FAN Switch
AUTO: The fan control is normally in AUTO mode, meaning that the fan operates automatically with
the HVAC system and the thermostat. When the fan switch is in ON, the fan will run continuously until
switched back to AUTO.
[NOTE: Fan ON function is available in the OFF mode to allow simple ventilating.]
Simple Screen
This display mode limits the amount of information on screen and limits the functions to just the
+/- arrows. To access the limited display “Simple Sceen”, hold down the PROGRAM button for 12
seconds. Hold down the PROGRAM button for 12 seconds to leave the limited display screen.
RESET button
The RESET button re-boots the 3M-30 processor. It does not effect the user
programs that have been stored in permanent memory.
Compressor Protection The 3M-30 has a minimum cycle time of 4 minutes to protect your
compressor in cool and in heat pump (if you have one). The Home screen will show a small clock and
A/C during this time and the compressor will not come on until the 4 minute delay is over.
