GSE Controller Temperature & Min-Max Hysteresis Speed

GSE logo

This digital temperature, minimum/maximum- speed controller with hysteresis setting is a temperature-dependent speed controller for ventilated rooms with one or more exhaust fans (up to 600 watt).

The controller keeps the temperature constantly and impedes to run under the set minimum-speed, as well to run over the set maximum speed. The hysteresis defines the temperature range. It can be easily controlled, adjusting the required temperature minimum-, maximum speed and hysteresis on four knobs.

Ready to use, this reliable fan controller comes complete with:

  • Sealed water resistant cover
  • Plugs with flap-lids and a low voltage sensor making it perfect for humid rooms.
  • Protection class IP44
  • Digital sensor supplied with 4 metre cable
  • 2.5 amp maximum


All G.S.E products are engineered and manufactured in Europe and are available exclusively from Growth Technology retailers.
