Nibe F1155 Series Installer Manual

Two or more climate systems
In buildings with several climate systems that require
different supply temperatures, the accessory
ECS 40/ECS 41 can be connected. A shunt valve then
lowers the temperature to the underfloor heating sys-
tem, for example.
Pool
By supplementing the installation with the accessory
POOL 40, pool heating is enabled in your climate unit.
During pool heating, the heating medium circulates
between the F1155 and the pool exchanger using the
heat pump’s internal circulation pumps.
Connecting hot water circulation
To reduce the risk of bacterial growth in systems with
hot water circulation, the temperature of the circulating
water should not fall below 50 °C. There should not be
any non-circulatory hot water pipes. Adjust the hot water
system so that the temperature does not fall below 50
°C at the ends of the system.
An additional expansion vessel may be requiered.
