This system is gradually substituted by more modern and enhanced system TECOMAT FOXTROT and we do not recommend to use it in the new projects. More information you can find in category dedicated to PLC Tecomat Foxtrot. 

Tecoreg of series TR300 is a controller designed for medium to larger applications on the field of heating control, air-conditioning, boiler rooms, interchange stations, etc. in which no control panel or space separation of the control panel are required. A great number of communication possibilities predetermines the application of the controller also in extensive applications in co-action with other Tecoreg and PLC Tecomat controllers. The controller is freely programmable and thus usable for both in series repeated applications and of special customer orders.
