Introduction This section provides a description of the NETstatTM Z-2400 Zoning Thermostat from Jackson Systems. It also introduces safety information. Review this material before installing or operating the thermostat. The NETstat Z-2400 Zoning Thermostat is a space mounted device that wires to an actuator-driven VAV diffuser or damper. The thermostat uses a P+I (Proportional + Integral) control algorithm to modulate a diffuser or damper using a 24 volt AC floating-point actuator. The thermostat is designed to be used as a stand-alone, pressure independent VAV diffuser or damper controller. The NETstat Z-2400 Zoning Thermostat is a native BACnet®, Application Specific Controller. BACnet communication parameters, device instance, MAC address, baud rate, user adjustments and application configuration values are accessible from the thermostat or BACnet front end. A two-piece mechanical design featuring a removable backplate facilitates easy wiring and installation.

Installation Thermostat Location • The thermostat should be located on an inside wall in the zone being served by its diffuser or damper. • Do not install the thermostat in an area where drafts are present, near the floor, behind doors or on an external wall. • Avoid installing the thermostat in areas where the air movement is limited, affected by direct sunlight or other areas not typical of the temperature of the zoned space. • When mounting the thermostat, be aware that drafts may travel down cavity walls and enter the back of the thermostat through the control wire holes in the wall. It is important to seal these holes to prevent any drafts from affecting the internal temperature sensor. • When used in a stand-alone zoning application, the thermostat should never be installed in the same area where the equipment thermostat is located. Rough-in Preparation • Complete rough-in wiring at each thermostat location before installing the thermostat mounting base. • Route the connecting cable or cables from the thermostat location to the actuator board located on the side of the diffuser or damper actuator. • If required, install an appropriate wall plate kit. Installing the thermostat mounting base • Locate the Allen screw on the bottom of the thermostat and turn it clockwise until it clears the mounting base. • Swing the thermostat away from the mounting base to remove it. • Position the base with the embossed UP toward the ceiling and fasten it directly to a vertical 2 x 4 inch electrical box. For horizontal boxes or 4 x 4 applications, use a wall plate kit.
!
To prevent mounting screw heads from touching the thermostat circuit board, use only the mounting screws supplied with the thermostat. Using screws other than the type supplied may damage the thermostat.
Caution
Thermostat Wiring • Refer to the system wiring diagram on the next page. • Each input on the thermostat is configured for a specific function and does not require set-up in the field. • Not all inputs are required and are so noted on the thermostat terminal label as Not Used. • Pull the control wires through the large opening in the thermostat mounting base. • Use a properly sized screwdriver and land each wire to its dedicated terminal. • Do not over-tighten the terminal block screws. • Check to see that all wires are landed properly to prevent any shorts circuits or missing wires.
!
Caution
To prevent electrical short circuits which could potentially damage system components and/or the transformer, make sure that 24 volt power is disrupted during wiring.

Installing the Thermostat • Once all system wiring is completed, place the top of the thermostat over the top of the mounting base and swing it down over the Allen screw bracket. • Turn the Allen screw counterclockwise until it backs out of the mounting base and engages the case. • Confirm that the thermostat is properly seated to the mounting base and secured by the Allen screw.
System power-up • Apply 24 volt power to the Actuator Board on terminals R and C. • Confirm that the 24V Power LED on the Actuator Board is lit. • Confirm that the thermostat display is lit. • When power is first applied to the thermostat, it will initiate a synchronization process with the damper actuator. This takes approximately 2 minutes. • Once the synchronization process is completed, the thermostat will resume normal operation.

Accessing Thermostat Functions The thermostat functions can be accessed through a user interface consisting of simple, context sensitive menus. The menus are opened and options are selected by using the buttons and a color display on the front of the thermostat. • Pressing either the UP or DOWN button changes a selection, setting or value. • Pressing the Enter button saves the selected setting or value. Typically the Enter button is the middle of the three Soft Key buttons. • Saving a selection also advances to the next menu step. • The three Soft Key buttons are defined by labels on the soft key bar. • Back - Returns to the previous menu • Cncl - Cancels current changes • Done - Push this button at any point while entering a value. For example, if you have entered the first two digits of a password and the remaining two digits are correct, pushing Done completes the entry of the password. • Enter - Pushing this button enters the selection and advances to the next step • Exit - Returns to temperature display
Commissioning functions Commissioning functions are values and settings that are entered during the installation and commissioning of the thermostat. Typically these functions do not change after the installation and commissioning process.
Entering the Commission Mode The thermostat is not password protected when shipped from the factory. After commissioning, it is highly recommended that a password be entered in the advanced commissioning function (Password 2) to prevent user access to these parameters. 1. With the thermostat powered and displaying the space temperature, simultaneously press and hold the left and right Soft Key buttons until the MAIN menu appears.
