ITC-308 wifi starting cooling cycle too early

Hello everyone,
I have set 26.5 degree celcius as required temperature and cooling difference is 1.0 degree celcius but cooling start as soon as it hit 26.5 or above. Shouldn’t it wait until 27.5 or above?
Thanks in advance.

Please understand that ITC-308-WIFI has a special temperature mode. Please let ITC-308-WIFI run for 2-3 cycles after the setup is completed. During this period, please do not perform any operations.
