INSTALLATION INSTRUCTIONS
6.If an Energy Management System - EMS (load shed) is to be used with the control, two wires must be routed to the electrical control box. The signal required for this function is a normally open relay contact. When the EMS calls for the com- pressor to shut off, the relay contacts should close. Make sure that at least 15" of the EMS wires extend into the electrical box.
7.In the event that other units are to be installed (additional zones), an additional
3.5SYSTEM CONFIGURATION & CHECK OUT
Now that the system is installed, it is necessary to config- ure the electronics, and then check all operations. If the installation is a single zone, (Without a Furnace) no adjust- ment to the dip switches are necessary: however, the stage dip switch is preset to the "ON" position.
3.5.1ELECTRONIC CONTROL CONFIGURATION
A.If there is more than one zone, the dip switch for each successive zone must be set to "ON". To gain access to the dip switches the cover on the unit's electrical box must be removed.
B.Turn "ON" the "ZONE" dip switch on the electronic control board to set its zone. See figure 3.7.

NOTE: The Control Board should have the Stage Dip Switch preset to "ON". All other dip switches are shipped from the factory in the "OFF" position.
C.Turning "ON" of zone 2 dip switch identifies this as zone 2: likewise zone 3 and 4.
D.Stage dip switch is to be in the "ON" position. This will control the operation of the second compressor, provided AC power is available to Circuit #2. The tem- perature differential between the first and second stage is preset and cannot be changed.
E.Turn "ON" the furnace dip switch when a furnace is connected to the blue wires off the control board.
F.Differential dip switch is the difference between the "ON/OFF" cycle of the thermostat. The normal dif- ferential is preset in the circuit board with the dip switchset to the "OFF" positions. In some situations, it may be necessary to decrease the Differential.
The location of the Comfort Control CenterTM may create a condition where the normal differential will not maintain the temperature at your comfort level. If this occurs, the Differential can be shortened by plac- ing the Differential dip switch to the "ON" position.
G.The "GEN START" dip switch - leave in the "OFF" position.
3.5.2SYSTEM RESET
On new installation the COMFORT CONTROL CENTER TM, and/or any changes made to the dip switches requires the electronic control kit to be reset.
A.Turn "ON/OFF" switch to the "OFF" position.
B.Simultaneously depress and hold the "MODE" and "ZONE"
3.5.3System Checkout
A.Verify that all features of the installed system work. Check fan speeds, cooling mode, furnace (if con- nected) and heat pump. If the features do not work, check all wiring and confirm that the correct options have been selected on the Electronic Control Box.
3.5.4Service And Disposal Of Unit
A.The Clean Air Act of 1990 set guidelines in regards to recapturing or disposition of refrigerants. Service agents working with reclamation of refrigerants must be certified by the Environmental Protection Agency (EPA). Check with the EPA authorities for proper han- dling or evacuation of refrigerants.
