M-2/M-3 Control Reference Card
Don't Panic! No Programming is Necessary!
Instruction card for M-2 and M-3 systems equipped with Deluxe Digital control panels
 

Initial Start-up
When your spa is powered up, it begins running in an economy mode. This setting is designed for periods of little or no spa use,
but the spa continues to filter twice a day to maintain water quality.
Press the pad to switch the spa to standard mode which will automatically heat and maintain the water at 100 F or your
desired set temperature.
 


 

Control panel pads

      Temperature Adjustment (80F-104F)
 
Press either pad once, and the LCD will display the set
 temperature, as well as the words "SET HEAT." Each time either
 of these pads is pressed again, the set temperature will increase or decrease. After three seconds, the LCD will automatically display
 the current spa temperature.

  Jets

The operating sequence for the pump is low speed, high speed,
then off. If left running, the low speed will automatically turn off
after 4 hours; the high speed will turn off after 30 minutes. The
low speed runs when the heater is turned on, when a filter cycle is activated, or when a freeze condition is detected. When the low
speed turns on automatically, it cannot be deactivated from the
panel; however, the high speed may be started.

Systems with a circulation pump: The pump has only one
speed. It will turn off if the water temperature is 2F above the set temperature. It turns on again at 1F below the set temperature.
The pump always comes on during a filter cycle.

 

 

   Blower

This pad turns the blower on and off. If left on, the blower will
automatically turn off after 30 minutes.

   Light

Your spa light has three settings. Press the pad once for brightest intensity and a second time for medium intensity. Press the pad a
third time for the dimmest setting and a final time to turn the
spa light off. After 4 hours, the light will automatically turn off.

   Economy & Standard Modes

Press this pad to switch between modes. Standard mode
maintains the set temperature at all times.
Economy mode
heats the water only during filter cycles. See the Optional Filter
Cycle Programming section for more heater options.

   Aux (button for optional equipment)

Please refer to your spa manufacturer's literature.

 

Automatic Features

Preset Filter Cycle

four spa will automatically filter itself twice each day. The low
speed of the pump and the ozone generator (if installed) will run
the duration of each filter cycle.

Filter 1

The first filter cycle is automatically activated at 8:00 PM and
operates the low speed of the pump and the ozone generator
(if installed) until 10:00 PM. Again, if the heat enable feature is
on, the spa will heat to the set temperature in the economy mode.
The blower will run for 30 seconds to clean out the air channel.

 

Filter 2

The second filter cycle is automatically activated at 8:00 AM and operates the low speed of the pump and the ozone generator
(if installed) until 10:00 AM. If the heat enable feature is on, the
spa will heat to the set temperature in the economy mode.

Systems with a circulation pump: If your spa has a circulation
pump and an ozone generator, each will run 24 hours per day to constantly maintain the spa water. Also, once a day, the blower
will run for 30 seconds and the high speed of the pump will run
for 5 minutes.

Freeze Protection

If the high-limit sensor detects 40 F at the heater, then all

The equipment stays on until the sensor detects 45 F at the
heater. Freeze protection is enabled regardless of the status of
the spa. In colder climates, an optional additional freeze sensor
may be added to protect against freeze conditions. See your
dealer for details.
