Page 8: Linkage
Introduction Linkage The i-Vu Open Control System uses linkage to exchange data between the zone terminals and their air source to form a coordinated HVAC system. The system's air source controller and zone controllers are linked so that their data exchange can be managed by one zone controller configured as the VAV Master. A VAV Master can have a maximum of 63 slave zone controllers reporting to it.

Installation Wiring the VAV Zone Controller to the MS/TP network The VAV Zone Controller communicates using BACnet on an MS/TP network segment communications at 9600 bps, 19.2 kbps, 38.4 kbps, or 76.8 kbps. Wire the controllers on an MS/TP network segment in a daisy-chain configuration. Install a BT485 on the first and last controller on a network segment to add bias and prevent signal distortions due to echoing.

Page 40: Commissioning The Vav Zone Controller
Start-up Verify that zone terminal fans and system controls operate properly. Verify that actuator screws are properly tightened. At the zone terminals, check electrical system and connections of any optional electric reheat coil. If hot water reheat is used, check piping and valves against job drawings. Verify that all zone terminal dampers are fully open.
Page 41: Balancing The System
Start-up Balancing the system Most VAV system airflow designs are based on cooling requirements which require a greater cfm (liters/second) flow than heating requirements. Using the following balancing procedure, you adjust the cooling airflow first. If the heating and cooling maximum airflow requirements are the same, you do not need to balance the heating airflow. Use the Test &...
Page 42: Sequence Of Operation
Sequence of operation Sequence of operation The VAV Zone Controller supports 3 types of pressure-independent terminal configurations: • Single duct • Series fan-powered • Parallel fan-powered The controller can operate as part of a linked system (VAV or VVT) or as a stand-alone controller. Temperature sensors The VAV Zone Controller supports the following temperature sensors: Sensors...
Page 43: Zone Reheat Control
Sequence of operation Single duct with reheat – The Auxiliary Heat Min Airflow allows an increase of primary airflow across the terminal’s ducted heating coil whenever the terminal operates its local heat. This provides the ability to lower the cooling minimum airflow limits while providing the necessary airflow when the terminal is heating to ensure design load conditions and electric heater minimum airflow.
Page 44: Demand Control Ventilation (Dcv) And Dehumidification Using Optional Sensors
Sequence of operation Two-Position Hot Water / Steam Heating Heat – The controller operates a normally closed or normally open hot water or steam valve connected to the discharge air heating coil. The valve opens and closes as needed to satisfy the zone's heating requirements.
Page 45: Occupancy
Sequence of operation NOTE If the connected sensor and/or system sensor value are to be used by the air source through Linkage, set the appropriate control type to Enable. If you do not need local control at the zone, set DCV Max Vent Airflow or Maximum RH Override Airflow to 0.
Page 46: Alarms
Sequence of operation Remote Occupancy Override – The controller monitors its Remote input that is typically connected to the isolated, dry contact of an occupancy sensor located in the zone. (To use the occupancy override as described here, the Standby Offset value must be set to zero.) The controller can override the occupancy state based on whether or not the space is actually occupied.
Page 47: Demand Limiting
Sequence of operation Space Relative Humidity Alarm – If Optional Ctrl Type is set to RH Control (Space Relative Humidity (RH) sensor is installed), the controller generates an alarm if the sensor's value exceeds the Occ High RH Alarm Limit (100% rh default) or the Unocc High RH Alarm Limit (100% rh default).
Page 48 Sequence of operation The basic linkage process is as follows: The Master gathers data from the slave zone controllers such as occupancy status, setpoints, and zone temperature. The Master performs mathematical calculations and algorithms on the data. The Master sends the composite information to the air source. The air source returns information such as mode, supply air temperature, and outside air temperature, if present.
Page 49 Sequence of operation VVT Systems A VVT Master determines system operation by prioritizing heating and cooling requirements from all the zones based on their occupancy, demand, and damper size. The VVT Master continuously scans the system to determine if any zones are occupied. If any zones are occupied, the VVT Master evaluates the occupied zones' heating or cooling demands to determine the following: •...
Page 50: Air Source Mode Determination
Sequence of operation Air source mode determination Linked air source modes – In a linked system, the air source determines its operating mode and qualifies that mode based on its own SAT. The following modes can be sent by the air source depending on its capability and configuration: •...
Page 51 Sequence of operation Metric: Use manufacturer’s liters/second at .249 kpa NOTE A local air source fan mode of OFF usually cannot be detected on series fan boxes. This is because the terminal’s series fan, when operating with the terminal damper open, usually creates enough primary airflow to prevent the control from properly detecting that the air source is off.
