If the compressor on your Honeywell Remote Control isn’t turning on and the “Y” LED is blinking, it's likely due to a 5-minute compressor lockout after a power cycle. Please wait 5 minutes; the compressor will automatically turn on after this safety timeout.
Why is the connected LED on my Honeywell ERM5220R Remote Control red?
If the connected LED on your Honeywell Remote Control is red, it indicates a loss of communication with the system. Verify that the thermostat and/or Equipment Interface Module are powered and functioning correctly.
