Underfloor heating with an external heat supply pump
If heat pump's internal heat supply pump is insufficient to
underfloor heating, an external heat supply pump is to be
installed. The pump has to be dimensioned to correspond
to demand of underfloor heating system.
NOTE! Ensure pump's minimum flow with bypass valve
or by leaving sufficient amount of open circuits in heating
network. Refer to Technical specifications -table for pump
specific minimum flows.

Connecting an heating convector post-heating radiator
The ground source heat pump can be supplemented with
an accessory QiIV1, which enables connection of post-
heating radiator of water-circulating air convector. This
prevents post-heating radiator to freeze during domestic
hot water charge. Check the maximum flows and the post-
heating radiator's power levels in the technical
specifications.
Mounting of installation set (with or without a pump)
Installation sets sold as accessory for heat pump ease and
speed up the installation. This guide to connecting applies
to both sets – with and without a pump.
