MTN6730-0002 Schneider SpaceLogic KNX Valve Drive Controller Description：
For actuation of electrothermal valve drives for heating or cooling ceilings. The valve drive controller has 6 electronic outputs. Up to 4 valve drives (230 V AC) or 2 valve drives (24 V AC) can be connected to each output. Both de-energized closed and de-energized opened valve drives can be connected.
In addition, the valve drive controller contains 6 integrated room temperature controllers (RTC) which operate independently of each other. The correcting variable outputs of these RTCs can be linked internally with the valve outputs, so that temperature control and valve actuation can be performed by a single bus device only, if required. In this case, no external room temperature controller (e.g. push-button with RTC) is required.
As the valve outputs can be controlled individually, an external RTC can also be used at any time.
The integrated room temperature controllers can send the correcting variable telegram to the bus and thus control other heating actuators or fan coil actuators.
The outputs are either switch activated (1 bit) or PWM signal (1 byte) activated. Each output is overload-protected and short-circuit-protected.
All outputs can be operated manually using push-button operation. Building site operation is possible.
For installation on DIN rails TH35 according to EN 60715. The bus is connected using a bus connecting terminal.
MTN6730-0002 Schneider SpaceLogic KNX Valve Drive Controller software functions – valve:
valve activation (deenergised opened / closed) can be configured for each output, actuator evaluation as “Switching, 1-bit”, “Constant, 1-byte” or “Constant 1-byte with actuator limiting value and hysteresis”, status feedback, collective feedback of all valve states via 4-byte telegram, combined valve status via 1 byte, failure signal of the valve operating voltage can be configured, overload and short-circuit signal for each valve output, automatic valve rinsing, summer/winter switch-over for valve outputs, valve command value limit, forced position configurable, activation of service mode with defined valve position
MTN6730-0002 Schneider SpaceLogic KNX Valve Drive Controller software functions – RTC:
operating modes “Heating”, “Cooling”, “Heating and Cooling” each with or without additional level, configuration of the temperature setpoints as relative (derived from basic setpoint) or absolute (independent setpoint temperatures for each operating mode), PI control, PWM or switching 2-point feedback control, automatic or object-oriented switch-over between “Heating” and “Cooling”, temporary or permanent setpoint shift through communication objects possible (e.g. via a controller extension), configurable step width of the setpoint shift (0.1 K / 0.5 K), calibration of the temperature values possible and measured value formation of the external sensors can be configured, separate or shared command value output in heating and cooling mode, floor temperature limit in heating mode, setpoint temperature limit in cooling mode, operating hours counter to record the switch-on times of the valve outputs
