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

Function in the Gira One system

• Single-room control possible through fixed controller and valve output pairing.
• Actuator for switching thermal servos in heating and cooling systems.
• The outputs are short-circuit and overload-protected.
• Servos with 24 V or 230 V rated voltage can be actuated.
• Manual actuation of the outputs.
• Heating requirement notification, e.g. on a heat pump in combination with a switching actuator, 1-gang 16 A with binary input, 3-gang (Order no. 5061 00) or switching actuator, 2-gang/blind actuator, 1-gang 16 A with binary input, 3-gang (Order no. 5062 00)

Valve outputs

• 6 independent electronic valve outputs.
• Valve control with the characteristic “de-energised open” or “de-energised closed” can be parameterised for each output.
• Protection against jammed valves by means of smart flushing with a duration of 5 minutes and a cycle of 1 week.
• Boost function for rapid heating of radiators – devices (electric or water-fed).

Room temperature controller

• 6 independent controllers for heating and cooling mode, optimised for the respective heating and cooling system: Floor heating (electric or hydronic), radiators (electric or hydronic), floor cooling
• Heating control type can be set. Continuous PI control or switching 2-point control.
• Operating modes: Comfort, standby, night-time reduction, and frost/heat protection.
• Automatic heating/cooling requirement notification: for this, the actuator continuously evaluates the corrected variables of the assigned outputs and informs the Gira One system if there is a heating/cooling requirement at an output or in a heating/cooling circuit. The connected switching actuator closes or opens its relay depending on the heating/cooling requirement notification. This enables burner and boiler controllers, which possess appropriate control inputs, to be controlled in an energy-efficient manner (e.g. switching between the reduction and comfort setpoint in a central condensing boiler or heat pump according to requirement).
• Limit value specification for floor temperature.
• Manual or automatic window-up detection in the event of a drop in temperature, including specification of the duration of frost protection.
• Window contact query and visualisation in the Smart Home App: An opened window will result in the activation of the frost protection heating mode after a 5 minutes has elapsed.
• Query regarding a heating/cooling switchover, e.g. via the binary input of a heat pump, to allow the current operating mode (heating or cooling) to be forwarded to the heating controller.

Function in the Gira KNX system

• 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 values.
• Setpoint temperature specification: relative (derived from basic setpoint) or absolute (separate setpoint temperatures for each operating mode).
• Automatic transmission and cycle time for corrected variable output can be parameterised.
• Presence detection using presence button or presence detector.
• Switchover of operating modes according to KNX specification.
• 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).
• 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).
