 Output signal inversion as an option (DC 0...10 V  DC 10...0 V)

 2 multifunctional inputs for keycard contact, external sensor, etc

 Operating modes: Comfort, Economy and Protection

 Control depending on the room or the return air temperature

 Supply fan optimization: Input DC 0...10 V for damper position feedback

 Automatic or manual heating / cooling changeover

 Minimum and maximum limitation of room temperature setpoint

 Minimum and maximum limitation of air flow signal

 Adjustable commissioning and control parameters

 Commissioning with Synco ACS700, ETS3 Professional or via local HMI

 Integration into Synco

 Integration into DESIGO via group addressing (ETS3) or via individual

addressing

 Integration into third-party system via group addressing (ETS3)

 Operating voltage AC 24 V

Use The RDG400KN room thermostat is designed for the following types of system: VAV systems via ON/OFF or modulating control outputs:  Single-duct system  Single-duct system with electric heater  Single-duct system and radiator / floor heating  Single-duct system with heating / cooling coil The room thermostat is delivered with a fixed set of applications.
PAGE 3
Applications The thermostat supports the following applications, which can be configured using the DIP switches at the rear of the unit or a commissioning tool. DIP switches 1...3 need to be set to OFF (remote configuration, factory setting) to select an application via commissioning tool.

Mounting and installation Do not mount on a wall in niches or bookshelves, behind curtains, above or near heat sources, or exposed to direct solar radiation. Mount about 1.5 m above the floor. Mounting  Mount the room thermostat on a clean, dry indoor place without direct airflow from a heating / cooling device, and not exposed to drips or splash water. Wiring See the mounting instructions M3192 enclosed with the thermostat.  Comply with local regulations to wire, fuse and earth the thermostat.

After power is applied, the thermostat resets and all LCD segments flash, indicating that the reset was correct. After the reset, which takes about 3 seconds, the thermostat is ready for commissioning by qualified HVAC staff. If all DIP switches are OFF, the display reads "NO APPL" to indicate that application commissioning via a tool is required.

Programming mode The programming mode helps identify the thermostat in the KNX network during commissioning. Press the left and right buttons simultaneously for 6 sec to activate programming mode, which is indicated on the display with "PrOg". Programming mode remains active until the identification of the thermostat is complete. Assign KNX group addresses Use ETS3 Professional to assign the KNX group addresses of the RDG communication objects,.
