Glossary
Set-back temperature
The set-back temperature is the reduced interior
temperature maintained by your heating system outside
of the programmed time window.
Operation level for operator
Used to display and set/change the basic parameters.
The setting/changing of parameters can be carried out
by the user without any special previous knowledge and
during normal operation. The heating system can
continuously adapt to the requirements of the operator
by making the corresponding basic parameter settings.
Operation level for expert technician
Used to display and set/change specific parameters. This
operation level is reserved for the expert technician and
is therefore password protected.
Operating mode
The operating modes "Auto" (automatic), "Manual“ and
"OFF" exist. You can use the operating modes to specify
how you wish your room heating or water heating to be
controlled (see operating instructions, Section 4.3.2,
Table 4.2).
Heating circuit (HC1)
HC1 indicates heating circuit 1. This refers to the heating
of your heating system. You can use a special
designation instead of HC1 (see operating instructions
Section 4.7.5).
Heating flow temperature
Your appliance heats water which is pumped through
your heating system. The temperature of this hot water
as it leaves the appliance is referred to as the flow
temperature.
Interior temperature
The interior temperature, also referred to as room
temperature, is the actual current temperature in your
apartment.
Parameter
Parameters are the properties of your heating system.
You can influence these properties by altering the value
of a parameter, such as, e.g. reducing the value of the
parameter "Night set back temp" from 15 °C to 12 °C.
Room target temperature
The room target temperature is the temperature that
should prevail in your apartment and is specified at the
controller. Your appliance supplies heat until the interior
temperature matches the room target temperature.
When entering time programmes the room target
temperature is also referred to as the comfort
temperature.
Set values
The target values are your desired values that you can
specify via the controller; e.g. the room target
temperature or the target temperature for hot water
generation.
Summer/Winter changeover
Under the menu point "Mode selection" in screen 1
"Basic data" you can determine whether the changeover
from summer to winter and vice-versa should take place
automatically (Selection: Auto).
The factory setting (as-supplied condition) is for
automatic changeover not to take place (Selection: Off).
Flow temperature
See heating flow temperature.
Water heating
The water in the hot water cylinder is heated to the
selected target temperature by the appliance. If the
temperature in the hot water cylinder falls by a specific
amount the water is heated again until it reaches the
target temperature. Time windows for water heating
can be programmed.
Time window
Three time windows can be programmed per day for the
heating, water heating and circulation pump
(see operating instructions Section 4.7.1).
A target value is allocated to each time window
programmed for the heating.
In the case of water heating the hot water target
temperature applies for all time windows (Screen 10
"Hot water parameters").
In the case of the circulation pump the time windows
determine the operating times.
In automatic mode the system is controlled is in
accordance with the specified values in the time
windows.
Circulation pump
Depending on the length of the pipe, there may be a
brief delay before hot water flows when the hot water
cock is opened. A circulation pump circulates hot water
via your hot water pipe. This means that hot water is
available instantly when the water cock is opened. Time
windows can be programmed for the circulation pump.
