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.

Delay between 1st stage & 2nd stage electric heat is time based,
not temperature based.
This sets the maximum continuous runtime allowed before the
system automatically stages up capacity. Only applies if 24 volt
thermostat is being used.

Default setting is OFF except S4.
OFF = 0, ON = 1.
For example [SW4-1 OFF, SW4-2 ON, SW4 -3 OFF] = 010
T1 Sensor = Return Air Temp (Room Temp), Ts = Set point
This DIP switch only works if using the provided communicating
ACiQ thermostat. Otherwise delay is time based.
Available settings are 000/001/010/011. Each digit corresponds with an
individual switch position.
If using 24 volt thermostat this sets compressor speed instead.
ON = slower, OFF = Faster.
IMPORTANT: In order for changes to take effect power must be OFF BEFORE DIP switch changes.
