Electronic Thermostat

1. With the air select lever set to “VENT” and the air

source select lever to “CIRC”, start the air condi-
tioning.

2. While shifting the temperature control lever from

“FULL COOL” through the “FULL HOT”, check to
see if the magnetic clutch turns on and off.
(*Note that the time required to reach the “OFF”
point depends on the warm or cold air at 3.5 

±

0.5

°C at the electronic thermostat thermo sensor).

3. While the magnetic clutch is turning “ON” and

“OFF”, measure the voltage between chassis side
connector terminal No. 1 and No. 2.
