ETT Step Control

ETTAdjustable steps

ETT-6 step controllers are used for step-by-step connection of electric heating coils or refrigeration compressors. They are also ideal for staged connection of fans, cooling packs, pumps, compressors and boilers. ETT-6 is particularly suitable for ventilation systems where the supply air temperature is controlled by sectional electric heating coils or several refrigeration compressors. ETT-6 can be connected to an EFS power controller, providing a cost effective and accurate, infinitely variable regulation of very large electric heating coils in the entire output range.

  • Three-point control
  • Extendable for up to 12 relays
  • Proportional control output
  • Can be connected to an EFM power controller
  • Ideal for staged connection of fans, cooling packs, pumps, compressors and boilers
