About this item

  • Easy-to-read, bright, adjustable backlit LCD screen displays the temperature
  • Basic and advanced programming menus allow you to easily set up control application on the LCD using a simple 3-button touchpad interface
  • Adjustable on and off temperature setpoints enable easy to set up cooling or heating control applications eliminating the need to remove the cover and reposition jumpers for reverse or direct control actions
  • High and low temperature setpoint adjustment stops
  • Adjustable anti-short cycle delay keeps the output relay off after the off set point is reached for a user-defined time delay, which helps avoid short cycling, hard starts and nuisance overload
  • High-impact, thermoplastic enclosure increase application options, allowing surface and snap-fit DIN rail-mount or watertight surface-mount
  • 1.8 V-A maximum power consumption
