The evaporator refrigerant pressure has
risen above 190 psig (future use – add "for
continuous15 seconds"). The evaporator
water pump relay will be de-energized to
stop the pump regardless of why the pump

is running. The diagnostic will auto reset
and the pump will return to normal control
when the evaporator pressures falls below
185 psig. This diagnostic must shutdown the
chiller if it is running.
