1.82>1.90 In the conguration level CO1, the 'Four-point characteristic' function can also be con-
gured for systems Anl 3.x. See CO1>F11.
The demand for the maximum ow set point issued by a 0 to 10V signal can be made
with an adjustable boost. See CO1>F18-1.
The controller can be connected to an optional Modbus gateway.
1.90>1.95 The priority operation (reverse control or set-back operation) can be set independently
from the time and temperature course of the plant (see sections7.8.1 and 7.8.2).
The setting CO1>F20-1 allows an external demand for heat to be made when insuf-
cient heat is supplied (see section8.18).
1.95>2.00 The limit switch for creep feed rate limitation can also be connected to input RüF1. In
previous versions, it could only be connected to terminals 04/12 (see section8.12).
2.00>2.12 New hydraulic system Anl 11.6 (see page 50).
New cooling control function (see section 6.11)
The cooling control function causes a reversal of the operating direction and a mini-
mum limitation of the return ow temperature in HC1/HC2.
The demand processing using a 0 to 10V signal can be applied variably to the 0 to
130°C transmission range (see section8.11).
2.12>2.13 The priority operation (reverse control and set-back operation) can be activated for
system Anl 4.5 either for one heating circuit (HC1 or HC2) or for both heating circuits
(HC1 and HC2). See section 7.8.
New function to control the speed of the charging pump based on the charging prog-
ress (see section7.7).
2.13>2.14 Error messages can be issued over binary inputs BI1 and/or BI2 when the binary input
is a made or break contact (see section13.1).
2.14>2.20 New hydraulic systems Anl 16.x (buffer tank systems). See page52.
The drying of jointless oors is not canceled due to a deviation in the ow temperature
(see section6.3).
2.20>2.24 Internal revisions
2.24>2.26 Function to receive outdoor temperature as 0 to 10V signal extended (CO5>F23)
Outdoor temperatures can be received or sent using a 0 to 10V signal.
2.26>2.28 New system Anl 11.5 (see page49)
2.28>2.30 It is possible to connect PTC and Ni1000 sensors (Pt1000 sensors only possible below
this rmware version)

1 Safety instructions
For your own safety, follow these instructions concerning the mounting, start up and opera-
tion of the controller:
−The device is to be mounted, started up or operated only by trained and experienced
personnel familiar with the product.
−For electrical installation, you are required to observe the relevant electrotechnical regu-
lations of the country of use as well as the regulations of the local power suppliers. Make
sure all electrical connections are installed by trained and experienced personnel! Before
performing any such work on the controller, disconnect it from the power supply.
−The device is designed for use in low voltage installations. For wiring and maintenance,
you are required to observe the relevant regulations concerning device safety and elec-
tromagnetic compatibility.
To avoid damage to any equipment, the following also applies:
−Proper shipping and storage are assumed.
−Before start-up, wait until the controller has reached the ambient temperature.
1.1 Disposal
Waste electrical and electronic equipment may still contain valuable substances. They may
also, however, contain harmful substances which were necessary for them to function. For
this reason, do not dispose of this kind of equipment together with your household waste. Se-
lect a suitable disposal method. Instead, dispose of your waste equipment by handing it over
to a designated collection point for the recycling of waste electrical and electronic equipment.

2.2 Operating modes
Day mode (rated operation): regardless of the programmed times-of-use and summer mode,
the set points relevant for rated operation are used by the controller. Icon:
Night mode (reduced operation): Regardless of the programmed times-of-use, the set points
relevant for reduced operation are used by the controller. Icon:
Control operation deactivated: regardless of the programmed times-of-use, control opera-
tion remains deactivated. The frost protection is activated, if need be. Icon:
Automatic mode: during the programmed times-of-use, the controller works in day mode
(rated operation). Outside these times-of-use, the controller is in night mode (reduced opera-
tion), provided control operation has not been deactivated due to the outdoor temperature.
The controller switches automatically between both operating modes. Icon:
Manual mode: valves and pumps can be controlled manually (see section4). Icon:

2.4 Activate the information level
In the normal switch position (information level), the time, date, public holidays and vaca-
tion periods as well as the temperatures of connected sensors and their set points can be dis-
played.
The data can also be read in the operating level (manual mode). In this case, select and
conrm InFo on the display and proceed as described below.
Proceed as follows:
1. Select value [q].
Depending on how the controller is congured, the current values of the following data
points appear one after the other on the display:
