CONVECTOR
Works in the same way as a radiator, but with the difference that the air
is blown out.
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 electric boiler/indoor module can sometimes be
noticed as a disturbance in comfort.
In most cases, the electric boiler/indoor module notes a malfunction and
indicates this with alarms and shows instructions on how to rectify it in
the display.
DOMESTIC HOT WATER
The water one showers in for example.
DOT, DIMENSIONED OUTDOOR TEMPERATURE
The dimensioned outdoor temperature differs depending on where you
live. The lower the dimensioned outdoor temperature, the lower the
value should be selected on "selecting a heat curve".
ELECTRICAL ADDITION
This is the electricity that, for example, an internal immersion heater
uses to cover the heating demand that the heat pump cannot manage.
EMERGENCY MODE
A mode that can be selected using the switch if there has been a fault
that means that the electric boiler/indoor module is not running. When
the electric boiler/indoor module is in emergency mode, the building is
heated using an immersion heater.
EVAPORATOR
Heat exchanger where the refrigerant evaporates by retrieving heat en-
ergy from the air which then cools.
EXPANSION VESSEL
Vessel with heating medium fluid with the task of equalising the pressure
in the heating medium system.
