010-OT-DR: 0-10V to Opentherm converter, 1 OT channel, two relays

The 0/10V-to-Opentherm converter can be installed in the electrical panel or inside the chassis of the generator with which it communicates. The converter allows a heat generator to be controlled via Opentherm by an incoming 0/10V signal, managing its temperature and/or power. The converter is equipped with 1 channel for communication via the OpenTherm protocol with a single heat generator. The converter also features 2 output relays that can be used for boiler fault/blockage indication and flame status.

All connections are made using non-removable terminals. The module is equipped with status indicator LEDs:

- LED 1 (green) = Opentherm protocol communication with the boiler active (flashing)
- LED 2 (yellow) = 0/10V input active (signal above 1.5 V)
