Cleaning the Room Controller

NOTICE

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. Should not be affected by direct sun radiation.
  5. Nothing should restrict vertical air circulation to the Fan Coil Terminal Equipment Controller.

Installation

  1.  Swing open the Fan Coil Terminal
  2. Equipment Controller PCB to the left by pressing the PCB locking tabs (Fig. 2). Pull out cables 6” out from the wall.Viconics-VT7300-Room-Temperature-Control-Thermostat-fig.2
  3. Wall surface must be flat and clean.
  4. Insert cable in the central hole of the base.
  5. Align the base and mark the location of the two mounting holes on the wall. Install the proper side of the base.
  6. Install anchors in the wall.
  7. Insert screws in mounting holes on each side of the base (Fig. 2).
  8. Gently swing back the circuit board on the base and push on it until the tabs lock it.
  9. Strip each wire 1/4 inch from the end.
  10. Insert each wire according to the wiring diagram.
  11. Gently push excess wiring back into the hole (Fig. 3).
  12. Re-install wiring terminals in their correct locations (Fig. 3).Viconics-VT7300-Room-Temperature-Control-Thermostat-fig.3
  13. Re-install the cover (top side first) and gently push the extra wire length back into the hole in the wall.
  14. Install security screw.

Anti-short cycling can be set to 0 minutes for equipment that possesses its own anti-cycling timer. Do not use that value unless the equipment is equipped with such an internal timer. Failure to do so can damage the equipment.

CONFIGURABLE BI/UI INPUTS OVERVIEW

Binary input #1 can be configured for the following functions:

  1. (None): No function will be associated with the input
  2. (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
  3. (Motion NO) and (Motion NC): Advanced PIR occupancy functions using a normally open (NO) or normally closed (NC) remote PIR motion sensor. Occupancy mode is now set as per the applied PIR function and configuration. Application information and examples are available on the document: APP-PIRGuide-Exx. This document will provide the installers and system designers with detailed examples of applications, parameter configuration information, sequence of operation, troubleshooting, and diagnostic help required for the proper usage of the PIR accessory covers
  4. (Window) EMS: Forces the system to disable any current heating or cooling action by the Terminal Equipment Controller. The mode stays the same and the current setpoints are the same occupied setpoints. Only the outputs are disabled. There is a Door/Window alarm displayed on the Terminal Equipment Controller to indicate to the local tenant that the door/window needs to be closed for cooling or heating to resume. Use NC contact.
    • Contact opened = System disabled with local Window Alarm
    • Contact closed = System enabled

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 and 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. The Terminal Equipment Controller will then go into stand-by mode. If more movements are detected, the occupied mode will resume. While the door is opened, any movements detected by the remote  PIR sensor or the PIR accessory cover will be ignored. Use a Normally Closed-contact switching device.
    • Contact opened = Door opened
    • Contact closed = Door closed
  3. (RemOVR): temporary occupancy remote override contact. This function disables the central button override function on the Terminal Equipment Controller. The override function is now controlled by a manual remote momentarily closed contact. When configured in this mode, the input operates in a toggle mode. It is now possible to toggle between unoccupied & occupied setpoints for the amount of time set by the parameter (TOccTime) temporary occupancy time.
  4. (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 monitors filters
    • Contact opened = No alarm
    • Contact closed = Alarm displayed
  5. (Service): a backlit flashing Service alarm will be displayed on the Terminal Equipment Controller LCD screen when the input is energized. It can be tied into the AC unit control card, which provides an alarm in case of malfunction.
    • Contact opened = No alarm
    • Contact closed = Alarm displayed

Universal input #3 can be configured for the following functions:

  1. (None): No function will be associated with the input
  2. (COC/NH) Change over dry contact. Normally Heat: Used for hot/cold air/water change over switching in 2 pipe systems.
    Contact closed = Cold air/water present
    Contact opened = Hot air/water present
    Only used and valid if the system is set up as 2.0. Parameter ( Out1Conf ) set as 2.0.
  3. (COC/NC) Change over dry contact. Normally Cool: Used for hot/cold air/water change over switching in 2 pipe systems.
    Contact closed = Hot air/water present
    Contact opened = Cold air/water present
    Only used and valid if the system is set up as 2.0. Parameter ( Out1Conf ) set as 2.0.
  4. (COS) Change over analog sensor: Used for hot/cold air/water change over switching in 2 pipe systems.
    Only used and valid if the system is set up 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.

Status display

The VT7200 series wall-mount Terminal Equipment Controller features a two-line, eight-character display. There is a low-level backlight level that is always active and can only be seen at night.
When left unattended, the Terminal Equipment Controller has an auto-scrolling display that shows the actual status of the system. There is an option in the configuration menu to lock out the scrolling display and to only present the room temperature and conditional outdoor temperature to the user. With this option enabled, no local status is given of mode, occupancy, and relative humidity.
Each item is scrolled one by one with the backlighting in low-level mode. Pressing any key will cause the backlight to come on to a high level. When left unattended for 10 seconds after changes are made, the display will resume automatic status display scrolling.
To turn on the backlight to a high level, press any key on the front panel. The backlit display will return to a low level when the Terminal Equipment Controller is left unattended for 45 seconds.
