Digital Display
The indoor unit is equipped with a receiver that has a
digital display that provides an error code. Refer to the
table to view the error codes. The error code will replace
the temperature setting displayed on the receiver. If more
than one error has occurred, the codes will alternate so
that all codes are shown.
Troubleshooting
Figure 28. Receiver/Display
Make note of the code (E1, EE, etc.), then reset the
display by pressing the ON/OFF button on the unit
controller. Press the ON/OFF button a second time
to reapply power to unit. If the code is still displayed,
disconnect 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 VRF Technical
Support 1-844-438-8731.
