AUTOMATIC FUNCTIONS
The most important function of the spa control is to 1.
safely manage the heater. Normally the heater is turned
on whenever the filter pump is running and the water
temperature is 1 degree less than the set temperature.
Once on, the heater will stay on until the water
temperature is 1 degree more than the set temperature.
The heater will be forced to stay off if there is not an
2.
adequate flow of water through the heater. This is
determined by performing a flow test prior to each heater
activation. If the flow of water is too low to cool the
heater 2 degrees in less than a minute, following a 6
second heater test, the heater will not be allowed on and
the statues screen will appear showing a flow rate less
than 6 gal./min.
The
3. heater will also be forced off if too many motors are
running for the size of the circuit breaker.
Anytime the water in the spa is 112F or more, all
4. pumps
are shut down. The pumps can be used again only when
the water temperature has dropped to 104F.
If the water passing through the heater is 118F, or more,
5.
the temperature display is locked on the display and the
heater and all pumps are held off until a manual reset
(circuit breaker) is accomplished. The blower will be turned
on to assist in cooling of the water.
Anytime the heater element (while off) falls to a
6.
temperature of 48F, it is presumed that the spa’s plumbing
may be in danger of freezing. All pumps and the blower
are turned on for 1 minute. If the heater element sensor is
still 48F or less after 1 minute, the blower and pumps are
turned off and the heater is turned on to raise the water
to 60F. If for some reason (flow) the heater can’t be turned
on, the pumps will continue to run until the temperature of
the water reaches 49F.
Once a day, at 10 am, any pump or blower that hasn’t been
7.
running in the last 24 hours is turned on for 15 seconds to
purge stale water.
All components are automatically
8. timed out, as follows:
Pumps – 30 minutes
Blower – 30 minutes
LEDs – 4 hours
Audio – 1.5 Hours
Overview
HOME SCREEN
The main screen will be referred to the “home” screen. The
on screen GUI shows icons. Shown counter clockwise are the
following icons, starting with the No. 1 pump: Pump 1, Pump 2,
Blower (optional Pump 3), Temperature, Setup, Audio, Lighting,
Inverse Screen.
Use the “pump 1”, “pump 2”, or “blower” buttons to UÊ
activate the desired component.
a) If the button is blue, it means the component is off.
b) If the button is green, it means that it is activated.
c) If the button turns red, that means there is some sort
of a problem associated with that component (low
current, blown fuse, disconnected, etc.)
d) If the area is blank, that equipment has not been
installed
Below the icons is a white status bar that appears, and
UÊ
shows the amount of time used and that is left.
Center screen shows temperature in degrees Fahrenheit
UÊ
(or Centigrade), and time. All conditions can be changed.
From any screen that allows for adjustments, a “Back”
UÊ
button will take you to the previous screen.
At the bottom of the screen, a status is given of what is
UÊ
occurring. For example “Circulating” may show.
Timing Status Bar Located Below Icons
Pump 1 timing is nearing end of time cycle. UÊ
Pump 2 is not activated. UÊ
Blower cycle has just turned on. UÊ
Light cycle has approx. 90% time left. UÊ
Audio cycle has approx. 80% time left. UК
