Atlanta Series Geothermal HVAC Control Board
P/N 236-802

The Atlanta series control board is a microprocessor based four zone multi-compressor geothermal HVAC control board. The Atlanta series control boards represent a quantum leap in residential and commercial HVAC controllers for the 21st century. Dozens of features, many of which are unique, make the Atlanta series geothermal HVAC controller the perfect, high tech choice for your next generation geothermal HVAC and in-floor heat pumps. Here are just a small group of highlights which set the Georgia Controls Atlanta series control board apart from the rest:


  • 1 to 4 zones with damper control
  • 1, 2, or 3 stages
  • 1 or 2 compressors (including 2 stage 1 compressor systems)
  • Connectors organized by function
  • System status LEDs on board
  • Diagnostic LEDs on board
  • Dual microcontroller motherboard
  • 4 key keyboard
  • Inputs protected and optically isolated
  • Efficient, cool running switch mode power supplies
  • Regulated voltage ensures relays stay latched without overheating
  • 3 built in fan drive types supporting single, multi, and variable speed blowers
  • Heat strip output for emergency use and selectable as extra heating stage
  • 4 programmable, auxiliary function relays
  • Low, medium, and high freon pressure inputs alert the processor
  • High pressure cut out is physical as well as being processor controlled
  • DripCopDripCop TM automatic shutdown condensate monitoring system
  • Fused 24 VAC Input, 50/60 Hz
  • Supports heat pump and conventional type thermostats, with or without snubber circuits
  • Thermostat types can be mixed in a single system
  • Independent G (fan) call inputs
  • Real time clock with battery backup
  • F1, F2, F3, and E relays can be electrically isolated from circuit board
