6.3 Air-conditioning
You can expand the appliance with cooling. A cooling
unit must then be installed outside and an evaporator
must be installed inside on top of the Udara air heater.
This ensures that you can distribute cold air through
the ducts during the summer months.
The RC21 thermostat can be used to switch on the
cooling unit.
6.4 Heat
pump
You can also expand the appliance with a heat pump.
You can then use the heat pump to cool in the summer
and to heat in the seasons in-between.
The gas burner will then only be used if the outside is
colder and the ef
fi
ciency of the heat pump becomes
too low or if too many thawing cycles occur.
If you want to connect a heat pump, you must opt for a
thermostat of the Multicalor Verventa range. For more
information please contact us free from obligation.
6.5
Operation in heating mode
The operation of the air heater can be summarised as
follows in normal use:
•
If there is a heat demand, the appliance will ignite
the burner. The fan will be started on a minimum
air
fl
ow rate.
•
The RC21 thermostat will measure the difference
between the set and the current room temperature
and will increase or decrease the air temperature
based on this data.
•
The air heater modulates the burner to achieve the
set air temperature as best as it can.
•
The system fan will adjust the air
fl
ow rate to the
current discharge air temperature.
The air
fl
ow rates and air temperatures can be set by
using the control panel.
6.6
Setting as ventilation
If required, you can set the fan in the appliance to a
fi
xed air speed on the RC21, for example, during the
summer months.
This can be considered as a set minimum
fl
ow rate,
that is, the control can make the fan turn faster but
never slower. You can select between 4 different
settings.
6.6.1 Ventilation
off
The fan will only operate if there is a heat demand. If
there is no heat demand, the fan will not be
operational.
6.6.2 Ventilation
low
The fan will always operate at the set low air speed
even if there is no heat demand.
6.6.3
Ventilation à vitesse moyenne
De ventilator draait steeds op de ingestelde middelste
luchtsnelheid, ook indien er geen warmtevraag is.
6.6.4
Ventilation à haute vitesse
De ventilator draait steeds op de ingestelde hoge
luchtsnelheid, ook indien er geen warmtevraag is.
6.7 Het
bedieningspaneel
Op het toestel is een bedieningspaneel aangebracht
dat toelaat om de verschillende instellingen van het
toestel te wijzigen. Het bedieningspaneel is voorzien
van een capacitief aanraakscherm en een TFT kleu-
