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.
