If you need high temperatures for hygienic DHW generation or for providing heat to radiator systems, the Vitocal 350-G Pro large heat pump is the right choice for you. With flow temperatures of up to 73 degrees Celsius, the pump enables large residential complexes, administration buildings, commercial buildings and communal facilities to be heated in an economical manner. The new Vitotronic SPS (type 2.0) programmable logic controller now makes operation and maintenance even easier – any time and from anywhere.
The new PLC-based Vitotronic makes it really easy to access your heat pump system quickly from any location, allowing you to optimize settings or rectify faults. The control unit boasts a wide range of communication options to aid system monitoring and remote maintenance. Apart from LAN-based systems, you can also use Modbus and Bacnet interfaces, which enable the heat pump to be integrated into a superordinate building management system. Up to four mixed heating or cooling circuits can be monitored and controlled. The system also includes an integrated control unit specifically for cooling operation which permits cold water levels to be regulated by means of waste heat management using geothermal probes or heat exchangers. As an option, the system can be adapted to include the facility to control an oil/gas-fired boiler and a DHW cylinders.
Local operation of the system is very straightforward using the large 7" color touch display attached directly to the heat pump. The heat pump can be operated intuitively without the need to have printed instructions to hand.
The output spectrum of the two or three-stage large heat pump ranges from 27 to 198 kilowatts when using geothermal energy. When using groundwater as a heat source, heat outputs between 37 and 274 kilowatts are available. The heat pump’s high efficiency (COP: 4.4 at B0/W35°C in accordance with EN 14511) is the ideal way of ensuring low power consumption and low energy costs, consistently allowing high flow temperatures to be achieved even at low heat-source temperatures.
The Vitocal 350-G Pro with new PLC-based Vitotronic will be available to order from August 2019.
