermostat is satisfied, C and C are deenergized and the compressors and OFMs shut off. After a 0-second delay, the IFM shuts off. If the thermostat fan selector switch is in the ON position, the evaporator motor will run continuously. COOLING, UNITS WITH DURABLADE ECONO- MIZER When the outdoor-air temperature is above the outdoor-air thermostat (OAT) setting and the room thermostat calls for cooling, the compressor contactor no. is energized to start compressor no. and outdoor (condenser) fan motors (OFMs). The indoor (evaporator) fan motor (IFM) is energized and the economizer damper moves to the minimum position. Upon a further call for cooling, compressor contactor no. will be energized, starting compressor no.. After the thermostat is satisfied and the IFM is deenergized, the damper moves to the fully closed position. When the outdoor-air temperature is below the OAT setting and the thermostat calls for Y and G, the economizer damper moves to the minimum position when the evaporator fan starts. The first stage of cooling is provided by the economizer. If the supply-air temperature is above 57 F ( C), a switch on the supply-air thermostat is closed between the T terminal and the vac terminal. This causes the damper to continue to modulate open until the supply-air temperature falls below 55 F ( C) or the damper reaches the fully open position. When the supply-air temperature is between 55 F and 5 F ( C and C), the supply-air thermostat has open switches between the T and vac terminals and between the T and vac terminals. This causes the economizer damper to remain in an intermediate open position. If the supply-air temperature falls below 5 F ( C), a switch on the supply-air thermostat is closed between the T terminal and the vac terminal. This causes the damper to modulate closed until the supply-air temperature rises above 55 F ( C) or the damper reaches the minimum position. When the supply-air temperature is between 55 F and 57 F ( C and C), the supply-air thermostat has open switches between the T and vac terminals. This causes the economizer damper to remain in an intermediate open position. If the outdoor air alone cannot satisfy the cooling requirements of the conditioned space, economizer cooling is integrated with mechanical cooling, providing second-stage cooling. Compressor no. and condenser fans will be energized, and the position of the economizer damper will be determined by the supply-air temperature. Compressor no. is locked out. When the second stage of cooling is satisfied, the compressor and OFMs will be deenergized. The damper position will be determined by the supply-air temperature. When the first stage of cooling is satisfied, the IFM shuts off after a 0-second delay. The damper then moves to fully closed position. COOLING, UNITS WITH ECONOMI$ER When the outdoor-air temperature (OAT) is above the ECON SP set point and the room thermostat calls for Stage cooling (R to G + Y), the indoor (evaporator) fan motor (IFM) is energized and the EconoMi$er damper modulates to minimum position. The compressor contactor is energized to start the compressor and outdoor (condenser) fan motor (OFM). After the thermostat is satisfied, the damper modulates to the fully closed position when the IFM is deenergized. When the OAT is below the ECON SP setting and the room thermostat calls for Stage cooling (R to G + Y), the EconoMi$er modulates to the minimum position when the IFM is energized. The EconoMi$er provides Stage of cooling by modulating the return and outdoor air dampers to maintain a 55 F supply air set point. If the supply-air temperature (SAT) is greater than 57 F, the EconoMi$er modulates open, allowing a greater amount of outdoor air to enter the unit. If the SAT drops below 5 F, the outdoor air damper modulates closed to reduce the amount of outdoor air. When the SAT is between 5 and 57 F, the EconoMi$er maintains its position. If outdoor air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the MECH CLG LOCKOUT set point, the EconoMi$er integrates free cooling with mechanical cooling. This is accomplished by the strategies below. NOTE: Compressor has a -minute Minimum On, Minimum Off, and Interstage delay timer.. If Y is energized, and the room thermostat calls for Y (-stage thermostat), compressor no. and OFM are energized. The EconoMi$er damper is maintained at its current position.. If Y is energized for more than 0 minutes, and Y is not energized (whether or not a -stage thermostat is used), compressor no. and OFM are energized. The EconoMi$er damper is maintained at its current position.. If Y is energized, and compressor no. is already energized (see Step ) and the room thermostat calls for Y, the compressor contains to operate. If Y remains energized for more than 0 minutes, compressor no. is energized. NOTE: Compressor no. cannot be energized unless there is a signal for Y from the space thermostat.. If compressor no. is energized, and the Y signal from the thermostat is satisfied, compressors and are deenergized. Reasserting Y will start compressor no. and (after a 0-minute interstage delay) compressor no.. 5. If compressor no. is energized and the thermostat is satisfied, compressor no., the OFM, and IFM are deenergized and the EconoMi$er modulates closed. When the OAT is below the MECH CLG LOCKOUT set point, the compressors remain off. HEATING, UNITS WITHOUT ECONOMIZER When the thermostat calls for heating, terminal W is energized. In order to prevent thermostat short-cycling, the unit is locked into the Heating mode for at least minute when W is energized. The induced-draft motor (IDM) is then energized and the burner ignition sequence begins. The IFM is energized 5 seconds after a flame is ignited. When additional heat is needed, W is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W and W are deenergized, the IFM stops after a 5-second time-off delay. HEATING, UNITS WITH ECONOMIZER/TWO- POSITION DAMPER When the thermostat calls for heating, terminal W is energized. In order to prevent thermostat short-cycling, the unit is locked into the Heating mode for at least minute when W is energized. The induced-draft motor is then energized and the burner ignition sequence begins. The IFM is energized 5 seconds after a flame is ignited and the damper moves to the minimum position. If the two-position damper is used, the outdoor-air damper opens to the minimum position whenever the evaporator fan runs. When additional heat is needed, W is energized and the high-fire solenoid on

3 the main gas valve (MGV) is energized. When the thermostat is satisfied and W and W are deenergized, the IFM stops after a 5-second time-off delay. The economizer damper then moves to the fully-closed position. When using continuous fan, the damper will remain in the minimum position. Units Produced After /7/0 COOLING UNITS WITHOUT ECONOMI$ER When thermostat calls for cooling, terminal G and Y are energized. The indoor-fan contactor (IFC), compressor contactor no. (C) and outdoor-fan contactor (OFC) are energized. Evaporator-fan motor, compressor no., and both condenser fans start. The outdoor-fan motor(s) run continuously while unit is cooling. When the thermostat is satisfied, C and C are deenergized and the compressors and outdoor (condenser) fan motors (OFM) shut off. After a 0-second delay, the indoor (evaporator) fan motor (IFM) shuts off. If the thermostat fan selector switch is in the ON position, the evaporator-fan motor will run continuously. HEATING UNITS WITHOUT ECONOMI$ER When the thermostat calls for heating, terminal W is energized. In order to prevent thermostat short-cycling, the unit is locked into the Heating mode for at least minute when W is energized. The induced-draft motor (IDM) is then energized and the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 5 seconds after a flame is ignited. On units equipped for two stages of heat, when additional heat is needed, W is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W and W are deenergized, the IFM stops after a 5-second time-off delay. COOLING UNITS WITH ECONOMI$ER When free cooling is not available, the compressors will be controlled by the zone thermostat. When free cooling is available, the outdoor-air damper is positioned through the use of a Proportional-Integral (PI) control process to provide a 55 F supply-air temperature into the zone. If the mixed-air temperature is below the lower end of the set point of 50 F, then the outside-air dampers will modulate to minimum position. If the measured temperature is within the 50 to 56 F range, then the outside dampers will hold their current position. If the mixedair temperature is above 56 F, then the outside-air dampers will modulate open until the temperature is within range or they modulate to the fully open position. If outdoor air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the outdoor air mechanical lockout temperature set point (fixed; opens at 5 F, closes at 50 F), the EconoMi$er integrates free cooling with mechanical cooling as follows: Thermostat first stage call for cooling (Y) uses EconoMi$er damper for free cooling. Thermostat second stage call for cooling uses EconoMi$er damper for free cooling, plus compressor no. for mechanical cooling. NOTE: During EconoMi$er operation (damper above minimum position) compressor no. will not operate (sizes 008-0). The high ambient temperature (dry bulb) lockout (fixed): opens at 76 F, closes at 5 F. If the enthalpy of the outside air is too high, the outside air dampers will modulate to minimum position. If mechanical cooling is used with free cooling, the outdoorair damper will be locked into its current position when the compressor starts. If the increase in cooling capacity causes the supply-air temperature to drop below 5 F, then the outdoor-air damper position will be decreased to the minimum position. If the supply temperature continues to fall, the outdoor-air damper will close. If optional power exhaust is installed, as the outdoor-air damper opens and closes, the power exhaust fans will be energized and deenergized. If field-installed accessory CO sensors are connected to the EconoMi$er control, a PI-controlled demand ventilation strategy will begin to operate. As the CO level in the zone increases above the CO set point, the minimum position of the damper will be increased proportionally. As the CO level decreases because of the increase in fresh air, the outdoor-air damper will be proportionally closed. HEATING UNITS WITH ECONOMI$ER When the room temperature calls for heating, terminal W is energized. To prevent thermostat short-cycling, the unit is locked into the Heating mode for at least minute when W is energized. The induceddraft motor is energized and the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 5 seconds after a flame is ignited and the damper moves to the minimum position. On units equipped for two stages of heat, when additional heat is needed, W is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W is deenergized, the IFM stops after a 5-second time-off delay. The economizer damper then moves to the fully closed position. When using continuous fan, the damper will remain in the minimum position. UNITS WITH MOISTUREMI$ER DEHUMIDIFICA- TION PACKAGE When thermostat calls for cooling, terminals G and Y are energized. The indoor (evaporator) fan motor (IFM), compressor (C), and outdoor (condenser) fan motor (OFM) start. The OFM runs continuously while the unit is in cooling. As shipped from the factory, MoistureMi$er dehumidification circuit is always energized. If MoistureMi$er circuit modulation is desired, a field-installed, wall-mounted LC Humidistat or humidistat are required. If the MoistureMi$er humidistat is installed and calls for the MoistureMiser subcooler coil to operate, the humidistat internal switch closes. This energizes and closes the liquid line solenoid valve coil (LLSV) of the MoistureMi$er circuit, forcing the hot liquid refrigerant of the liquid line to enter the subcooler coil. As the hot liquid passes through the subcooler coil, it is exposed to the cold supply airflow coming off from the evaporator coil and the liquid is further cooled to a temperature approaching the evaporator coil leaving-air temperature. The state of the refrigerant leaving the subcooler coil is a highly subcooled liquid refrigerant. The liquid then enters a thermostatic expansion valve (TXV) where the liquid is dropped to a lower pressure. The TXV does not have a pressure drop great enough to change the liquid to a -phase fluid. The TXV can throttle the pressure drop of the liquid refrigerant and maintain proper conditions at the compressor suction valve over a wide range of operating conditions. The liquid then enters a second fixed restrictor expansion device for a second pressure drop to a -phase fluid. The liquid proceeds to the evaporator coil at a temperature lower than normal cooling operation. This lower temperature is what increases the latent capacity of the rooftop. The -phase refrigerant passes through the evaporator and is changed into a vapor. The air passing over the evaporator coil will become colder than during normal operation as a result of the colder refrigerant temperatures. However, as it passes over the subcooler coil, the air will be warmed slightly. As the refrigerant leaves the evaporator, the refrigerant passes a low-pressure switch in the suction line. This lowpressure switch will de-activate the MoistureMi$er package when the suction pressure reaches 60 psig. The low-pressure switch is an added safety device to protect against evaporator coil freeze-up. The low-pressure switch will only de-activate and open the liquid line solenoid valve in the MoistureMi$er circuit. The compressors will continue to run as long as there is a call for cooling, regardless of the position of the low-pressure switch. The solenoid valve and the MoistureMi$er package

4 will be re-activated only when the call for cooling has been satisfied, the low-pressure switch has closed, and a new call for cooling exists. The crankcase heaters on the scroll compressor provide additional protection for the compressor due to the additional refrigerant charge in the subcooler. When the humidistat is satisfied, the humidistat internal switch opens cutting power to and opening the LLSV. The refrigerant is routed back through the evaporator and the subcooler coil is removed from the refrigerant loop. When the thermostat is satisfied, C is deenergized and the compressor and OFM shut off. After a 0-second delay, the IFM shuts off. If the thermostat fan selector switch is in the ON position, the IFM will run continuously.

HT0AH859 FOR 575-V POWER SUPPLY 0V FOR 08/0-V SEPARATE POWER SUPPLY FIELD SUPPLIED FUSED DISCONNECT NOTES:. 575 V transformer No. HT0AH859 is ordered separately from power exhaust.. EconoMi$er actuator and controller are shipped with the EconoMi$er not with power exhaust.. Connections from End Switch plug to the EconoMi$er controller are made by installer.. If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit. Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 8HJD unit with MCA = 8.9 and MOCP = 5, with CRPWREXH00A00 power exhaust. MCA New = 8.9 amps +.6 amps = 0.5 amps If the new MCA does not go over the MOCP published, then MOCP would not change. The MOCP in this example is 5 amps, the MCA New is below 5, therefore the MOCP is OK. If MCA New is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 5 amps per NEC. Fig. 7 EconoMi$er Power Exhaust Wiring 08/0 V and 575 V Units
