Description
AXT2**
Thermal valve actuators (see product data sheet)
Description of operation
For individual unitary control (2-point) in residential and business spaces with Triac outputs for up to 6
thermal actuators.
The room temperature is measured by a temperature sensor and compared with the current setpoint.
Depending on the control offset, the heating in the room is increased or reduced. If heating is required, the thermal actuator is activated and the LED lights up.
TRT 217: In reduced mode, the defined temperature is reduced by 3 K.
Intended use
This product is only suitable for the purpose intended by the manufacturer, as described in the “Description of operation” section.
All related product documents must also be adhered to. Changing or converting the product is not admissible.
Engineering and fitting notes
