Viconics Electronics Inc. VT Manuel D’Utilisation

(Issue Date: June 16, 2008 – 028-0183_R3) 

 

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 ).

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. Please use (5500) extension instead of the (5000) only extension.: Ex. VT7300C5500E. 

- 

Thermostats ordered without a PIR cover can be retrofitted with a separate PIR accessory cover afterwards when required
