4 Operation
4.1 Description
The Air Comfort is an advanced air heater for domestic use.
The air is heated using a heat exchanger. Depending on the discharge temperature, the system ventilator will
transport on a continuous scale less or more air through the appliance
A control unit with a microprocessor regulates and monitors the safe operation of the appliance. Using the
display and the control buttons, the setting values can be adjusted and the current measurement values, filter
messages and faults can be read.
4.2 Programme choice
The air flow can be automatically controlled using an internal temperature sensor and the selected programme.
The air flow can be influenced using an extra 4
‑
position switch.

(op pagina 47) for the other parameters to be set.
4.2.1 Constant programme
In the constant programme, the system ventilator operates as follows
▪
At a minimum air flow with a discharge temperature below 30°C (T_start). The minimum air flow and T_start
can be set with parameters
2
and
5
.
▪
At a variable air flow with a discharge temperature above 30°C (T_start), varying between a set minimum and
set maximum air flow. The maximum air flow is reached with a maximum discharge temperature (T_max) that
is to be set. The discharge temperature and the maximum air flow can be set with parameters
1
and
3
.
When heating is required, the system ventilator is controlled and the switch outputs for frost protection and
cooling are deactivated.
