3.0 2416 Controller
If all segments are used so that there is no 'End' segment, then on completion the
program automatically goes into 'Dwell'.
Dwell segments of length zero can be included. This is a way of allowing space for future
program changes.
For an example of program creation, see section 3.3.6.
3.3.2
Multi-program model (2416P8)
The 'Program Edit' list contains the extra parameter 'PrG.n' and the 'Run' list contains
the extra parameter 'PrG'. These features allow selection of the program to be edited or
to be operated.
The extra segment type 'cALL' allows one program to call another as a subroutine; use
this feature to create one or more long programs.
3.3.3
Holdback
"Holdback' can be used to prevent the program from operating ahead of the actual
heating or cooling.
In the program list, scroll
to the 'Holdback' parameter and use down
or up
to
set the holdback type as follows:
Band
Holdback applies to both heating and
cooling
Lo
Holdback applies to heating only
Hi
Holdback applies to cooling only
Off
Holdback is off
Set 'Hb.V' to the value in °C beyond which holdback is to operate. Type 'BAnd' and a
value of 10 °C is often a suitable combination, if holdback is required. In this case, if the
actual temperature deviates outside ±10 °C from the working setpoint, the holdback
lamp of the front of the controller flashes and the program is held up until the
temperature comes within range again.
The standard setting for holdback is OFF.
3.3.4
Program Cycling
The 'Loop Count' parameter 'CYC.n' can be set to control the number of times the
program is run.
If 'CYC.n' = 1, the program stops at the end segment.
If 'CYC.n' = 5 (for example), the program runs 5 times: at the 'End' segment it returns
to segment 1, until the 5th time through when it stops.
If 'CYC.n' = cont, the program never ends: it cycles continuously.
3.3.5
Running a Program
Press Run/ Hold to light up the 'Run' light. The program starts to operate.
To view the progress of a program from the 'Home' list, press scroll
to reveal the
current segment ('SEG') and the total program time remaining in hours ('PrG.t').
