Great customer reviews
The AT-019K and AT-022K are designed for straightforward commercial installation. Both units use a male 25 mm water connection (inlet/outlet), compatible with standard commercial pipework.
The 380–415V / 3-phase / 50Hz power supply requires a licensed electrician for connection. Units should be installed outdoors or in a well-ventilated plant room on a level concrete pad capable of supporting 163 kg (gross weight). Maintain a minimum clearance of 500 mm on all sides for airflow and service access.
The RS485 port on the mainboard connects to your BMS via standard Modbus wiring. For hotel hot water heat pump system design guidance, consult your MEP engineer to size buffer tanks and circulation loops based on peak demand. Commissioning requires setting target water temperature (up to 60°C) via the smart controller panel.
