Reading Temperature Differential Controller sensors

Hi,
I currently have a TDC connected to two Pt1000 temperature sensors that gets data from the solar panel and the water tank.
I would like to get these two data in home assistant using ESPhome.
From the User manual the pins where the sensor are connected should be around 12V.
How could I read sensor data without disconnect the sensors from the controller? Any suggestion?
This is the controller manual: User manual

Thanks!
