Gira 217600 actuator 3 KNX

KNX actuator 3

Features:
Electromotoric actuator with a binary input (potential-free) for mounting on thermostat valve bodies (recommendation: Heimeier) for controlling heating or cooling systems.
Suitable for room temperature control, e.g. on radiators, convectors or heating circuit distributors on underfloor heating, etc.
Screw onto valve head.
Connection M301.5 mm.
Integrated bus coupler. The actuator is a proportional drive and can be integrated directly (without an additional bus coupler) into the KNX system.
Supply voltage is obtained from the KNX system.
Integrated temperature sensor.
Integrated room temperature controller.
Mechanical display of the valve stroke.
Automatic detection of the valve stroke.
One input. This can be used as a binary input or for connecting an external temperature sensor with the following functions: switching, dimming, blinds, as a dimming value transmitter, as a temperature value transmitter, as a brightness value transmitter, as a light scene extension with and without memory function, as a remote temperature sensor or as a temperature limiter for underfloor heating.
Switching function: two independent switching objects available for each input (switching commands can be individually parameterized), command can be set independently on rising and falling edges (ON, OFF, TOGGLE, no reaction).
Dimming function: single-surface and double-surface operation, time between dimming and switching, telegram repetition and stop telegram sending possible.
Blinds function: command can be set on rising edges (no function, UP, DOWN, TOGGLE), operating concept can be parameterized (Step
Move
Step or Move
Step), time between short and long-term operation can be set (only with Step
Move
Step), slat adjustment time adjustable.
Value sensor function: edge (button as normally open contact, button as normally closed contact, switch) and value at edge can be parameterized, value adjustment for button via long button press for value sensor possible.
Light scene extension with or without memory function.
Can be used in heating circuit distributor.
Protection against stuck valves
Control variable (1 bit or 1 byte).
Cyclic monitoring of the control variable.
Fault message object in the event of a drive error.
Emergency operation via internal temperature sensor.
2 forced positions or 1 forced position and 1 limit value object can be set.
Minimum and maximum control variable limit can be set.

Notes:
In the basic setting, the actuator fits valve bases from Heimeier. Use adapters for valve bases from other manufacturers.
