Getting Started
The CSMC is a Microprocessor Compensator/Optimiser with a full range of advanced features.For ease of use Invensys have designed theCSMC to be as simple as possible to program.Before switching on the CSMC power check thatthe battery is connected and that commissioninghas been completed (see DS 2.541A for details).All Key code settings have a basic programmeas standard, which can be changed by the user ifrequired.
To initially configure the CSMC to control yourplant the following functions must be reviewedand changed if necessary to meet your specificrequirements:
Note: If the time and date (function key 4) is leftunset the CSMC will remain in a suspended stategiving no output. This avoids unwanted outputsoccurring whilst the CSMC is being configured.
Once the CSMC has been configured the timeand date should be set.
Compensator Key codes A00 to A08 (Also A09to A12 if a dual compensator configuration isused) (see pages 22 and 28).
Time, Date and Timeschedule Function keys 4and 6 (see pages 9, 13 and 15).
The CSMC can be configured to control a numberof different types of application as follows:
Compensator/Optimiser, Single Loop, HWS Timeschedule Output only.
Compensator/Optimiser, Single Loop, BoilerSequence Control, No HWS Output.
Compensator/Optimiser, Dual CompensatorLoop Control, No HWS or Boiler Output.
Compensator/Optimiser, Single Loop, HWSTemperature/Time Controlled Output.
Optimiser Only, No Compensation Output, HWS Time Schedule Output.4

All other settings can be changed to the usersrequirements at a later date, if required. Therecord pages near the back of this User Guideshould be used to record any changes made tosettings for future reference.
To make the CSMC easier to understand the Aand B codes are arranged in five sections. Themain section covers the general key codes, andthe other sections cover each of the otherapplication specific key codes.
The CSMC is self adaptive on the compensationratios and the optimum on/off settings. If selfadaptive functions are not required they may beindividually cancelled by using Key codes A08,B24 and B25 respectively.
Compensation loop 2 is not self-adaptive.

How to use the Keyboard
Some functions may be reviewed without the useof a security code but in all cases if a parameter isto be changed one of three security codes mustbe entered.
Press the SECURITY key and the display willshow [ SEC ].
Enter the appropriate 4 figure security codefollowed by the ENTER key. See page 7 for thestandard security codes. If an incorrect code isentered, the display will revert to normal.
If the correct code is entered the display will show:
Low Security [ HELLO ] security KEY symbolcontinuously on.High Security [ HELLO] security KEY symbolflashes.Service Security [ HELLO SEr ] security KEYsymbol flashes.
The CSMC will automatically exit from security ifno keys are pressed for approximately 90seconds. If necessary, pressing the SECURITYkey while the display says [ HELLO ] or [ HELLO SEr ] will immediately exit security.6

Manual Overrides
REVIEW : No SecurityCHANGE : Low SecurityHaving pressed function key 2 the BOOST, DAYand NIGHT status displays will come on, if you donot wish to override any of these then press theENTER key. To override the CSMC into one ofthese modes press key 2 until the required modeis flashing and then press the ENTER key.Having pressed the ENTER key the display willshow the PUMP symbol and either [ A ] or [ 1 ] toshow the pump status. [ A ] = Auto, [ 1 ] = On. Tochange the override press A or 1 followed by theENTER key. To leave the pump as it is just pressthe ENTER key.NOTE: The pump may not be overridden off.The HWS output and actuator outputs may alsobe overridden in the same way as the pump.
HWS Output TAP symbol on[ A ] = Automatic[ 0 ] = Override off[ 1 ] = Override on
Actuator Output VALVE OPEN and CLOSEsymbols on
[ A ] = Automatic[ 0 ] = Valve stops in its present position[ 1 ] = Actuator open[ 2 ] = Actuator close
NOTES:1.The boiler cannot be directly switched on or off.
If the boiler symbol is flashing, this may becaused by a limit condition or another override, forinstance Boost. Check all overrides and limitvalues.
2. If the dual compensator option is selected thenthe valve override will apply to both loops.
3.Overriding the optimiser for compensator loop 1will automatically override loop 2.
4. If the CSMC has no HWS output (i.e. as dualboiler or dual compensator) the HWS overridefunction can still be set but has no effect. 11CSMC3805

REVIEW : No SecurityCHANGE : Low Security
Day Extension works in two ways. If requestedduring an on period the days occupancy will beextended by the time set in key code B00 (keycodes are detailed in a later section). If it isrequested out of an occupancy period the plantwill be brought on for a set amount of time asdetermined by key code B01.
To select the day extension, or timed on period,press function key 3. The display will show either[ dE 0 ] or [ t0 0 ] i.e. the day extensionor timed on period is off, to turn it on press key 1followed by the ENTER key. Key 0 will turn theperiod off.
The display will now show [ 0 6 ].
Saturday and Sunday may be programmed inthree ways; as off, on or on once. If Saturdayor Sunday are programmed off then those dayswill be omitted each week. If they are set to onthe days will obey the standard time programmeset. If they are set to once only they will obeythe programme set at the next weekend, but willthen reset themselves to off for subsequentweekends.
[ 0 6 ] will be displayed, i.e. day 6 is off. Day 6may now be programmed as follows:
[ 0 ] = off[ 1 ] = on i.e. follow the timeschedules set[ 2 ] = on once only then automatically resets
itself to 0
Press the appropriate numeric key followed by theENTER key and Sunday, day 7, will be displayed.Programme Sunday in the same way as Saturday.

Holiday Programmes
REVIEW : Low SecurityCHANGE : High Security
The Optimiser and HWS output may haveseparate holiday programmes. Each of them mayhave up to 99 holiday periods with each periodbeing either a day or a week in length.
To enter a holiday period press function key 5.The display will show [ Ab ] with [ A ] flashing.
Holiday programme [ A ] is for the OptimiserHoliday programme [ b ] is for the HWS. Output or Compensator loop 2.
The flashing [ A ] or [ b ] indicates the programmeto be set. The programme may be toggled in thesequence of [ A ], [ b ] and [ Ab ] by repeatedlypressing key 5. Select which timeschedule theholiday should apply to and press the ENTERkey. Now enter the day number 0 to 7 (0 is thecomplete week) and press the ENTER key.
Now enter the week number (1 to 53) and pressthe ENTER key. Press the EXIT key to leave thefunction or the MINUS key to programme anotherholiday for the same timeschedule(s).
The holiday programmes are automatically sortedinto chronological order.
The ENTER key is used when reviewing holidaysto move from one to the next in chronologicalorder.
To delete a holiday period, review the appropriateholiday program and enter 0 as the day number,00 as the week number and press the ENTER key.
In normal operation when a holiday period isreached the appropriate days/week will flash onthe LCD (Liquid Crystal Display) timeschedule.

Timeschedules
REVIEW : No SecurityCHANGE : High Security
The CSMC contains two independenttimeschedules.
Timeschedule [ A ] Optimiser scheduleTimeschedule [ b ] Independent Timeschedule(i.e. HWS or compensator loop 2 if the dualcompensator mode is selected).
Each timeschedule may have two on periods perday. The time should be set in the 24 hour clockformat and will consist of 4 digits.
To set a timeschedule press function key 6, [ ts A] is displayed. Select the timeschedules to bechanged by pressing A or B followed by theENTER key. The display will now show [ Pd X ]where X is the current day number (1 7). Eitheraccept this as the first day to set by pressing theENTER key, or choose another day number to
change (1 7) followed by the ENTER key.
The display will show the timeschedule type, theperiod (P1, P2, P3, P4), the day (1 7 see note 2below for days 6 and 7) and the current switchingtime, as shown below.
Enter the correct time (0000 2359) followed bythe ENTER key and the display will now changeto the next switching time. If a switching time iscorrect the ENTER key alone should be pressed.
NOTE:1. If only one on period is to be used in a day then
P1 is programmed to the on time, P2 and P3 to0000, and P4 to the off time.
2.Saturday and Sunday timeschedules areignored by the CSMC unless they are alsoselected from function key 3 Weekend Mode. 15

The A and B key codes are used to set thecompensator and optimiser parameters such astemperatures, limits and ratios.
The A key codes are generally used forcompensation functions and the B keycodes foroptimiser and miscellaneous functions.
To make the CSMC easier to understand, the Aand B codes are arranged in five sections. Themain section covers the general key codes andthe other sections cover each of the otherapplication specific key codes.
Various security levels are required for specifickey codes but access always follows the methodoutlined below.
Enter the appropriate security code followed bythe ENTER key. Press the A or B key followed bythe key code number to be reviewed or changedfollowed by the ENTER key. The current value for
this key code will now be displayed and a newvalue may be set followed by the ENTER key.
As with all programming, pressing the ENTER keywithout amending the value leaves it unchanged.A higher security level than that required willalways work.
The following pages show all the key codes givinga brief description followed by the parameterunits, the setting range, the value initiallyprogrammed into the CSMC and space to notethe actual value set if different from the defaultprogramme. The security level required is alsoshown.
For a full description of the operation of each codesee DS 2.541A. For Application Details seeDS 2.541B.

CAUTION
This device has a mains voltage supply. Local wiring regulations and usual safety precautions must be observed.Ensure good earthing.
Do not mix phases on any of the controller inputs or outputs. Before opening the controller to alter the switch settings, replace fuses or battery, first ensure ALL mains supplies
to and from the controller are correctly isolated as live terminals are exposed. All relay outputs including the actuator output must use a common voltage i.e. 220/240Vac or 24Vac. Do not mix
voltages. This is required to prevent the possibility of flashover from the 220/240Vac to the 24Vac. Do not switch on power supply until commissioning procedures have been carried out see page 1, DS 2.541A. Observe wiring precautions on DS 2.541A. This product contains a Lithium Chloride battery which is completely safe whilst in normal operation. Batteries
must be disposed of in an authorised landfill site. Do not exceed the maximum ambient temperature see page 30. Interference with parts under sealed covers invalidates guarantee. Design and performance of Invensys equipment are subject to continual improvement and therefore liable to alteration
without notice.
Information is given for guidance only and Invensys do not accept responsibility for the selection and installation of itsproducts unless information has been given to the Company in writing relating to a specific application.
A periodic system and tuning check of the control system is recommended. Please contact your local Invensys ServiceOffice for details.
