Think about to fix the issues found by adapter checker

[ioBrokerChecker]

I am an automatic service that looks for possible errors in ioBroker and creates an issue for it. The link below leads directly to the test:

https://adapter-check.iobroker.in/?q=https://raw.githubusercontent.com/Apollon77/ioBroker.daikin

Thanks, your automatic adapter checker.
