This system gives you the benefits of a variable speed, inverter driven heat pump condenser, combined with a smart air handler with a variable speed blower. This Quick Start Guide covers how to connect the thermostat to your system and ensure proper communication. It is not meant to replace the entire installation manual. Please reference install manual for in depth instructions. ACiQTM Wiring Diagrams and Connections The wiring diagrams below and on the following pages show the proper wiring and DIP switch settings (for indoor and outdoor units) depending upon your application and the type of thermostat used (standard wired controller or 24V thermostat). SCENARIO CONTROLLER SCENARIO 1 (RECOMMENDED) ACIQ COMMUNICATING CONTROLLER (STANDARD) INDOOR UNIT AIR HANDLER CONNECTION BETWEEN INDOOR & OUTDOOR UNITS RS485: S1/S2 OUTDOOR UNIT AHU DIP SWITCH SW1-1 SW1-4 ODU DIP SWITCH S1-2 STANDARD OUTDOOR UNIT OFF (Default) OFF (Default) OFF (Default) SCENARIO 2 ACIQ T755 24V THERMOSTAT AIR HANDLER RS485: S1/S2 STANDARD OUTDOOR UNIT ON OFF (Default) OFF (Default) SCENARIO 3 3RD PARTY 24V THERMOSTAT AIR HANDLER 24V: R/C/B/Y1/Y2/G/W STANDARD OUTDOOR UNIT ON ON ON WARNING In ALL wiring scenarios, be sure to turn off the circuit breaker and pull the disconnect before wiring. Incorrect wiring can cause an electrical short and destroy the main circuits boards! SCENARIO 1: INCLUDED RS485 COMMUNICATING CONTROLLER THERMOSTAT (Standard and Recommended Installation) Please note that using the provided communicating thermostat will provide maximum efficiency. But when using this thermostat the unit will prioritize efficiency over comfort. The system will maintain a comfortable temperature but may run longer than some people desire. For conventional control over the unit see option #2. ACIQ COMMUNICATING CONTROLLER INDOOR AHU OUTDOOR ODU HA / HB* *Interchangeable with optional 20 ft long 4-wire communicating harness. Connects to the S-485 port. NON-POLARITY RS485 COMMUNICATION S1 / S2 18/2 AWG shielded wire must be used & grounded on ONLY one side Gen2 Outdoor Board: Note the cover on BOTH rows of terminal screws. Lift the covers to access the screws. ACiQTM Wiring Diagrams and Connections SCENARIO 1 Continued: INCLUDED RS485 COMMUNICATING CONTROLLER THERMOSTAT (Standard and Recommended Installation) IMPORTANT NOTES Communication wire connected to S1 & S2 MUST be 18/2 AWG shielded cable. Failure to use specified wire can result in communication errors. The shielded ground must be grounded at one end ONLY. DO NOT ground the shield at both ends. Failure to follow this procedure can result in communication errors. Communication wire must be run a minimum of 18" away from any line voltage wires. Failure to follow this procedure can result in communication errors. Always try to run the communication wire perpendicular to power lines and NOT along with them. Ensure battery is inserted in the thermostat and wiring is connected. Without battery, the thermostat will not turn on.

This method prioritizes comfort over efficiency. Please note for this method to work DIP switch SW1-1 needs to be turned ON. This method also uses S1 & S2 to communicate between the air handler and the condenser (no 24 volt wire is run outside) only 18/2 shielded wire is run outside. For additional thermostat wiring options, see page 5. 24v THERMOSTAT ACIQ T755 INDOOR AHU OUTDOOR ODU 24v S1 / S2 NON-POLARITY RS485 COMMUNICATION Verify outdoor unit is receiving 208/240 volts to L1 & L2 as well. L1 & L2 are on a separate terminal block. IMPORTANT! 24 Volts AC must NEVER be connected to S1 & S2. Doing so will cause irreversible damage to the outdoor communication board. Common Wiring Connections, Continued SCENARIO 3: OPTIONAL THIRD-PARTY 24v THERMOSTAT (ECOBEE, NEST, ETC) This option shows how to wire any 24 volt thermostat to the air handler without communication. This method also prioritizes comfort over efficiency. Please note for this method to work DIP switch SW1-1 needs to be turned ON. This method also uses 24v wiring to communicate between the air handler and the condenser using regular thermostat cable. For thermostat wiring options, see page 6. 24v THERMOSTAT INDOOR AHU OUTDOOR ODU 24v XX X X 24v 24V NON-COMMUNICATING IMPORTANT! 24 Volts AC must NEVER be connected to S1 & S2. Doing so will cause irreversible damage to the outdoor communication board. Wiring Diagrams and Connections Without Communication Scenario 3 24v Connection Method C (36k to 60k Units Only): The following wiring diagrams are suitable for the AHU and outdoor condenser when used ith a 24v thermostat without communication. NOTE: This equipment uses B functionality. The terminal is energized for heating functionality. Please ensure thermostat is setup for B functionality.

Only applies if 24 volt thermostat is being used. If using 24 volt thermostat this sets compressor speed instead. ON = slower, OFF = Faster. This DIP switch only works if using the provided communicating ACiQ thermostat. Otherwise delay is time based. Electric Heat Nominal CFM Adjustment SW4 Available settings are 000/001/010/011. Each digit corresponds with an individual switch position. OFF = 0, ON = 1. For example [SW4-1 OFF, SW4-2 ON, SW4 -3 OFF] = 010 S4-1 OFF ON S4-2 OFF ON Heat Settings Cont.

When auxiliary heat is energized the fan will run in Turbo Mode. IMPORTANT: In order for changes to take effect power must be OFF BEFORE DIP switch changes. Default setting is OFF except S4. Please note if using the provided ACiQ thermostat DIP Switch Settings will not need to be adjusted. DIP Switch settings should only be adjusted by a professional HVAC service technician. Please note in this quick start guide the specific DIP Switches that need adjusted will be shown to ensure accurate operation for the chosen set up. For Option 1 nothing needs to be done. For Option 2 please refer to the DIP Switch diagram that shows the correct position of the DIP Switches.Adobe InDesign 19.2 (Macintosh) Adobe PDF Library 17.0
