POINT / T

o

 CURVE

. The cur-

rent temperature set point
flashes on the display.

n

Press the push-button.  The word 

OFF

 is displayed indicating that the

termperature curve is deactivated.  If this is not the case, see below
to deactivate the curve.

Repeat the following steps for each of the six points:

n

Press the push-button once again.  The day number is displayed,
alternating with the word "

day

".

n

Using the adjustment knob, set the day number to the desired value.

n

Press the push-button once again.  The current temperature set point
is displayed, alternating with the word "

set

".

n

Using the adjustment knob, adjust the set point to the desired value.

Once the six points of the curve have been specified, activate the curve as
explained below.

NOTE

: Make sure the temperature curve is deactivated before specify-

ing new points (see below).
