ETT-6 Step control by 2 to 12 relays
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.

- Proportional control output
- Can be connected to an EFS power controller
- Ideal for staged connection of fans, cooling packs, pumps, compressors and boilers
