AN7

IN

Used for initial balancing of the bridge circuit (absolute humidity sensor). This input

is an analog input terminal from the AH sensor circuit, and connected to the A/D

converter built into the LSI.

AN6

IN

AH sensor input.

This input is an analog input terminal from the AH sensor circuit, and connected to

the A/D converter built into the LSI.

AN5-AN3

IN

Heating constant compensation terminal.

10

AN2

IN

Input signal which communicates the door open/close information to LSI.

Door closed; "H" level signal(0V).

Door opened; "L" level signal(-5V).

11

AN1

IN

Input signal which communicates the damper open/close information to LSI.

Damper opened; "H" level signal(0V:GND).

Damper closed; "L" level signal(-5V).

12

AN0

IN

Temperature measurement input: OVEN THERMISTOR.

By inputting DC voltage corresponding to the temperature detected by the thermistor,

this input is converted into temperature by the A/D converter built into the LSI.
