Dynasty Spas 2000LEM-7 User Manual

Temp Set (80°F - 104°F / 26°C - 40°C)

The start-up temperature is set at 100°F/37.5°C. The last
measured temperature is constantly displayed on the LCD.

Note that the last measured spa temperature displayed
is current only when the pump has been running for at
least 2 minutes.

Press the “Warm” or “Cool” button to display and adjust the set
temperature. After three seconds, the LCD will automatically
display the last measured spa temperature.

Jets

Touch the “Jets” button once to activate the low speed of the
pump and again for the high speed. Press the “Jets” button
again to turn off pump 1. If left running, the pump’s low
speed will automatically turn off after 4 hours, and the pump’s
high speed will automatically turn off after 15 minutes.
The pump’s low speed runs when the spa is heating, when a
filter cycle is activated, or when a freezing condition is
detected. When the low speed turns on automatically, it cannot
be deactivated from the panel; however, the high speed may
be started.

Note: The pump can also be activated by an optional
auxiliary control button.

Light

Press the “Light” button to turn the spa light on and off. If
left on, the light automatically turns off after 4 hours.

If a fiber optic light is installed, press the “Light” button once
to start the light and wheel, press it again to stop the wheel,
and then again to turn the light off.

Blower

This button turns the blower on and off. The blower
automatically turns off after 15 minutes.

Mode

This button is used to switch between Standard, Economy, and
Sleep Modes.

2000LE M-7 Control Reference Card

Non-Circ Operation

Initial Start-up

When your spa is first activated, it will go into Priming mode, indicated by “.”Please see the M-7 Installation Instruction

Manual for complete instructions on Power-up and Pump Priming.

The Priming mode will last for less than 5 minutes and

then the spa will begin normal operation in Standard Mode.

Standard Mode is programmed to maintain the desired
temperature. Note that the last measured spa temperature
displayed is current only when the pump has been running
for at least 2 minutes. “ ” will be displayed momentarily
when you switch into Standard Mode.

Economy Mode heats the spa to the set temperature only
during filter cycles. “ ” will display solid when temperature
is not current, and will alternate with temperature when
temperature is current.

Sleep Mode heats the spa to within 20°F of the set
temperature only during filter cycles. “ ” will display solid
when temperature is not current, and will alternate with
temperature when temperature is current.

Preset Filter Cycles

The first filter cycle begins 6 minutes after the spa is energized.
The second filter cycle begins 12 hours later. Filter duration is
programmable for 2, 4, 6, 8 hours or for continuous filtration
(indicated by “FILC”). The default filter time is 2 hours. To
program, press “Warm” or “Cool,” then “Jets.” Press “Warm”
or “Cool” to adjust. Press “Jets” to exit programming.

The blower purges for 30 seconds at the beginning of each
filter cycle. The low speed of the pump runs during filtration
and the ozone sterilizer (if installed) will be enabled.

Freeze Protection

If the temperature sensors detect a drop to approximately
44°F/6.7°C within the heater, then the pump and the blower
will automatically activate to provide freeze protection. The
equipment stays on until 4 minutes after the sensors detect
that the spa temperature has risen to approximately 45°F/7.2°C
or higher. In colder climates, an optional additional freeze
sensor may be added to protect against freeze conditions that
may not be sensed by the standard sensors. Aux freeze sensor
protection acts similarly except with the temperature
thresholds determined by the switch and without a 4-minute
delay in turnoff. See your dealer for details.

°C at the heater.

“Overheat” - The spa has shut down. One of
the sensors has detected that the spa water is

Spa is shut down. The sensor that is plugged
into the Sensor “B” jack is not working.

Sensors are out of balance. If alternating
with temperature, it may just be a temporary
condition. If flashing by itself, spa is
shut down.

A substantial difference in temperature has
been detected between temperature sensors.
This could indicate a flow problem.

Persistent low flow problems. (Displays on the
fifth occurrence of the “HFL” message within
