Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low or
if the indoor temperature is not at the desired level.
A malfunction in the heat pump can sometimes be noticed in the form of a
disturbance in comfort.
In most cases, the heat pump notes operational interference and indicates
this with alarms and shows instructions in the display.
Domestic hot water
The water one showers in for example.
Electrical addition
This is the electricity that, for example, an immersion heater produces when
the compressor's output is not sufficient to fulfil the property's heating de-
mand.
Emergency mode
A mode that can be selected using the switch in the event of a fault, which
means that the compressor stops. When the heat pump is in emergency
mode, the building and/or hot water is heated using an immersion heater.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the air which then cools.
Exhaust air
The air that comes from the exhaust air device in the various rooms of the
accommodation, to F750.
Exhaust air devices
Vents, usually in the ceiling, in the kitchen/bathroom/clothes closet where
the air is drawn in to be forwarded to F750.
Expansion valve
Valve that reduces the pressure of the refrigerant, whereupon the temperature
of the refrigerant drops.
