4.11 Water Temperature Sensors
The outlet and inlet water temperature is measured by a 10kΩ NTC (See Table 13). Both NTC are
equal, but connected to different cable colors (blue wires to inlet water / red wires to outlet water).

4.12 Box Temperature Sensor
The Box air temperature is measured by a 220kΩ NTC (See table 12) and is assembled on the
control unit back panel, in order to monitor the temperature inside of the sealed box.
