  If no air is supplied to the grille(s) when activating a zone on your Daikin Air Conditioner Accessories unit, even with the fan coil on, check the following: 1. Verify that the damper assigned to the thermostat is not blocked by the insulation stopper. 2. Ensure the motor is electrically connected properly. 3. Confirm that when demand is created from the thermostat, there are 12VDC between the appropriate contacts for about 5 seconds. 4. Verify that the zone assigned to the thermostat is the correct one; if not, reset and reassign the thermostats to the correct zones.

  mark17Aug 28, 2025
  If one or more zones do not control the temperature on your Daikin Air Conditioner Accessories, verify that the User mode is not set to Stop. Check the room and set point temperatures in the non-working zone thermostat to see if it is creating demand. Ensure that the damper actuator is connected properly. Also, verify that the LEDs D5 and D6 located in the DZK Interface Board mounted over the Control Board are blinking; if not, check the wiring between the DZK Interface Board and the Indoor Unit.

What to do if a Daikin DZK030E4-3 zone is not listed when accessing remote zones?
- S
  Sergio GarciaSep 7, 2025
  If a zone is not listed when accessing remote zones on your Daikin Air Conditioner Accessories, verify that the thermostat of the missing zone is working correctly by activating/deactivating the zone and checking that the damper opens/closes correctly. Note that for zones controlled by Wireless or Wireless Lite Thermostats, it can take up to 4 minutes after a power supply failure for all zones to be remotely accessible.

What does Error 8 mean on my Daikin DZK030E4-3 wired thermostat?
- R
  russelljillSep 4, 2025
  Error 8 on your Daikin Air Conditioner Accessories wired thermostat indicates that the Wireless Lite Thermostat was not found. Check which Wireless Lite Thermostat is not working properly. Verify the thermostat microswitch corresponds with the zone associated. If not, activate it using the tab with the value needed. Ensure the power supply is adequate by checking the battery and replacing it if necessary.
