Feature Circuits
Feature Circuit: A total of 32 Feature Circuits can be assigned to Circuit and
Light circuits. A Feature Circuit is assigned special logic to the circuit. can control
equipment that is not controlled by AUX circuits. Typically, AUX circuits are used
for high voltage equipment like pumps and lights. Feature Circuits are used for low
voltage equipment like valve actuators and pump speeds or pump speeds.
For example, an automatic pool cleaner pump, would assign the circuit function
Master Cleaner. With this cleaner logic the cleaner pump would not run without
the filter pump being on first, and, the cleaner pump would automatically shut
off whenever the spa is switched on. The cleaner will go on after the five minute
delay. Also, the automatic cleaner pump will turn off when the spa and/or solar is
turned on. Be careful not to duplicate circuit names with these circuits. A Feature
Circuit can be assigned to switch a two-speed Filter Pump from high speed to low
speed.
Note: Individual and group circuit buttons only display on the Home Lights screen.
Valve Actuators and Feature Circuits: Feature Circuits can be assigned to control
up to five (5) valve actuators per load center. To control a total of eight (8) actuators
requires the installation of the optional Valve Modules (see page 106) which
includes six (6) additional actuators outputs (C, D, E, F, G, H) per panel enclosure.
Note: When using solar heat, note that for shared equipment pool and spa
combination, valve A is always used for solar. For dual body dual equipment, valve
A is always the pool and valve B is always the spa.
Freeze Protection: Freeze Protection ON, switches on all circuits during, if the
outdoor air temperature sensor detects the temperature is getting close to
freezing (36°F). The system cycles through all circuits that have been assigned
freeze protection, and runs the circuits to stop the pipes from freezing. This is
especially important if there is a pool and spa combination. If freeze protection
is set to both the spa and pool circuits, the filter pump switches on and the pool
and spa valves alternate to keep the water moving in both the pool and spa. This
process continues until the freeze condition is over.
Note: Freeze protection is activated when the air temperature drops to 36°F. If
the spa is running a schedule or operated manually, this will override freeze
protection. During freeze protection, FREEZE PROTECTION is displayed on the
Home screen.
The main pool filter circulation pump is freeze protected as long as FREEZE
PROTECTION is set to ON. For all other equipment, Freeze Protect must also be
specified on the individual device manager screen. Some devices default to freeze
protect.
Heater Operation During Freeze Protection: The heater will not activate during a
Freeze Protection period unless it is manually turned on.
