It contains all common functions to control and monitor air conditioning in 4 zones and 4 associated fans. The following diagram provides an overview: Detailed information Contact Fläkt Woods support for a detailed description of standard application eq zon v1.x. Network variables The set of loadable files mentioned above also includes a mapping file for integration in a higher building automation and control system via communications module. The Climatix controller automatically assumes the network variables required for integration as per the plant data points and functions configured and parameterized previously.

Network variables 3.1 Overview Contents of LON image set AHU V1.x The LON module's Neuron application supports 62 network variables to integrate controllers with air handling applications in a management station, and allow controllers to exchange data over LON. The figure shows the variables for LON image set (XIF) POLXXX_Std_AHU_V100 (ClimatixAHU V1.x) and their SNVTs, grouped as follows: Mandatory network variables (A) Optional network variables (B) Configuration parameters (C) nvirequest SNVT_obj_request A nvostatus SNVT_obj_status P3931Z10 nvitemps SNVT_temp_setpt B nvotemps SNVT_temp_setpt nvotemp01 nvotemp02 nvitemp01 nvotemp03 nvotemp04 nvotemp05 nvitemp02 nvotemp06 nvotemp07 nvotemp08 nvihum00 SNVT_abs_humid nvohum00 SNVT_abs_humid nvohum01 SNVT_abs_humid nvihum01 SNVT_abs_humid nvoflow00 SNVT_flow nvoflow01 SNVT_flow nvippm00 nvoppm00 nvipress_flow00 nvopress00 SNVT_press_p nvopress01 SNVT_press_p nvopress02 SNVT_press_p nvipress_flow01 nvipress_flow02 nvipress_flow03 Neuron Application AHU V1.x nvopress_flow00 nvoperc00 nvoperc03 nvopress_flow01 nvoperc01 nvoperc04 nvoperc02 nvoperc05 nvipress_flow04 nvoperc06 nvoperc07 nvoperc08 nvipress_flow05 nvoperc09 nvoperc10 nvoperc11 nviresetalarm SNVT_switch nvoperc12 nvoperc13 nvoperc14 nviopmode SNVT_switch nvoopmode SNVT_switch nvicontrol SNVT_state nvoswitch00 SNVT_switch nviacttime SNVT_time_stamp nvostate SNVT_state_64 nvodo SNVT_state_64 nvodi SNVT_state_64 nvoalarm SNVT_state_64 ncimaxsndtime SNVT_time:sec C ncimaxrcvtime SNVT_time_sec ncistartupdelay SNVT_time_sec The sections below describe the network variables. 5

6 3.2 General Purpose SNVT handling The following sections describe the network variables used in the specific application and LON image (XIF), see Section 1.2 "Before you start". Pay attention to the following explanations concerning some specific characteristics of SNVTs and elements used: SNVT / Element Explanation Heartbeat All output (nvo) SNVTs send heartbeat. No SNVTs requires heartbeat from the network. All input (nvi) SNVTs write back changed values, from the controller, to the Neuron, means that a setpoint could be set from both the controller and the network, depending on BMS system. Min Send time Some output (nvo) SNVTs use the "Min send time". Means that this SNVT have fastest send interval of x seconds. SNVT_state Climatix are using SNVT_state binary counted from left to right and due to that some LON devices counts from right. In this case it is necessary to invert the bits, Bit0=Bit15, Bit1=Bit14... SNVT_switch The state part for SNVT_switch must be set to 1 (Active) to use the value part. SNVT_temp_setpt The SNVT_temp_setpt is used for different temperature set points and to show the actual set points, and it could be different set points than named within the SNVT due to these names are fixed. Example is the first value "occupied cool" used for Basic heating set point instead. See further in this document. Override I/Os Inputs that are possible to override via LON is marked with (I/O), theese must first be setup to be overridden via communication, see Integration guide. SNVT info The following tables briefly describe each variable used and it's SNVT. Thereby the "NV index" presents the network variable number in the XIF file (LON image). Refer to 4.1 "Description of SNVTs" for more information on the SNVTs. In the configuration mode it s possible to activate Zone 1 Zone 4 and Fan 1 4 in the same regulator. But the LON network variables are only 63 / regulator. This means that it s only possible to control 2 Zones or 2 Fans in 1 regulator. If there is a need to have 3 or 4 zones/fans it only possible with 2 regulators. Ex. Regulator 1 Zone 1 2, Fan 1 2 Regulator 2 Zone 3 4, Fan 3 4 Zone 1 and 3 use the same network variables. Fan 1 and 3 use the same network variables. Zone 2 and 4 use the same network variables. Fan 2 and 4 use the same network variables. 6

They are needed for system purposes: The two variables are: nvirequest nvostatus Requires a particular mode for a specific object in a device. nvirequest Object request SNVT_obj_request NV index: 0 Output variable nvostatus Signals the status of the requested object in the device. nvostatus Object status SNVT_obj_status NV index: 1 7
