Nibe F110 - Ventilation Flows (Exhaust Air); Adjusting Ventilation (Exhaust Air); Dimensions and Ventilation Connections

Ventilation flows (exhaust air)
Connect F110 so that all the exhaust air, except kitchen duct
air (kitchen fan), passes through the evaporator (EP1) in the
heat pump.
The ventilation flow must comply with the applicable national
standards.
For optimum heat pump performance, the ventilation flow
must not be less than 20 l/s (73 m³/h) at normal exhaust air
temperature. At lower exhaust air temperatures, a higher
flow is required.
Set the ventilation capacity in the heat pump’s menu system
(menu 5.1.5 - "fan sp. exhaust air").
If the exhaust air temperature falls below 10 °C or the out-
door air temperature falls below -10 °C, the compressor is
blocked and electric additional heat is permitted. Energy is
not recovered from the exhaust air/outdoor air, when the
compressor is blocked.
Adjusting ventilation (exhaust
air)
To obtain the necessary air exchange in every room of the
house, the exhaust air devices must be correctly positioned
and adjusted and the fan in the heat pump adjusted.
Immediately after installation adjust the ventilation so that
it is set according to the projected value of the house.
Incorrect adjustment of the ventilation may lead to reduced
installation efficiency and thus poorer operating economy,
a poorer indoor climate and moisture damage in the building.
