Room correction
For this function, use of the
temperature control ATR.6 is
necessary.
A type of function is described
in the following that enables
maximum energy efficiency to
be achieved by the hot air heater
assisted by the control electronics
and temperature control.
In order to activate the ambient
correction function, the parameter
[C1]
param k 11 must be set to 1.
The purpose of the room
correction function is to ensure
rapid heating at the beginning and
subsequently maintain the room
temperature at a constant level.
In this way, not only can layer
formation in the room air be
reduced, but also the fuel demand
reduced in particular.
The two correction reference
values are the temperature
measured by the sensor NTC2
(in the temperature control) and
the circulation air temperature
measured by the sensor NTC1 (at
the unit).
To activate the function, set the
parameter
param k 17 to 1.
When the room temperature
approaches the setpoint value,
the modulation temperature is
changed linearly based on the two
parameters A16 and A24.
This makes it possible to operate
the unit on heat demand
at maximum output and to
quickly reach the preset room
temperature.
The heat output is subsequently
reduced which increases the
efficiency of the unit and the room
is heated with less hot air.
This enables the layer formation in
the room air and simultaneously
the heat loss to be reduced.
The units are supplied with the
following factory settings:
Modulation temperature:
„REG SAN“
22°C
Neutral correction range:
A24
2°C
Correction coefficient:
A16
2
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 setpoint “REG SAN” as
shown on the graph. At the
standard setting, the modulation
temperature on reaching the room
temperature corresponds to:
„REG SAN“ =
24°C-(2°C x 2.5) = 19°C
The correction is independent of
the set room temperature.
The graph shows the room
temperatures [ST2] in relation
to the installation height of the
units „REG SAN“ during the initial
heating phase.
To deactivate the correction, set
the parameter [C1]
param k 11 to
0.
When deactivating the correction,
the value “REG SAN” must be
correctly regulated in order to
avoid the following conditions:
- „REG SAN“ adjusted too high:
Strong layer formation with
high heat loss in roof area and
increased energy demand as a
consequence.
- „REG SAN“ adjusted too low:
Time to reach the required room
temperature too long.
With correction deactivated, adjust
“REG SAN” so that the value is
higher than ST2 by the difference
in metres between the room and
modulation sensor multiplied by
0.4/0.5°C.
To change the modulation value
“REG SAN” on the temperature
control and to change all specified
values, see further back in the
manual.
