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 in which 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, thus providing a cost effective and accurate infinitely variable regulation of very large electric heating coils in the entire output range. |
