2132/2116 Controller
4 MC02 – .08
2.5 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 for off, and Auto for on.
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.
2.6 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 parameter and dwEl
parameter are both set to OFF (see sections 3.1 and 3.2).
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).
