DC Controller diffrences fk-35 & wp-35

[BEEBE]

Hey guys, Im looking to purchase a controller for a Mark VIII Fan.



When looking at the Delta Current website , the only diffrences I see between the wp-35 and the fk-35 is the type of temp sensor, and a few little connectors.

At the moment I plan to control a fan but in the future I plan to control a Water Pump .

I guess The big question is - Will the WP-35 temp sensor work ok to control just Fan for the moment?

Being that the wp-35 sensor mounts the the thermostat housing & The fk-35 sensor is a probe you stick into the radiator.


Thanks for the input
