Altering the Ramp Rate
It is possible to limit the rate of heating by setting a ramp rate. Press Scroll
4
until the legend
SPrr
(SetPoint ramp rate) is displayed. Use Down
T
or Up
S
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
T
or
S
.
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).
