MEMORY CHECK

The automatic diagnosis makes it possible to check the capacity to memorize the temperature set by the control unit Q21a

Operate as follows:

• Rotate the ignition key to the "RUN" position
• Press the "AUTO" key

• Press the "TEMP+" a few times, until the identification code "HI" appears on the upper display (TEMP)
• Press the "AIR+" key until the fan reaches maximum speed and eight bars appear on the lower display (AIR)
• Press the "RIC" key and one of the right-hand keys (air distribution) the one set automatically.
• Rotate the key to the "STOP" position; a few moments later rotate it to the

"RUN" position. The previously stored settings should now be operational once again and no changes should have occurred: temperature set to "HI", fan at maximum speed, air flow with recirculation and a certain distribution

If the settings are not stored replace the control unit Q21a
