EFSSimple installation

Type EFS is a series of power controllers designed to control temperature via electric heating elements, e.g. in ventilation systems, electric radiators, electric underfloor and ceiling heating systems or radiant heaters. EFS is particularly suitable for infinitely variable control of large power outputs, e.g. in ventilation systems where supply air temperature is accurately controlled using electric heating elements.  EFS need simply be connected to an electric heating element and a temperature sensor to create a complete heating system.
EFS power controllers are sturdily designed to provide our customers with an advantageous combination of high quality, precise control and low lifecycle costs.

  • Remote temperature setting
  • Built-in power doubling relay
  • Can be used together with an external controller
  • Infinitely variable control of large power outputs
  • Sturdy design
