Troubleshooting
The unit is equipped with a receiver that has a digital
display that provides an error code.
• Refer to the table below 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.
1. Make note of the code (E1, EE, etc.), then reset the
display by pressing the ON/OFF button on the unit
controller.
2. Press the ON/OFF button a second time to reapply
power to unit.
3. If the code is still displayed, disconnect and restore
power at the unit disconnect switch or circuit breaker.
4. If the problem was temporary, the code will not reap-
pear.
5. If the error code reappears after power has been bro-
ken and restored at the disconnect switch or circuit
breaker, call VRF Technical Support 1-844-438-8731.
