SMART WINTER MODE/FREEZE PROTECTION:
On
board temperature sensors continuously monitor water and
air temperature. If the temperature inside the control box
falls below 59
°
F, the system will start a special program
(Smart Winter Mode) to circulate the water in the plumbing.
For the next 24 hours, the components will be automatically
operated for a period of 1 minute every 2 hours to
thoroughly circulate the water throughout the spa. The time
between the 1-minute operations will steadily decrease as
the air temperature inside the control box drops. If the water
temperature sensor falls below 49
°
F, the heater will be
activated to maintain a temperature above freezing (Freeze
Protection). The Filtration Icon in the upper display will be
flashing when the system has entered either safety mode.
Only while in freeze mode are other functions of the unit
(except the alarms) are disabled.
Note:
If your area
experiences electrical power outages and the climatic
conditions could result in freezing of the water, we suggest
that you contact your local dealer for assistance in proper
drainage and winterizing of your spa to avoid any damage
that may occur from freezing temperatures.
PRESSURE SWITCH:
To assure proper heater operation, a
water pressure switch has been installed to monitor the
system. If 3 flashing dots appear below the temperature in
the LED window, this indicates the need for system service.
Refer to the advanced troubleshooting guide available from
your spa retailer or contact a service technician to correct
the problem.
HIGH TEMPERATURE PROTECTION:
If the water
temperature exceeds 119
°
F, the heater will be turned off and
the High-Limit temperature protection circuit will display 3
flashing dots below the temperature in the LED window. Once
the water has cooled below 110
°
F power to the system must
be turned off, then back on to allow the system to reset. If this
condition persists, refer to the advanced troubleshooting
guide available from your spa retailer or contact a service
technician to correct the problem
TEMPERATURE SENSOR:
To assure proper temperature
maintenance, a temperature probe has been incorporated
into the system. If you notice the displayed temperature
greatly differs from the actual water temperature, or if 32
°
F
is displayed and the correct water temperature is much
higher, this indicates the need for system service. Refer to
the advanced troubleshooting guide available from your
spa retailer, or contact a service technician to correct the
problem
