PRODUCT DATA
APPLICATION
The Series 2000 C7021, C7023, C7031 and C7041 Electronic
Temperature Sensors are designed for use with electronic
controllers in domestic or commercial heating and cooling
systems.
FEATURES
• C7021D, C7023D, C7031D, C7041D for immersion
mounting sense water temperature.
• C7021F, C7023F, C7031G, C7041F sense outdoor air
temperature and are weatherproof for outdoor use
(knockouts allow for 1/2 in. conduit connection).
• C7021J/R, C7023J/R, C7031J, C7041J/R sense average
duct air temperature.
• C7021B/C, C7023B/C, C7031B, C7041B/C sense duct
air temperature.
• C7021K, C7023K, C7041K with strap-on mounting
senses water temperature.
• C7021N, C7023N, C7041N probe senses water or air
temperature.
• C7021P, C7023P, C7041P senses air temperature.
• Solid state components not affected by dust or dirt.
