NOTE: It is not mandatory that the above color code be used, but each ABCD connection in the system MUST be wired consis- tently. A separate ABCD Connector comes inside packaging and should be used when connecting to furnace (or fan coil). Ensure connector is inserted properly into circuit board. (See Fig. 10)

CAUTION: ELECTRICAL OPERATION HAZARD Failure to follow this caution may result in equipment damage or improper operation.

Improper wiring of the ABCD connector will cause the Evolution Zone System to operate improperly. Check to make sure all wiring is correct before proceeding with installation or turning on power.

9.Push any excess wire into the wall. Seal hole in wall to prevent any air leaks. Leaks can affect operation.

10.Attach Evolution Zone Control™ to the mounting plastic by lining up the plastic guides on the back of the control with the opening on the mounting plastic and push on.

EQUIPMENT WIRING DIAGRAMS:

See wiring diagrams Fig. 12, 13, and 14 for connecting the Evolution Zone Control and Smart Sensors to the Damper Control Module. More information regarding Damper Control set-up and wiring can be found in Damper Control Module Installation Instructions.

See wiring diagram Fig. 12 which includes a variable-speed indoor communicating furnace or FE fan coil, with a 2-speed Puron™ communicating outdoor unit. No additional OAT (outdoor air temperature) sensor is required because the Evolution Zone Control will use the temperature sensor inside the 2-speed unit.

See wiring diagram Fig. 13 for connecting a variable-speed indoor communicating furnace or FE fan coil with a 1-speed air condi- tioning unit (non-communicating outdoor). An Outdoor Air Tem- perature (OAT) sensor may be installed (but is not required) at the indoor furnace or fan coil OAT terminals. When OAT sensor is applied, the Evolution System will provide enhanced system features and benefits.

See wiring diagram Fig. 14 for connecting an FE fan coil with a 1-speed heat pump (non-communicating outdoor unit). When OAT is applied, the Evolution system will provide enhanced system features and benefits.

NOTE: For other applications not listed, refer to the Network Interface Module (NIM) Installation Instructions.

HUMIDIFIER CONNECTION — A 24vac bypass or fan powered humidifier may be installed.

NOTE: Do Not Use a traditional humidistat to control humidifier operation. If a humidifier is installed, let the Evolution™ Zone Control operate humidifier.

Bypass Humidifiers — A bypass humidifier should be wired directly to the furnace or fan coil HUM and 24vac COM terminals. The Evolution Zone Control will automatically energize the HUM output during a call for humidification.

Fan Powered Humidifiers — Most fan powered humidifiers produce internal 24vac in order to energize upon a switch or contact closure. For this application, a 24vac N.O. Isolation Relay (DPST) MUST be used to prevent mixing the internal humidifier power with the indoor equipment transformer. Applying 24vac
