Controllers: SLEXT Range Extender

SLEXT Range Extender Unit

The SLEXT is a range extender unit that extends the RF signal range of an SL or CRXSL controller to reach heaters that are not close enough to receive wireless transmission. Poor wireless transmission are caused by barriers such as walls or metal objects; or where a controller is mounted close to power cables, motors or equipment producing a strong electromagnetic field. With the SLEXT, the RF signal is repeated, thus extending the reach to heaters in an area or building. The SLEXT is surface mountable and easy to install.

  • Can double the range of all SL or CRXSL controllers
  • Can be retrofitted
  • Can control multiple heaters*
  • Simple pairing to controller and heaters

* Requires a separately purchased SL or CRXSL controller.
