6-fold Heating actuator with controller

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 heating and cooling can be set.
• Adjustable control parameters for PI controller (proportional range, reset time) and 2-point controller (hysteresis).
• Automatic or object-oriented switching between "heating" and "cooling".
• Blocking of the manipulated variable outputs via objects possible.
• Room temperature measurement via up to two external KNX temperature sensors. Measured value formation of the external sensors can be parameterized or cyclical monitoring.
• The actual and target temperatures can be output to the bus (also cyclically) after a parameterizable deviation.
• Separate or common variable output in heating and cooling mode (4-pipe or 2-pipe system).
• Automatic sending and cycle time for command value output can be parameterized.
• Actuating variable limitation possible.
• Floor temperature limitation possible in heating and cooling mode.
• Target temperature limitation possible in cooling mode.
• Target temperature increase possible in heating mode.
• Boost function for quick heating up or cooling down.
• Scenes: Up to 64 internal scenes can be configured for each controller. Including scene memory function and expanded scene recall (toggling of scenes).

Logic functions

• The device has 8 internal logic functions.
• Logic gates (AND, OR, exclusive AND, exclusive OR, each with up to 4 inputs).
• 1-bit to 1-byte converter with input filter, blocking object and specification of the output values.
• Blocking element with filter and time functions and blocking object.
• Comparator for values ​​with 9 different input data formats and many comparison operations.
• Limit switch with hysteresis with upper and lower threshold for 9 different input data formats.
• Including specification of the 1-bit output values.
• The logic functions have their own KNX communication objects and can process telegrams from the actuator or other bus devices.
