7.1 Adjusting the temperature
set point
Adjust the required set point by turning the
set point adjuster (43) by hand. The adjust-
ment diagrams (see Fig. 7-3) can be used as
a guide to find the first approximate value.
Set point adjuster
Î
Turn the set point adjuster clockwise (

)
to increase the temperature set point.
Î
Turn the set point adjuster counterclock-
wise (

) to reduce the temperature set
point.
The thermometer (4) installed on the down-
stream side on site allows the adjusted set
point to be monitored.
Higher set point temperatures can be
adjusted in increments as required. However,
to lower the set point temperature, proceed
in steps of 10 to 20 °C/50 to 68 °F. When
doing so, wait for the process medium to
cool down before continuing. Watch the
thermometer.
