Putting heat pump into operation
Note! Pool system CIRCULATION PUMP should always BE STARTED BEFORE THE HEAT PUMP.
Do the following:
1. Check that the heat pump and pipe connections are installed according to the pipe laying diagram.
2. Check the installation against the wiring diagram and that grounding is correct.
3. Check that the heat pump operating switch is turned off.
4. Start the pool system circulation pump.
5. Check that there are no water leaks in the system.
6. Check that the pump air inlet and outlet are not blocked.
7. Turn on the operating switch for the heat pump and check that the heat pump control panel lights up (current pool
temperature is shown in the display window).
8. Start the heat pump by pressing the On/Off button on the heat pump control panel (Lamp 1 lights).
At the pump start, time delay activates in order to protect the heat pump: in 3 minutes the heat pump fan activates,
and in 30 seconds the compressor starts working (Lamp 2 lights).
9. Check the heat pump temperature setting / Set the appropriate temperature, see below.
10. Check that no unusual noises are coming from the heat pump when it is in operation.

Setting the desired water temperature

Setting the water temperature can be done regardless of whether the heat pump is operating or not.
Press ▲ or ▼ to set the required temperature.
In order to check the settings, press ▲ or ▼. The desired temperature is displayed as a blinking light.
After the required pool temperature is obtained, the heat pump will adjust it once an hour. Heating will start again after the
controls detect that the temperature has fallen by 1°C (below the set value)

Controlling and adjusting the water flow

• Adjust to the recommended water flow through the heat pump by means of valves in the bypass kit 14950181 or another pipe
laying pattern.
• Let the heat pump run for at least for 5 minutes.
• Hold the MODE button for 10 seconds. Check parameters C0 ( = incoming water temperature ), resp. C1 (= outgoing water).
Shifting of the parameters is done with the arrow keys. The difference for optimal efficiency should be between 1– 3°C.
Open the bypass valve in order to increase the difference or the throttle valve to reduce the difference.
Leave the parameters menu by the On/Off button or wait a while, since the pump returns to a normal view automatically.

Mode selection

Heat pump always starts in a "Smart" mode indicated by the "Smart" lamp.
Press the "Mode" button to change the operation mode. The current operating mode is indicated by a lighting lamp in the "Start"
or "Silent" mode.
