Description Range Access
APPLICATION MODE
The Application Mode selects the operation of the mechanical equipment.
Application Mode “PWM Zone” operates a pump or zone valve to provide heat to the snow melting
system.
Application Mode “Mixing” operates a mixing valve or a variable speed injection mixing pump to
heat the snow melting system. The heat source is enabled.
Application Mode “Boiler” operates a modulating, 1-stage or 2-stage boiler to heat the snow melting
system.
Application Mode “Boiler+Mix" operates a mixing valve or a variable speed injection mixing pump
and controls the boiler temperature to heat the snow melting system.
Application Mode “Electric” uses electric cables to heat the snow melting system.
Conditions: Always available.

Installer
SNOW/ICE SENSOR 1
Select if a Snow/Ice Sensor 090 or 094 (In-slab), or a Snow Sensor 095 (Aerial) is installed
on the Snow/Ice Sensor 1 input.
Conditions: Always available.
None, In-slab,
Aerial
Default = In-slab
Installer
SLAB SENSOR 1
Select if a Slab Sensor 072 or 073 is installed on the Slab Sensor 1 input.
Conditions: Available when snow/ice sensor 1 is set to None or Aerial.
Off or On
Default = Off
Installer
SNOW/ICE SENSOR 2
Select if a Snow/Ice Sensor 090 or 094 (In-slab), or a Snow Sensor 095 (Aerial) is installed
on the Snow/Ice Sensor 2 input.
Conditions: Always available.
None, In-slab,
Aerial
Default = None
Installer
SLAB SENSOR 2
Select if a Slab Sensor 072 or 073 is installed on the Slab Sensor 2 input.
Conditions:
Available when snow/ice sensor 2 is set to None or Aerial.
Off or On
Default = Off
Installer
SLAB PROTECTION
Select if a concrete slab should be protected from large temperature differentials to avoid
cracking the concrete due to high tensile stress. This limits the heat-up rate of the concrete
slab. Slab protection is not required for installations with brick pavers, asphalt or other
non-concrete materials.
Conditions: Available when 1) Application mode is set to Mixing, Boiler or Boiler+Mix, 2)
Snow/ice sensor 1 or 2 is set to 090 or Slab sensor 1 or 2 is set to On.
Off or On
Default = On
Installer
ECONOMELT
EconoMelt allows the user to mechanically remove snow then manually start the system to
melt the remaining thin snow layer or ice.
Conditions: Available when snow/ice sensor 1 or 2 is set to In-slab.
Off or On
Default = Off
Installer
MAX MELT DAYS
Limit the amount of melting run time after snow is automatically detected by a Snow/Ice
Sensor 090 or 094, or a Snow Sensor 095.
Conditions: Always available.
Off, 0.5 to 7 days
Default = 3 days
Installer
OUTDOOR SENSOR
Select if the outdoor air temperature is measured by the control or if the BAS system
communicates the outdoor air temperature.
Conditions: Always available.
Control or BAS
Default = Control
