2.2 Usage & Areas of Applications
The Glass Room temperature controller combines the complex temperature control with the simple
operation on the glass LCD display. For this purpose, 4 buttons and a large LCD display are available.
Two of the four buttons are available for free parameterization by the user; the other two buttons
are used to operate with the display. In addition, the screen can show up to 4 alarms that are
triggered via 1-bit objects, as well as a 14-byte text message.
With the control various control schemes can be realized. Applications range reaches from the room
temperature controlling of a room with heating and / or air conditioning as well as in heating or
cooling systems.
The application program of the room temperature controller allows you to use your device for
"heating.", "cooling." or "heating and cooling-systems". Depending on which function is selected, the
ETS displays various parameters and communication objects. All control functions can be used for
"heating" and / or "cooling" with a "2-point control", a "PWM control" or a "continuous PI control".
In addition, an additional stage for heating control can be used. For a better temperature recording
in larger rooms, a temperature value can be received by a further measuring sensor via the bus. The
received measurement value is incorporated in accordance with a set of weighting in the room
temperature control. The temperature controller works with setpoints, which serve as reference
points for the control. Various setpoints for different operating modes can be parameterized. In
addition, these references can be shifted via communication objects. In addition, the glass room
temperature controller has an integrated ventilation control, which can work with the control value
of the temperature controller or can be controlled manual.
