How do you switch off the automatic climate control?

The indicator lights on the left and right switches marked 'auto' are always illuminated and system stays in automatic mode no matter which way they are pressed.<br>
<br>
All I can find in the manual is 'the system is always at operational readiness, except when manually switched off'....but doesn't say how to switch it off. <p>182.cambridge-01rh16rt.ma.dial-access.att.net
