GENERAL DESCRIPTION of HP7 CONTROLLER
The HP7 is a powerful microprocessor control designed for use in swimming pool & spa heat
pumps. The control features 3-digit temperature and set point display, with programming changes
easily performed via simple 3-button (key) operation.
The HP7 offers precise water temperature control, accurate defrost management, anti short-cycle
protection, circulator pump management, compressor contactor control, refrigerant circuit
pressure monitoring… all with solid-state reliability. The HP7 monitors water and refrigerant
temperatures using precise thermistor sensors. The control also features full diagnostics messages,
simplifying both installation and service.
Additionally, the HP7 offers maximum corrosion and vibration protection: All printed circuit
board interconnections are soldered, and the main Power Board and Display Board are specially
coated for added protection against humidity, air pollutants, and chlorine vapors.
The HP7 is an excellent alternative to electromechanical controls.

START UP & SETTING OPERATING CONTROLS
NOTE:
Covered within this section are features and settings typically accessed first by
the installer, and then remaining accessible by the end user (owner). These
features reside at the Level-1 access point within the microprocessor. (Please
see page-11 for information concerning Level-2, service-related access.)
1. Applying Power to The Controller:
A. When power is first applied, the control performs a lamp test and the display will read
[888]. Following [888], and with versions .04 and greater, the software version will
display briefly. Additionally, all status LED’s lights will illuminate for 4 seconds and
2. Turning The Heat Pump ON:
3. Turning The Heat Pump OFF:
4. Selecting Pool / Spa Thermostat Settings:
then go off for 1 second.
B. The control will then display the actual temperature as long as the pool-circulating pump
is on.
C. If the pool-circulating pump is off, the control will display the [FLO] (No Water Flow)
code message indicating water is not being circulated though the heat pump.
A. Once electrical power is supplied to the heat pump, the pool-circulating pump is
activated, and the control has successfully completed the self-test, the unit is ready to
operate.
B. The control is shipped with the SPA set point in the [OFF] mode and with the POOL set
point selected. The heat pump is automatically switched off if a set point below 60 °F
has been selected. In the [OFF] mode, the control will display the water temperature as
long as the pool water-circulating pump is operational. In the event water is not
circulating through the heat pump, the control will display the [FLO] (No Water Flow)
code message.
C. Using the Up ⇑ arrow key, increase the desired temperature until it exceeds the value of
the actual temperature displayed. (Note: See #8, below, if “000” is displayed upon
pressing up or down arrows.) Once the desired temperature has been entered, the display
will read the actual temperature and the heat pump will start to operate. Both the
compressor and fan must be operating before the “Heat” LED will illuminate.
A. Using the Down ⇓ arrow key, decrease the desired temperature until the display reads
[OFF]. The heater will shut off, and will remain off until the temp erature set point is
raised above 60° F.
B. NOTE: Each time the heater is turned off, either manually, or by the thermostat
becoming satisfied, there will be a 4-minute delay prior to restarting.
A. Depress the Pool / Spa key to toggle between the pool and spa temperature set points.
B. The pool / spa led indicator lights located to the left of the temperature display will
confirm the selected temperature set point.

5. Changing The Pool Temperature Set Point:
A. Using the Pool / Spa key, select the POOL temperature set point. The pool set point
indicator light will confirm your selection by lighting.
B. The pool temperature set point range is adjustable from 60°F. to 95° F (104 °F in latest
models). using the Up ⇑ or Down ⇓ arrow keys. The desired temperature can be selected
by briefly depressing the arrow keys, or by holding them down to scroll the temperature
up or down.
6. Changing The Spa Temperature Set Point:
A. Using the Pool / Spa key, select the SPA temperature set point. The spa set point
indicator light will confirm your selection by lighting.
B. The spa temperature set point range is adjustable from 60°F to 104°F by using the Up ⇑
or Down ⇓ arrow keys. The desired temperature can be selected by briefly depressing
the arrow keys, or by holding them down to scroll the temperature up or down.
7. Selecting Between °F And °C:
A. Depress both the Up ⇑ and Down ⇓ arrow keys simultaneously until [CF1] (Celsius /
Fahrenheit) code appears.
B. With the [CF1] code displayed, pressing either the Up ⇑ or Down ⇓ arrow key will
display either a (1) or (0). Select (1) for Fahrenheit temperature display or (0) for Celsius
temperature display. Once the desired temperature display has been selected, not
depressing any buttons for 15 seconds will allow the control to save the selection and
return to the normal operating mode. Pressing the Pool / Spa key will also save the
selection and step to the next menu parameter [ULC] (User Lock Code).
8. User Lock Code Option [ULC] :
This Option Explained:
Heat pumps are shipped from the factory with the ULC option disabled. Enabling the ULC
function permits the heat pump owner to restrict access to the unit controls. With the ULC
option enabled, unless the correct ULC lock code number is entered, changes to Level-1
programming are not possible (I.e.: Altering temperature set points, Pool/Spa selection, C/F
display changes, etc., will not be possible). The ULC option can be thought of as an
electronic lockable cover for the controls.
A. Selecting ULC Option:
1) Depress either of the Up⇑ or Down ⇓ arrow keys; if [000] is displayed, the ULC
feature is already enabled. If [000] displays, proceed to number “6)” of this section;
otherwise, see number “2” below;
2) Depress both the Up ⇑ and Down ⇓ arrow keys simultaneously until the [CF1]
display appears;
3) Depress the pool/spa key once, the [ULC] display will appear;
4) With [ULC] displayed, pressing either the Up or Down arrow key will display either
“1” or “0”. Selecting “0” will allow the control keypad to remain unlocked. Selecting
“1” will enable the User Lock Code option. Then, to enter a lock code number, press
the pool/spa key once. [ELC] (Enter Lock Code) will display;
