I am replacing a control box that had a temperature switch,that turned on filter/pump when the temperature went below 35 degrees. Will this device do the same?

A  Answered on 10/27/2014 by InyoPools Product Specialist Patrick P.

Hi Ron - This particular timer does not have the thermostat which would turn your pump on once the temperature drops below 35 degrees. However we do carry this Intermatic Pool Timer with Thermostat which has this feature.

Will this timer work with a two speed pump?

A  Answered on 1/27/2015 by InyoPools Product Specialist Robert M.

The T21004R would not be the correct control panel for a 2-speed pump. We would recommend the Intermatic PE25300 for 2-speed pumps.

I need to replace the box it rusted out, Can I purchase just the box?

A  Answered on 10/14/2020 by InyoPools Product Specialist Hector F.

Unfortunately, that enclosure box is no longer available so you would have to replace the entire control center.
