Sensors
Heat measurement in split air conditioners is performed via NTC (Negative Temperature Coefficient) sensors. NTC sensors are circuit
elements whose resistance decreases if the heat increases. Indoor environment sensor and evap sensor are NTC elements.
Such sensors do not have a standard resistance value. They only have a usage resistance range. NTC will show different resistance
values depending on the temperature of the environment it is in.
