Measure the resistance between either of the white or
black leads and ground lead. This measurement should be
“open”, usually indicated by an “OL” or a “I”. This is the same as
displayed when the test leads are not touching anything.
If there is any change in the reading, record this information
and contact the factory before continuing. This could indicate
damage, test lead problems, or a number of other issues. Try
“pinning” the test leads to the cable lead wires against a hard
non-metal surface if the readings continue to fluctuate.
Change the meter to the 20,000 ohms (20 k) range. Measure
between the lead wires of the SunStat sensor. This resistance
varies according to the temperature sensed. Table 3 provides
approximate resistance-to-temperature values for reference.
Temperature Typical Values
55°F (13°C) 17,000 ohms
65°F (18°C) 13,000 ohms
75°F (24°C) 10,000 ohms
85°F (29°C) 8,000 ohms
