INSTALLATION

 Bypass Valve Adjustment

If a bypass is installed, optimize heating efficiency as follows:

 Step 1: Set the bypass valve to 50% open.

 Step 2: Gradually adjust the valve to the lowest flow rate that does not trigger

a E03 “Water Flow Protection” error.

 Temperature Differential : The difference between Inlet and Outlet water

should be 1–5°F. If the difference exceeds 5°F, increase the water flow through

the heat pump.

Higher water flow does not equate to more heat. BluePlenum heat pumps are engineered

to operate within a specific flow rate range to ensure optimal heat transfer, maximum

efficiency, and long-term system reliability.

5. Completion: Ensure all connections are secured with PVC adhesive and checked for leaks

before operating the system.

heat pump will execute commands from both sources simultaneously.

Example Scenario: If your Control Panel is scheduled for 6:00 PM – 8:00 PM and your App

is scheduled for 5:00 PM – 9:00 PM, the unit will operate as follows:

5:00 PM: The unit receives an "On" command from the App and begins operation.

6:00 PM: The unit receives an "On" command from the Control Panel and remains running.

8:00 PM: The unit receives an "Off" command from the Control Panel and stops working.

9:00 PM: The unit receives an "Off" command from the App and remains off.

The unit runs from 5:00 PM – 8:00 PM. We recommend using the Tuya Smart APP to

manage all timer settings.

Restart Hysteresis

(Temperature Differential)

This parameter determines the temperature

deviation required for the unit to restart after

reaching its target. It prevents frequent

cycling and protects the compressor:

1) In Heating Mode: If set to 2°F, the unit

will remain on standby until the pool

water cools by 2°F below your target

temperature before turning back on.

2) In Cooling Mode: If set to 2°F, the unit

will restart only after the pool water

temperature rises 2°F above your target

temperature.

2-36°F

Stop Hysteresis

(Over-temperature Offset)

This parameter defines the temperature

"overshoot" allowed before the unit stops,

ensuring the water temperature is fully

stabilized:

1) In Heating Mode: If set to 1°F, the unit

will continue running until the pool water

2-36°F

reaches 1°F above your target

temperature before shutting down.

2) In Cooling Mode: If set to 1°F, the unit

will continue running until the pool water

reaches 1°F below your target

temperature before shutting down.

Auto Hysteresis

(Mode Switching Buffer)

This setting determines the temperature

threshold for the unit to switch between

heating and cooling when operating in "Auto"

mode:

1) To Start Cooling: If set to 3°F, the unit

will only switch to cooling mode once the

water temperature rises 3°F above your

target setpoint.

2) To Start Heating: If set to 3°F, the unit

will only switch to heating mode once the

water temperature drops 3°F below your

target setpoint.

3) Note: This buffer prevents the system

from "fighting itself" by constantly

switching back and forth between

modes.

2-36°F

To save electricity, the water pump will pause once the target temperature is reached. The

Constant-Temp Pump Run Cycle determines how often the water pump wakes up to

check the water temperature, while the Constant-Temp Pump Run Time sets how long

the pump runs during each check.

Note: The two parameters only apply when the water pump is wired directly to the heat

pump terminals.
