They have: - Resistance inversely proportional to temperature
- They are temperature-dependent resistors
- Composition of iron oxide, magnesium and chromium, barium titanate.
Environment sensor to control the ambient temperature
Internal coil sensor freeze protection
compressor protection against liquid stroke;
system protection against lack of refrigerant
Below 0 ° C shuts off Compressor
Above 7ºC turns on the Compressor
Sensor of the external coil used in the condenser unit in order to avoid freezing of the external coil when in reverse cycle (very low external temperature).
