2.7 Digital Core Temperature Sensor
Located on the back wall of the cold storage assembly,
the sensor measures the temperature of the cold storage
core. The control module evaluates the signal and
adjusts the charging process accordingly.
The switching point is 30 °F (–1 °C). The charging mode
is active at temperatures greater than 30 °F (–1 °C) and
inactive at temperatures less than or equal to 30 °F (–1
°C).
The digital core temperature sensor’s performance can
only be analyzed through the use of a special tool
available from Webasto.

2.8 Ambient Temperature Thermostat
Located behind the compressor, an ambient temperature
thermostat is provided for the purpose of deactivating
the BlueCool Truck System during cooler weather periods
when bunk cooling is not desired.
The thermostat contacts open at 45 °F (7.2 °C) thus,
deactivating the system during cold weather. The
thermostat contacts remain open until the ambient
temperature reaches 60 °F (15.5 °C) at which point the
contacts close and the system is allowed to operate.
