  If your Daikin Air Conditioner Accessories wired thermostat isn't lighting up, first, check the cable connection between the wired thermostat and the DZK Control Board, ensuring you're not using solid wire. Also, verify the voltage between the poles (A/-) and (B/-) is correct (1.8 Vdc). Note that the zone controlled from the Wired Thermostat cannot be remotely accessed, and after 45 minutes, its dampers will open and remain open until the problem is fixed. If the thermostat is replaced, only perform the initial configuration, as all other parameters and settings will be recovered automatically from the Control Board.

  Error 1 on your Daikin Air Conditioner Accessories wired thermostat indicates a communication error with the DZK Control Board 0B. To troubleshoot, check that this error isn't common to all thermostats. If it is, verify the proper operation of the DZK Control Board, ensuring it's correctly powered and that the expansion bus LEDs are operating properly. Also, verify the polarity of the DZK Control Board and thermostat connectors and check that the voltage between the poles (A/ -) and (B/ -) is correct (1.8 Vdc). Try pressing Reset to restart the device, and if the error persists, press and hold to reset the thermostat. Note that this error may be displayed at the beginning of the process and should disappear after around 30 seconds.

Why does my Daikin DZK030E4-3 unit return to heat mode?

  Samantha SmithAug 30, 2025
  If your Daikin Air Conditioner Accessories thermostat returns to Heat mode when trying to switch to Cool mode, it's likely that the operation mode in the installation is controlled by the Daikin master indoor unit. The operation mode can only be changed from the DZK Main Wired thermostat connected to the Daikin master indoor unit.

  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.
