Auto/
Manual
Disabled. The unit is always in 'Auto' mode
RUN/HOLD
-
Used to start, stop or pause a program. Short presses
cause it to alternate between 'Run' and 'Hold', but if it is
held for 2 seconds the programmer goes into 'Reset' mode
where it behaves as a simple controller.
Up + Down
+
To adjust the value of a parameter. Used to change the
setpoint when the unit is being used as a simple controller
('Reset' mode). Holding down gives an accelerated
parameter change.
Page
Allows access to the parameters within the controller; most
lists and parameters are hidden from the operator as they
contain factory-set values which should not be altered. A
single press of the page key shows the temperature units,
normally °C; further presses reveal the lists indicated in the
Navigation Diagram.
Scroll
Allows access to the parameters within a list. A single press
displays the temperature units; further presses reveal the
parameters in the current list. Some parameters are
display-only, others may be altered by the operator.
Page + Scroll
+
Press together to cause an immediate return to the 'Home
List'
Run & Hold
Indicate the current mode: 'Run', 'Hold', or 'Reset' (Reset:
both lights off).
'Run' flashes at the end of a program.
'Hold' flashes during holdback (when the program is paused
to allow the temperature to catch up with a heating or
cooling rate which is too fast).
Output
Indicator
OP1 indicates that the programmer is calling for heat to be
supplied.
OP2 is not used.
SP2 and REM
Not generally used; indicate 'Second' or 'Remote' setpoint
in use.
Operation as a Simple Controller
Press RUN/HOLD for 2 seconds to go into 'Reset' mode. Use down
or up
from the
'Home List' (i.e. when the temperature is displayed) to adjust the setpoint. The unit
starts to control in the way indicated in Fig. 1.
Note that to use the Ramp Rate feature, as in Fig. 2, it is necessary to create a
program. See the following sections.
