The following sensors are installed in the chiller as standard:
for each refrigerant circuit:
- condensation pressure -> for condenser fan control
- suction gas temperature
- suction gas pressure (evaporation pressure)
Chilled water circuit:
- chilled water inlet temperature
- chilled water outlet temperature
- flow sensor
- frost protection thermostat
- intermediate temperature (free cooling)
In units with free cooling exists an additional sensor for the
chilled water temperature which is measured at the free cool-
