Some HVAC relays needed 24VDC of electric power source. Meaning it demands 24V of direct existing energy. In the event the incoming ability provide is 240VAC (240V alternating existing), then a 240VAC to 24VDC transformer is required for the facility conversion.
ACU means Air Conditioning Device. ACU is usually a generic term applied to point an air con device, whatever the type. The air conditioning device can be AHU, FCU or every other form of air conditioners that gives airflow and air con to the place.
