Room correction

The use of the electronic
temperature regulation ATR-6 is
required for this function.
In the following, a type of function
is described where the highest
possible energy efficiency is
enabled by the fan-assisted air
heater with the help of the control
PCB and electronic temperature
regulation.
In order to start the process of
environmental correction, the
parameter C1 = 1 must be set.
The goal of the room correction
function is to begin heating up the
area quickly and then to maintain
a constant room temperature. In
doing so, the formation of layers
in the room's air can be reduced
in addition to the reduction of the
fuel requirement, in particular.
The two reference values for the
correction are the temperature
measured by sensor NTC2 (in the
electronic temperature regulation)
and the temperature detected by
the sensor NTC1 (on the unit).
In order to activate the sensor
NTC2, change parameter A12 and
set to 1.
If the room temperature
approaches the set value for
the set-point, the modulation
temperature is changed linearly on
the basis of the two parameters
A16 and A24.

This enables the operation of
the unit at the beginning of the
heat requirement and the quick
realisation of the pre-adjusted
value for the target value of the
room. Then the heat output is
reduced, whereby the efficiency of
the unit is increased and the room
is heated with less hot air.
In this way it is possible to reduce
the formation of layers and at the
same time reduce heat loss in the
room's air.
The units are delivered with the
following factory settings.
Modulation temperature:
„REG SAN“

24°C

Neutral correction range:
A24

2°C

Correction coefficient:
A16

2.5

The parameter A24 determines
the range within which the
room temperature is corrected.
The parameter A16 offers the
possibility to increase the efficiency
of the temperature reduction
to the set-point "REG SAN", as
shown in the graph. With the
standard settings, the modulation
temperature, when reaching the
room temperature, corresponds to:

„REG SAN“ =
24°C-(2°Cx2.5) = 19°C
The correction is independent of
the adjusted room temperature.
The progression of the room
temperatures [ST2] in relationship
to the installation height of the
units "REG SAN" during the initial
heating phase is represented on
the graph.
Set parameter C1= 0 for
deactivation of the correction.
With deactivation of the
correction, the value "REG SAN"
must be correctly regulated in
order to avoid the following
conditions:

- "REG SAN" set too high:

Strong formation of layers with
high heat loss in the ceiling area
and subsequently increased
energy requirement.

- "REG SAN" set too low:

Time to reach the desired room
temperature is too long.

With deactivated correction, set
"REG SAN" so that the value of
the difference in meters between
room and modulation sensors
multiplied by 0.4/0.5 °C is greater
than ST2.
To change the modulation value
"REG SAN" on the electronic
temperature regulation and to
change all described values,
