System. Besides this publication there are additional documents which contain further information about different components and functions of the e.r.i.c. System. • • • • • • The Regulator Manual, Edition 3 The Electric Wiring Planning Instructions Assembly Instructions Instructions for Use Bindings for the e.r.i.c. System Functional Control Forms Preparations It is always advantageous to calculate theoretical settings for the active regulators of the air terminals. In certain cases this may already be pre-programmed from factory. The sales office in question can inform you if this has been done. All factory settings are documented in the "SNVT" configuration document, which is supplied with the product and may also be ordered as a PDF document from the sales office. Unit To prevent fluctuations and changes in pressure from disturbing the commissioning work, it is important to lock the pressure regulation settings of the supply and extract air fans to a preliminary project-design value. If your system includes the KSM system manager, you can lock the fan pressures manually via the KOP hand-held micro terminal. Figure 3. Legend for the figure. 1. System manager KSM. 2. Supply and exhaust pressure sensor the the air handling unit. 3. The pressure regulators KZP or KZM for the supply systems. 4. Pressure sensor får the branch duct. 5. The pressure regulators KZP, KZM or slave regulator KSA for the exhaust systems. 6. Room regualtor KCD or KCW. Continuous operation after the commissioning In systems without the KSM system manager, select the pressure set point of the unit in such a way that the pre-defined target specified in the commissioning documents (usually between 70-100%) will, for the sake of simultaneity, provide the project-design max airflow. In systems with the KSM system manager, the max. and min. pressure set points can be set in the KOP hand-held micro terminal. Zone dampers In e.r.i.c. Systems with KZP/KZM for keeping the pressure constant in the branch ducts, these controls should be set to a suitable duct pressure, the default value is 50 Pa. It is very time consuming to calculate the optimal pressure if you do not have access to a CAD system that quickly and easily computes pressure settings for the whole system. As guidance, it is advisable to select a duct pressure that is as low as possible, but not lower than a value that provides a pressure of 20 Pa measured at the supply terminal connection. If the duct system is sized with little margin for change, the pressure must instead be selected with the max. airflow rate as reference. Select 80% as the max. permissible position in the supply terminals to seek out which pressure is needed in the duct system. Then increase or decrease the setting in the KZP/KZM until the correct airflow is obtained. 2 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com COMMISSIONING SEQUENCE 1. The unit Check and set the operation of the unit to a constant pressure. A suitable approximate value will be between 150-300 Pa depending on the size and character of the ventilation system. The pressure should be high enough to enable the unit manage operation at the max. airflow according to project design specifications. If the KSM system manager is included in the system, the unit pressures can be locked by means of the KOP hand-held micro terminal. This can be connected anywhere in the network and then makes it possible to simply increase the pressure if the zone dampers are fully open. Manual operation is described on page 33. 2. The zone dampers Set the pressure set point of the zone damper to a value between 30-50 Pa. Force at least 70% of all air terminals on the same branch duct to their max. positions (80% is the default). Check that the zone damper is controlled to the preset set point, read the airflow through the damper and compare the total flow with the current forcing airflow of the supply terminals. If the airflow deviates increase or decrease the pressure set point. Do not forget to change the dead zone for pressure regulation when the pressure set point is changed. This should be 10% of the pressure set point. In smaller systems, it is not common to use zone dampers. The air handling unit’s pressure regulation mode is instead used for keeping the pressure constant in the branch ducts. It is important that the pressure transducer of the unit be placed far out in the duct system at a representative place; see the Project Design Instructions for the e.r.i.c. System. 5. The slave airflow of the zone dampers The slave airflow values can be checked when you’ve finished adjusting the supply air. Normally, no adjustment should be made; the airflow setting is transferred from the master to the slave. If there are any offset airflow values, they can be set in the master if it has digital communication to the slave; and in the slave if it has an analogue connection from the master. A simple way to check whether transmission is digital or analogue is to see if a cord is connected to terminal 8 (Z1) on the KSA slave regulator, if this is the case, it has an analogue connection. 6. Documentation Record all the regulator setting changes on the ”Configuration data” form supplied with the product. If these forms are missing, you can order them from your nearest sales representative in the form of a PDF document. 7. Finishing Off Do not forget to reset all the temporary settings in each regulator. Settings of a temporary nature made in so-called “nvi” variables can be automatically set to 0 by briefly disconnecting the power supply. This could be a good alternative instead of going around having to adjust the regulator in every room. FUNCTIONAL CONTROL Separate functional control forms can be downloaded from our homepage on the Internet. The performance of each product should be tested individually and the findings should be recorded on the relevant page of the functional control document. Commissioning 2007-01 3. The air terminals Use the Coefficient of Performance (K-factor) Graph in these instructions for commissioning the supply terminals. Begin commissioning as soon as the zone damper (KZP or KZM) has reached its pressure set point, not sooner. Commissioning is done by setting the min/max positions of the motor-driven “damper”. No airflow measurement is carried out in the control process; instead it is assumed that the pressure in the duct system is regulated. This provides very stable control that does not have to compensate for pressure variations in the duct system. All the active supply terminals are equipped with measurement tappings and have a ”floating” coefficient of performance (K-factor). Set the min./max. positions in each type KCD, KCW or RTC room regulator. 4. KRF Room regulator This room regulator normally has totally pre-set values and does not have to be adjusted! 3 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com KZPb ---------------------------------------------------------KZPb SYSTEM VARIANTS KZP is intended for pressure regulation of branch ducts. For a detailed description of the regulators function see the regulator KCP in the handbook that describes all the e.r.i.c. regulators and their functions, which is available to download as pdf-file from our website. PUT INTO OPERATION KZP is always factory set with data for its functions. As soon as the 24 VAC is connected the KZP is in operation, and no additional work is called for. COMMISSIONING Setting of the pressure set point is done with the variable no 23 nciSetptPress. Set the value which you require between 10-300 Pa. The value for the dead zone 30 nciPressDzone should be set to 10% of the pressure setting, a lower value might make the control instable. If the regulator is acting hysteric and does not stabilise the pressure, the actuator is moving back and fourth, you could try with halving the gain factor in 28 nciPressGain. Figure 1.

If 2 nvoAlarmStatus bit 1 = 1 then KZP cannot maintain the pressure set point value as set in 23 nciSetptPress. The reason for this can be that the fan pressure is not sufficient; the variable 7 nvoDampPressVal shall in this situation should show 100%. Always check 7 nvoDampPressVal if the setpoint pressure value cannot be reached. This will indicate whether there is something else in the system that is not working, a fully open damper indicates that the fan pressure is not sufficient, or the reverse, a virtually fully closed damper means that the fan pressure has been set unnecessarily high. In some cases the integrated PI regulator works too quickly bringing about large fluctuations in the pressure, which do not seem to stabilise. In order to correct this problem you can adjust the gain factor 28 nciPressGain to a lower value, try with values between 0.3 0.1. Even the 29 nciPressItime can be reduced to achieve a faster control; lowest recommended value is 20 sec. Great differences in the measured pressure values and read values can be due to the incorrect installation of the pressure sensor KSP, see the installation instruction for KSP. All SNVT-variables for KZP, also see Appendix A in the handbook. Highlighted variables are the signification for KZP with the regulator KCP.

For a detailed description of the regulatrs function see the regulator KCP in the handbook that describes all the e.r.i.c. regulators and their functions, which is available to download as pdf-file from our website. PUT INTO OPERATION KZM is always factory set with data for its functions. As soon as the 24 VAC is connected the KZM is in operation, and no additional work is called for. For the slave control to be working the products must be “bound” to each other if the LonNetwork is used for communication (if this is done in the factory it will be stated on the product label), or be connected analogue to the slave regulator KSA. The analogue connection is detected by two wires are connected to the plinth 6 (Z2). Figure 1. Legend for the figure. 1. Pressure regulator KZM 2. Slave controler KSA 3. Network cable LonTalk 4.

Below you can see alternative settings of the nciAppOptions for system erimix. The normal configuration for KZM always starts with a 1. Setting of the pressure set point is done with the variable no 23 nciSetptPress. Set the value which you require between 10-300 Pa. The value for the dead zone 30 nciPressDzone shall be set to 10% of the pressure setting, a lower value might make the control instable. Setting of nciFlowConst (k-factor) is needed for measuring the airflow, this is normally done in the factory. If the regulator is acting hysteric and does not stabilise the pressure, the actuator is moving back and fourth, you could try with halving the gain factor in 28 nciPressGain. KZMb ---------------------------------------------------------------- SLAVE CONTROL There are two methodes to slave control, analogue and digital. Setting the values for digital slave control of the KZMa is done with the variables, 18 nviOfsSlaveState which describse how the slave control shall be preformed, 19 nviOfstSlavePerc or 20 nviOfstSlaveFlow, were you can choose between an offset value from the supply/exhaust in l/s or %. Data setting for, 18 nviOfsSlaveState High = offset in l/s Low = offset in % For digital transfer one of these values has to be set even if the offset should not be calculated. Setting of the set point pressure value is done with the variable no 23 nciSetptPress. Set the value which you require between 10-300 Pa. The value for the dead zone 30 nciPressDzone shall be set to 10% of the pressure setting, a lower value might make the control instable. If the regulator is acting hysteric and does not stabilise the pressure, the actuator is moving back and fourth, you could try with halving the gain factor in 28 nciPressGain.

Great differences in the measured pressure values and read values can be due to the incorrect installation of the pressure sensor KSP, see the installation instruction for KSP. Other variables that has significance and which can be checked on the KZM is: 6 nvoBoxFlow (Measured airflow value in l/s) and 5 nvoSetptFlowSlave the setpoint value with the offset which is sent to the slave regulator KSA when the digital LonTalk communication is used. With analogue connection, all the settings are made in the slave regulator KSA. The variables in the KSA are 15 nviSetptFlowSlave (l/s). Make sure 33 nciFlowDzone is not less then 5% of the set point value. 8 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com All SNVT-variables for KZM, also see Appendix A in the handbook.

Interval 0.1 - 0.5 is recommended, where low values are for big duct sizes. The new KRFc regulator calculates the mean airflow signal value, thus FlowGain normally has a higher value than the older KRFa and KRFc models (0.005 – 0.1). 34 nciFlowItime is factory preset and should not be altered; the value should be 30 sec. 0 0 0 0 0 0 0 0 (B10) Extra cooling regulation step = 1 (B12) Save some nvi’er = 1 NOTE!

The analogue connection is detected by two wires are connected to the plinth 6 (Z2) and the offset slave airflow (Ofst) is then set in the KSA. 23 nciSetptPress, low=% offset of the exhaust airflow, high= offset of the exhaust airflow in l/s. 24 nviOfstSlavePerc give offset +/- in % 25 nviOfstSlaveFlow give offset in +/- in l/s. When CO2 controlling it might be necessary to change the values for the P-band regulation that handles the airflow control. See diagram below for the relation between CO2 Current - Airflow. 47 nciSpaceCO2Low shall normally represent the outdoor level, this value is normally between 340-500 ppm depending on location. 48 nciSpaceCO2High is the value where the regulator will put out max airflow. CHECKING THE CO2 -SENSOR Is simplest done by breathing on the sensor and read of the result in 9 nvoSpaceCO2. The regulator should at the same time increase the airflow. Normal values for fresh outdoor air is dependent on the location of the building, in the country side it can be as low as 340 ppm and in cities 500 ppm. Also check 46 nciCO2PerVolt, which normally shall be 200 when connected with Swegons sensor KSC. If the combined output OUT1(temperature + CO2-value) is used, 46 nciCo2PerVolt should be set on 100, 47 nciSpaceCO2Low=0 and 48 nciSpaceCO2High=1000.

Note that alarm code automatically resets to the value 0 as soon as the reason for the alarm has been corrected, there is no possibility to through the operation panel see a activity log over previous problems. If the regulator controls the damper actuator in to big steps with the result of unstable airflow, the following adjustments is requiered: 33 nciFlowGain reduced in steps by halving, this will slow down the control with smaller steps, interval 0,01 - 0.5 is recommended. 34 nciFlowItime can be reduced to get a quicker control, lowest recommended is 20 sec. 12 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com CHECKING THE AIRFLOW First check the airflow data to ensure that these are within reasonable limits, remember that the hand terminal only updates the values every 16th second. To positively drive the regulator towards max or min airflow is easiest done with the variable 16 nviSpace Temp, this value can be set to -327.19 to check min airflow and +327.17 to check the max airflow. Do not forget to reset the value to INVALID. 7 nvoBoxFlow (Measure airflow l/s) and 5 nvoSetptFlowSlave is the set point value with the offset that is sent to the slave regulator KSA when the digital LonTalk communication is used. With analogue connection is used all settings are made in the KSA. Equivalent settings in the KSA are 15 nviSetptFlowSlave (l/s). If the airflow data is outside the min or max airflow settings, check the damper positions. 11 nvoDampFlowVal, if this value is 30 - 80% this is indicating that the duct pressure is too low or too high. Corrected by reducing/increasing the duct pressure in the KZP or air handling unit. CHECKING THE CONTROL OF RADIATOR VALVE Check that 27 nciAppOptions is set for heating control. There is only one method of checking the valve control. First by setting 16 nviSpaceTemp to -327.19 to make sure the valve is opening and then +327.17 to check that the valve is closing. Do not forget to reset to INVALID. To check that the regulator has changed the outputs can be displayed in 2 nvoUnitStatus where hp shall show 100.00 at the same time as 56 nvoHeatOutput shall show 100%. The output Y1-M shall put out 10V DC, output V1-M shall put out 24 VAC. KRFc CHECK MIXING AIR REGULATION OR EXTRA COOLING STEP Check that 27 nciAppOptions is set for every function. Check in the same way as you do the radiator valve as described above. Use the same output. CHECKING THE PRESENCE CONTROL Connected analogue presence sensor is checked by reading the variable 13 nvoOccSensor which shall show Occupied when it is activated. If the function is not correct, check 27 nciAppOptions bit 0 (=1) and 8 (=0). If the function still is incorrect you can check the regulator by connection the input X2 and M. If 13 nvoOccSensor still shows Unoccupied the KCF regulator is faulty. The variable 1 nvoEffectOccup has a delayed disconnection of 20 min, this is adjustable with 58 nciBypassTime. The variable 13 nvoOccSensor changes the mode between Occupied and Unoccupied, while 1 nvoEffectOccup changes between Occupied and StandBye. In standby mode the regulator is operating with other set points for temperature, see more in the manual for the KOP. CHECKING THE WINDOW SWITCH Connected window switch blocks the function by closing heating and the airflow is set to 0 l/s. Check is done with the variable 2 nvoUnitStatus, which shows off when window is open or open switch. When controlling radiator there is a frost protection that will open the radiator valve when room temp go below 10 °C. 13 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com KRFc ----------------------------------------------------------------- All SNVT-variables for KRF, also see Appendix A in the handbook.

For detailed description of the regulators functions, see regulator KCP in the handbook which describes all e.r.i.c. regulators and their functions, available as downloadable pdffile on our website. PUT INTO OPERATION KSA is always configured from factory with the data for its function. As soon as 24 VAC has been connected the KSA is in operation, some bindings may have to be made if using digital data transfer. 21 nciAppOptions shall always be 01000000 000001000. For slave control of the KSA to work, it has to be either bound digitally to the KZM/KRF (if this is done in the factory it will be stated on the product label), or analogue connected to the master KZM/KRF. The analogue connection is noted by wires connected to plinth 8 (Z1). Regulation by means of the KCP regulator Version 1.16 If the regulator controls the actuator in to big steps, with the result of an instable airflow, the following variables can be adjusted: 31 nciFlowGain reduced in steps by halving the current value, this slows down the controls by smaller steps. Interval 0,005 – 0,5 is recommended. The larger sizes have a lower value. 32 nciFlowItime is factory preset and should not be altered; the value should be 30 sec. Regulation by means of the KCP regulator Version 1.17 or later This type of regulator calculates the mean flow signal value for 6 sec and therefore offers smoother regulation which requires other values than those presented above: 31 nciFlowGain is decreased step by step by halving the current value, this provides slower regulation in smaller steps, an interval of 0.01 – 0.7 is recommended. The larger sizes have a lower value. 32 nciFlowItime is factory set and should not be altered; the value should be 30 sec. FUNCTIONAL CONTROL Control of the controlling airflow is done through the variable 15 nviSetptFlowSlave: 1. With digital airflow control from the master unit, this variable changes to whatever the master is transmitting. 2. With analogue airflow control, this setting shall be set to INVALID. Checking the airflow can only be done in 6 nvoBoxFlow. Registered design. The company reserves the right to make design changes without prior notice. 16 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com KSAb COMMISSIONING Changing or checking the variable settings (SNVT) on site is easiest with the operations panel KOP. KOP is connected to KSA, see figure 1. The operation of the regulator is determined by the settings in the variable nciAppOptins (00000000 00000000) 16 bit, according to the table. KSA only has one setting though, but with different functionalities. 1. Digital transmitted of the slave airflow setting or constant airflow function When operating as constant flow regulator the variable 15 nviSetptFlowSlave shall be given the airflow set point in l/s. NB! The 13th character in nciAppOptions has to be entered after the set point has been entered. 21 nciAppOptions = 01000000 00001000. When the slave airflow set point is digital transmitted via the LON-network, the set point in the variable 15 nviSetptFlowSlave is automatically set and changes as the master airflow changes. 2. Analogue transmitting the slave airflow set point from the KZM/KRF. 15 nviSetptFlowSlave shall always be set INVALID. 21 nciAppOptions = 01000000 00001000. When transmitted analogue and having different size on slave and master, nviOfstSlavePerc must be set as follows: Master k-factor / Slave k-factor calculated to % Example: Master size 250 slave size 200 gives k-factors 40,0 / 26,5 = 1,51 set the offset to +51%. The regulators nviOfstSLaveState must in this case be set to Low. Figure 1. The components normal location within the duct system. 1. Pressure regulator KZM 2. Slave regulator KSA 3.

As soon as 24 VAC has been connected the KSA is in operation. A settings document is supplied with the KCD containing the customer specified variable settings in one column and the default values in another column. If the KCD is not configured the document will only contain the default settings. The regulators operation is determined by the setting in the variable nciAppOptions (00000000 00000000) 16 bits, as follows bellow. Controllermunctions as SNVT received by LonTalk does not require definition in nciAppOptions. During CO2 control you may need to adjust the setting for the P band of the airflow control. See the diagram with the relation CO2 ¡V Voltage - Airflow. 39 nciSpaceCO2Low shall normally correspond with the level in the supply air, this value should be 340-500 ppm for full fresh air systems depending on the outdoor conditions. 40 nciSpaceCO2High is the level where the regulator gives max airflow rate. COMMISSIONING The customer specified factory settings are found on the settings document (SNVT). For additional information of how the variables operates under different operation modes, see the regulators handbook. Setting of "Airflows" diffuser/damper positions Setting the airflow can not be done just by entering the airflow as l/s. It must be done by damper position in proportion with the duct pressure. The following values can be set in the regulator: 32 nciMinPosn min supply airflow during occupied mode 33 nciMaxPosn max supply airflow during occupied mode 34 nciMinPosnHeat min supply airflow during heating mode 35 nciMinPosnStand min supply airflow during heating mode 48 nciMinPosnExh min exhaust airflow during occupied mode 49 nciMaxPosnExh max exhaust airflow during occupied mode 50 nciMinPosnStdExh min exhaust airflow during unoccupied mode With the commissioning graph and the measured pressure on the active diffusers measuring point the airflow is found in the graph or calculated. Checking the C02 -SENSOR Is simply done by breathing on the sensor and read of the result in 7 nvoSpaceCO2. The regulator should at the same time increase the airflow. Normal values for fresh outdoor air is dependent on the location of the building, in the country side it can be as low as 340 ppm and in cities 500 ppm. Also check 38 nciCO2PerVolt, which normally shall be 200 when connected with Swegons sensor KSC. If the combined output OUT1 (temperature+CO2 -value) is used 38 nciCo2PerVolt should be set on 100, 39 nciSpaceCO2Low=0 and 40 nciSpaceCO2High=1000. 20 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com FUNCTIONAL CONTROL Use the hand terminal KOP to read the status of the regulator in the form of alarm codes and current values. Table Bit 0 1 2 3 Value 0 1 0 1 0 1 0 1 Problem Non Deviating room temperature Non Low room temperature Non Window switch alarm Non Too high C02 -level CHECKING THE PRESENCE CONTROL Connected analogue presence sensor is checked by reading the variable 10 nvoOccSensor which shall show Occupied when it is activated. If the function is not correct, check 21 nciAppOptions bit 0 (=1) and 8 (=0). If the function still is incorrect you can check the regulator by connection the input X2 and M. If 10 nvoOccSensor still shows Unoccupied the KCF regulator is faulty. The variable 1 nvoEffectOccup has a delayed disconnection of 20 min, this is adjustable with 36 nciBypassTime. The variable 10 nvoOccSensor changes the mode between Occupied and Unoccupied, while 1 nvoEffectOccup changes between Occupied and StandBye. In standby mode the regulator is operating with other set points for the temperature control, see more in the manual for the KOP. Whether or not the value is 1 in other positions (4-11) is of no importance for the regulation function of the regulator. There is more to read about the alarm codes and their limit values in the handbook. Take into consideration that the alarm codes are automatically reset to the 0 value as soon as the cause of the alarm has been remedied. It is therefore not possible to directly see any log of events disclosing earlier problems via the operator panel. CHECKING THE AIRFLOW Checks can only be carried out by forcing the regulator to the max. and min. positions respectively and in these positions check the pressure in the supply air terminal. See the Commissioning Instructions for each type of supply air terminal. Forced control of the regulator towards max. or min. airflow is best done with the variable 13 nviSpaceTemp, this value can be set to -327.19 to check min. airflow and +327.17 to check the max. airflow. Do not forget to reset the value to INVALID. KCDb CHECKING THE RADIATOR VALVE CONTROL Check that 21 nciAppOptions is set for heating control, bit 2 and 3. There are two outputs for radiator valves, one is 010V for actuator control (Y1) which only can be used when the regulator is configured with bit 3=0 and one for thermo actuator (V1) which is used when bit 3=1. There is only one method of checking the valve control. First by setting 13 nviSpaceTemp to -327.19 to make sure the valve is opening and then +327.17 to check that the valve is closing. Do not forget to reset to INVALID. To check that the regulator has changed the outputs can be displayed in 2 nvoUnitStatus where hp shall show 100.00 at the same time as 51 nvoHeatOutput shall show 100%. The output Y1-M shall put out 10V DC and output V1-M shall put out 24 VAC. If and how different makes of actuators respond differs. For Siemens I=closed and 0=open valve. CHECKING THE WINDOW SWITCH Connected window switch blocks the function by closing heating and the airflow is set to 0 l/s. Check is done with the variable 2 nvoUnitStatus, which shows off when window is open or the switch is open. When controlling radiator there is a frost protection function that will open the radiator valve when the room temperature goes below 10 °C. 21 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com KCDb ---------------------------------------------------------------- All SNVT-variables for KCD, also see the Appendix A in the handbook.

For detailed description of the regulators functions, see regulator KCW in the handbook, which describes all e.r.i.c. regulators and their functions, available as downloadable pdf-file on our website. PUT INTO OPERATION Connection The regulators operation is determined by the setting in the variable 25 nciAppOptions (00000000 00000000) 16 bits, as follows bellow. COMMISSIONING Setting of "airflows" diffuser/damper positions Setting the airflow cannot be done just by entering the airflow in l/s. It must be done by damper position in proportion with the duct pressure. The following values can be set in the regulator: 38 nciMinPosn min. supply airflow during occupied mode 39 nciMaxPosn max. supply airflow during occupied mode 40 nciMinPosnHeat min. supply airflow during heating mode 41 nciMinPosnStand min. supply airflow during heating mode With CO2 control you might have to change the setting for the P band controlling the airflow. See graph for the relation between CO2 – Current - Airflow. 43 nciSpaceCO2Low shall normally represent outdoor conditions; this value is normally 340-500 ppm depending on the location. 44 nciSpaceCO2High is the value where the regulator shall give max airflow. The function of the valve actuator outputs When the regulator is configured for increase/ decrease valve control, V1 opens and V2 closes the cooling valve and V3 opens and V4 closes the heating valve. When the regulator is configured for thermo actuators the current on the outputs V1-V4 are according to the table, which shows how the thermo actuators opens and closes during different modes. The heating valve must be of the type powerless closed, and the cooling valve can be either type but the wiring is dependent on the function. nciValve Override Open Close V1 V2 Cooling valve 24VAC 0 0 24VAC V3 V4 Heating valve 24VAC 24VAC 0 0 FUNCTIONAL CONTROL Use the hand terminal KOP to read off the status of the regulator in forms of alarm codes and current values.

By setting the variable 21 nciManOverride to Position and the value to 100%, the damper should open fully. Do not forget to reset the variable to position Off. The valve actuators are checked by setting 24 nciValveOverride to position Open and Close, to test the actuators directions. Do not forget to reset the variable to position Off. KCWa ---------------------------------------------------------------- CHECKING THE COOLING SEQUENCE To force control the regulator towards max or min airflow is done with the variable 16 nviSpaceTemp, it is set to +327,17 to check the max airflow for cooling. Do not forget to reset the variable to INVALID. The cooling valve should open first, can be checked by monitoring the variable 9 nvoCoolOutput which shall display 100%, then, if active diffusers are used, shall the damper open to the value set in the variable 39 nviMaxPosn, which is checked through 11 nvoDampFlowVal. If the actuator does not move it could be faulty wiring, cut wires or defect actuator/valve. The cooling sequence could be reversed so that the diffuser opens first and then the cooling valve. Reset 13 nviSpaceTemp to INVALID after check. CHECKING THE HEATING SEQUENCE Force the regulator by changing 13 nviSpaceTemp to 327,19 to check the min airflow and heating mode. First the heating valve shall open, which can be check through variable 8 nvoHeatOutput, which shall display 100%. If the actuator does not move it could be faulty wiring, cut wires or defect actuator/valve. Reset 13 nviSpaceTemp to INVALID after check. CHECKING THE C02 -SENSOR The CO2 function is only active when the regulator is in the cooling mode. Check the function simply by exhaling air towards the sensor and reading the result in the 7 nvoSpaceCO2. variable. The regulator should now increase the airflow at the same time. The normal value for fresh outdoor air depends on where the plant is geographically situated. A value for fresh air in the countryside is 340 ppm, whereas a city air can contain 500 ppm. Also check 42 nciCo2PerVolt, which normally should be 200 connected to Swegon’s KSC sensor. If the combined output, OUT1 (temperature + CO2 value) is used, the 42 nciCo2PerVolt should be set to 100, 43 nciSpaceCO2Low=0 and 44 nciSpaceCO2High=1000. CHECKING THE OCCUPANCY SENSOR The occupancy sensor KSO has a red diode that is light behind the front when activated. On the room unit KST, the red diode shall be lit when the occupancy sensor activates operation mode Occupied. The system disconnect after 20 minutes, which is a fixed setting in the KCW regulator. In the KSO there is possibilities to set the disconnection time for both on and off. 26 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com All SNVT-variables for KCW, also see the Appendix A in the handbook No Description Normal value Explanation with reference to regulator KCP-KCF-KCD-KCW Handbook Occupied Any marking max 32 characters entered on the regulator using e.g. LoneMaker for Windows.

When used in the e.r.i.c. System, the output for heating can be reprogrammed to become an output for cooling with separate min./max. settings for an extract air terminal, for example. If the need arises to alter settings, this must be done via the LUNAb T-CU hand terminal. To save on energy, an occupant detection sensor can be connected to the RTC, which then will have a larger dead zone between heating and cooling. RTC be in used to BLB mixing box. PUT INTO OPERATION On delivery, the RTC is fitted with jumpers for a 0-10V DC signal on the outputs for heating and cooling. It may become necessary to refit the jumpers for on/off switching, if that type radiator actuator is used. See the jumper positions in Figures 2 and 3. When the jumpers for the output for heating are refitted, the function of the output has to also be changed using the handheld micro terminal to convert the regulator to an on/off-regulator. Read more below Commissioning. The RTC has one LED that indicates the current operational status: 1. Green: Cooling load 2. Red: Heating load 3. Not lit: Neutral position - no output signal Figure 1.

More information about these is available in a separate manual for the LUNA T-CU. RTCb ----------------------------------------------------------------- COMMISSIONING The min./max. positions for the active air terminals in the e.r.i.c. System can be programmed with the LUNAb T-CU hand terminal. The output values to be set are the voltage limits: LIMH V (upper limit) and LIML V (lower limit). The menu structure is built-up into several levels, where you move to the next level by pressing SELECT and with SET select the sublevel where you advance and go back with the BLUE and RED arrow keys respectively. Start by reading the settings already in the RTC. Press "READ" (LÄS), set the new values and finally press "WRITE" (SKRIV) for approx. 3 sec. All set values remain in the hand terminal and can be written into the next regulator, simply by using "WRITE" (SKRIV). press on the key, you can recover all the default values by briefly isolating the power supply and then hold the key down for 5 seconds after the power is restored. The functions of the key: 1. Calibration of internal and external temperature sensors 2. Resetting the memory of the regulator 3. Inverting the output signals on all the heating steps. Set min/max positions for the active air terminals To change the min. and max. settings, press SELECT until OUTP.(UTG) is shown. Press SET and select OUTP. (UTG) 4 with the BLUE arrow, acknowledge with SET. Then select the output to be altered with the blue arrow: A1 (normal supply air) or A2 (normal extract air). Then press the BLUE arrow to the desired limit: LIML and LIMH. To alter the voltage value, press SET and alter with the BLUE/RED arrow. This output must be reset to cooling (the output for heating is the default) if output A2 is used for extract air terminals. Select OUT.no. A2 (UT. Nr A2), press the blue arrow to VK:HHEAT and change to COOL. Press the blue arrow and change the type On/Off to 0-10V. See Figure 4. Save the settings in the room regulator by pressing WRITE (SKRIV) until the display shows PRO!...0. To change output A2 to on/off regulation for heating Change the position of the jumpers as shown in the figure on the preceding page. Advance to OUTP. (UTG.) Menu 4, select OUT. no. A2 (UT. Nr A2), press the blue arrow to TYPE (TYP), press SET and alter the type to On/Off with the blue arrow, confirm with SET. To set the delay for the presence function Normally the parameters of the regulator do not need to be changed if an occupant detection sensor is connected. The occupant detection sensor should be connected via the NC contact function (NC= no occupants). Set the switch-in delay directly in the KSO; set the switch-out delay in the RTC. The default is 60 min. To alter the switch-out delay, press SELECT until OUTP. (UTG) is shown. Then press SET and select PRESENCE 6 (NÄRVARO 6) with the BLUE arrow, acknowledge with SET. Then select TIME 0 (TID 0), press SET and change with the blue/red arrow and acknowledge with SET. The switch-in delay can also be set at the TIME 1 (TID 1 ) parameter. For more detailed information about all the functions, see the separate manual: 3 LUNAb T-CU Hand terminal. Figure 4. Menu Structure.

If you should inadvertently 30 Swegon Commissioning System e.r.i.c. 1-2207 www.swegon.com KSMb -------------------------------------------------------KSMb SYSTEM VARIANTS The system manager KSM is only available in one execution for optimising the fan operation. The control of the air handling unit’s pressure control is done through LonTalk communication between the KSM and the AHU’s Lon module. PREPARATION WORK The system manager has default values which make the start up procedure fast, only a limited number of variables has to be set for the customised operation. Additional information can be found in the commissioning guide. FUNCTIONAL CONTROL The control s preformed with the help of the hand terminal KOP. It connects onto the system manager. If a Lon network is present connecting all units you can access the system manager from the room unit KST. In this case you may have to reset the Lon address, menu 4, to connect with the same 1byteID = 11 as the network was setup with. Normally this value shall be 11. The settings in menu 10 shall be: Xenta100:ON and MOD:MAN. These values are set once for all e.r.i.c. components. OPERATIONAL STATUS Operating mode – applicable to output data only (u) Unit operation: If =1 is shown, the unit is operating. Control is permissible, delayed: 1 = control is permissible. This value becomes 1 after the period which is preset in the starting delay. MEASURED VALUES Measured values TF/FF Pressure readings in the unit as well as the positions of the dampers connected (0-100%, 100%=fully open) are indicated as percentages and in Pa. Check the positions of the dampers; they should be within the preset limits. It may happen that one of the dampers becomes controlling because it needs more pressure than all the others. This directs the controls to prevent the dampers from being fully open. If any dampers need to be fully open, the appropriate setting in the controls must be changed to allow higher pressure. If any damper indicates 0%, no link has been established or else the damper has been forced to close at 0%. Keep in mind that there are values for dampers which are not bound! If a damper value shows 166% this indicates that the regulator in question is in a default state. Check the relevant regulator for remedial measures. Alarm Here you can see if any control parameters has not achieved their values within the time set in the alarm delay. Alarms are reset using the ENTER key on KOP. You can also find alarm from connected dampers. A 1 indicate an alarm, the damper has not achieved its max value within the time set in the alarm delay.

Figure 1. KSMb ---------------------------------------------------------------- COMMISSIONING For optimal operation of the system manager a few parameters must be set, those are marked with * . The system manager optimises the operation of the AHU even if these parameters are not set, but then only towards four dampers. The figure on the right shows the menu structure in the system manager. To change parameters the KSM has to be bound with LonMaker to the branch duct dampers and the AHUs Lon-module. Then connect the hand terminal KOP to the socket on the front of the KSM, do not press OK when the question is displayed, and wait for the direct connection with KSM. KOP must in the OP-menu 10 be set to Xenta 100 : ON and Mode : MAN. In menu 4, the 1byte-ID must be set to the same value as the network was setup with, normally 11. A commissioning protocol for KSM as an excel-file is available on our website. Parameter settings 1. Check the pressure range on the AHUs pressure sensors. 2.

SetPt Pressure TF/FF • SetPt Pressure Start: Satart set point in % (default 30%) • SetPt Pressure Min.: Lowest allowed pressure in % (defalut 10%) • SetPt Pressure Max.: Highest allowed pressure in % (default 90%) Damper values • Increase SetPt TF/FF: At this damper position (85%) KSM increases the pressure set point on the AHUs supply fan. • Increase SetPt TF/FF: At this damper position (70%) KSM decreases the pressure set point on the AHUs supply fan. MANUAL Manual operation TF/FF. This function is only used during the commissioning phase if you wish to fix the duct pressure. Manual 1=%. 2=Pa: Setting if input data shall be in Pa or %. SetPt TF %: If previous value is set to 1 this is the manual value in %. SetPt TF Pa: If first value is 2 this is the manual value in Pa. PASSWORD State a password to be able to procced (1919). Start delay • Control delay on start: Setting of the time (sec) before KSM start to control after sending the start pressure set points. Default is 1800 sec, can be reduced but not less then 600 sec. Pressure range • Pressure range Pa: Setting of what max output signal from the pressure sensor (10V or 100%) represents in Pa. This value is only used to be able to present real values in the KOP, default value is 500. CONTROL PARAMETERS These values are adapted to the unit control parameters. Control 1time: Default=120 sec. This value should be set equal to the I-time set in the AHU pressure control. Velocity constant: Default=1.0 This value is a gain factor depending on the numer of branch duct dampers connected. Value can be adjusted between 0.12. RampVelocity: Default=2%/min. This value effects the speed of how fast the KSM reduces the pressure set point value so that the dampers opens more. Value 1-20 %/minute. If the reduction is slow, dubble the current value, if it is too quick the system can start to hunt. OTHER PARAMETERS Alarm delay TF / FF MaxAchieved TF (FF): Time in seconds until an alarm shall be sent that KSM has achieved its highest allowed pressure set point for the supply fan. Pressure response TF(FF): Time in seconds until an alarm shall be sent that KSM has achieved its highest allowed pressure set point for the exhaust fan. 33 Swegon Commissioning System e.r.i.c. 1-2007 www.swegon.com KSMb DATE AND TIME Set or change the built in clock. The time is only used for register when an alarm occured. CONTROL FUNCTIONS Controlling TF/FF • Delay next package: KSM controls the pressure by sending out “pressure packages”. The time between these packages is set here (default is 1200 sec). High values gives slow control. Lowest recommended value is 300 sec. • Package size: Setting of the package size in %. The size is dependent of the interval of the pressure sensor (0-100%) that KSM shall work within. Example: If the pressure sensor range is 0-3000 Pa, then maybe the KSM shall work within the interval 0-20% that means the package size should be smal (0.5%). Default value is 10%. • Number ducts: Number of ducts/dampers which are bound to the KSM on supply and exhaust side, default value is 4. • Pressure response from AHU: KSM always wait to send out the next pressure set point until the AHU has achieved the current set point. % allowed offset from set point value, before a new set point value may be sent from the KSM, default value is 2%. ERIMIX ----------------------------------------------------ERIMIX BASIC PRINCIPLES Erimix system E1 The KZP or KZM set with nciAppOptions B2=1 and B3=0 provides the complete erimix operation with the KCD room regulators controlling the mixing air temperature. The KCD is bound via the network to the KZP/KZM regulator. Here, the KZP or KZM controls the mixing box BLB. Important settings for the E1 System: In the KZP/KZM that controls the mixing air temperature, set the parameter 43 nciNumCoolCase to the number of room regulators that shall dominate the switch between cooling mode/heating mode. An appropriate number could be 70% of the number of KCD units bound to the KZP/KZM. ERIMIX system E2. The KZM set with nciAppOptions B2=0 and B3=1 provides the complete erimix operation with the KCD room regulators controlling the mixing air temperature, and the KSA controlling on the extract airflow. The KCD is bound via the network to the KZP/KZM regulator. Here, the KZP or KZM controls the BLB mixing box. The KSA is a slave controlled by the KZM. Important settings for the E2 System: In the KZP/KZM that controls the mixing air temperature, set the parameter 43 nciNumCoolCase to the number of room regulators that shall dominate the switch between cooling mode/heating mode. An appropriate number could be 70% of the number of KCD units bound to the KZP/KZM. Figure 1. Flow chart for the E1 Erimix System. ERIMIX Figure 2. Flow chart for the E2 Erimix System.

Here, the KZM controls the BLB mixing box. The KSA as a slave controls the extract airflow to the KZM; the KSA in turn transmits the extract air temperature to the KZM. Temperature settings for Systems E1-E3 The supply air temperature is set in the variables in accordance with the following: The heat level in 21 nciSetpoints and the upper limit in 45 nciDuctTempMax; the cooling level in 21 nciSetpoints and the lower limit in 44 nciDuctTempMin. Default values for the regulation ranges are 13-19 °C cooling temperature and 24- 28 °C heating temperature. The dead zone will then be 5 °C. ERIMIX System E4 Refers to the KRF room regulator that in this case controls the BLB mixing box. The position of the mixing box is read via variable 8, nvoTerminalLoad, where -100% denotes the max. heating level and 100% denotes the max. cooling level. 0% is then the intermediate level. Observe that the damper motor of the mixing box must be set to a 0-10V operating range. For more information about other functions, see the KRF. Figure 3. Flow chart for the Erimix System E3.
