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).
3. Specify the start month for the summer period with the plus and minus buttons.
4. Specify the end month for the summer period with the plus and minus buttons.
5. Specify the minimum temperature at which the summer function will be active by
tapping the
Function min temperature
field.
4.6.5 Magna geo control: brine circuit pump settings
When commissioning the heat pump, the flow rate of the brine circuit pump can be
adjusted.
1. Use the
Brine pump speed
slider to adjust the flow rate as a percentage of the
maximum.
●
At 0%, the pump will be stopped.
●
At 1%, the flow rate will be at its lowest.
●
At 100%, the flow rate will be at its highest.
●
Factory setting: 90%.
The selected percentage value will be shown next to the slider.
4.7 Cooling (optional)
The ground source heating system can be equipped with optional cooling solutions.
Basic cooling options can be accessed through the
Other settings
menu (menu button
→Other settings →Cooling). Advanced cooling options can be accessed through the
Maintenance menu
(menu button → Maintenance menu → Cooling).
4.7.1 Free cooling
An independently operating cooling system can be connected to the heat pump’s brine
circuit.
A circulation pump draws cool brine from the brine circuit and pumps it through a
cooling circuit. As the brine passes through the circuit, heat is extracted from indoor air.
After the cooling circuit, the brine is fed back into the brine circuit.
