7.3.11.3.3Operation with NTC 20K room temperature sensor

Instead of the RFF, an NTC 20 room sensor can be connected to a sensor input (VI1-VI3)

Function Configuration is carried out in the "Hydraulics" menu, parameter 08, 09 or 10.

Assignment to the heating circuit to be acted upon by the room sensor is carried out via a fixed heating circuit assignment using parameter settings (e.g. 30 = DC, 31 = MC1, 32 = MC2)

The combined operation of an NTC 20 room sensor and an SDW 10/SDW 30 room sensor for a heating circuit is not possible. If an SDW 10/SDW 30 room sensor is connected, it always has first priority. In this case, the NTC 20 room sensor has no effect. With operation via a connected SDW 30 (room sensor with no effect), an NTC 20 room sensor can be combined with a variable input. With an NTC 20 room sensor connected, all room functions of the heating circuit are in effect ("Direct Heating Circuit", "Mixed Heating Circuit 1" or "Mixed Heating Circuit 2" menu, parameter 4

= active). In conjunction with the NTC 20 room sensor, this means a shift of the controller (software) to the central device. The configuration of the room controller with NTC 20 room sensor operation occurs via additional parameters in the central device menu trees DC/MC1/MC2. The room controller in the SDW 30 functions as before. Room control in conjunction with SDW 10 is not possible.
