VT7200X Series Product Overview
The VT7200 PI thermostat family is specifically designed for zoning applications. Typical applications include local hydronic reheat valve control and pressure dependent VAV with or without local reheat. The product features a backlit LCD display with dedicated function menu keys 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 3 point floating and analog 0 to 10 Vdc control. In addition remote room sensing is available.
They all contain an SPST auxiliary switch that can be used to control lighting or auxiliary reheat. 3 additional inputs are also provided for monitoring and / or various advanced functions.

VT73xxX Series 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 speeds. Three additional inputs are also provided for monitoring and / or various advanced functions.
All models feature configurable System and Fan button functions to meet
VT73x5X Lodging VT73x0X Commercial
all possible applications. They all contain an SPST auxiliary switch that can be used to control lighting or auxiliary reheat.
All devices are also available with Echelon, BACnet MS-TP or Zigbee wireless network adapter. 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.

Input Network Variables (nvi’s) Description
Parameter Variable Name Function
Room Temperature
network input SNVT_temp_p
nviSpaceTemp
This input network variable provides a network remote temperature
value to the thermostat. When linked of written to, the internal temperature reading (internal sensor) is no longer used.
Valid Range: 40 to 122°F (-40 to 50°C) Default Null (release) Value: 621.81°F (327.67°C or 0x7FFF) This network variable is subject to the Receive HeartBeat Time,
nviRcvHrtBt. Outdoor Air Temperature
network input SNVT_temp_p
nviOutdoorTemp
This input network variable provides outdoor air temperature
information to the thermostat from a network value temperature
value. The device will automatically display the value on its display
when linked.
Valid Range: 40 to 122°F (-40 to 50°C) Default Null (release) Value: 621.81°F (327.67°C or 0x7FFF)
Occupied Cool & Heat Setpoints
network Input SNVT_temp_p
nviSetpoint
This input network variable is used to allow the occupied
temperature setpoints only to be changed via the network from a
single analog value. (Note: the Stand-By and Unoccupied setpoints
are not changed). The corresponding heating and cooling values
are derived from the minimum deadband configuration value
Default Null Value: 621.81°F (327.67°C or 0x7FFF) Ex. If the minimum deadband configuration value = 2 °F and
nviSetpoint = 70°F.
• The resulting Occupied heating setpoint will equal 69 °F which is derived from 70 °F minus ½ the minimum deadband configuration value of 2 °F
• The resulting Occupied cooling setpoint will equal 71 °F which is derived from 70 °F plus ½ the minimum deadband configuration value of 2 °F
Room Humidity
network input SNVT_lev_percent
nviSpaceRH
This input network variable is the measured room humidity in
percent monitored by the thermostat.
Valid Range: 5 to 90% Default Null Value: +163.835 (0x7FFF) This network variable is subject to the Receive HeartBeat Time,
nviRcvHrtBt

Parameter Variable Name Function
Fan Mode network input
SNVT_switch
nviFanSpeedCmd
This input network variable is used to connect an external fan
speed switch to the node or to allow any supervisory device to override the fan speed controlled by the node’s control algorithm.
This input is used in conjunction with FanMenu bit in nciGenOpts. Default Null Value: AUTO (state = 0xFF) Valid Range:
