1. Introduction
Note: This manual should be read in conjunction with the standard SX100 Operator's
and Site manuals
The SX100e is a development of the SX100 controller with enhanced features, which have
been incorporated to simplify and improve the programming and operation of the controller,
particularly when used with heat exchange packages.
The differences in specification and operation of the SX100e in comparison to the SX100 are
outlined below.

2. General product information
2.1 Front facsia
1. In the top left of the controller front there are now only three LED's instead of five - these are:
-AT - indicating if auto tune is active
-Thermometer Symbol - showingthatAlarm 2isactive (EasiHeatbypassvalveenergized)
-MAN - indicating if the controller is in manual mode
2. The 'PROF' button has been renamed 'PROG'
3. The 'RUN/HOLD' button has been renamed 'RUN/STOP' as it more accurately describes its
new function.
4. In the top right of the controller front there are now only three LED's instead of four - these
are:
EV1 -Pump output
EV2 -Alarm 1 active - EasiHeat volt-free contact for remote high temperature alarm indication
EV3 -Loop Alarm active

2.2 Functional changes
1. The creation of two security levels (note that to enter from Base Mode it is necessary on
the SX100e to press the PROG and UP buttons together before entering the appropriate
security code):
Level 1 security code (Factory set to 10 and not changeable)
Allows access to:
-Operator Edit mode
This is best used for day - to - day changes to program run times etc. Only the basic
temperature selection and running times are available in this mode, which simplifies any
alterations, reducing the possibility of mistakes being made.
Level 2 security code (Factory set to 100 and not changeable)
Allows access to:
-Operator Edit Mode
-Controller Define Mode
-Program Define Mode
This is for engineers and more experienced personnel who have sufficient expertise to
alter the major settings within the controller such as PID and hardware options etc.
2. Real time clock now works in actual time, not elapsed time from the start of a program.
3. Digital Input Board now fitted as standard
4. LinearOutputBoardnowfittedasstandard(tooutput3). Note-thisreplacestherelayoutput
on the SX100.
It is vital when substituting an SX100e for an SX100 - that any power supply
connection to terminals 10, 11, or 12 are removed first - otherwise the controller
will be severely damaged. (Output 2 on the SX100e can be used instead of Output
3 on the SX100).
5. Outputpowerisnowcontinuallyshownonthe controller display, expressed as a percentage
(unless the controller is in one of the programming modes)
6. The 'Control setpoint' on the SX100 has now been renamed 'Fallback' temperature for the
SX100e. This is now only available for configuration in CONTROLLER DEFINE mode.
This is the temperature the controller will attempt to maintain should the process value fall
below this level, even if a program is not running. This should normally be set to zero or no
more than 5 deg C, otherwise it may override a running program, or allow the control valve
to open at times when the heating should not be active.
7. 'Final Setpoint' is now renamed 'Target Set Point'
8. There are now three effective external options for the controller. Refer to Table 1 page 4.

9. The SX100e has only two heating programs offered when running in each of the stand alone
modes:
-PROG 1 - TIMED
-PROG 2 - CONTINUOUS
10. Each program now has only three segments. These are:
-SEGMENT 1 RAMP UP
-SEGMENT 2 DWELL (MAINTAINS TEMPERATURE AT TARGET SET POINT)
-SEGMENT 3 RAMP DOWN (TO FINAL SET POINT)
11. InBMSmode-onlyprograms2to8areavailable. Thesecanbeconfiguredfortemperatures
and ramp times, but heating start and heating finish control is from the external building
management system.
12. Ifpowertothecontroller is switched off and thensubsequentlyturnedbackon, any program
which is set to run at that time will re-start automatically and ramp up to the target set
point.
13. If External option is set to 'BOTH' a feedback to the run input on the controller can be used
to terminate a program should, for instance the circulating water pump fail. When the
feedback signal is re-established the program will then ramp back up to the target set point.
14. When changing from one program to another in stand alone or in BMS mode, the set point
temperature will ramp up or down as appropriate to the new value. It is not now necessary
to stop running the current program before changing to the next.
Note: there may be a delay of up to a minute before the program starts automatically

IM-S27-12 CH Issue 1 5
15. If changes have been made to parameters in either of the CONFIGURATION MODES,
then when returning to BASE MODE, four LED dots may appear on the upper display
beneath the main digits.
This indicates that the configuration changes have now invalidated any previously set up
parameters in Program Define mode.
No programs will be able to run until changes have been made in Program Define or
Operator Edit modes.
The 4 LED dots will then disappear showing that the operator has recognized this
condition and taken the appropriate action.
3. Controller modes
The programmer has four operating modes (plus normal configuration mode and hardware
configuration mode):
Base Mode Display status - RUN, SET, PRG indicators Off.
(No security level) No program is running in this mode
Operator Edit Mode Display status - 'Op.Edit' message
(Security level 1 or 2)
Program Run Mode Display status - RUN, EV1 indicators on
(Security level 2) Selected Program running
Program Define Mode Display status - 'Def.Prog' message
(Security level 2) Used to view and edit programs
Controller Define Mode Display status - 'Def.Ctrl' message
(Security level 2) Used to define the controller characteristics
Configuration Mode Display status - 'Conf' message
(Config. security code)
Additional information and details of factory settings when used for the EasiHeat application are
detailed in the following sections

4.1 Selecting a program
In order to change the selection of a program when the SX100e is operating as a stand-alone
controller, it is necessary to enter 'OPERATOR EDIT' mode.
If it is necessary only to change the program selected, refer to Table 2 below.
Table 2 SX100e Operator edit mode
4.2 Defining a program
Follow the instructions on Table 3 below to select a new program, and/or to change the
parameters of the required programs as indicated.

4.3 Running a program
Program 1 (timed) - if the controller is set to run on the current day and time, the program
will start automatically once the controller has been switched on
(there may be a delay of up to a minute for this to happen after initial
power up)
Program 2 (constant) - having selected program 2, it is necessary to press the RUN/STOP
button once.

IM-S27-12 CH Issue 18
4.4 Overriding a program
Inprogram1(timed)orprogram2(constant) the program can be started or stopped by using the
RUN/STOP button.
Program 1 - (Timed)
Stopping Program 1:
-Ifprogram1isrunning,itcanbestoppedbypushingtheRUN/STOPbuttonforapproximately
5 seconds.
-Thesegmentno.willthenchangeto'3'andthetargettemperaturewill beseentorampdown,
before finally terminating.
-The RUN LED will then go off.
-The program will then restart at the next scheduled start time.
Starting Program 1:
-If program 1 is not running, it can be started by pushing the RUN/STOP button briefly.
-Segment no. 1 will then be indicated on the display.
-The RUN LED will then illuminate and desired temperature will be seen to ramp up towards
the target temperature.
-When target temperature is reached , the segment no. will change from 1 to 2.
-The program will then stop at the next scheduled stop time.
Program 2 - (Constant)
Stopping Program 2 :
-Ifprogram2isrunning, itcanbe stoppedbypushingtheRUN/STOP buttonforapproximately
5 seconds.
-Thesegmentno.willthenchangeto‘3’andthetargettemperaturewill beseentorampdown,
before finally terminating.
-The RUN LED will then go off.
-The program will NOT restart until the RUN/STOP button is pressed again.
Starting Program 2:
-If program 2 is not running, it can be started by pushing the RUN/STOP button briefly.
-Segment no. 1 will then be indicated on the display.
-The RUN LED will then illuminate and desired temperature will be seen to ramp up towards
the target temperature.
-When target temperature is reached , the segment no. will change from 1 to 2.
-The program will then continue running.
