AC/Heat Rear Module

This backplane supports common commercial AC and heat pump configurations while unlocking deeper diagnostics and smarter control when you want it.

‍

• Up to 2 stages cooling
• Up to 2 stages heating
  (Up to 4 heating stages for heat pump systems)
• Supply air temperature and humidity
• CO₂ sensing
• Leak or drain pan detection
• Damper actuators, two-position or modulating
• Economizer and demand-based ventilation

The backplane can mount behind the touchscreen or remotely near the equipment, connected with as few as four wires.

That means sensors and intelligence go where they belong, without long wire runs, extra conduit, or added labor. You get smarter control and deeper diagnostics without turning a simple upgrade into a major project.
