Operation

1.5 Selecting the operating mode (presence button)
Press key repeatedly to cycle through the following operating modes:.
Temporary set point settings (see section 1.6) are reset when the operating mode is changed.
Automatic mode
( during time-of-use, no icon appears outside of time-of-use; 6…5…6)
Depending on the programmed time schedule, the controller regulates the room tem-
perature to the
Set point for time-of-use during the time-of-use and to the Set point
for outside of time-of-use
outside of the time-of-use.
Time-of-use (;55555…)
The controller regulates the room temperature to the
Set point for time-of-use regard-
less of the programmed time schedule.
Outside of time-of-use (66666…)

1.6 Changing temperature set points temporarily
During the controller operation, the current set point and the actual temperature appear on the
display.
Use the arrow keys to temporarily change the current set point.
The new temporary set point applies until the next time-of-use starts or until the operating mode
is changed, however, eight hours at the maximum.
The following maximum set point shifts apply:
4
Set point for time-of-use : ±3 °C
4
Set point for outside of time-of-use: +8 °C

2.3 Calibrating the room sensor
If the temperature displayed on the room controller (current temperature on the bottom right of
the display) does not match the actual room temperature, the measured temperature of the
room sensor can be changed and reset. On calibration, the currently displayed sensor temper-
ature needs to be changed to match the directly measured room temperature (reference temper-
ature).
Note!
An incorrectly performed calibration leads to the wrong room temperature measurements and
results in incorrect control performance. Use a thermometer with a high degree of accuracy on
measuring the reference temperature.
How to proceed:
Open cover.
Select
Communication parameter level.
Enter the key number.
The parameter level is opened.
The device address appears on the display.
The Baud rate appears on the display.
The transmit/receive test appears on the display.

3 Functions
3.1 Heating functions
3.1.1 Window contact
The window contact function depends on the state of binary input BE1:
4BE1 = 0: The heating valve is closed.
The heating valve is opened for five minutes every 20 minutes
4BE1 = 1: Control according to the current operating mode.
3.1.2 Optimization
The controller determines the Advance heating time and Cooling down time depending on the
building characteristics.
The
Advance heating time is the time required to achieve the room temperature Set point for
time-of-use
already when the time-of-use starts. In optimization mode, heating does not start
when the time-of-use starts, but at an earlier point in time instead.
The
Cooling down time is the time required to achieve the room temperature Set point for out-
side of time-of-use
already when the time-of-use ends. In optimization mode, heating does not
finish when the outside of time-of-use starts, but at an earlier point in time instead.
Note!
Advance heating time and Cooling down time are restricted by the Maximum advance heating
time
and Maximum cooling down time parameters respectively.

3.2 Cooling functions
The cooling valve regulates the temperature to the current set point during the time-of-use.
The following applies for outside of time-of-use:
When F04 - 0: No cooling
When F04 - 1: The temperature is regulated to a raised set point. The setback calculated
from the set point for outside of time-of-use during heating is interpreted
as an increase.

3.2.1 Window contact
The Window contact function depends on the state of binary input BE1:
4BE1 = 0: The cooling valve is closed.
4BE1 = 1: Control according to the current operating mode.
3.2.2 Dew point monitoring
The dew point monitoring uses the binary input BE2:

3.6 Switching outputs

are not processed.
Parameter WE Parameter level / Range of values
Min. control signal 5 % PA Control / 1 to 100 %
Three-point stepping output (heating only)
The control loop functions with a PI control algorithm. The heating valve reacts to pulses which
the controller issues when a system deviation exists. In particular, the length of the first pulse de-
pends on the size of the system deviation and the selected
Gain K
P
(the pulse length increases
as KPrises). Pulse length and interval time change continuously until the system deviation is
eliminated. The interval between pulses is influenced considerably by the
Reset time T
N
(the in-
terval increases as TNrises). The
Valve transit time T
Y
indicates how long the valve needs to
move through the range from 0 to 100 %.

A control signal is issued when the temperature exceeds or falls below the set point, depending
on the controlled variable. If the control signal exceeds the
Min. Control signal , the on-off ther-
mostat is switched on or off.
