These resistance values can be checked with an ohmmeter if a defective sensor is suspected. Sensor types and their application: PT 1000: Solar flow, solar return, outdoor sensor PTC (2 kω): All other sensors NTC (10 kω): Electronic safety temperature limiter (estb) Checking the estb Two NTC 10 kω sensors are integrated into the estb. These use the central conductor (pink) as a common earth line (GND). Each individual sensor is measured between the outer and central conductor. F 12-M Subject to technical changes 09.08 25
