▶ Function
Detects signals from the sensor and controls the current system.
▶ Description
- The water level sensor is connected to pin 4 of CN7.
- The frequency of the level sensor changes according to the water amount in the tub.
- Then, the frequency is input to MICOM pin 48 for detecting the water amount.
- The DHSEH sensor is connected to CN7 pin 5 and CN6 pins 3,4.
- The resistance of the temp. sensor changes according to the ambient temperature. The
changed resistance is applied to R50 and R51.
- The voltage applied to R50 and R51 is decided according the temp. MICOM stores
the value.
- When voltage is applied to MICOM pins 22 and 23, MICOM compares it to the predefined
one before detecting the current temp.
