Sensors

The sensors installed have the following characteristics:
– Dual sensor (thermal safety/output) NTC R25°C; 10kΩ β25°-
85°C: 3435
– domestic hot water sensor NTC R25°C; 10kΩ β25°-85°C: 3435
– external sensor NTC R25°C; 10kΩ β25°-85°C: 3435
Correspondence of Temperature Detected/Resistance
Examples of reading:
TR=75°C → R=1925Ω
TR=80°C → R=1669Ω.
