2 Overview
2.1 Overview Devices
The manual refers to the following glass room temperature controller (order number printed in bold
letters):
SCN-RT1GW.01 Glass Room temperature controller, white
oController type: Two-position, PI, PWM
oconfigurable LCD display with automatic brightness adjustment and adjustable alarm
messages
oventilation control controllable by bit, byte or binary coded
o2 keys configurable
SCN-RT1GS.01 Glass Room temperature controller, black
osame functions as before
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.

2.5 Functions
The functions of the glass room temperature controller are divided into the areas of LCD display,
temperature control, ventilation control and configuration of the keys. In each area, the following
settings can be made:
LCD Display
The presentation and the brightness of the display can be set here. Furthermore the
language of the Display and an inverting of the colors can be set here.
Temperature Controller
The temperature controller is again divided into the following sub-menus:
oTemperature measurement
In this menu, settings for temperature measurements, such as min / max values and
sensor configurations can be parameterized.
oAlarm/Messages
Alarms / messages, which show falling below or exceeding certain temperatures, can be
set here. Also messages, which are shown at the display, can be set here.
oController general
The desired function (Heating and/or Cooling) are set in this menu. Furthermore the
setpoints and operating modes can be set here.
oController settings
If one type of controller is set, the behavior of the manipulated variable can be set here.
The setting options depend on the used controller.
Ventilation Control
The ventilation control allows the control of fans and can be controlled as well manually as
by the current value of the output value or by the difference between setpoint and current
value.
Key function of button C/D
The key function can be set as well grouped as separately. As well switching function as
shutter and dimming functions can be used.

2.6. Settings at the ETS-Software
Selection at the product database:
Manufacturer: MDT Technologies
Product family: Control
Product type: Any
Medium Type: Twisted Pair (TP)
Product name: SCN-RT1GW.01
Order number: SCN-RT1GW.01
2.7. Starting up
After wiring the allocation of the physical address and the parameterization of every channel follow:
(1) Connect the interface with the bus, e.g. MDT USB interface
(2) set bus power up
(3) Press the programming button at the device(red programming LED lights)
(4) Loading of the physical address out of the ETS-Software by using the interface(red LED goes
out, as well this process was completed successful)
(5) Loading of the application, with requested parameterization
(6) If the device is enabled you can test the requested functions(also possible by using the ETS-
Software)
