SENSORS FOR THE SOLA HYDRONIC CONTROL
66-1184—01 2
SPECIFICATIONS
Honeywell offers a variety of sensor types for the SOLA
Hydronic Control. Bare leadwires and Molex splice connectors
are available. Sensors may be used for either insertion (into a
well) or strap-on applications.
Complementary parts such as immersion wells, mounting
clamps and spring clips can be found in form number 68-
0040, Immersion Wells and Compression Fittings. The
immersion wells and other complementary parts must be
ordered separately.
