It is important that this manual is read carefully by both the installers and users to ensure the heat pump’s function and lifetime.
Pahlén AB is not responsible for any damage due to improper installation, mishandling or improper maintenance.
Product description
Pahlén heat pump Calidi XP is intended for heating the swimming pools or whirlpools. It is intended for operation at air
temperatures between –7°C and + 43°C to obtain 18–40°C of the pool temperature (maximum power is achieved at the air
temperatures b15°C and +25°C). The heat pump has built-in Wi-Fi.
Heat pump e昀케ciency is in昀氀uenced among other things by water, air and pool temperatures. On cold days and nights,
the operating time required to obtain the desired temperature in the pool becomes longer than on hot days. For economy
reasons it is better to cover the pool when not in use, especially at nights. Approximately 60–70% of the heat is lost through the
pool water surface. Covering the pool therefore reduces the heat pump operating time.
Key functions
This heat pump is equipped with safety functions that automatically stop the operation in order to protect the heat pump.
The display shows the current pool temperature, or an error code if an error occurs.
Flow switch
The 昀氀ow switch is turned on when a su昀케cient 昀氀ow of pool water 昀氀ows through the heat pump’s titanium heat exchanger .
At low 昀氀ow or no 昀氀ow, the heat pump shuts o昀昀, and the display shows “E3” error code.
When the 昀氀ow returns to normal, the heat pump restarts automatically.
High and low pressure guard
Protects compressors. The pressure switch can detect the refrigerant circuit pressure at high pressure/ low pressure sides and
turn o昀昀 the heat pump at too high/low pressures.
If the pressure switch detects a too high pressure, the display shows “E1” error code.
If the pressure switch detects a too low pressure, the display shows “E2” error code.
When the pressure returns to normal, the heat pump restarts automatically.
Low outdoor temperatures
The heat pump automatically shuts o昀昀 if the outside temperature is too low for the pump to produce heat.
The display shows “Eb” error code. Heat pump restarts automatically when the outdoor temperature becomes too high.
The exact temperature for disconnection varies depending on the current weather (and the amount of sunlight), and activates
the temperature sensor positioned on the heat pump back side.
Restart delay
Heat pump has a 3-minute restart delay (to prevent the compressor thermal overloading caused by the refrigerant pressure
being not balanced, which can occur at short starts and stops).
Operating mode
Heat pump has two di昀昀erent operating settings: “Full power” and “Eco”. They have di昀昀erent advantages in di昀昀erent situations.
Full power:
The operation is automatically adapted to the air and water temperatures in order to quickly heat the pool to the desired
temperature. Recommended during the heating phase:
Eco:
Heating capacity between 25 and 80%, noise level 3% lower than in the “Smart” operating mode.
Recommended at night or when the pool has the required temperature, and the ambient temperature is at least 15°C .
