• Ambient temperature compensation provides good
temperature control.
• Temperature setting scale markings in both Fahrenheit and Celsius.
• Steel case has a clear plastic cover to make setting readily visible.
• Surface mount using two screws through back of case.
Capable of providing on-off temperature control for ducts, tanks, heating
and refrigeration units, greenhouses, animal confinement buildings and
other applications where electronic accuracy in addition to remote
sensing is desired.
• Choose from 1 or 2 SPDT relay models.
• Two stage models can be configured as 2 heat/2 cool,
or 1 heat/1 cool.
• Switch selection of heat or cool mode.
• Temperature sensing up to 400 feet.
