Danfoss Refrigeration Controller, ETC 1H
The ETC 1H is introducing a flexible platform due to onboard micro-controller and software dedicated product configuration, perfect for light commercial applications and household applications. 

Standard versions with similar functionality as the traditional electromechanical thermostats are available as well as several customized high performance software versions.
Features
  • ETC1H can control the cabinet temperature directly
  • ETC1H has low energy consumption
  • 1 or 2 sensors (Air, evaporator) and optional remote display can be connected
  • Using NTC temperature sensors
  • Temperature control independent of barometric pressure
  • High accuracy combined with close differentials and narrow tolerances ensures improved control
  • Built in timers enhances functionality
  • Optional alarm for over or under temperature in both cold and warm
  • Auxiliary relays: 5 Amp for heater, fan, light etc. Eventually with delayed start or/and stop
  • Under voltage and over voltage compressor protection (brown-out protection)
  • Pressure equalisation protection on starting the device or when voltage drops out (blackout protection)
  • Diagnostics and self check of sensors and potentiometer
  • Several defrosting methods can be handled: Time controlled defrosting, and time controlled defrosting with evaporator sensor: Temperature controlled defrosting
  • Dual band control of outdoor bottle coolers
