I NSTALLATION Remove the security screw on the bottom of Terminal Equipment Controller cover. Open unit by pulling on the bottom side of Terminal Equipment Controller (fig. 1). Remove wiring terminals from sticker. Please read the FCC ID and IC label installed in the cover upon removal of cover for the wireless products. Location 1. Should not be installed on an outside wall. 2. Must be installed away from any direct heat source. 3. Should not be installed near an air discharge grill. 4.
13. Re-install the cover (top side first) and gently push extra wire length back into the hole in the wall. 14. Install security screw. If replacing an existing Terminal Equipment Controller, label the wires before removal of the Terminal Equipment Controller. Electronic controls are static sensitive devices. Discharge yourself properly before manipulating and installing the Terminal Equipment Controller.
Binary input #2 can be configured for the following functions: 1. (None): No function will be associated with the input 2. (Door Dry) Door contact & Motion detector: This configuration is only functional if binary input #1 is set to Motion NO or Motion NC or a PIR accessory cover is used. With this sequence enabled, the occupancy is now dictated through those 2 inputs. Any motion detected will set the zone to occupied status.
4. (COS) Change over analog sensor: Used for hot / cold air / water change over switching in 2 pipe systems. Only used and valid if system is setup as 2.0. Parameter ( Out1Conf ) set as 2.0. If temperature is > 77 °F = Hot air / water present If temperature is < 75 °F = Cold air / water present 5. (SS) Supply air sensor monitoring: Used for supply air temperature monitoring. Only used for network reporting of the supply air temperature. Has no internal function in the Terminal Equipment Controller.
Network ready All Viconics VT7200 series Terminal Equipment Controllers are designed for stand-alone (Network Ready) operation. They can be fully integrated into your choice of automation systems using the available communication adapter options.

access to all configuration properties of the Terminal Equipment Controller. Entering a wrong password will prevent local access to the configuration menu. Press the same middle button repetitively to scroll between all the available parameters. Use the up and down key to change the parameter to the desired value. To acknowledge and save the new value, press the middle button again. The next parameter will now be displayed.
PAN ID Personal Area Network Identification Default value = 0 Range is: 0 to 500 Conditional parameter to Wireless models VT7200X5x00W This parameter will only appear when a wireless network adapter is present. If the Terminal Equipment Controller is installed as a stand-alone (Network Ready) unit or with a BACnet™ or Echelon™ adapter, this parameter will not be used or displayed.
Get From Terminal Equipment Controller Get From another device configuration utility Default value = 0 Range is: 0 to 254 Conditional parameter to Wireless models (VT7200X5x00W) Entering a MAC address enables an automatic routine that automatically fetches all the required configuration properties of the current device from another already configured device and copies the same required configured property values.
BI 1 Binary input no.1 configuration Default value = None (None): No function will be associated with the input. Input can be used for remote network monitoring. (Rem NSB): remote NSB timer clock input. The scheduling will now be set as per the binary input. It provides low cost setback operation via a dry contact Contact opened = Occupied Contact closed = Unoccupied (Motion NO) or (Motion NC): Advanced PIR occupancy functions using a Normally Open (NO) or Normally Closed (NC) remote PIR motion sensor.
UI3 Universal input no.3 configuration Default value = None (Filter): a backlit flashing Filter alarm will be displayed on the Terminal Equipment Controller LCD screen when the input is energized. It can be tied to a differential pressure switch that monitor filters Contact opened = No alarm Contact closed = Alarm displayed (Service): a backlit flashing Service alarm will be displayed on the Terminal Equipment Controller LCD screen when the input is energized.
Lockout Keypad lockout levels Default value = 0 No lock USER KEY FUNCTIONS LEVEL 0 1 2 3 4 5 Out1Conf Output # 1 configuration Default is: 4.0 (2 control outputs, no changeover) CntrlTyp Control type for Triac models Default is: Floating SeqOpera Sequence of operation Default is: Sequence #1 0 = Cooling Only NOT USED Defines the type of operation needed for Output #1 (BO1 & BO2) 2.
St-By TM Stand-by Timer value Default 0.5 hours Time delay between the moment where the PIR cover detected the last movement in the area and the time which the Terminal Equipment Controller stand-by mode and setpoints become active. Range is: 0.5 to 24.0 hours in 0.5hr increments Time delay between the moment where the Terminal Equipment Controller toggles to stand-by mode and the time Unoccupied Timer value which the Terminal Equipment Controller unoccupied mode Default 0.
Pband Proportional band setting Default is : 3 Adjust the proportional band used by the Terminal Equipment Controller PI control loop. Note that the default value of 3.0 °F (1.2 °C) gives satisfactory operation in most normal installation cases. The use of a proportional band different than the factory one is normally warranted in applications where the Terminal Equipment Controller location is problematic and leads to unwanted cycling of the unit.
Set Type Temporary setpoint enable Default is : Permnent Enables temporary setpoints feature to any change of occupied or unoccupied setpoint. Temporar: (temporary) Local changes to the heating or cooling setpoints by the user are temporary. They will remain effective for the duration specified by “ToccTime”. Setpoints will then revert back to their default value after internal timer “ToccTime” expires. To change setpoints permanently, revert this variable to No or write setpoints through the network.
