4.14 TEMPERATURE PROBE
To check the delivery and return temperature use the two contact sensor. To read the sanitary water
temperature the immersion sensor located on the sanitary outlet is used.
 If the NTCs sensor does not work properly the temperature will be checked by sensor NTC2.
 If the NTC1 sensor does not work properly the antifreeze function will be checked by sensor NTC2 (only
pump circulation).
IMPORTANT!!!! Do not use conducting paste for the contact sensors because they alter the resistance
value.
