EL/GL SERIES (Mach 3) CONTROL WITH MLM990S PANEL
The MLM990S panel can be used with the EL8000,
EL5000, EL2000 and EL1000 systems. System software
version 28 or higher is required for this panel. This user
guide lists all features that are available. The features
shown on your panel menus may vary depending on
the system and equipment used.
The pump responsible for heating and filtration
(pump 1 low on non-circ systems, or the circ pump on
circ systems) will be referred to simply as the pump.
Time-outs refer to a preset length of time that a
function is programmed to operate before shutting off
automatically. Certain conditions (filters or freeze) can
cause a function to operate longer, while faults can
cause a function to operate for a shorter length of time.
The system keeps track of time-outs regardless of other
conditions occurring.

E. Additional Options
Freeze Protection
If the temperature sensors within the heater detect a low
enough temperature, then the pump(s) and the blower
automatically activate to provide freeze protection. The
pump(s) and blower will run either continuously or
periodically depending on conditions.
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. Auxiliary
freeze sensor protection acts similarly except with the
temperature thresholds determined by the switch. See
your dealer for details.
Clean-up Cycle
When a pump or blower is turned on by a button
press, a clean-up cycle begins 30 minutes after the
pump or blower is turned off or times out. The pump
and the ozone generator will run for one to four hours,
depending on the system (on some systems, you can
change this setting; see the “User Preferences” section.)
Circ Pump
If your system is equipped with a circ pump, it may be
configured to work in one of three different ways:
1) The circ pump operates continuously (24 hours) with
the exception of turning off for 30 minutes at a time
when the water temperature reaches 3°F (1.5°C) above
the set temperature (most likely to happen in very
hot climates).
2) The circ pump stays on continuously, regardless of
water temperature.
3) The circ pump will come on when the system is
checking temperature (polling), during filter cycles,
during freeze conditions, or when another pump
is on.
Ozone
On most systems, the ozone generator (if installed) runs
during filter cycles (except when pump 1 is operating at
high speed on a non-circ system) and during clean-up
cycles. On some systems, the ozone generator operates
whenever the pump runs.
If your system is configured with the optional ozone
suppress feature, the ozone generator will turn off
for 1 hour any time a function button (Jets 1, Jets 2,
Blower, etc.) is pressed.
