M-1 Control Reference Card
Quick reference for all M-l control systems.
When your spa
is first actuated, it will be in the default setting and will heat the water to
100 °F or your desired set temperature.
Depending upon the size of the spa and heater capacity, it should be ready for
use in a matter of hours.
Your spa will have one of the
following control panels installed.
These instructions include all possible features found on an M-l
system. Please refer to your spa manufacturer's literature
for features found on your
Temperature Adjustment (Range: 80°F-104°F)
adjustment is controlled by pushing the
pad. The display shows the actual
water temperature unless the pad is
pressed. When the pad is pressed, the
display will show the set temperature. Pressing the pad a second time will cause
to increase or decrease depending on what direction was last chosen. Each press
to follow will change the set temperature
in the same
opposite direction is desired, release the pad and let the display revert to the
actual water temperature. Press the pad to
set temperature, and again to make the temperature change in the desired
pad to turn on the low speed of the pump. Press the pad again to turn on the
high speed of the pump. (If the spa has a
press the pad again to turn on the high speed of both pumps. Then, press the pad
again for pump 2 only.) Press the pad a
final time to turn off the pump(s). Due
to Automatic Spa Control, the low speed of the pump will start automatically
when the heater
is turned on, when a filter cycle is activated, or when a freeze
condition is detected. If the low speed of the pump is on under
Spa Control, it cannot be deactivated from the panel; however, the high speed of
the pump(s) may be started. If left on, the
low speed of
the pump will automatically turn off after 4 hours; the high speed will turn off
after 30 minutes.
pad to turn the blower on and off. The blower will automatically turn itself off
after 30 minutes. (Note: If the system is
in 20A mode,
the blower will revert to a lower speed if the high speed of the pump is on.)
pad to turn the spa light on and off. The light will automatically turn
off after 4 hours.
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 speeds of pump 1 and
pump 2 will run for 5 minutes.
Preset Filter Cycles (models
not equipped with circulation pumps)
Your spa will automatically filter itself twice each day. The first filter cycle
will begin 1 minute after the spa is energized. The second
filter cycle will begin 12 hours after the start of the first filter cycle.
Filter duration is programmable at the topside panel for 2, 4, 6, or
The default filter time is 2 hours. To program, press the "Set" pad, then the
"Jets" pad. Press the "Set" pad to select the filter
duration. Press the "Jets"
pad again to exit the programming mode. During filtration, the low speed of the
pump will run. To clean out
the air channel, the blower will run for 30 seconds and the high speed of pump 2
will run for 5 minutes at the start of the first filter
cycle. The ozone generator will be disabled for 1 hour when any function button
is pressed, then turns on for 4 hours with the low
speed of the pump to clean
If the high-limit sensor detects 40°F at the heater, then the pump(s)
automatically activates to provide freeze protection. This is a
function; no corrective action is necessary. The equipment stays on until the
sensor detects 45 °F at the heater. Freeze
protection is enabled regardless of the spa's status.
Note: In colder climates, an optional additional freeze sensor is used to
protect against freeze conditions. See your dealer for details.
Protection (Spa is deactivated)
DO NOT ENTER THE WATER. If the spa water has reached 112 °F, remove the spa
cover to cool the water. Overheating may
occur if the filter cycle is set too
long. At 110°F, the spa should reset itself. If the high-limit sensor detects
118°F at the heater,
the spa will shut down. When the heater cools to 110°F, press any button to
reset the spa. If the spa will not reset, then shut
off power to the spa and call your dealer or service organization.
