Error Codes - Lennox VRF V22B Series User Manual

Error Codes

Indoor units are equipped with either a small panel with four LEDs that flash to indicate system errors or a digital display
that provides an error code. Refer to the appropriate table below to view the error codes. If the unit has a digital display, the
error code will replace the temperature setting displayed on the front cover of the indoor unit. If more than one error has
occurred, the codes will alternate so that all codes are shown. Make note of the code (E1, EE, etc.), then reset the display
by pressing the ON/OFF button on the wireless remote controller. Press the ON/OFF button a second time to reapply
power to system. If code is still displayed, discon nect and restore power at the unit disconnect switch or circuit breaker.
If the problem was temporary, the code will not reappear. If the error code reappears after power has been broken and
restored at the disconnect switch or circuit breaker, call a licensed professional HVAC service technician.
