Supco IAQ1040 Fan Cycle Timer

The Fan Cycle Timer accurately cycles HVAC evaporator and furnace fans through low voltage thermostat connections. When there is no call for heating or cooling, the IAQ helps maximize the Indoor Air Quality (IAQ) accessories connected to the system.

  • Button selection for FAN ON cycle time in increments of 10, 20, 30 or 40 minutes per hour
  • LEDs indicate when fan is running or in off-cycle
  • Monitors the FAN ON green wire from the thermostat and runs the selected On/Off cycle as long as the thermostat does not call for heat/cool
  • Provides a delay function when AC shuts off to prevent bringing excessive moisture from water condensation on the AC coil into the room


Size: 2.2" x 2.2" x 1"
Current: 5 Amps AC
