Heat Pump Options
ThermoLink® Heat Exchanger
The heart of your heat pump is the patented ThermoLink® heat exchanger. One of the primary causes of premature heat pump demise is the failure of the heat exchanger. Ordinary heat exchangers are made from a cupronickel alloy. This cupronickel material is susceptible to attack from the sanitizers used in pools and spas and from other related water chemistry conditions. Once the heat exchanger fails, the heat pump is ruined. The ThermoLink® heat exchanger tube is made from titanium, and is virtually impervious to water chemistry damage.
Microprocessor Controller
Digitally-based microprocessor controls water temperature to within 1º Fahrenheit of set point. Controller also permits user to predefine different pool and spa water temperatures, and to prevent tampering by locking out controls via a pass code. The microprosser controller also provides superior defrost control, and self diagnostics.
Scroll Compressor *
50% fewer moving parts than standard piston-type compressors. This equates to much improved reliability and improved efficiency. Scroll compressors are also much quieter in operation than their piston-type counterparts. And, while all AquuaCal heat pumps are known for their low operating noise levels, if yours is a SuperQuietTM model, it’s very likely your heat pump will be quieter than any other item on the pool equipment pad.
Corrosion-Proof Cabinet
The cabinet, being made from resilient, UV-Protected ABS material, has superior fade resistance and can never rust or corrode. You can expect the cabinet to retain a likenew appearance with only an occasional wash down and—if so desired—a quick waxing.
Heat & Cool Capability**
Puts you in full control, year round... Warms your pool or spa with the reliability and efficiency of our other heat pumps, but, with the flip of a switch, can also cool your pool or spa to refreshing temperatures during hot summer months. For cooler climates, Heat & Cool heat pumps offer unique advantages over passive defrost models. Please read more below...
Hot gas defrost heat pumps are uniquely equipped for an active defrost cycle. Active defrost involves directing hot refrigerant vapor to the heat collector, melting accumulated ice away in a matter of a few minutes... then right back to heating. Standard defrost heat pumps may remain “off in defrost” for extended periods during very cold weather. Because of their ability to continue to operate–even during freezing weather–hot gas defrost models extend the swimming season longer than any standard-defrost heat
pump. * These features available in SuperQuietTM Models Only. ** These features available in Icebreaker® Models Only.
PLEASE READ FURTHER TO BECOME FAMILIAR WITH ALL THE FEATURES, THE SAFE
OPERATION, AND THE CARE OF YOUR NEW HEAT PUMP.

HOW A HEAT PUMP WORKS
THE FOLLOWING EXPLANATION IS PROVIDED TO HELP YOU IN UNDERSTANDING
WHAT TO EXPECT FROM YOUR HEAT PUMP…
A Heat Pump Does Not Make Heat…
Heat pumps are so extraordinarily efficient because they do not need to produce heat in order to warm pool or spa water. Rather, heat pumps simply transfer heat from the outside air into the water.
If one considers Absolute Zero (the point where all heat is absent) occurs at -459º Fahrenheit, it becomes evident outside air, even at the relative cool temperature of 55º Fahrenheit, still contains large amounts of heat energy. It is that abundant heat energy a heat pump captures and places into your pool or spa.

HEATINGQUICK START & STOP
This brief information is provided as an aid to installers, service personnel, and owners. The intent of this section is to provide rapid access to very basic operational information. Individuals who will be routinely using, installing, maintaining, and servicing this heat pump, are strongly encouraged to read this entire manual. Herein, the terms: Heat Pump, Heater, and Unit are used synonymously. These instructions are intended for local control of a heat pump, independent of an external controller. Owners: if your installation includes an external controller, contact your installing dealer, or the external controller manufacturer, for external controller operating instructions.
These instructions are for quick-starting in the HEATING mode... Owners of Heat-Cool units, in order to utilize all features of their heater, may want to also refer to: Owner Level Programming, beginning on page-14 of this manual.
1.Verify Electrical Power is Present at Heater:
A.Ensure that the unit has electrical power connected; the heater controller display should be illuminated.
B.If the display is blank, be certain the electrical breaker, and heater disconnect, are switched to “ON.”
C.For now, leave the water circulation pump OFF.
2.Set the Heater Controls (Refer to Control Panel Layout, Pg-12):
OWNERIf heater is connected to a Call-Flex controller, also see “Selecting Call-Flex Pump Options,” located on page-17 of this manual.
INSTALLERIs heater connected to an external controller? If so, see external controller information located on pages 41 and 44 of this manual.
A.The user/owner settings can be made without water flowing. Once the heater has electrical power connected, with water not flowing, the display should read FLO.
B.Press the MODE button until the HEAT (HEA) indication displays. This action will enable the remaining programming keys.
C.Using the POOL / SPA selector key, select the POOL mode. An illuminated POOL indicator light, located on the left side of the display, will confirm the POOL control has been selected. If heating only a spa, using the DOWN arrow key, lower the POOL temperature until OFF is displayed; then proceed to Step-“E.”
D.Use the UP / DOWN arrow keys to set the desired water temperature for the POOL water.
E.If the heat pump will be used to heat a spa, use the POOL/SPA selector key to select SPA, then use the UP / DOWN arrow keys to set the desired water temperature for the SPA. An illuminated SPA indicator light, located on the left side of the display, will confirm the SPA control has been selected. If heating only a POOL, using the DOWN arrow key, lower the SPA temperature until OFF is displayed.
F.The heat pump controls are now set to maintain the desired water temperature for the POOL and/or SPA.
10
HEATING-QUICK START & STOP (continued):
3.To Begin Heating:
A.Verify MODE is set to: HEAT (HEA); then, depending on which body of water is to be heated, use the POOL / SPA selector key to select POOL or SPA.
B.Position water valves to flow water from the pool or spa, through the heater, and back to the pool or spa.
C.Start the water pump; the fan will start, and after 4-minute time delay the unit will begin heating. The selected body of water will be brought to temperature and maintained per the setting determined previously in: “Set the Heater Controls.”
D.In operation, whenever the actual (displayed) water temperature falls below the desired set point, after an initial time delay of 4-minutes, the unit will begin heating.
NOTE: THE HEATER CONTROLLER INCORPORATES AN ANTI-SHORT CYCLE TIME DELAY. SHOULD OPERATION BE INTERRUPTED, COMPRESSOR RESTART WILL BE DELAYED BY APPROXIMATELY 4-MINUTES.
4.Program Filter Pump Run Time:
Most pool/spa systems utilize a timer or multifunction controller to manage filter pump run times. If your system incorporates such a device, follow the instructions below:
A.It will be necessary to allow the filter pump to run continuously until the water has reached the desired temperature. If a timer controls the pool filter pump, it will be necessary to override the timer to allow 24-hr. operation.
B.Once the desired temperature has been obtained (1-4 days), reset the pump control device. Colder months require longer running times - generally eight to twelve hours/day.
C.A heat pump can only operate when the filter pump is running. Therefore, it may be necessary–during cooler weather–to extend the water pump’s hours of daily operation. The increased run time is necessary in order to keep up with increased, weather-related heat losses.
5.Continuous Usage and Water Around Heater:
Condensation... After the heat pump has been operating for some time, water may be observed surrounding the heater. The moisture seen is condensation produced as a normal by-product of transferring heat from the air into the pool or spa water. Quantities of 6-8 gallons of water produced per hour are common if the air humidity is high. Conversely, a low humidity condition may result in no condensation being produced. (If water around unit seems excessive, to troubleshoot, see page-26, “Water Coming from the Heat Pump.”)
6.To Stop the Heat Pump:
A.Select: OFF via the MODE selector. This method of shut down preserves the controller settings;
B.An interruption of water flow–such as when a pump timer is in control–will also halt heat pump operation.

HEATER CONTROLS...continued
Start Up & Setting Operating Controls
Owner-Level Programming Instructions
This section covers features and settings topically accessed first by the installer, and also accessible to the owner/operator. These features reside at the Level-1 access point within the microprocessor. Note: if preferred, all programming may be performed without water flow, waiting to start the water pump as the last step in the set up and run process.
1.Applying Power to The Controller:
A.When power is first applied, the controller performs a lamp test and the display will read [888]. Following [888] the software version will display briefly.
B.The control will then display the actual water temperature, provided the circulating pump is operating, and adequate water is flowing through the heater.
C.If the pool-circulating pump is off, the control will display: [FLO]. This code message indicates no (or insufficient) water is being circulated through the heat pump.
2.MODE Controls Explained, and Starting the Heat Pump
Once electrical power is supplied to the heat pump, sufficient water is circulating, and the heater controller has successfully completed its self-test, the heater is ready to operate. The heat pump has four controller operating "Modes"; OFF, HEAT, COOL*, and ACH* (Auto-Change Over).
OFF - The heat pump is shipped in the OFF mode. When the heat pump MODE is set to OFF, the current water temperature will be displayed and no functions, values, or programming will be available for adjustment. If there is insufficient water flow, the unit will display FLO.
HEAT - To turn the unit on in heat only mode, press the mode button to HEAT. The display will show the actual water temperature. Press the UP ARROW key to set the desired temperature. After the desired temperature is set, the unit will again display the actual water temperature. If the set temperature is above the actual water temperature, the heat pump will start and continue to heat until the desired temperature is reached. The heat pump will periodically turn on, calling for heat as needed in order to maintain the set temperature until the mode is changed back to OFF. PLEASE NOTE - both the compressor and the fan must be operating before the “Heating” LED will illuminate.
COOL* - To turn the unit on in cooling mode, press the mode button to COOL. The display will show the actual water temperature. Press the UP ARROW key to set the desired temperature. After the desired temperature is set, the unit will again display the actual water temperature. If the set temperature is below the actual water temperature, the heat pump will start and continue to cool the water until the desired temperature is reached. The heat pump will periodically turn on to cool the water as needed until the mode is changed back to OFF.
ACH* - To have the heat pump maintain a particular temperature, regardless of the temperature of the water, press the mode button to ACH. The heat pump will turn on in either heat or cooling mode to maintain that temperature as needed until the heat pump mode is changed to OFF.
3.Turning The Heat Pump Off:
A.Method 1: using the [MODE] key, press the key until the display reads “OFF” The heater will shut off and remain off until the [MODE] key is used to select an operational mode. This is the preferred method for shutting off the heat pump.
*These features available in Icebreaker® Models Only. |

B.With the [CF1] code displayed, pressing the [UP ARROW] or [DOWN ARROW] keys will change the selection code to either “0” or “1”. Select “1” for Fahrenheit temperature display, or “0” for Celsius temperature display. Once the desired temperature display mode has been selected, not pressing any buttons for 15-seconds will allow the controller 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’s controls. With the [ULC] function enabled, unless the correct ULC 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.

3)In addition, all other settings are returned to the factory defaults. If an external controller is in use, contact AquaCal Technical Support Group (727-823-5642); ask for assistance with re-configuring the controller for use with an external controller.
9.Selecting Call-Flex Pump Options [CFO]:
General Information:
The Call-Flex option automatically extends or overrides the run time of the water circulator pump, and heater, based upon changing weather conditions. Without Call-Flex, as weather conditions grow progressively cooler during winter months, or when unusually cold weather occurs, the run duration of the circulator pump may require manual adjustments to permit the heater to maintain or reattain desired water temperature (the water pump must be running in order for the heater to operate). Likewise, without Call-Flex, one must remember to reset the pump run controls following the cold weather event. The Call-Flex option greatly reduces the need for seasonal, manually made, pump run time adjustments. Call-Flex is a dealer-installed option that does not come with every heater; if unsure, check with the installing dealer to determine if a call-flex kit was part of the original installation. If Call-Flex was not part of the installation, and you would like to have Call-Flex added, your dealer can do so...contact the installing dealer.
If the installation is equipped with the Call-Flex option, the following steps are used to control the Call-Flex features:
A.Simultaneously press and hold the [UP ARROW] and [DOWN ARROW] keys until the display shows “CF1”. Press the [POOL/SPA] key three times to scroll the display to [CFO].
B.With the [CFO] (Call-Flex Options) code displayed, use the Up or Down keys to select “0” to disable the Call Flex Options, “1” to enable the Call Option, or “2” to enable the Flex Option. Not pressing any buttons for 15-seconds will allow the controller to save the selection and return to the normal operating mode. Pressing the {POOL/SPA] key will also save the selection, and will step the controller to the next menu parameter: [LOC] (Service Lock Code).
C.For further information, please refer to Call-Flex installation instructions, shipped with the Call-Flex kit. For additional copies of these instructions, contact the AquaCal Customer Support (727-823-5642).

MAINTENANCE
&
OPERATIONAL RECOMMENDATIONS
The information in this section is written primarily for the Home Owner, but may also apply to servicing dealers or HVAC service centers. This section contains information concerning planned maintenance, proper water flow, maintaining proper clearances, as well as other vital information. Please read this section now, and before calling AquaCal Customer Support (727-823-5642).
General Maintenance
Heat pumps should be inspected and maintained on an annual basis by a qualified swimming pool heat pump specialist. Additionally, if the heat pump is located near the beach or coastal area, where salt spray and sand can become detrimental factors, more frequent service may be necessary. For service plan information, please see: Planned Maintenance Program, later in this section, and then contact AquaCal Customer Support at: 727-823-5642.
While annual maintenance is recommended to maintain your warranty, if you choose not to participate in the Planned Maintenance Program, rinsing the air coil regularly, and keeping the base of the unit clear of leaves and debris is a necessity.
Should you as the owner desire to perform the coil rinsing and other cosmetic care of the heat pump, please contact AquaCal Customer Support: 1-727-823-5642; request the document titled: “Appearance Care for Air-Source Heat Pumps: Approved Method for Home Owners.”
