Using the Control Panel
Starting and Stopping the Heat Pump
The XLHP™ Heat Pump is started and stopped with
the ON/OFF button.
1. Starting - With power supplied to the heat pump,
press the ON/OFF button to start the heat pump.
The ON light should be lit.
2. Stopping - Press the ON/OFF button to stop the
heat pump; the ON light will turn off. The screen
shown below will be displayed temporarily.
Changing the Set Point (Temperature)
The control board has two independently adjustable
temperature set points. One is for the TANK1
temperature control and the other is for the TANK2
temperature control. The active mode of operation
(TANK1 or TANK2) is defined as the “active” set point.
1. Press the MENU SELECT button repeatedly until
the associated run screen is displayed. Press
the UP or DOWN arrows to adjust the TANK1 or
TANK2 temperature set point.
SET= __ - Set point
ACT= __ - Actual measured water temperature
2. The screen automatically returns to the active
run screen after 15 seconds of keypad inactivity.
Heat, Cool, and Auto Modes
Certain models have the ability to both heat and
cool. These heat pumps can be setup to operate
in any one of three modes:
•
Heat only mode
•
Cool only mode
•
Automatic Heat and Cool:
The heat pump automatically switches between
heat and cool based on whether the water
temperature is below or above the active set
point.
1. If the cooling option is available, press the MENU
SELECT button repeatedly until the Heat, Cool
or Auto screen displays.
2. Press the UP or DOWN arrows to scroll through
the heat, cool and auto options. The last option
shown on the display becomes active.

Heat Pump Timer
This feature is an adjustable timer to allow the heat pump to run
for a predetermined amount of time (green light ON) and then turn
OFF (green light OFF).
During the selected time frame, the green light is ON and the heat
pump functions in the normal mode of operation. When time expires
the green light turns off, and the heat pump turns off. Countdown
time is in hours and minutes.
To activate the heat pump timer:
1. Press MENU SELECT repeatedly until the heat pump timer
screen is displayed.
2. Press UP or DOWN arrows to set the amount of time (range
of 10 minutes to 99 hours). Timer adjusts in increments of 10
minutes.
If the heat pump is not already on, setting the timer will activate
and start the heat pump.
3. The user can also change the time while it is active using the
arrow buttons, only if Relay Remote mode is OFF. Turning
Relay ON disables the Heat Pump Timer at the control panel.
4. The timer can be disabled by pressing the DOWN arrow and
TANK1/TANK2 buttons at the same time, or by pressing the
ON/OFF button.
Relay Remote
Note: The XLHP heat pump has been tested and rated as an
aquaculture duty product, however, it is based upon a heat pump
product platform that is also used in the swimming pool industry. The
XLHP heat pump’s control board was originally developed for use in
swimming pool applications and the Relay Remote spade terminals
are labeled “POOL” and “SPA”. In the aquaculture application these
labels correspond to “TANK1” and TANK2” respectively.
In Relay Remote operation, the heat pump is started and stopped by
remote relays which are connected to the remote TANK1, COMMON
and TANK2 spade connectors on the back of the control board.
When conductivity is provided between the TANK1 and COMMON
connections or the TANK2 and COMMON connections, the heat
pump will start. The local Set Points are ignored in Relay Remote
operation. All other features and functions (except for the Heat
Pump Timer) are still active; the heat pump will not heat above
104˚F or cool below 45˚F.
To activate the Relay Remote Mode:
1. Press MENU SELECT repeatedly until the Remote Mode
screen is displayed. Once displayed, press the UP or DOWN
arrows to toggle between OFF and RELAY. The last option
shown on the display becomes active.
2. Press MENU SELECT repeatedly until the Heat/Cool/Auto
Mode screen is displayed. Press UP or DOWN arrow to toggle
between HEAT, COOL and AUTO. Select HEAT or COOL.
AUTO is not a valid selection while the heat pump is in Remote
mode operation.
