RT
The regulating unit consists of a switchgear. In it, a RNET_P control unit can be placed. Further, the regulator mostly contains semi-conductor switching elements for switching the individual heating components (channels).
A long lifespan and nioselessness are big advantages of semi-conductor switching. The RT unit is produced for 4 to 32 channels in three sizes. There is also space for clamps and circuit breakers of each channel. Apart from the supply cable, cables of all analogue floor and spatial sensors and supply cables for all heaters are lead into the regulating unit. Digital spatial sensors are connected by using a three-conductor communication bus bar. Beside the simpler cabling, digital sensors provide temperature display and the eventual correction of settings in the given space.
RTR
If placing the RT unit onto a wall is inconvenient, it can be embedded with an RTR frame. This frame primarily provides good ventilation for the semi-conductor switching elements.
RNET_P
The control unit represents the brain of the system. It is most often placed into the RT switchgear, but thanks to the three-wire communication bus bar, it can also be moved to a more accessible spot. All system parametres can be set on this unit using the display and keyboard.
RPC
The operating PC software enables a more comfortable control of the system. Groups of rooms and corresponding time programs can be established on a computer, based on the use regime. Beside the programming, the software offers on-line monitoring of the room temperatures, counting of operation hours, graphic illustration of the temperature development during the past period, etc. The RNET_P control unit is most often connected to a PC by a USB convertor. Using a WiFi or GSM module, remote control is possible. In extensive objects (e.g. hotels), where the capacity of one RT system is insufficient, multiple systems can be installed and up to 512 channels can be operated through one RPC software.

Analogue floor RT_P and spatial RT_L sensors are available, or the more comfortable digital sensors with the RT_NET_DN option of space temperature display and its correction. Spatial sensors can be supplied in various designs and colours of the ABB, Unica, etc. completion lines. They can be combined in multiple frames, e.g. with switches.
HJ
The controller of the main circuit breaker value controls the current in every phase and enables to switch the heating off, so that the maximal value of the circuit breaker of the object is not exceeded. It thus enables to lower the size of the main circuit breaker while maintaining the other functions of the wiring of the object.
If floor heating is a part of a complete electrical heating of an object, we recommend to regulate with a complex control system, e.g. BMR RT. This system provides comfortable configuration and operation of electrical heating while reaching a maximal efficiency and reliability of the system.
