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.
The programme choices are:
▪The constant programme (op pagina 14)
▪The fixed programme (op pagina 16)
▪The HRU programme (op pagina 17)
The appliance is delivered from the factory set on the constant programme.
Use parameter 9in the Setup menu (op pagina 29) to activate the desired programme. See the Parameter list
(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 2and 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 1and 3.
When heating is required, the system ventilator is controlled and the switch outputs for frost protection and
cooling are deactivated.

In the constant programme, the control of the system ventilator can be influenced by a 4-position switch.
▪ Position 1 - at temperatures below 30°C, the system ventilator always continues operating at the set minimum
air volume. At temperatures above 30°C, the air flow varies between the set minimum and the set maximum
air flow depending on the measured discharge temperature.
▪ Position 2 - the system ventilator is switched off if the discharge temperature falls below a set switching
temperature. If the temperature of the heat exchanger increases above this adjustable value, the system
ventilator is activated again. At temperatures above 30°C, the set minimum and the set maximum air flow
varies depending on the measured discharge temperature. The temperature for switching on and the
temperature for switching off, as well as the hysteresis of the switching temperatures for the ventilator can be
set with parameters 6, 7and 8.

A cooling demand through a closed switch input 'cooling' has priority over the position of the 4-position switch of
the heat recovery unit.
The CO2sensors that are connected to the heat recovery unit have no influence on the control of the Air Comfort.
Air Comfort 614788-B

4.3 CO₂-control
A maximum of 4 CO2sensors can be connected to the Air Comfort. These CO2sensors help to maintain the air
quality of the separate rooms to which the Air Comfort is connected.
The CO2sensors have a minimum and maximum setting value. If the CO2concentration in a room gets above the
minimum setting value, the air flow of the system ventilator of the Air Comfort increases. The air flow varies
depending on the measured CO2concentration(s). The air flow to be supplied is based on the room (CO2sensor)
with the highest CO2concentration.
Important
The CO2control only works if the 4-position switch is on position1 or if no 4-position switch is
connected.!

2. CO2[PPM]
3. Air flow-max [m3/h]
4. Air flow-min [m3/h]
5. Min CO2[PPM]
6. Max CO2[PPM]
When heating is required from the Air Comfort appliance with CO2sensors the air flow is determined by the air
discharge temperature or the CO2sensors. The one with the highest demand determines the regulation of the air
flow.

4.4 Frost protection
The frost protection ensures that the heat exchanger does not freeze in the event of frost.
The frost protection is controlled by the discharge temperature sensor:
▪When the temperature is lower than a set temperature limit 1, any heating demand is blocked by cutting the
'cooling' switch output. The frost protection and the present external heat source is activated. The system
ventilator is controlled on the basis of the measured air discharge temperature and, if applicable, the position
of the 4-position switch.
Use parameter 10 in the setup menu (op pagina 29) to set the switching temperature.
▪When the air discharge temperature with a set hysteresis has risen above 1, the blocking of the cooling
demand is lifted again. The frost protection is deactivated.
Use parameter 12 in the setup menu (op pagina 29) to set the hysteresis.
If the discharge temperature, despite the frost protection, decreases further than the switching temperature limit
1 to a set switching temperature limit 2, the system ventilator is also switched off.
Use parameter 11 in the Setup menu (op pagina 29) to set switching temperature limit 2.
The blocking of the system ventilator is lifted in the following way:
▪If the air discharge temperature increases by 5 ºC compared with the switching temperature limit 2, the
system ventilator is activated for a fixed period of time (anti-pendulum time). The system ventilator continues
to run on the basis of the position of the 4-position switch as long as the set time has not yet been exceeded.
▪If the water temperature in the heat exchanger rises above a set switching temperature (parameter 6), the
system ventilator is activated. The system ventilator continues to run on the basis of the position of the 4-
position switch.
▪If [R] on the control panel is pressed, the system ventilator is activated for a fixed period of time (anti-
pendulum time). The system ventilator continues to run on the basis of the position of the 4-position switch as
long as the time has not been exceeded.
