Electric motor-driven servo with one binary input (zero-voltage) for mounting on thermostat valve bases (recommendation: Heimeier) to control heating and cooling systems.
Suitable for room temperature control, e.g. on heaters, radiators, convector heaters and heating circuit distributors on floor heating, etc.
Screwed onto valve head.
M30 × 1.5 mm connection.
Integrated bus coupler. The servo is a proportional drive and can be directly integrated into the KNX system (without additional bus coupler).
Supply voltage is drawn from the KNX system.
Integrated temperature sensor.
Integrated room temperature controller.
Mechanical indicator for valve travel.
Automatic detection of valve travel.
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 auxiliary unit with or without memory function, as a remote temperature sensor or as a temperature limiter for floor heating.
Switching function: two self-contained switching objects available for each input (switch commands can be parameterised individually), separate command can be set for leading and trailing edge (ON, OFF, CHANGE, no reaction).
Dimming function: Single and double-surface operation, time between dimming and switching, telegram repetition and stop-telegram transmission possible.
Blind function: Command can be set with rising edge (no function, UP, DOWN, CHANGE), operating concept can be configured (Step - Move - Step or Move - Step), time between short and long-term operation can be set (only with Step - Move - Step), slat adjustment time can be set.
Value transmitter function: Edge (button as NO contact, button as NC contact, switch) and value with edge can be configured, value adjustment by pressing and holding a button for value transmitters possible.
Lighting scenario auxiliary unit with or without memory function.
Can be used in a heating circuit distributor.
Protection against jammed valves
Corrected variable (1 bit or 1 byte).
Cyclical monitoring of the corrected variable.
Fault message object for drive faults.
Emergency operation via internal temperature sensor.
2 forced settings or 1 forced setting and 1 limit value object can be set.
Minimum and maximum variable limitation can be set.
