Some states require a sensor that reads the slab's temperature (Colorado, New York, Rhode Island, New Jersey. If so, quote the SCP-120 or Multi Zone Snow controls.
Colorado - Section R403.9 Snowmelt Systems Controls. Snow- and ice-melting systems, supplied through energy service to the building, shall include automatic controls capable of shutting off the system when the pavement temperature is above 50°F, and no precipitation is falling and an automatic or manual control that will allow shutoff when the outdoor temperature is above 40°F.
The SCP -120 and the ZoneBraker will comply with this requirement, since they both come with OT sensors (pavement installed).

From the Code Enforcement Guide: If applicable, do snow- and ice-melting systems include automatic controls configured to shut off the system when the pavement temperature is above 50°F and precipitation is not falling, and control that can shut off when the outdoor temperature is above 40°F? See the attached Screen shot of the code.
The SCP-120 and the ZoneBraker should comply with the requirements of this code, since the control remains off at temperatures above 38 and has a slab temperature OT sensor that can be configured to turn off at 50F. The control also has a manual ON-OFF switch.
Rhode Island Conservation / Energy Code - Section 403.8 Snow melt system controls (Mandatory). Snow- and ice-melting systems, supplied through energy service to the building, shall include automatic controls capable of shutting off the system when the pavement temperature is above 50°F, and no precipitation is falling and an automatic or manual control that will allow shutoff when the outdoor temperature is above 40°F.
The SCP -120 and the ZoneBraker will comply with this requirement, since they both come with OT sensors (pavement installed).
New Jersey
Section R403.9 (N1103.9) of the residential energy code refers to the requirement that any snow and ice melting systems installed on a building must include automatic controls capable of shutting off the system when the pavement temperature is above 50°F (10°C) and precipitation is not falling, alongside a manual or automatic control to shut off when the outdoor temperature exceeds 40°F (4.8°C)
