The section of the pipe that can be affected by frost must be heated by the heating cable to prevent freezing. Route the pipe downward from F2026. The outlet of the condensation water pipe must be at a depth that is frost free or alternatively indoors (with reservation for local ordinances and regulations).
The condensation water pipe must have a water trap to prevent air circulation in the pipe. Installation area The distance between F2026 and the house wall must be at least 350 mm. Clearance in front of F2026 should be at least one metre. utrymme Fritt utrymme framför NIBE™...

F2026 (slave) can be connected to VVM 300 (master). F2026 is then controlled by VVM 300 and works with floating condensing to the heating system and prioritises hot water charging in VVM 300.
VVM 500 F20XX F2026 (slave) can be connected to VVM 500 (master). F2026 is then controlled by VVM 500 and works with floating condensing to the heating system and prioritises hot water charging in VVM 500. If F2026 cannot supply the whole heating requirement the additional heat is supplied from VVM 500.

Additional heat can be blocked above the set balance temperature by means of the automatic control system in F2026. In other cases the heat pump does not collab- orate with the electric/oil fired boiler in the optimum way. Hot water production only takes place using the existing electric/oil boiler.

The following image displays the recommended cable routing from the electrical cabinet to the condensation water trough in F2026. The transfer from electrical cable to heating cable must occur after the lead-in to the con- densation water trough. The distance between the elec- trical cabinet and the lead-in to the condensation water trough is approx.1930 mm.
