7.1 Glossary of Safety Delays
Pool/Spa Switching Filter Pump Delay -
The filter pump turns off while valves rotate between pool and spa to prevent damage
to the pool equipment. The valves take 35 seconds to rotate between pool and spa; the filter pump will activate as soon as the
valves have finished turning.
Heater Cool Down Delay -
When the system is heating (water is circulating to the spa) and the Spa button is pressed, the system
will remain in Spa Mode for five minutes, and will continue to circulate the water. This delay allows water to cool the heater down
by circulating water through it, preventing equipment damage. The five minute delay starts counting down when the heater goes
off. If the heater has been off for five minutes or more, prior to turning off the Spa, there will not be a delay.
Heater Start-up -
The heater will only come on if the water is circulating (for example, the filter pump is on and has been
circulating for 15 seconds) to the corresponding body of water (for example, spa for spa heater) and the actual water temperature
is below the temperature you set with TEMP SET in the Menu. If these conditions are not met, the heater will be enabled (ready to
go), but will not fire.
Heater “Short Cycling” Prevention -
When the heater is activated and the desired temperature is reached, heater will turn off and
remain off for three (3) minutes, even if the temperature falls below the desired temperature. This feature prevents heater short
cycling (in other words, the heater turning off and on in rapid succession).
Cleaner Lockout -
The pool cleaner will only activate if the system is in pool mode and water is circulating. The pool cleaner
requires that water is circulating to the pool in order for it to operate. Return to pool mode to activate the cleaner.
Spillover Lockout -
The spillover will only activate if the system is in pool mode and water is circulating. The spillover requires
that water is circulating to the pool in order for it to operate. Return to pool mode to activate the waterfall. Also, if the pool
cleaner is on, it will turn off during spillover operation.
Spillover -
When DIP Switch 3 is in the ON position, the Aux. 3 relay socket is activated and the return valve actuator turns.
The spillover is disabled while the spa is on. A message is displayed when spillover is turned on while in spa mode (water is
circulating to spa). The spillover requires that water circulation is to pool in order to operate. The spillover will activate when the
system switches back to pool mode.
Enabled -
When activated allows the function to work.
Disabled -
When activated does not allow the function to work.
7.2 Glossary of Special Auxiliary Labels
Spare AUX-
Operates only with Pool/Spa combination units.
Extra AUX-
System features (for example, software labeling and timed aux) can be assigned to the EXTRA AUX button. Only
freeze protection cannot be assigned to the extra auxiliary.
Air Blower -
When an AUX button labeled “Air Blower” is pressed, it will turn on the air blower for 30 minutes, then
automatically turn it off. An air blower may be programmed like any other auxiliary, except that you can program only the ON
time. The air blower will turn on at the programmed ON time, and turn off 30 minutes later. This is to protect the blower motor
from overheating during extended operation.
Fill Line -
When an AUX button labeled “Fill Line” is pressed, it will turn on the fill line for 30 minutes, and then automatically
turn it off. A fill line may be programmed like any other auxiliary, except that you can program only the ON time. The fill line will
turn on at the programmed ON time, and turn off 30 minutes later. This is to avoid overfilling the pool. Choose the appropriate
number of "fill" programs during the week to keep your pool at the appropriate level.
