Panel sensors have been pressed too many times in a short
period of time. Because this could cause excessive wear on
equipment components, panel sensors are temporarily
deactivated. Panel sensors will automatically re-activate if no
sensor is pressed for 30 seconds.
Circuit board temperature has exceeded acceptable limit. This
message will disappear when the circuit board temperature
drops below acceptable limit. If condition persists, provide
shade for the equipment side of the hot tub.

required. Pump(s) operate until the hot tub is out of danger.
Note: This error commonly occurs when the hot tub is first filled
because tap water is often very cold.
Communication between the control panel and/or remote con-
trol panel and circuit board is faulty. Contact your dealer or ser-
vice organization.

detected which could cause damage to the hot tub or its com-
ponents. Contact your dealer or service organization.
