The following example shows a floor plan with an integrated HVAC + blinds and lighting
RX application. Situation:
– The North and South sides of the floor each consist of 6 room modules with one RX
controller and the controller's peripherals. The corresponding TEC rooms are defined
according to the room modules (master/slave relations where needed).
– The offices and production are located in different HVAC zones, but have the same
occupancy hours.
– The warehouse is kept at a constant temperature. The blinds normally are down.
– The North and South side of the building each have their own energy distribution for
heating and cooling energy.

Below are the groups that are necessary to achieve the intended functionality (for
reasons of clarity, the above illustration does not contain all of them):
Groups Designation / explanation
HVAC – TCG 1: Production (HVAC group North).
– TCG 2: Offices (HVAC group South).
The warehouse is not a group, as it is an individual room at constant temp.
Blinds – AOu: Production.
– AOv: Warehouse.
– AOw: Front side North.
– Further groups are: Building front South, building front East, entire floor.
Note: In the corner office TCR4, the blinds on the East side of the building
rather than being connected to the South group are connected to the East
group to ensure that the shading function works properly.
Lighting – AOx: Production.
– AOy: Warehouse.
– Further groups are: Offices, entire floor.
TED By allocating the associated RX controllers, the following four groups, for
example, can be formed for energy demand:
– Heating demand for production, cooling demand for production.
– Heating demand for offices, cooling demand for offices.
