In case of an error the internal memories of the air-conditioner
controller KR-454 can be reset by interrupting the air-conditioner
centre's power supply, by pressing the emergency switch module
or by a RESET with the keys of the air-conditioner controller.
RESET is started by simultaneously pressing keys

This measure is necessary in case of electric errors in the air-
conditioner (short-circuit, discharged batteries, etc.)
