Spa Equipped Safety Devices - L.A. Spas 2012 North American Owner's Manual

Your spa is equipped with the following safety features:
1. Overheat Protection – All pumps and heater are shut off when the water temperature reaches
112.5°F (44.7°C). This protection is turned off when the water temperature drops below 112°F
(44.4°C).
2. High Limit Protection – When the water temperature reaches 119°F (48°C), the high limit circuit
has tripped. All pumps and heater are shut off. This protection requires the power to be reset at
the circuit breaker.
3. Ambient Overheat Protection – The light output is disabled when an on-board temperature
sensor reaches 194°F (90°C). This protection automatically turns off when the on-board
temperature sensor drops back down to 192°F (89°C). If the internal temperature continues to rise
and reaches 212°F (100°C), all outputs are turned off. This protection automatically turns off if the
temperature at the on-board sensor cools back down to 210°F (99°C).
4. Heater Dry Run Protection – This protection is a water flow detection algorithm of the heater that
prevents the heater from turning on until there is sufficient water flow.
5. Smart Winter Mode – The Smart Winter Mode is used to prevent water from freezing in the
plumbing. When SWM is enabled, the system periodically starts a purge of all pumps and the
blower (if equipped) to ensure there is always warm water in the plumbing. This function is
achieved by measuring the temperature of an on-board sensor to estimate the temperature in the
equipment area. This protection starts as soon as there is a risk of freezing. The SWM protection
will turn back off only after 24 hours without a risk of freezing. The delay between each SWM
purge cycle depends on the pumps' idle time (see table below).

6. Timeouts – The pumps and light turn off automatically after 30 minutes of continuous operation.
