In order to optimally plan the Vitramo heating system, it is not only designed according to DIN EN 12831, but also adapted to the special conditions of the building. Already during the planning phase, a building is divided into rooms, demand zones and heating areas depending on its size and use. A demand zone represents a space/space defined by its specific type of use and conditions such as cooling, ventilation, humidity, etc. Every room needs a room thermostat to regulate the air temperature. Wire-guided room thermostats as room temperature controllers are wired directly to a heating element. Due to the structural conditions, these devices are often used in new buildings or as part of a renovation. If the installed power exceeds the specified switching capacity of the respective room thermostat, then the heating elements must be switched via additional load relays type LS-E. In any case, the life of the room thermostat will be extended if a load relay does the work.
