Features

• Heating actuator with integrated room temperature controller for controlling electrothermal actuators for heating and cooling systems.

Valve outlets

• 6 independent electronic valve outputs.
• Valve output 1 can be used as a template for other valve outputs.
• Message of the largest manipulated variable of the actuator can be parameterized.
• Actuators can be controlled with a nominal voltage of 24 V or 230 V.
• Valve control (de-energized open / closed) configurable for each output.
• Actuating variable input: “switching – 1 bit” and “continuous – 1 byte”.
• Valve control: “switching – 1 bit”, “continuous – 1 byte PWM” or “continuous – 1 byte command value limit value”.
• Status feedback configurable.
• Failure message of the valve operating voltage configurable.
• Overload and short-circuit notification can be set separately for each valve output.
• Heat demand and pump control. Anti-seize protection prevents the pump from seizing.
• Summer or winter mode can be selected via an object.
• Each valve output can be locked in a forced position. Different control variable values can be configured for summer and winter operation.
• Cyclic monitoring of the manipulated variable of each output.
• Automatic valve flushing.
• Operating hours counter configurable for each output.
• Service operation for the maintenance or installation of valve drives.
• Manual operation of the outputs independent of the KNX.
• Reactions to bus voltage failure and return and after ETS programming can be set for each valve output.
• Various actively transmitting status messages can be sent after bus voltage return or after an ETS programming
• Delay process globally.

Room temperature controller

• 12 independent room temperature controllers.
• Room temperature controller 1 can be used as a template for other room temperature controllers.
• Operating modes: comfort, standby, night and frost/heat protection.
• Each operating mode can be assigned its own set temperature values.
• Target temperature specification: relative (derivation from basic target value) or absolute (independent target temperatures for each operating mode).
• Presence detection by presence button or presence detector.
• Switching of the operating modes according to the KNX specification.
• Status feedback configurable.
• Frost/heat protection switching through window status or temperature drop detection.
• Operating modes: “Heating”, “Cooling”, “Heating and cooling” each with or without an additional stage.
• Different control types can be configured for each heating or cooling stage: PI control (continuous or switching PWM) or 2-point control (switching).
• Various types of heatin
