ALARM
This menu is empty when the unit is operating
normally. If there is an active fault state in the
system, an associated alarm text is displayed
on this menu (see "Alarm").
If there has been a disruption in the system,
but this has disappeared, the menu shows a
message that can be acknowledged. An ac-
tive alarm cannot be acknowledged (see 3.1,
"Alarms").
TEMPERATURE
The temperature setting is only available
in models that are equipped with the air
heater for reheating.
The user sets the required value for minimum
supply air temperature, and the ventilation
unit then strives to reach this temperature if
possible. Swegon recommends that the supply
air temperature is set between 15–20 °C and
the factory setting is 17 °C, which is sufficient
for draught-free ventilation. The supply air
temperature should be 3–4 °C lower than
the room temperature, so that the supply air
mixes fully with the room air.
Remember the following when setting the
supply air temperature:
• A high temperature setting will also
increase the ventilation unit's power
consumption.
• A low temperature setting, for example,
14 °C, can cause condensation to collect in
the system.
• The ventilation unit cannot cool the supply
air without an air cooler (duct coil), which
is available as an accessory.
Commissioning and setting the external air
heater/air cooler, available as optional equip-
ment, are described in the installation, opera-
tion and maintenance instructions for the air
heater/air cooler.
