This controller can be used as a direct replacement for the Surge 28000 LLC.

Because the Surge probes are not compatible with newer systems it is necessary to replace both the control box and the probe set. Available standard in either 110/220V (Selector Switch) and even 12V on special request (Comes with wiring instructions.)

Remember to replace a Surge controller and probe you will not be able to use your old surge probe so select a probe set from the drop down box. The controller is available without probes if needed however it will not work with Surge probes.
