PIR Ready VT7300 Series 24 Vac Low Voltage Fan Coil Thermostats For Commercial and Lodging HVAC Applications (Issue Date: June 16, 2008 – 028-0183_R3) Product overview The VT7300 PI thermostat family is specifically designed for fan coil control. The product features a backlit LCD display with dedicated function menu buttons for simple operation. Accurate temperature control is achieved due to the product’s PI proportional control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based thermostats. Models are available for On/Off, 3 point floating and analog 0 to 10 Vdc control and can control up to three fan speed. Three additional inputs are also provided for monitoring and / or various advanced functions. All models feature configurable System and Fan button functions to meet all possible applications. They all contain an SPST auxiliary switch that can be used to control lighting or auxiliary reheat. The thermostats are also compatible with the new Viconics PIR cover accessories. Thermostats equipped with a PIR cover provide advanced active occupancy logic, which will automatically switch occupancy levels from Occupied to Stand-By and Unoccupied as required by local activity being present or not. This advanced occupancy functionality provides advantageous energy savings during occupied hours without sacrificing occupant comfort. All thermostats can be ordered with or without a factory installed PIR cover ( see ordering notes below ). The additional following documents are available at: www.viconics.com• PIR application information and examples, are available on document: APP-PIR-Guide-Exx • PIR cover installation information is available on document: PIR Cover Installation-Exx • Information on the LON models (VT73xxX5000E), is available on document ITG-VT7300-PIR-LON-Exx • Information on the BACnet models (VT73xxX5000B), is available on document ITG-VT7300-PIR-BAC-Exx • Information on the Wireless models (VT73xxX5000W), is available on documents: ITG-VWG-40-BAC-Exx and LIT-VWG-40-SETUP-Exx Models available Viconics Part Numbers VT7300A5000(X) VT7300C5000(X) VT7350C5000(X) VT7305A5000(X) VT7305C5000(X) VT7355C5000(X) VT7300F5000(X) VT7350F5000(X) VT7305F5000(X) VT7355F5000(X) Application 2 & 4 Pipes On/Off 2 & 4 Pipes Floating & On/Off 2 & 4 Pipes On/Off 2 & 4 Pipes Floating & On/Off 2 & 4 Pipes Analog 0-10 Vdc RH sensor No No Yes No No Yes No Yes No Yes Market Commercial / Institution Hotels / Lodging Commercial / Institution Hotels / Lodging Ordering Information Notes: - (X) model number represents available communication options: X=none for Stand-alone, X=B for BACnet MS-TP, X=E for Echelon and X=W for Wireless - Thermostats can be ordered with a factory installed PIR cover.

2 Programmable 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 applied PIR function and configuration. Application information and examples, are available on document: APP-PIR-Guide-Exx. This document will provide the installers and system designers with detailed examples on 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 thermostat. 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 thermostat 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 & 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 thermostat will then go in 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 thermostat. 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 parameter (TOccTime) temporary occupancy time. 4. (Filter): a backlit flashing Filter alarm will be displayed on the thermostat 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 5. (Service): a backlit flashing Service alarm will be displayed on the thermostat LCD screen when the input is energized. It can be tied in to 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 water change over switching in 2 pipe systems. • Contact closed = Cold water present • Contact opened = Hot water present Only used and valid if system is setup as 2 pipes. Parameter ( Pipe No ) set as 2 pipes. 3. (COC/NC) Change over dry contact. Normally Cool: Used for hot / cold water or air change over switching in 2 pipe systems. • Contact closed = Hot water present • Contact opened = Cold water present Only used and valid if system is setup as 2 pipes. Parameter ( Pipe No ) set as 2 pipes. 4. (COS) Change over analog sensor: Used for hot / cold water or air change over switching in 2 pipe systems. Only used and valid if system is setup as 2 pipes. Parameter ( Pipe No ) set as 2 pipes. • If temperature is > 77 °F = Hot water present • If temperature is < 75 °F = Cold 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 thermostat. .

9 Programming and status display instructions Status display The thermostat 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 thermostat has an auto scrolling display that shows the actual status of the system. There is an option in the configuration menu to lockout 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 back lighting in low level mode. Pressing any key will cause the back light to come on to high level. When left unattended for 10 seconds after changes are made, the display will resume automatic status display scrolling. To turn on the back light to high level, press any key on the front panel. The back lit display will return to low level when the thermostat is left unattended for 45 seconds Sequence of auto-scroll status display: Room & Humidity System Mode Schedule Status Outdoor Temperature Alarms x.x °C or °F Sys mode Occupied Outdoor Service XX % RH Auto x.x °C or°F If humidity display enabled Sys mode Cool Stand-By Network value only Filter RoomTemp x.x °C or °F Sys mode heat Unoccup Window If humidity display is not enabled Sys mode off Override % RH display is conditional to: (Humidity display is model and configuration dependent) • Model with RH sensor built in • Display function can be enabled with RH display parameter.

Viconics recommends using only the 2 last channels ( 25-2575MHz and 26-2580MHz ) The default value of 10 is NOT a valid channel. The valid range of available channel is from 11 to 26
12 Get From Thermostat Get From another device configuration utility Default value = 0 Range is: 0 to 254 Conditional parameter to Wireless models (VT730xX1000W) This parameter / function is not currently supported by the wireless thermostats. BI1 Binary input no.1 configuration Default value = None (None): No function will be associated with the input (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. Occupancy mode is now set as per applied PIR function and configuration. Application information and examples are available on document: APP-PIR-Guide-Exx. This document will provide the installers and system designers with detailed examples on applications, parameter configuration information, sequence of operation, troubleshooting and diagnostic help required for the proper usage of the PIR accessory covers (Window) EMS: Forces the system to disable any current heating or cooling action by the thermostat. 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 thermostat to indicate to the local tenant that the door/window needs to be closed for cooling or heating to resume. * these settings will disable the local override function on the thermostat. BI2 Binary input no.2 configuration Default value = None (None): No function will be associated with the input (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. The thermostat will then go in 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 (RemOVR): temporary occupancy remote override contact. This function disables the central button override function on the thermostat. 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 parameter (TOccTime) temporary occupancy time. (Filter): a backlit flashing Filter alarm will be displayed on the thermostat 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 thermostat LCD screen when the input is energized. It can be tied in to the AC unit control card, which provides an alarm in case of malfunction. Contact opened = No alarm Contact closed = Alarm displayed
