VTC1D
Variable Temperature Control
The VTC-1D is a microprocessor based temperature control that automatically controls temperatures by varying ventilation fan speeds. The control can be internally adjusted to leave fan idling or to shut off the fan when the temperature falls below the Temperature Set Point. The Shut Off temperature is adjustable (Off Setback).

Features:

• 1 Variable Speed output 10 FLAs
  
  
• Extendable Temperature Sensor
  
  
• Temperature Setting adjustable from 32-99°F or 0-38°F
  
  
• 3 Second Full Power Turn-On minimizes fan motor ice up
  
  
• Adjustable Differential
  
  
• Adjustable Idle (0-99% of line voltage)
  
  
• Adjustable Off Setback
  
  
• Displayed Trouble Shooting Codes
  
  
• Electrical Rating: 115/230 VAC
  
  
• 2 year limited warranty
