The heating system will start after 12 hours, and continuously heat until the

spa water temperature drops 1-2°C (1.8-3.6°F) below the set temperature
the heating system will restart. When the fl ame icon on the display is red,
the heating system is activated. When the fl ame icon turns green, the water
is at the set temperature. The heating system is at rest and the fi ltration
system will continue working nonstop.
Freeze Protection:
the spa heater is programed to automatically heat the water if the water
temperature falls below 4°C (39°F). While the spa should be stored during the winter months,
the system will protect the internal components in the event of occasional freezing temperatures.
The spa must be plugged in and the GFCI/RCD reset. The system will engage the fi lter pump
along with the heater and will operate both until the water reaches 10°C (50°F).
If extended freezing weather is expected, please disassemble the spa and store it during winter
according to the storage instructions.
Once the self-heating program is triggered, it cannot be switched off on the control panel until
the water temperature has reached at least 5°C (41°F), unless it is unplugged.
