Section D1: Snow Melting Enable
The snow melting system can be enabled manually or automatically. A melting enable signal applied to the control places the system
into the Melting mode. If a melting enable signal is applied once the system is already in the Melting mode, the control responds to
the last command received.
MANUAL MELTING ENABLE
A manual melting enable signal requires the user to manually start the snow melting system and can be provided from the Start
button on the control, Remote Start / Stop Module 039, Remote Display Module 040, or an external melt demand.
