Ozone will only run with Pump 1 in low speed during filtration cycles. For hot tubs with filtration cycles, you will
want to increase filtration cycles to two, four-hour cycles. Hot tubs with continuous circulation pumps do not
need adjustment to their filtration cycles.
1900D Control Panel
Pump
All Jets are powered by a 2 speed pump. Pressing the ‘Pump’ button once puts the pump into low speed.
Pressing a second time activates high speed. To turn off, press a third time. If left running on high speed,
the pump will automatically turn off after 30 minutes (4 hours on low speed).
Blower (not installed)
The blower is not an option for this spa, but the button is required in some key sequences.
Light
The underwater light and grab bar lights (if installed on your spa) are turned on or off by pressing the light
button. In some cases, the light is turned low, medium, high, off. The light button also controls any optional LED
lighting if installed on your spa. By turning the LED lights on and off, you can cycle through the various colors
programmed into the LED controller (Blue/Green, Purple, Blue, Green/Red, Green, Red, cycling through the
colors, strobe effect).
Set Temperature
The Set Temperature button is used to change the temperature set-point of the spa. When the Set
Temperature button is pressed, the display will show the set temperature. Pressing the button a second
time will cause the set temperature to increase or decrease depending on what direction was last chosen.
Each successive press will change the set temperature in the same direction. If the opposite direction is
desired, release the button and let the display revert to the actual water temperature. Press the button
again to display the set temperature, and successive presses will make the temperature change in the desired
direction. The minimum set point is 80°, while the maximum is 104°.
Indicator Light (Heat)
The Heat Light is turned on whenever the heater is activated.
Control Panel Features
Power-up Sequence
When power to the spa is turned on, the Main Control Panel will display a series of diagnostic numbers and/or let-
ters. When the diagnostic mode is finished, the pump will activate on low speed to detect the water temperature.
Panel Lock
To lock or unlock the control panel, press ‘Set Temperature’ then ‘Light’. When locked, the display will alternate
“PL” with the spa temperature..
Temperature Lock
To lock or unlock the temperature set-point, press ‘Set Temperature’ then ‘Blower’. When locked, the display
will alternate “SL” with the spa temperature.
Heater Operation
The 2 speed pump controls all heating and filtration – neither occurs unless the pump is running. The pump may
automatically turn on low speed for approximately 2 minutes every half hour to detect water temperature. If
heating is required, the pump will remain on in low speed. During this time, the pump cannot be shut off but can
be activated to high speed.

Blower
The blower is a 1 speed blower that activates all blower jets. Pressing once activates the blower. To turn off,
press again. If left on, the blower will automatically turn off after 30 minutes.
Mode/Prog
Repeatedly pressing the mode/prog button will cycle through the available Spa Modes (Standard or Economy -
see descriptions below).
Light
The underwater light and grab bar lights (if installed on your spa) are turned on or off by pressing the light
button. In some cases, the light is turned low, medium, high, off. The light button also controls any optional LED
lighting if installed on your spa. By turning the LED lights on and off, you can cycle through the various colors
programmed into the LED controller (Blue/Green, Purple, Blue, Green/Red, Green, Red, cycling through the
colors, strobe effect).
Warm & Cool
The warm & cool buttons are used to change the temperature set-point of the spa. When either button
is pressed, the new set-point is displayed for a few seconds before reverting back to the current water
temperature. The minimum set point is 80°, while the maximum is 104°.
Indicator Lights: Heat
The Heat Light is turned on whenever the heater is activated.
Power-up Sequence
When power to the spa is turned on, the Main Control Panel will display a series of diagnostic numbers and/or
letters. When the diagnostic mode is finished, Pump 1 will activate on low speed to detect the water temperature.
Control Panel Features
Panel Lock
To lock the control panel, press ‘Cool’ then ‘Light’. When locked, the display will alternate “LOC” with the spa
temperature. To unlock, press ‘Cool’ then ‘Mode’.
Temperature Lock
To lock or unlock the temperature set-point, press ‘Cool’ then ‘Mode’. When locked, the display will alternate
“LOCF” with the spa temperature.
Heater Operation
The 2 speed main water pump controls all heating and filtration – neither occurs unless the pump is running.
The pump may automatically turn on low speed for approximately 2 minutes every half hour to detect water
temperature. If heating is required, the pump will remain on in low speed. During this time, the pump cannot
be shut off but can be activated to high speed.
Filtration Cycles
Designate times when the pump activates on low speed to filter the spa water. The first filter cycle begins
6 minutes after the spa is energized. The second filter cycle begins 12 hours later. Filter Cycle duration is pro-
grammable for 2, 3, 4, or 5 hours. The default filter duration is 2 hours. To change the filter duration, press
‘Cool’ then ‘Pump 1’ and use the ‘Cool’ button to adjust. Press ‘Pump 1’ to exit programming. During the first
filter cycle of the day, the blower will activate for 30 seconds.
Spa Modes
Spa Modes can be changed by pressing ‘Mode’. The display will automatically revert to the temperature
after several seconds.
Standar
d Mode constantly maintains the set temperature. The temperature displayed is current only when
the pump has been running for at least 2 minutes. The spa will run for at least 2 minutes every half hour to
determine if the spa requires heating. “St" will be displayed momentarily when you switch into Standard Mode.
E
conomy Mode heats the spa to the set-point when the spa is in a filtration cycle. However, when it is not in a
filtration cycle it will heat the spa to within 15° of the temperature set-point. The display will alternately flash
“ECON”, the current spa temperature, and “COOL” until the water is within 15° of the set temperature.
Freeze Protection
Freeze Protection is activated if the temperature sensors in the heater detect a drop to 44°. All pumps
(including the blower) activate automatically and remain on until 4 minutes after the sensors detect that
the spa temperature has risen to 45° or higher. During this time “ICE” will be displayed and no button presses
will be recognized until the spa water has reached 45°.
Press all buttons firmly. In multi-button
sequences, if buttons are pressed too quickly
or too slowly they may not register and you
will need to repeat the sequence.
