heat.act. 6-g cont. OneKNX DRA

Heating actuator, 6-gang with controller for Gira One and KNX DRA plus Features: Heating actuator with integrated room temperature controller for controlling thermal servos for heating and cooling systems. Valve outputs: 6 independent electronic valve outputs. Valve output 1 can be used as a template for other valve outputs. Notification for largest actuator variable is configurable. Servos can be activated with rated voltage 24 V or 230 V. Valve control (open closed while de-energised) can be configured for each output. Variable input: "switching - 1 bit" and "continuous - 1 byte". Valve control: "switching - 1 bit", "continuous - 1 byte PWM" or "continuous - 1 byte variable limit". Configurable status feedback. Failure notification for valve operating voltage is configurable. Overload and short-circuit notification can be set separately for each valve output. Heat demand and pump control. Anti-jamming prevents the pump from jamming. Summer or winter mode can be selected via an object. Each valve outlet can be locked in a forced position. Different corrected variable values can be parameterised for summer and winter mode. Cyclical monitoring for 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 actuation of the outputs independent of the KNX. Reactions in the event of bus voltage failure and recovery can be set for each valve output following an ETS programming process. Various actively transmitting status messages can be delayed globally after a bus voltage recovery or after an ETS programming process. 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 setpoint temperature values. Setpoint temperature specification: relative (derived from basic setpoint) or absolute (separate setpoint temperatures for each operating mode). Presence detection using presence button or presence detector. Switchover of operating modes according to KNX specification. Configurable status feedback. Frost heat protection changeover via window status or temperature drop detection. Operating modes: “Heating", “Cooling" and “Heating and Cooling" respectively with or without additional stage. Various control types can be configured according to the heating or cooling level: PI control (constant or switching PWM) or 2-point control (switching). Different types of heating and cooling can be set. Control parameters for PI controller (proportional range, reset time) and 2-point controller (hysteresis) can be set. Automatic and object-oriented switching between "Heating" and "Cooling". Variable outputs can be disabled via objects. Room temperature measurement using up to two external KNX temperature sensors. Measured value generation by external sensors configurable or cyclic monitoring. The actual and setpoint temperatures can be output to the bus (incl. cyclical) after a parameterisable deviation. Separate or shared variable output in heating or cooling mode (4-pipe or 2-pipe system). Automatic transmission and cycle time for corrected variable output can be parameterised. Variable limitation is possible. Floor temperature limitation possible in heating mode and cooling mode. Setpoint temperature limitation possible in cooling mode. Setpoint temperature increase possible in heating mode. Boost function for faster heating and cooling. Scenes: Up to 64 internal scenes can be configured per controller. Incl. scene memory function and extended scene retrieval (toggling scenes). Logic functions: The device has 8 internal logic functions. Logic gate (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 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 value switch with hysteresis with upper and lower threshold value for 9 different input data formats.Incl. 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. Notes : Valves with the same operating voltage must be connected at all outputs. KNX Data Secure compatible. Firmware can be updated using the Gira ETS Service App (additional software). Installation on DIN top-hat rail.
