3.2 Converting °F to °C (vice versa)

You must remove the printed circuit board from the case
in order to change from the Fahrenheit to Celsius (or vice
versa). This change must be performed by a qualified

technician in order to avoid damage to the unit.
Disconnect the power from the unit before proceeding.

Degrees Fahrenheit and degrees Celsius are selectable
parameters. All you need to do is change the location of the
shorting jumper at S3, using needle-nose pliers.

1. Disconnect all wires

and move the unit
from the panel (if
installed).

2. Remove the printed

circuit board from
the case as
described in

Section 3-8

.

3. Follow the instructions to convert to:

Celsius:

.

The unit will display degrees Celsius when the shorting jumper
is connected to both pins at S3. Refer to 

Figure 3-2

, Detail A.

Fahrenheit:

.

The unit will display degrees Fahrenheit if the shorting jumper
at S3 is NOT connecting the 2 pins. Refer to 

Figure 3-2

,

Detail B.  By keeping the shorting jumper on one pin, you are
keeping it handy in case you want to change the display back

to degrees C.
