1.4 System structure and operation Ground source heating system Ground source heat pump system ver. 1 Principle drawing of a ground source heating system. 1: brine circuit (horizontal ground loop, borehole or lake/pond system); 2: ground source heat pump; 3: heating circuits (radiator heating or floor heating); 4: domestic hot water heating; 5: passive cooling (optional). - Page 9 increases by a few degrees. The brine is then pumped into a heat exchanger inside the heat pump: the evaporator. In the evaporator, thermal energy is transferred from the brine to low-pressure refrigerant, evaporating the refrigerant. In vertical systems, a deep well is bored into the bedrock. In horizontal systems, an extensive coil of plastic pipe (PEM 40/10) is buried to a depth of 1–1.2 meters or more or submerged in a body of water (minimum depth: 3 meters).

Domestic hot water is heated by drawing domestic cold water through a coil inside the storage tank. In tanks with two sections, the domestic water is pre-heated in a coil in the lower section, and brought to its final temperature in the tank’s upper section. Usually, domestic hot water needs to be heated to a higher temperature than the water circulating in the heating circuits. - Page 12 By default, the system supports control of one external supplementary heat source. Control for up to 4 external heat sources is available as an optional accessory. 10 (70) M8011 2204EN...

Limiting domestic hot water temperature In the winter season, the temperature in the lower section of the storage tank is determined by the flow temperature (flow to heating circuits). As outdoor and indoor temperatures are lower, the compressor may run for long periods of time. Consequently, the water in the upper section of the tank can become scalding hot. -

Summer functions ver. 1 1. To activate the summer function, check the Summer Function checkbox. 2. Check the checkboxes for the heating circuit pumps that will not be used in the summer. This will allow you to leave the circulation pumps on where they are needed (in a heating circuit reserved for wet areas, for example). - Page 43 If the system includes an optional room temperature sensor, the system will automatically adjust room temperature to the desired level. If there is no room temperature sensor, the system will always run at full capacity. Free cooling is an energy-efficient and economical method for cooling spaces, since electricity is required only for running the circulation pump and cooling unit fans.
- Page 44 In normal operation, the system will keep the temperature in the brine used for cooling one degree above the dew point. The purpose of this function is to prevent condensate from accumulating in any cooling units connected. ● To disable this function, check the Manual checkbox and enter a specific brine temperature value.
