5.5 Lock Out Mode
The control panel temperature display flashes when the Lock Out Mode is active. Lock Out
Mode disables all hot tub functions to permit filter cleaning. If the hot tub is heating when
lockout mode is selected, the heater will immediately turn off and the circulation pump will
cycle water for 30 seconds to cool the heater element, then turn off. See section 4.2 (page
20).
5.6 Summer Logic
When the water temperature in the hot tub rises 2ºF (1ºC) above the set temperature setpoint.
The hot tub goes into “Summer Logic.” When this happens, the circulation pump automati-
cally turns off to prevent additional heat build up from the pump that would eventually cre-
ate an overheat condition. The circulation pump, main pump and aftermarket ozone (when
installed) will remain off until the water temperature cools to the set temperature, then reac-
tivate as programmed. This setting is not user-programmable.
Note: Summer Logic does not take effect until the hot tub’s water reaches 95ºF (35ºC) or higher.
