JÄSPI Inverter Nordic – An excellent choice JÄSPI Inverter Nordic is an air/water heat pump, specially designed for the Nordic climate, which uses the outdoor air as its energy source. The heat pump is intended for connection to water borne heating systems and can both heat hot water effectively at high outdoor temperatures and give a high output to the heating system at low outdoor temperatures.
2 Installation function An air/water heat pump installation uses the outdoor air to heat up a home. The conversion of the outdoor air’s energy into residential heating occurs in three different circuits. From the outdoor air, (1) , free heat energy is retrieved and transported to the heat pump.

Outdoor air The outdoor air is sucked into the heat pump. The fan then routes the air to the heat pump’s evaporator. Here, the air releases the heating energy to the refrigerant and the air's temperature drops. The cold air is then blown out of the heat pump.
3 Control of JÄSPI Inverter Nordic The heat pump is controlled in various ways, depending on your system. You control the heat pump via your indoor module JÄSPI Theowatti Air or control module JÄSPI_MCU40. See the Installer Manual for the indoor module/control module. During installation, the installation engineer adjusts the necessary settings for the heat pump in the indoor module or control module, so that the heat pump works optimally in your system.
