Heating actuator, 6-gang with controller for Gira One and KNX

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 with 24 V or 230 V rated voltage can be actuated.
• 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".
• Status feedback is configurable.
• 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 operation 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.
• A range of actively transmitting status messages can be delayed globally after a bus voltage recovery or after anETS 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.
• Status feedback is configurable.
• 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.

Technical data

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.

Scope of supply

• Connection and junction terminal for Gira One and KNX included in scope of supply.
