OPERATION (continued)
Heat Button:
Press this button to activate the heating system. Press or to set the desired water
temperature. The heater will continuously heat until the water temperature reaches the set temperature
and then hold at that temperature. This is achieved by the heater restarting automatically whenever
the water temperature drops 1.8-3.6°F (1-2°C) below the set temperature. 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 then at rest, but the fi ltration system will continue circulating water
nonstop, unless manually turned off . If the heating system is reactivated, the fi lter pump will restart at the
same time.
NOTE:
To stop the fi ltration system while the heater is at rest mode, press the fl ame button fi rst and then
the fi lter button. Pressing the heat button only while the heater is at rest mode will turn off the heating
system only and the fi ltration system will operate for 1 more minute before it turns off or continue with the
fi lter pump preset operating hours. To turn the heater off while heating, press the fl ame button.
IMPORTANT:
The following conditions will lead to slow water heating.
• The ambient temperature is lower than 50ºF (10ºC).
• Outdoor wind speed is above 3.5-5.4 m/s (8-12 mph).
• The air bubble function is activated when heating the spa water.
• The spa is not properly covered with the spa cover when the water is heating.
Heater Start Timer (HST) Button:
Use this button to select a future start time for the heating system.
Press this button and then press or to set the number of hours by which you wish to delay the
start of the heating system, from 000 to 120 hours. The icon will fl ash red for a few seconds and then
stays red. The information shown on the LED display alternates between the remaining hours before
heater start and the water temperature. Once the countdown timer reaches 000, the heating system will
start operating. To deactivate the function at any time, simply set the HST time back to 000. To readjust
the preset hours, press the HST button twice and adjust the hours with and buttons.
Example 1:
It is 9:00pm Monday evening and you would like the spa to be hot on Friday evening.
Allowing for 24 hours for the spa to heat up (4 persons model about 3-4.5ºF (1.5-2.5ºC) per hour) the
heater should be set to start on Thursday evening. With the Spa turned on, fi rst press the Heat button
and set your desired temperature. Press the HST button and then or until 072 hours is shown.
The heater will start after 72 hours has passed (Thursday at 9:00pm) and will run until the desired
temperature is attained. The heater will then cycle on and off to maintain the set temperature until turned
off . To turn off the heater, press the fl ame button.
Heater Duration Timer (HDT) Button:
Use this button to select the desired length of time the heating
system should operate. Press this button and then press or to set the number of hours you wish
the heater to operate before it automatically turns off , from 000 to 048 hours. The icon will fl ash red for
a few seconds and then stays red. The heating system will operate for the amount of preset hours only.
The timer takes priority over temperature, so the heater will shut off when HDT time runs out regardless
if the preset spa water temperature is reached or not. During the HDT function, the information shown
on the LED display alternates between the remaining heater operating hours and the water temperature.
Repeat previous steps to reprogram this function. To deactivate the function at any time, simply set the
HDT time back to 000. To readjust the preset hours, press the HDT button twice and adjust the hours
with and buttons.
Example 2:
Using the same scenario as example 1 above but rather than manually turning the heater off
when you are fi nished, you would like the heater to turn off automatically on Saturday evening at 9:00pm.
After going through the steps in example 1, press the HDT button and then the or button to select
048 hours. The heater will then run from Thursday at 9:00pm to Saturday at 9:00pm.
NOTE:
If HST and HDT timers are both set, the LED display will fi rst alternate between remaining time
before the heater start and the water temperature, until HST timer runs out and the heater activates.
Then the LED display alternates between remaining HDT time and water temperature until the HDT timer
runs out as well.
