Information about slab
and outdoor conditions
SYSTEM IS MELTING
• The control has either detected snow/ice and automatically started or the control was manually
started.
• "Warming Up" is shown when the slab is below the slab target temperature.
SYSTEM IS OFF
• The snow melting system is off and is ready to detect snow or ice.
• "Warm Weather Shut Down" is shown when the slab and outdoor temperature are above the
WWSD setting. During WWSD, the snow will melt naturally due to warm outdoor temperatures.
• "Cold Weather Shut Down" is shown when the outdoor temperature is below the CWCO setpoint.
The outdoor temperature is so cold the heating system does not have capacity to melt snow.
• "Melt Pending" is shown when the system is off during CWCO but will resume melting once the
outdoor temperature increases above the CWCO setpoint.
SYSTEM IS IDLING
• The control is pre-heating the slab to the idling setpoint. This reduces the amount of time needed
to reach the melting setpoint in the event snow or ice is detected.
STORM PREDICTED
• The Internet weather forecast is predicting a snow fall and the control is pre-heating the slab to
the storm setpoint. This reduces the amount of time needed to reach the melting setpoint in the
event snow or ice is detected.
SYSTEM IN OVERRIDE / SYSTEM IN EXERCISING
• The control is in a manual override for testing, commissioning or exercising.
• The description field explains which type of override is active.
