Product Usage Instructions

Option 1 – Connecting the 24 Volt ACiQ Thermostat (Model  T755)
Recommended Option:
This option demonstrates how to wire the 24-volt ACiQ thermostat to the air handler. To ensure proper function, DIP switch SW1-1 must be turned ON. This method utilizes S1 & S2 for communication between the air handler and the condenser, eliminating the need for a 24-volt wire to run outside.

IMPORTANT INSTALL INFORMATION

• Never connect 24 Volts AC to S1 & S2 to avoid damage to the outdoor communication board.
• Verify outdoor unit is receiving 208/240 volts to L1 & L2.

FAQ:
Can I use any 24-volt thermostat with the ACiQ system?
Yes, you can use any 24-volt thermostat with the system. Just ensure to follow the wiring instructions provided for proper communication.

Thank you for purchasing a Next Gen Heat Pump system from ACiQ. 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.

Option 1 – Connecting the 24 Volt ACiQ Thermostat

(Model T755)
Recommended Option

This option shows how to wire the 24 volt ACiQ thermostat to the air handler. Please note for this method to work DIP switch SW1-1 needs to be turned ON. This method 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. (See next page for more details).

Thermostat Wiring Diagram
3H and 2C – With Auxiliary Heat

IMPORTANT INSTALL INFORMATION

24 Volts AC must NEVER be connected to S1 & S2. Doing so will cause irreversible damage to the outdoor communication board.

S1 & S2 terminals are on top. R & C terminals are on the bottom.

To address this issue moving forward the new cover will look as shown below. If you have the old version use the picture below for a reference.

Option 2 – Connecting a 3rd Party 24 Volt Thermostat With Communication

Wire Connected

Any 24 volt thermostat can be selected. Select the appropriate profile from the options listed below to wire thermostat to air handler. S1 & S2 must be connected at the indoor unit and the outdoor unit. Set the system dip switches as shown below.

Option 3 – Wiring Diagram When Using Provided Communicating Thermostat

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 #1.

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 drain wire must be grounded at one end ONLY and the shield foul and conductor MUST be trimmed back and insulated at the other end. 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.

Air Handler DIP Switch Guide

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.
