Control Settings
The user can access these control settings by press-
ing and holding the MENU button for 5+ seconds. Any
changes to values are stored into the non-volatile
memory when the MENU button is pressed – which
also toggles to the next setting. Failure to press any
buttons for 60 seconds will cause the screen to revert
back to its previous operating mode screen. However,
the user mode can also be exited by pressing and
holding the MENU button for 5+ seconds.
Set Current Time
This allows setting of the current time. The time is fol-
lowed by an “A” or “P” for AM and PM respectfully. The
control has a 24-hour time clock – although it is NOT
a 7-day time clock. The time clock is used for control
of the pump periods and AUX1 & AUX2 times.
C/F Display
This setting is used to define the units of measure for
all temperature readings. Fahrenheit is the default
value. You can change the setting to Celsius by tog-
gling the UP or DOWN button and then pressing the
MENU button to lock in the change.
Spa Max Temp
This setting is used to define the maximum tempera-
ture that the control can be set at for the Spa
operation. The range is 65F – 104F. The default value
is 104F.
Pool Max Temp
This setting is used to define the maximum tempera-
ture that the control can be set at for the Pool
operation. The range is 65F – 95F. The default value
is 95F.
Pump Periods
When the Pump Operation in the Installer’s Menu is
set to “4-Speed Enabled” or “Variable Enabled”, this
allows the setting of Pump Periods from this menu.
When setting this parameter, the control displays
“Pump Periods” on the first line of the display. The
number of pump periods (0 – 4) is displayed on the
center of the 2
nd
line. Pressing the UP or DOWN but-
tons increments/decrements the number of pump
periods – factory default is 1. If a non-zero number of
pump periods is selected when the MENU button is
pressed, the control will prompt for On/Off times for
each of the selected number of pump periods.
Temperature Control
The control uses the appropriate Pool or Spa setpoint
as selected in the Operating mode. The heat demand
begins when the water temperature is 0.5F or more
colder (or 0.5F or more hotter in cooling mode) than
the setpoint.
Additional Features
Pump Control
The control is equipped to operate the system pump.
The control provides for an output for a single speed
pump (0.75A @ 24VAC maximum) as well as an out-
put for a variable speed pump (10mA @12 VDC).
Four signals are provided for selection of 4 discrete
speeds for a variable speed pump. The control can be
configured to provide a PWM signal on the speed1
output. The control will energize the pump at the
requested speed for each of the pump periods set in
the program mode. If a heat pump demand is present
during a scheduled pump operation, the pump runs at
the override speed (Speed 1) regardless of the sched-
uled speed. When the pump is active because of
scheduled operation and there is no active heat
demand, the control sets the 3-ways valve outputs to
the states set in the program mode schedule.
Low Ambient (Outside) Lockout
The control is equipped with a Low Ambient Lockout
feature which will prevent the start of a new cycle if the
ambient temperature is lower than the programmed
value. This feature is accessed through the
Installer/Service
Sub-menu
as
noted
in
INSTALLER/SERVICE menus on pages 15 - 26. The
default value is “OFF”, but the temperature can be
adjusted between 30F and 50F. This feature can be
enabled if it is desired to not operate the unit if the tem-
perature falls below this value. NOTE: This feature
will NOT stop the operation of an existing cycle, it will
only prevent operation of a new cycle.
An open ambient temperature sensor (display will read
“Air Temp -46F”) will trigger an “Outside Lockout” error
if the Low Ambient lockout is enabled. A shorted (dis-
play will read “Air Temp 282F”) ambient temperature
sensor will also cause the control to shut off the com-
pressor regardless of if the Low Ambient lockout is
enabled.
Control Lock Box Mode
The control is equipped with a Control Lockout feature
which is accessed by pressing and holding the MENU
and DOWN buttons for 5 seconds. The user will be
prompted to enter a 3-digit code. A cursor flashes
under each digit in the 3 digit code when that digit is
