15. DIGITAL CONTROLS
OPERATION
Your heat pump pool heater incorporates digital safety
controls and indicators to ensure safe and reliable
operation. The pool water temperature is controlled by
the heater's digital control system, which provides multiple
operation modes as described in section 10, "Operation
Modes," on page 12.
Furthermore, the unit is compatible with most "2-wire" and
"3-wire" control/automation systems. For more information
about 2 and 3-wire control, refer to section 16, "Remote
Mode Selector", on page 31.
This section explains the general control sequence of
operation, as well as the protections provided by the
heater to ensure safe and dependable operation.
Sequence of Operation
1. Upon the initial application of power, the heater
control briefly illuminates all segments on the LCD
at power-up.
2. The control displays the current software version
on the LCD for 2-seconds, then resumes the user-
selected mode it was in before power was interrupted.
3. If the unit type has not been set, the control prompts
the user to set the model type before enabling any
device operation.
NOTE: The model is set from the factory. If the model
needs to be updated due to a board replacement, use
the special menu "Model Type", available in the Installer
menu. The Installer menu can be accessed from the
Program menu. Refer to section 13, "Installer Menu", on
page 21 for more information.
4. Optional: During the initial operation, there are
several optional items that can be defined and
programmed depending on the intended configuration
and accessories to be controlled by the heater.
These include control of valves, single-speed and
variable-speed pumps, and auxiliary outputs. Once
these options are selected, further information is
required to establish the pump periods, pump speed
during each period, and auxiliary outputs command
for each period, which must be determined and set
in the SCHEDULE menu for local automation or with
Raymote app for remote control with Wi-Fi. Once
programming is completed, the heater control is
ready for operation.
NOTE: Optional control items are not enabled by
default at the factory. To activate and configure these
features, please refer to the "Installer" and "Schedule"
menus. Both menus are accessible from the Program
menu. Refer to section 13, "Installer Menu", on page
21 and section 14, "Schedule Menu", on page 25,
for more information.
5. The user can select one of several operating modes
depending on the unit type. To cycle between
the modes, simply press the MODE key. Each
press of the MODE key selects the next mode.
• For Heat Only models, the available mode
selections are OFF, POOL, SPA, and TIMED SPA.
• For Heat/Cool models, the available mode
selections
are
OFF,
HEAT, POOL AUTO, SPA, and TIMED SPA.
For more information, refer to section 10, "Operation
Modes", on page 12. For information about the
remote mode, please refer to section 16, "Remote
Mode Selector", on page 31.
6. During operation, the unit will run until the water
temperature reaches 0.5°F (0.3°C) above the
setpoint for heating (or below for cooling), or until the
unit is manually turned off.
7. The unit will enter standby mode and wait for the
next demand to start heating or cooling the water.
System Start-Up
1. Ensure that the Digital Board is displaying the correct
temperature and that the pool pump is running, and
water is circulating properly.
2. Confirm that the Board is programmed with the
desired temperature setpoint for the pool and/or spa.
3. Allow the heater to operate for a few minutes to
stabilize the operating pressures and allow various
component temperatures to normalize.
4. After the unit has been operating in heating mode
for a few minutes, check that the discharge air
temperature is approximately 8°F-10°F (4.4°C-5.5°C)
cooler than the air entering the unit.
5. In Heat/Cool models, after the unit has been operating
in cooling mode for a few minutes, the discharge
air temperature should be 8°F-10°F (4.4°C-5.5°C)
warmer than the air entering the unit.
NOTE: Heating is more efficient during warmer daylight
hours, while cooling is more efficient during cooler
nighttime hours. To speed up the cooling process, turn
off the pool/spa blanket and turn on any fountains,
sprays, or other water features at nighttime.
