Setback Types; Information On The Heating Curve Main Menu - Bosch Control 8313 Service Instructions For Contractors

Remote Control
The operating modes are restricted when using a TR25 remote control in
a heating circuit. The temperatures are specified by the remote control.
The temperature in Automatic heating mode is specified by the rotary
selector. The temperature in Automatic setback mode is specified by
the Delta-T setting in the remote control. The Manual heating mode and
Manual setback mode are specified by the keys on the remote control.
The temperatures are identical to those in the automatic mode. The
preset values in the service menu are overwritten by the values set in the
remote control.

12.2.2 Setback types

As different parameters can be entered for every heating circuit, the
setback types for every heating circuit must also be entered separately.
The settings of the setback types depend on the heating systems and the
adjustable parameters in these systems.
You can switch between the Automatic heating mode (day) and
Automatic setback mode (night) operating modes automatically via the
time program, or manually via an external contact at the FM-MM function
module.
The following settings must be made for the setback modes that are
known to date:
▶ Go to Service level > Heating circuit > Heating curve to select the
Automatic setback mode operating mode (night).
▶ Make the settings for the relevant setback type.
Reduced
The control is set to a lower set room temperature value (reduced
temperature) and continuously activates the heating circuit pump. The
control system operates by means of parallel downwards displacement
of an outside-temperature dependent heating curve.
Settings for the parameters:
Standby mode
Heating Limit
(Summer from /
Outdoor Setback)
Outside temperature threshold
This operating mode is a combination of the Standby mode and
Automatic setback mode. The heat source operates in Automatic
setback mode below an adjustable outside temperature and in Standby
mode above an adjustable outside temperature.
Settings for the parameters:

Standby mode (shutdown)
The heating circuit is always switched off in setback mode. In this
operating mode, the heating circuit pump is completely switched off but
the frost protection remains effective.

Room temperature threshold
The heating system remains in Standby mode as long as the room
temperature does not fall below a set minimum value (reduced
temperature). Otherwise the control switches to Automatic setback
mode. This function can only be activated if a remote control has been
connected in a reference room.

Information on the Heating curve main menu

The heating curve set refers to the heating system selected under the
menu item Heating circuit data > Basic setting. The settings can be
made in a table or a graphic representation.
The heating curve can be set for each heating circuit separately.
The heating curve depends on the preset parameters of the heating
circuit. It is limited by the Maximum flow temperature and Minimum
flow temperature parameters.
List selection
You can open the list of modifiable parameters by showing/hiding it in
the list selection.
Graphic representation
The graphic representation is only available for Heating system
Radiator/Underfloor Heating.
You can modify the heating curve in the graphic representation by
changing (tapping and moving) the reference points.
If you tap on a reference point, a room temperature or a rhombus,
the temperature appears in the display. You can change the room
temperature by tapping and moving the Room temperature setpoint [5].
The change is also saved in the time program.
The heating curve is displayed for the operating mode that is set [5]. You
can change over the operating mode by tapping the corresponding field
for the operating mode.
