Power connection
Power connection terminal is: Input ports
Ground line terminal is GND
Sensor input ports
Input sensor ports T0, T1: for Pt1000 sensors, used for measuring the temperature of
collector and measuring the heat output.
Input sensor ports T2, T3, and T4: for NTC10K, B=3950 sensors, used for measuring
the temperature of tank and pipe.
Advice regarding the installation of temperature sensors:
Only original factory equipped Pt1000 temperature sensors are approved for use with
the collector, it is equipped with 1.5meter silicon cable and suitable for all weather
conditions, the temperature sensor and cable are temperature resistant up to 280
o
C,
not necessary to distinguish the positive and negative polarity of the sensor connection.
Only original factory equipped NTC10K,B=3950 temperature sensors are approved for
use with tank and pipe, it is equipped with 1.5meter PVC cable, and they are
temperature resistant up to 105
o
C, not necessary to distinguish the positive and
negative polarity of the sensor connection.
All sensor cables carry low voltage, and to avoid inductive effects, must not be laid
