Control computer

A control computer is used to automatically calculate the heat demand in the house where
the heat pump is installed and to ensure that the correct amount of heat is produced and
emitted where necessary. There are many different values (parameters) that must be referred
to during the calculation of the heat demand. Use the control computer to set and change
certain values that have to be adapted according to the house demand.
The display window, keypad and an indicator are on the front of the control computer. It
consists of a simple menu system that is used to navigate the desired settings and values.
