8. Troubleshooting

The water pump is fitted with the following safety 

equipment:

8.1 High-pressure switch : 

The high-pressure switch protects the heat pump from 

excessive pressure in the cooling circuit. In the event of 

any disturbances (excessive pressure), the high-pressure 

switch will stop the pump. The system will restart when 

the high-pressure switch is reset manually. Take off the 

front cover by removing the screw. 

Press the red button for RESET. 

8.2 The device is not running 

The device stops: 

Check the following: 

Is the device connected to a power supply (230 Volt)? 

• 

Is there power in the socket? 

• 

Is the heat pump disconnected via the clock 

• 

program? 

Is the high-pressure switch disengaged? 

• 

Is the cable attached between the control system and 

• 

the control panel? 

Has the filter not been changed (“Filter error” on the 

• 

device)? 

Water frost error. 

• 

Condensation water is leaking from the device: 

Error: 

Condensation outlet blocked with dirt. 

• 

The condensation outlet is not adequately protected 

• 

against freezing at low outdoor temperatures. 

8.3 Error on air side

No air extraction from wet rooms: 

Error: 

Defective fan. 

• 

Blocked plane filter. 

• 

The fuse on the control system circuit board has 

• 

blown. 

Discharge grill/roof cover blocked by snow and ice in 

• 

winter. 

Cold air supply: 

Error: 

The heat exchanger is blocked by snow and ice. 

• 

The extraction fan is defective. 

• 

The extraction filter is blocked. 

• 

The cooling surface is blocked with ice. 

• 

The cooling component in the cooling circuit (Heat 

•
