2 Information on safety
2.1 Safety messages and hazard categories
These operating instructions contain safety messages to alert you to potential haz-
ards and risks. In addition to the instructions provided in these operating instructions,
you must comply with all directives, standards and safety regulations applicable at the
installation site of the product. Verify that you are familiar with all directives, standards
and safety regulations and ensure compliance with them prior to using the product.
Safety messages in these operating instructions are highlighted with warning symbols
and warning words. Depending on the severity of a hazard, the safety messages are
classified according to different hazard categories.
In addition, the following symbols are used in these operating instructions:
DANGER
DANGER indicates a hazardous situation, which, if not avoided, will result in
death or serious injury.
NOTICE
NOTICE indicates a hazardous situation, which, if not avoided, can result in
equipment damage.
This is the general safety alert symbol. It alerts to injury hazards or
equipment damage. Comply with all safety instructions in conjunc-
tion with this symbol to help avoid possible death, injury or equip-
ment damage.
This symbol alerts to hazardous electrical voltage. If this symbol is
used in a safety message, there is a hazard of electric shock.

2.2 Intended use
This product may only be used to control the room temperature (heat/cool) of individ-
ual rooms with underfloor heating system.
The controller modules may only be used to control the thermostatic actuators via the
signals of the associated room controllers and the base module.
Any use other than the application explicitly permitted in these operating instructions
is not permitted and causes hazards.
Verify that the product is suitable for the application planned by you prior to using the
product. In doing so, take into account at least the following:
• All directives, standards and safety regulations applicable at the installation site of
the product
• All conditions and data specified for the product
• The conditions of the planned application
In addition, perform a risk assessment in view of the planned application, according
to an approved risk assessment method, and implement the appropriate safety meas-
ures, based on the results of the risk assessment. Take into account the conse-
quences of installing or integrating the product into a system or a plant.
When using the product, perform all work and all other activities in conjunction with
the product in compliance with the conditions specified in the operating instructions
and on the nameplate, as well as with all directives, standards and safety regulations
applicable at the installation site of the product.
2.3 Predictable incorrect application
The product must never be used in the following cases and for the following purposes:
• Hazardous area (EX)
- If the product is operated in hazardous areas, sparks may cause deflagrations,
fires or explosions
• In conjunction with products which are used for health-saving or life-saving pur-
poses or whose operation may incur hazards to humans, animals or property

4 Product description
The single room temperature controller RoCon UFH is used to control the tempera-
ture in rooms with underfloor heating system (heating and cooling). The controller
compares the actual temperature and the reference temperature and controls the vol-
ume flow of the heating water via the corresponding thermostatic actuators.
The room controllers measure the actual temperature in the corresponding rooms.
The reference temperature is adjusted via the rotary knob of the corresponding room
controllers.
The controller modules with 2 or 6 independent control circuits control the respective
thermostatic actuators via the signals of the room controllers and the base module.
Th base module supplies the room controllers with 5 V DC and the thermostatic actu-
ators with 230 V AC. The single room temperature controller RoCon UFH can be
switched between heating and cooling via the base module. The control circuit pumps
can be controlled via the base module.
The optional timer module features a hundred year calendar. The display shows the
date, time and day of the week. The timer module features 2 independently program-
mable switching channels for temperature reduction. A total of 9 programmable mem-
ory blocks are available. The additional pump running time can be set via the timer
module. The timer module has a valve and pump protection function.
The single room temperature controller consists of a base module, at least one room
controller and at least one controller module. Multiple controller modules with 2 or 6
control circuits can be adapted.
The single room temperature controller RoCon UFH is available in 2 versions(1):
• Room controller and controller modules are interconnected by a cable.
• Room controllers and controller module are connected via EnOcean®wireless(1).
The single room temperature controller RoCon UFH is a modular system. The ver-
sions wired and wireless(1) can also be operated in mixed mode.
(1) The wireless system is only available in certain sales areas.
