A circulation pump controlled by the heat pump will not activate as needed.
RESOLUTION
Confirm circulation pump is receiving power.
Reset circulation pump power breaker to allow internal pump faults to clear.
Confirm circulation pump is included in any group that requires it. See options manuals for help on using circulation pumps and creating groups.
Confirm the group containing the circulation pump has an appropriate schedule. See options manuals for help on using circulation pumps and creating schedules.
When ice starts to form on the coil, the compressor will stop operating while the fan continues to operate.
The coil will begin to warm to the surrounding air temperature. When the coil's temperature rises above 38° F (3.3° C), the compressor is restarted and heating resumes.
If the coil's temperature remains below 38° F (3.3° C), the compressor will remain off.
Heat and Cool Units - Active Defrost
Hot refrigerant gas will be sent through the coil to rapidly remove ice or frost.
During this process, the melting of the ice may appear as steam coming off the heat pump. This is normal.
The heat pump has sensed the air temperature has dropped below 37° F (3° C). This is the default setpoint before the heat pump begins to circulate water to groups marked as needing freeze protection. The heat pump will not heat water in these conditions. See "Freeze Protection" for more information.
NOTICE
Failure to heed the following may result in damage to equipment.
Freeze protection is meant to be temporary. If freezing temperatures will continue for an extended time frame, the pool equipment must be winterized.
Note
The freeze protection feature's "protect on setpoint" can be manually changed from (33° to 39° F (.6° to 4° C). The default is 37° F (3° C)
Please Note:
This protection is only available for heat pumps that directly control a circulation pump.
If heat pump is using a PoolSync®, confirm the device is connecting to the internet. It will automatically attempt to load firmware on the heat pump. See PoolSync® manual for specifics.
Low or no water detected. This is normal when the circulation pump is deactivated.
RESOLUTION
Confirm the filter pump is on.
If a multiple-speed filter pump is being used, run at a higher speed to determine if the error persists. Do not exceed the maximum flow rate for your model.
Confirm water is not being diverted away from the heat pump.
When pushing the POOL / SPA button, the heat pump displays the message "NO POOL/SPA GROUP EXISTS".
RESOLUTION
In order for this button to be active, a Pool Group, Spa Group, or both, must be created; either using a preset option or manually.
Note
The standard (from the factory) heat pump does not have a group or schedule. These can be created as needed depending on if a heat pump option has been utilized. See Product Manual Options for more information on available options.
Internal WiFi has been activated, but the heat pump cannot access the cloud (internet access).
RESOLUTION
Confirm that the heat pump has successfully connected to the home's WiFi access point.
Has setup been successfully completed? If not, this is a message that shows in the setup process and will go away when setup is completed. Please wait until is complete.
This may be a home internet issue. Confirm that the user's internet is active and that the user's WiFi access point is working.
Possible issue with the external cloud service. Wait for one hour. If issue continues, contact installing dealer for service. For further assistance, please contact AquaCal.
If when pressing the "Pool / Spa" button the display flashes the message "SET TO SWITCH REMOTELY", the heat pump is using a remote relay switch or a 3-wire controller.
RESOLUTION
The Pool and Spa thermostat automatically switch when using these modes.
Operation manually will not be available when using these external devices. No action is required.
If AquaCal®heat pumps have been connected using a multiple heat pump configuration, the configuration may be incorrect. Please confirm settings or contact installer of equipment.
Have an electrician confirm breakers are correct type, in good condition, and properly sized for the heat pump.
Confirm the heat pump has reached the desired temperature set on the thermostat. The heat pump will continue to run until the set temperature is reached.
If the heat pump is still not running correctly with this device, contact the installer of the device or the device’s manufacturer for further assistance.
Confirm heat pump mode is set to heat.
Confirm thermostat is set higher than the current water temperature.
Confirm valves are positioned to heat the correct body of water (either the pool or the spa). If heating a spa that overflows into a pool, confirm the spa is isolated when being heated (not flowing into the pool).
Confirm heat pump is transferring heat into the water.
Measure the temperature of air discharge coming out of the heat pump fan. If discharge air is between 8° to 16° F (-13° to -9° C) colder than the outside ambient air, the heat pump is moving heat into the water.
If an error code is displayed, diagnose and correct cause of code.
If heating a spa, deactivate air blower or venturi (if equipped) to allow for quicker heating times. For pools, deactivate water features, such as slides, waterfalls, or fountains to allow water to retain heat. Use of a liquid pool blanket product, such as an Aqua Blanket™, can also compensate for excessive heat loss.
Confirm the thermostat is set below the current water temperature.
Confirm valves are positioned to cool the correct body of water (either the pool or the spa). If cooling a spa that overflows into a pool, confirm the spa is isolated when being cooled (not flowing into the pool).
If an error code is displayed, determine and correct the condition causing the code.
Confirm heat pump is transferring heat out of the water.
Measure the temperature of air discharge coming out of the heat pump's fan. If the air is between 8° to 16° F (-13° to -9° C) warmer than the outside ambient air, the heat pump is moving heat out of the water.
Confirm that the filter pump has a sufficient run-time. The heat pump will not run (or cool the water) without water flow.
If heavy ice (not frost) starts to build up, shut off the heat pump. Contact the installer or manufacturer.
If the ambient air temperature will be falling below 32° F (0° C) for more than 8 hours, winterize equipment.
Cool Only Units
The heat pump may enter defrost mode if the water flow rate falls below the acceptable range. See "Water Flow Rates".
If the ambient air temperature will be falling below 32° F (0° C) for more than 8 hours, winterize equipment.
Heat and Cool Units (with Active Defrost or “Icebreaker”):
During freezing conditions, pool or spa heating will continue. Frost or ice may develop during the “countdown” to the active defrost (up to 50 minutes). This is normal. See "Displays Defrosting".
The heat pump will enter an "active defrost" stage to remove the accumulated frost and ice.
Be sure to observe the unit for at least 50 minutes. If it has not entered an active defrost cycle, call for service.
TIP:
The heat pump can be manually defrosted by temporarily switching to the cooling mode until the ice or frost melts.
If the ambient air temperature is (or will be) falling below 32° F (0° C) for more than 8 hours, winterize equipment.
The "Pool / Spa" button is disabled if the following devices have been configured on the heat pump. Check with installer if unsure of devices enabled on heat pump.
A 2-wire external controller.
A 3-wire external controller.
A "SMART" external controller.
An external flow switch.
RESOLUTION
If not used to operate the heat pump, deactivate the external control device.
Confirm the time is set correctly in the system. See equipment manual for information on changing date and time on heat pump.
Note
The standard (from the factory) heat pump does not have a group or schedule. These can be created as needed depending on if a heat pump option has been utilized. See Product Manual Options for more information on available options.
The water may be normal condensation produced as a by-product of the heat pump's refrigeration process.
The heat pump can produce up to 8 to 10 gallons (30 to 38 liters) of condensation per hour depending on the humidity of the ambient air. Determine if the water is condensation or a possible leak.
RESOLUTION
Deactivate heat pump, leaving the filter pump on. After several hours, determine if the water is still coming from the heat pump.
If using chlorine or bromine as a pool/spa sanitizer, test the water around the heat pump using a test strip. If the test strip indicates that chlorine or bromine is present, a leak may exist.
Please note -
If desired, a kit is available to re-direct condensation water away from the heat pump.
