Verify that no ERROR number is shown on the screen (see section DZK 

Exception codes, Errors

 and 

section

 Errors in Wired and Wireless Thermostats

). 

17B

The damper-modulating functionality does not work as expected

 

1 

Verify that the damper REG level is located as configured in the 

Type of opening

 parameter (see 

section 

Damper setting

 and section 

System parameters

).  

18B

In Heat mode, when trying to change to Cool mode, the thermostat returns to Heat mode

 

1 

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 Daikin 

master indoor unit. 

19B

In Heat Pump installations, the DZK zoning box connected to a slave indoor unit, 
changes to Stop mode

 

1 

This is caused by the incompatibility between the subordinate unit mode and the master unit. 

Check the master unit is not operating in Fan mode (see User manual). 

20B

Defrost mode on the indoor unit don’t work properly

 

1 

If the Daikin indoor unit has start/stop cycles in periods shorter than 30 minutes, set the dip 

switch #2 in the DZK Interface Board to ON. 

21B

The DZK system does not detect the DZK BACnet Interface 

 

1 

Verify that the LED D9 is blinking and LEDs D7 and D8 are alternately blinking (see section 

DZK 

BACnet Interface auto diagnosis

). 

If the above is not displayed, check the correct connection of the gateway on the DZK Control 

Board, verifying the 4-pin connector. 

22B

The Interface for use in BACnet cannot be connected

 

1 

Verify that LEDs situated on the Ethernet connector

 

(see section 

DZK BACnet Interface auto 

diagnosis

) are blinking, and those in the Ethernet connector are active. If the above is not true, 

check that the Ethernet cable is properly connected 

23B

The indoor unit starts with the system set on off (off or user mode on Stop)

 

1 

Verify that the Setback field setting  on the Daikin indoor  unit is disabled  (see section 

DZK 

Interface Board, Connection and configuration

).
