Features
- Electric motor-driven servo with one binary input (zero-voltage)
for mounting on thermostat valve bases (recommended:
Heimeier) for controlling heating or cooling systems.
- Suitable for room temperature control, e.g. on radiators,
convector heaters or 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, blind, as dimming value transmitter, as
brightness value transmitter, as light scene auxiliary unit with and
without memory function, as remote temperature sensor or as
temperature limiter for underfloor heating.
- Switching function: two independent switching objects are
available for each input (switching commands can parameterised
individually), command for leading and trailing edge can be set
independently (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 limit can be set.
