2.4 Altering the Setpoint
With the display at “home”, showing the measured temperature, press Down  or Up  once to
display the setpoint; press again or hold down to adjust it. The display returns to the measured
temperature when no key is pressed for 0.5 seconds.
2.5 Altering the Ramp Rate
It is possible to limit the rate of heating by setting a ramp rate. Press Scroll  until the legend
SPrr (SetPoint ramp rate) is displayed. Use Down  or Up  to display and adjust the value.
The ramp rate sets the maximum rate of heating or cooling in degrees per minute. A value of OFF
cancels the ramp rate, allowing heating and cooling at the maximum rate. When this feature is in
use, there is a “working setpoint” which can be viewed at any time by scrolling to
w.SP and
pressing  or .
Fig 1 and fig 2 indicate the possible difference between running without and with a ramp-to-
setpoint value (depending on the load and the value used).
