I NSTALLATION Remove the security screw on the bottom of the Fan Coil Terminal Equipment Controller cover. Open unit by pulling on the bottom side of Fan Coil 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.
12. Re-Install wiring terminals in their correct locations (Fig. 3). 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 old Terminal Equipment Controller, label the wires before removal of the old Terminal Equipment Controller. Electronic controls are static sensitive devices. Discharge yourself properly before manipulation and installing the Terminal Equipment Controller.
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. The zone will remain permanently in occupied mode until the door contact switch opens momentarily.
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.
All Viconics VT7300 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.

Occupied, Stand-By, Unoccupied and Override status are displayed on the scrolling display. Alarms If alarms are detected, they will automatically be displayed at the end of the scrolling status display. When an alarm message is displayed, the backlit screen will illuminate at the same time as the message and shut off during the rest of the status display. A maximum of two alarms can appear at any given time.
An Override can be made on commercial models during an unoccupied period. If the Override option is enabled in the lockout configuration, pressing the middle override button will resume occupied setpoints for a time specified by the parameter “ToccTime”.
Local keypad interface Is used to toggle between the different system modes available as per sequence and menu selected. Repetitively pressing the button will toggle between all the available modes. Available menus are dependent on selected sequence of operation.

UI3 Universal input no.3 configuration Default value = None (None): No function will be associated with the input (COC/NH) Change over dry contact. Normally Heat: Used for hot / cold water or air change over switching in 2 pipe systems. Contact closed = Cold water or air present Contact opened = Hot water or air present Only used and valid if system is setup as 2 pipes. Parameter (Pipe No) set as 2 pipes. (COC/NC) Change over dry contact.

Set Type Temporary setpoint enable Default is : Permnent 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. Enables temporary setpoints feature to any To change setpoints permanently, revert this variable to No change of occupied or or write setpoints through the network.
