Specifications
The following are the recommended specifications for the WiFi Snow Melting Control 671.

stops the system.

• The system water temperature shall be based on the outdoor temperature and feedback from sensors located in the snow
melting slabs.
• The control shall have two separate access levels to limit the number of adjustments available to various users.
• The control shall have a manual override that allows each output to be manually turned on or off.
• The control shall continuously monitor its temperature sensors and provide an error message upon a control or sensor failure.
