Manufacturer web site shown no longer appears available.

Internet archive shown below kept some of the web site, and you might try the default 3 digit pin to see if that works. Otherwise, a locksmith to force it to open might be paid.

It sounds like thermostatic operation is not working.
I cannot offer specific repair, but can offer resources

3) Open following link for recirculation system resources including some manuals, but I don't have your exact manual.
http://waterheatertimer.org/Water-heater-recirculation-system.html
I can see your product on following link
http://www.houseneeds.com/shop/plumbing/recirculators/waterrecirculatorindex.asp

4) Recirculation systems operate 2 ways: with thermostat or timer.
Thermostat is supposed to turn off circulation when water reaches 100 degrees approx.
Until thermostat is repaired, you can work around problem by moving slide switch to TIMER and set timer to run intermittently so temperature at faucet is moderated.

5) Adjust temperature at water heater
