4 Product description

The single room temperature controller RoCon UFH is used to control the temperature in rooms with underfloor heating system (heating and cooling). The controller compares the actual temperature and the reference temperature and controls the volume 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 actuators 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 programmable switching channels for temperature reduction. A total of 9 programmable memory 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 versions wired and wireless(1) can also be operated in mixed mode.

(1)The wireless system is only available in certain sales areas.
