Attention:
WarmlyYours is not responsible for electricity costs resulting from incorrect switch programming or from leaving the switch on for too long.
It is the end-user’s responsibility to verify that the snow melting system is only powered on, as necessary, to clear snow and ice from the
surface and then switched o in a timely manner after the weather event. If the switch is not correctly programmed or manually turned o in
a timely manner, the system can remain on indefinitely and adversely impact the end-user’s energy bill.
