Stopping and Starting Control
It is possible to stop and start the controller without altering the setpoint. Press Scroll until the
legend
m-A
(manual/auto) appears. In the 2132 or 2116, manual means “off” and auto means
“on”. Press Down or Up once to show the current on/off state:
mAn

Press or to change between manual and auto (off and on) as required.
Note that timer modes 1 & 3 set the controller to
mAn
at the end of the timing period. If the
controller unexpectedly does not control it may be in manual, possibly as the result of previous
use of the timer function.

Altering the Ramp Rate
It is possible to limit the rate of heating by setting a ramp rate only if the timer feature is not in
use. To enable direct setting of the ramp rate, first ensure that the
StAt

dwEl
parameter are both set to

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

use, there is a “working setpoint” which can be viewed at any time by scrolling to

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).
