Tips & Tricks

Leave the Roadrunner Comfort (RRC) ON and it will ramp up as the morning warms and wind down as the evening cools.

The fan will sometimes turn ON or OFF for just a minute or two in the morning or evening (and at night if it’s been hot).  This is normal. When the outdoor temperature is warmer than indoors, the fan will run nearly continuously.

Once a minute, this message appears while RRC  reads the temperature from the sensor at the vent. While this shows, touches are ignored (sorry).

Sometimes the RRC needs a reset to keep working properly. The RESET button is on the side of the wall unit. It’s always OK to reset RRC, it remembers ALL settings and restarts promptly.

The sensor clipped to the vent uses a battery that will last many years. When it needs changing (but with time left to get a replacement), a message will appear on the cooler display. When the battery is on the verge of failing, the message will be flashing and the controller will beep once a minute.
