A ground source heat pump can extract geothermal heat from soil, water system or a bore hole. The ground source heat pump unit consists of an integrated hot water storage tank, compressor unit, heat exchangers, closed refrigerant circuit and controlling system. The heat collection fluid in the ground circuit, the refrigerant and the water in the heating network never mix at any stage of the process. Heat is transferred between fluids using plate heat exchangers. More specific technical details can be found from Vsi 6-14 manual: https://www.lampoassa.fi/en/products/brochures/

The ÄssäControl control system developed and manufactured by Lämpöässä is used in Vsi units by default. It allows controlling the operation of the entire geothermal energy system as concerns heating, hot domestic water production, and cooling alike. Thanks to touch screen and function shortcuts it is very easy to use ÄssäControl. The control system collects history data and analysis of this data allows more efficient and economical control over the entire system. There is also optional remote control available for ÄssäControl (WLAN, GPRS, fixed network), which enables remote monitoring of the system.

Additional accessories available for Vsi-model pumps:

Control system for multiple heating circuits

The standard package of a Lämpöässä geothermal heat pump includes a control system for one heating circuit. A control system for two or three heating circuits is also available, enabling different areas within the household to receive heating water of different temperatures. For instance, one temperature for floor heating and the other for a radiator network, or one temperature for the humid rooms and the other for the rest of the household.

Delivery package for two heating circuits includes in addition to standard delivery also pre-installed control system application, valve actuator, the actuator mounting kit, three-way valve, A-energy class heating circuit pump and flow sensor.

Remote access of ÄssäControl

The heat pump unit’s remote access allows the user to monitor and control the operation of the geothermal heat system via the Internet with e.g. a tablet or a smart phone. Remote access is possible in many different ways: via a wired cable web connection, via a WLAN modem or 3G. In addition, ÄssäControl is available with a remote alarm function in case of possible disturbances.

ÄssäControl DPV room sensor

The room temperature sensor measures the current room temperature, according to which it adjusts the temperature in the direction of the desired set temperature, keeping the room temperature nicely even.
