Note)
1) F-DEF-sensor and Bimetal work in parallel.
2) At the first power on, an open error (5V input to
MICOM) can be detected by self-diagnostics. A
short error will be ignored.
3) In self-diagnostics during a normal operation, only
an open error can be detected.
4) The F-DEF heater will be off at the set temperature
after the bimetal is off.
1) Key Scan and display operation.
The model uses a decorder IC which 4 inputs and 9 outputs.
If the IC 9 decorder (TC4028BP) receivesd signals from
MICOM pins (3
∼
6), an output signal per 2 miliseconds
comes out from Q3, Q41, Q8, Q6, Q9, Q7, Q0, Q2, and Q4
pin in sequence. This signal enters to a driver IC input
terminal of the CoolSelect Zone
TM
PCB and IC5 (TD
62783AP), then approximate 11V peaks will generate from an
output terminal as shown on the next page.
