Access setup menu
Table 1A Use this procedure to access the Setup Menu from the display panel
The pool heater will continue to operate while the Setup Menu
is being accessed. To adjust settings, press the MENU button
until the desired screen is displayed. Use the UP and DOWN
buttons to adjust the setting within the screen. By pressing the
MENU or POOL/SPA button the new setting will be stored into
memory and the next screen will be displayed.
When adjusting “set passcode” the 4 individual digits can be
adjusted. The digit on the far left will be active first. Use the UP
and DOWN buttons to adjust the digit. Once the MENU
button is pushed, that digit is stored into memory and the next
digit to the right is active. Continue on until all digits have been
adjusted.
After 1 minute of inactivity, all settings are stored and the
control will exit the Setup Menu. To manually exit the Setup
Menu at any time, press the POOL/SPA button once.
Setup menu descriptions
Pool/spa remote
This setting allows the user to enable or disable the remote
capability of switching from pool to spa. The default setting is
disable.
There are three (3) options under this menu: T Stat, Switch, and
Disable.
T Stat - Select this option when the heater is used in
conjunction with a two wire remote system which includes its
own thermostat. This option will automatically set the set point
to 104° (max.) and all messages on the display will become
generic (i.e. no references to pool or spa). Where there is no call
for heat the pool heater will remain in Standby Mode.
Switch - Select this option when the heater is used in
conjunction with a three wire remote system, also known as a
three-way switch. The remote will control the pool heater if it is
in Pool, Spa, or Standby Mode and will utilize the thermostat on
the heater. When there is no call for Pool or Spa Mode, the pool
heater will remain in Standby Mode.
When in T Stat or Switch Mode, the user can turn the control
“OFF” by pressing the POOL/SPA button on the display.
Disable - This is the default setting. When this option is selected
the heater will ignore all inputs on R, Ws, and Wp. The heater
will not recognize any of the remotes.
For additional wiring instructions consult the third party remote
manufacturer along with the EnergyRite Installation and
Operation Manual.
Differential
This setting allows the user to choose how far below set point the
water temperature must drop before the control will initiate a
call for heat. The range of adjustment is from 1°F to 15°F. The
default setting is 2°F.
Temperature scale
This setting allows the user the choice of showing the displayed
temperature in degrees Fahrenheit or degrees Celsius. The
default setting is Fahrenheit.
Restore defaults
This setting allows the user to restore the factory default settings
for the Setup Menu and temperature settings.
Set passcode
This setting allows the user to set a personal passcode that would
be required to lock and unlock the keypad. See Keypad Lockout
on page 12 of this manual. The default passcode is 1234.
