The following number of universal inputs are available for the iniviual types of evices: RMS705: 8 inputs If more inputs are require, their number can be increase with the help of extension moules. RMZ785: 8 inputs RMZ787: 4 inputs maximum of 3 extension moules can be connecte (maximum from 2 x RMZ785 an 2 x RMZ787). The maximum number of inputs is therefore as follows: RMS705 + RMZ785 + RMZ785 + RMZ787: 28 inputs ctivating the function Recommenation ll available inputs can always be use. If they are not require for the system s functionality, they can be use for isplay purposes. Inputs not require are to be set to Digital. Each input can be assigne an ientifier. The ientifier also efines the unit of the input. The following ientifiers are available: Outsie temperature 1) C % g/kg kj/kg W/m² m/s bar mbar Pa ppm Universal (universal input with one ecimal place, resolution , increment 0.1) Universal 0000 (universal input with no ecimal place, resolution , increment 1) Digital [Controller 1] remote setpoint ajuster (remote setpoint absolute for controller 1) 1) [Controller 2] remote setpoint ajuster (remote setpoint absolute for controller 2) 1) [Controller 3] remote setpoint ajuster (remote setpoint absolute for controller 3) 1) Pulse 1) The ientifier provies aitional functionality (refer to subsection "Special analog inputs") 25/178 HVC Proucts 5 Inputs

If, before, a power failure occurs, the ata of the current event will be lost. ut the events that have alreay been store will be retaine. If the measure value signal at the terminal is no longer available, logging will be aborte an iscare. When the signal is active again, logging will be restarte. If another event cycle occurs within 5 minutes, the preceing event cycle will not be save. 6.3 Operating hours Operating hours Purpose There are 4 types of hours run counters available. They acquire the number of operating hours of any piece of equipment via a igital input signal. In aition to the total number of hours run, the number of operating hours since the last service visit are acquire. When the value of the service interval is reache, the RMS705 elivers a freely efinable service message. Counters "Hours run since service" continue counting until they are reset to 0 via ata point Reset. Resetting the counter "Hours run since service" has no impact on the counter for the total number of operating hours. The service messages of the hours run counter appear on fault isplay "Main menu > Faults". Each hours run counter can be assigne a specific name. On the passwor level, the counter can be set to a certain output value.

76 Run priority changeover with the linear step switch Run priority changeover is only available with the linear step switch, that is, when the loa outputs have steps of equal size. In aition, the combination of comman an loa with outputs -D must be uniform. Run priority changeover can be accomplishe by: The sequence selector on the operator unit Perioic changeover (weekly) ccoring to the number of operating hours First in first out It is possible to have simultaneous activation of several changeover moes. Example: Note Changeover takes place as follows: Perioic changeover with 4 aggregates. Week 1:,, C, D Week 2:, C, D, Week 3: C, D,, Week 4: D,,, C Week 5:,, C, D etc. The main menu shows the aggregates presently involve in the changeover process.

Changeover accoring to the hours run Note First in first out When the sequence selector is set to "uto, changeover accoring to the hours run can be activate. In that case, changeover of the lea aggregate takes place epening on the number of operating hours. Changeover accoring to the hours run ensures that, after a certain perio of time, the number of operating hours of the iniviual aggregates will be pretty much the same. Main menu > Commissioning > Settings >... or Main menu > Settings > ggregates > Rotary step switch > Rotary step switch 1 2 > Changeover interval ----, h --- When the perio of time for the changeover interval is set to "---", there will be no automatic changeover accoring to the number of hours run. Rotation accoring to the number of operating hours can be effecte with or without taking into account the changeover ay an changeover time. For that, the changeover ay an changeover time must be activate. When the perio of time set has elapse, the next aggregate will become the lea aggregate at the changeover time for perioic changeover. If only moulating aggregates are connecte, the number of hours run are counte when the moulating aggregate operates at > 80 % of its capacity. When the sequence selector is set to "uto", continuous changeover of the lea aggregate can be activate. If several aggregates are in operation an the loa rops, the aggregate to be switche off is the aggregate that was switche on first. Changeover accoring to the First in first out principle ensures that, after a certain perio of time, the number of operating hours of the iniviual aggregates will be pretty much the same.

82 ssignment of loas (flexible step switch only) With the flexible step switch, the loa shoul be assigne to the aggregates in a way that the number of aggregates in operation are as small as possible an that optimum control can be achieve uner part loa conitions. For that purpose, the output ata of each connecte aggregate must be set on the rotary step switch. If the loa output is configure as linear ( ), the minimum output (0 % loa signal) an the maximum output (100 % loa signal) can be set. Then, the rotary step switch assigns the loa to the aggregates. The aggregates must be set an connecte as follows: Output of aggregate aggregate aggregate C aggregate D. s the following examples show, it is not the actual output that is ecisive for the RMS705, but the ratio of the various loas.

Main menu > Commissioning > Settings >... or Main menu > Settings > ggregates > Rotary step switch > Rotary step switch > Runup elay m.s m.s Locking time m.s m.s Restart time m.s m.s Runup elay: The runup elay ensures that when switching to the next higher step, the set elay time will always be observe before the next step is switche on. It is thus mae certain that in the case of a refrigeration machine, for example, one stage is starte before the next stage is switche on. Locking time: The locking time ensures that after switching off, a step remains off for at least the perio of time set. It is thus mae certain that the compressor, for example, remains switche off for the selecte perio of time. Restart time: The locking time ensures that on completion of the perio of time set, the aggregate may be switche on again. This time starts from the moment the aggregate is switche on. It is thus mae certain that the heat pump, for example, is switche on again only after a certain perio of time has elapse. 87/178 HVC Proucts 8 ggregates

It is thus possible to switch on the evaporator pump of the first refrigeration machine, for example, enabling the flow sensor to acquire the correct flow temperature as the water passes by. If run priority changeover (linear step switch) is activate, the aggregate s precomman output is switche on with the current priority With all other types of rotary step switches, the precomman input in normal operation acts on precomman When the precomman input is configure, aggregates can be switche on only if a precomman is pening an the precomman runup time has elapse. The precomman input can be use as a release for the rotary step switch. It is also active when no precomman output has been configure.

This section gives a final escription of the iniviual applications an associate configuration an communication settings require for transmitting the heat / refrigeration eman. The RMS705 can generate or evaluate the eman signal in connection with the following applications: Consumer Primary controller Generation Consumer an primary controller Consumer an generation The examples are explaine with the help of hot water networks, but also apply analogously to chille water networks Setting rules Heat / refrigeration eman is always marke with a cross (controllers 1 3, primary controller) if the eman from the relevant controller shall be passe on.

This means that with this controller, it is always only one sequence that is active (either heating or cooling). Controller 3 is also connecte to a 2-pipe system. This means that controller 3 can use its fan coil for heating only or cooling only. ctivation takes place by configuring a 2- pipe system an the respective heat / refrigeration eman.

140 9.5 Loa control (locking signals an force signals) Function an activation Function Examples of loa reuction Examples of loa increases ctivation Loa control enables heat generation to reuce the amount of heat rawn by the heat consumers (loa reuction via locking signals), or to increase it (loa increase via force signals). In the case of loa control via locking signals, a ifferentiation is mae between critical an uncritical locking signals. In the case of force signals also, a istinction is mae between critical an uncritical signals. These ifferentiations allow the heat consumers to respon to loa control in ifferent ways. Examples where a loa reuction can be triggere are the following: Protective boiler startup (boiler temperature is still below the minimum boiler temperature): Loa reuction via critical locking signals Shifting DHW priority (if the boiler temperature setpoint is not reache uring DHW heating, the amount of heat rawn by the heating circuits will be restricte): Loa reuction via uncritical locking signals bsolute DHW priority (DHW heating is given priority over the heating circuits; the heating circuits may not raw any heat: Loa reuction via uncritical locking signals Example where a loa increase is emane: Overtemperature protection (pump overrun, mixing valve overrun) The RMS705 itself oes not respon to locking signals an force signals but passes them on in the relevant heat eman zones for further hanling by the RMH760 an RMK770.

"Device aress" "Decentral bus power supply" "Clock time operation" Each bus user requires its iniviual evice aress. Device aresses 254 an 255 are reserve for special functions. Device aress 255 is use to eactivate communication (no exchange of process ata). If 2 evices on the Konnex bus have the same evice aress set, a fault status message "> 1 ientical bus aress" will be elivere. For small plant, ecentral bus power supply is aequate. This represents the efault setting. For etaile information, refer to Data Sheet N3127 (KNX bus) or asic Documentation P3110 (KNX communication). When there is no bus power supply, a fault status message "No bus power supply" will be elivere. ccess with the OCI700.1 service tool is not possible without communication. If the system shall use a common time of ay, one of the evices must be efine as the master, all the other evices are slaves. 153/178 HVC Proucts 12 Communication

154 Using "Remote setting clock slave = Yes", the time of ay can be ajuste at the respective slave. This is then sent to the master, which passes it on to all the other evices. When using setting "utonomous", the evice oes not receive or sen the time of ay. "Remote setting clock slave" "Remote reset of fault" Function "Remote setting clock slave" enables the operator to set the time of ay an the ate on any of the clock time slaves. The new values are then sent to the clock time master via Konnex bus. The master then elivers the time of ay to all bus users. Hence, for the operator, operation is the same as on the clock time master. When communication is activate, the effects are the following: Fault status messages are always elivere via Konnex bus an can be further hanle by other Synco evices Fault status messages from other Synco evices are shown on the isplay uner: Main menu > Faults > Fault status message bus Fault status messages from other Synco evices can be elivere to a fault relay (refer to section 11.5, Fault relay") ll fault status messages can be acknowlege from a remote location (e.g. from the operator station with the OCI700.1).

The alarms for the inputs are only active if the input is connecte before commissioning is complete If an input ientifier is change, all associate settings will also change (e.g. Xp was 28 K, now it is 10 Pa) Orer of configuration: First the basic configuration, then the extra configuration Connection choices: lways from the arrow ( ) to the line ( ) From uppercase letter to lowercase letter From lowercase letter to uppercase letter From function to input: "x" to "x" From output block to output terminal: nalog "Y" to "Y" Relay "" to "" Output functions must be connecte to the relevant connection terminals; every output terminal can only be use once (e.g. N.1 for motor 1) s shown in the general configuration iagram (subsection ), the RMS705 hanles the function blocks line by line from left to right. Calenar is the first function block, Motor 6 the last. Outputs of a function block that are fe back to a preceing block will only be available with the next cycle. This shoul be taken into consieration when making the configuration. The result of logic block 1 is fe to logic block 2. This means that in the same cycle, the result of logic block 1 is alreay available with logic block 2. Hence, the input signals of the RMS705 are optimally hanle in terms of time. 163/178 HVC Proucts 15 enum
