value and press the MENU button to lock in that value.
The cursor moves to the next digit for setting. Once the
last digit is selected (pressing MENU) the display will ask
to confirm the established Lockout code. Press UP or
DOWN button until "YES" is shown and then press the
MENU button to confirm this Lockout code.
NOTE: Record this Lockout code for future reference.
Pressing any button when the control is in Lockout Mode
will prompt the user for the Lockout code. The display
will read "Control Lockout – Enter PIN 000". If the PIN
is entered incorrectly, the display will show "Invalid PIN".
Pressing any button will return the user to the lockout code
screen.
Entering the correct Lockout code will result in the display
showing "Lockout Cleared" and the display will go to the
current operating state of the unit.
Setting for total lockout operation without TIMED SPA
operation (only recommended on systems with pool heat
only):
1. Press the MENU button until SPA is displayed.
2. Press the DOWN button until the setpoint temperature
has been reduced to 65°F (18°C) or lower.
3. Press the MENU button for the next mode selection
and set the desired setpoint temperature for each
mode as appropriate.
4. Program the Control Lock Box mode as noted above.

AUX Mode

The control has the capability to control two auxiliary
outputs for various external uses (rating is 0.75A @ 24VAC
max.). There are 4 selectable modes within the Installer/
Service Sub-menu for auxiliary mode control.
include: AUX OFF (default), AUX OUTPUT, REMOTE
OUT, and EXT HEAT. The control allows setting ON and
OFF times for these 2 auxiliary outputs in the Installer/
Service Sub-menu.
1. AUX OUTPUT – When AUX OUTPUT is selected,
the AUX1 and AUX2 outputs turn ON/OFF from the
time schedule loaded into the control at installation.
Time schedules for each output are independent of
each other. If the OFF time is before the ON time, the
control will assume the Aux output is to be energized
over midnight. If the time of day is not known due to a
clock failure, the AUX output schedules are not run.
2. REMOTE OUT – When REMOTE OUT is selected,
the AUX1 output is used to control another pool
heater (gas, heat pump or solar). This feature is
ideal for when using a HEAT PUMP / GAS HEATER
combo, where a Gas Heater will be providing 'back
up' heating for your Heat Pump. Gas Heaters are
usually used to assist when the temperature is too
cold for a Heat Pump to heat the pool/spa water
effectively on its own, or when the target temperature
will require a larger amount of BTUs than what the
30
Heat Pump Pool Heater can provide on its own,
during a given time and/or outside conditions, in
order to be achieved within the operator's desired
window of time. A Heat Pump, as the more efficient
heating device when used in conjunction with a
Gas Heater, should be the equipment in control of
monitoring the pool/spa water temp and deciding
whether there is a Call for Heat. In the REMOTE
OUT mode, the 'Ext. Heater', i.e. Gas Heater, is not
allowed to heat the water unless the Heat Pump is
on as well.
To take advantage of this feature, set the Heat Pump to
the desired Target Temp, and then set the Gas Heater
to the temperature from which the Heat Pump will no
longer truly need assistance. For example, if your dealer/
installer's calculations, or prior experience, determines
that on your particular pool/spa, the Heat Pump will no
longer need assistance getting the water to a desired
temp of 80°F (27°C) once the water reaches 70°F (21°C),
set the Heat Pump to 80°F (27°C) and the Gas Heater to
70°F (21°C).
The AUX1 output energizes 10 seconds after the first
unit/Heat Pump's compressor and de-energizes when
the first unit/Heat Pump's compressor de-energizes.
AUX2 output is always OFF in this configuration.
REMOTE OUT (Multiple Heat Pumps) – The "Lead Heat
Pump" can control one or more "follower Heat Pump"
with a single setpoint temperature. The AUX1 output
energizes 10 seconds after the "Lead Heat Pump"
compressor and de-energizes after the "Lead Heat
Pump" compressor de-energizes. AUX2 output is always
OFF in this configuration.
3. EXT HEAT – When EXT HEAT is selected, AUX1
output is energized whenever there is a 1st stage
These
heat demand. This allows the use of a solar system
in conjunction with this unit and the control will
operate the solar system first and only bring this
unit on if the heating demand is NOT being met
by the solar system. AUX2 is always off in this
configuration.
The 2nd stage heat pump demand is initiated when water
temperature has remained more than 0.5°F (0.3°C)
colder than the heat setpoint for more than 2 hours, or
when the water temperature is 1.5°F (0.8°C) or more
colder than the heating setpoint.

Remote Pool Operation

REMOTE Mode is accessed by pressing and holding the
UP and DOWN buttons simultaneously for 3 seconds.
When exiting the REMOTE mode, the control always
selects the OFF Mode. If the UP, DOWN or MENU
buttons are pressed while in REMOTE mode, the display
will read "Exit Remote Mode to Adjust Temp". Mode and
temperature setpoints are not changed. Press and hold
