Using remote control "on" the unit, then push the C button of remote control, if the C display at the unit "off" the unit using also the remote control. Unplug the power supply then plug again and start the unit using the remote control.
It the instruction above don't solve the problem, the return air sensor is out of range or the main board of the unit itself is defective. You need a qualified tech with this problem.

SOURCE: WRAC has E4 on display

E4 means return air sensor error, if the error cannot reset may be the return air sensor is out of range or defective. But if the sensor is ok you need to replace the control board itself. The reading of return air sensor is 8k to 10k ohms @ 25deg. C temperature.

SOURCE: Error code of E4 on Dometic HP air conditioner ??

16. SYSTEM RESET
a. Turn the ON/OFF switch to “OFF” position.
b. Simultaneously depress and hold the MODE and ZONE
push-buttons while turning the ON/OFF switch to “ON”.
FF should appear in the LCD display until the MODE
and ZONE push-buttons are released.
c. When a dip switch is turned on or off after initial configu
ration, a system reset will need to be done before the
Comfort Control CenterTM will recognize the updated selection. Try this. This is for the five button thermostat. Did you check the dip switches to be sure the proper ones are turned on? I need to know which stat you have 4 or 5 button. I have trouble shooting for both.
If you notice reset needs to take place after a dip switch is turned on or off. The dip switches are on the circuit board. You need to drop the lower cover. the dip switches will read in this order #1 heat strip/ #2 zone2/#3zone3/ #4 zone4/#5 furnace/#6 differential/#7stag/#8 gen start. Check this out and be careful. Turn off the stat to change dip switches. On will be toward the description. If you don't have remote start gen set the dip should not be on. If you dont have a Zone 3 the dip should not be on, etc.
Any questions feel free to post back
Thank you for using fixya
