Set Temp Menu
The Set Temp menu items select the operating temperatures of the snow melt system.
Item Field Range Access Description Set to
32 to 95°F
(0.0 to 35.0°C)
Default = 36°F
(2.0°C)

Installer
MELTING
Select the desired surface temperature of the snow melt
surface when melting.
Conditions: Application Mode is set to PWM, Boil, Mix
or Elec.
OFF, 20 to 95°F
(-6.5 to 35.0°C)
Default = OFF
Installer
IDLING
Select the desired surface temperature of the snow melt
surface when idling. Idling pre-heats the slab when the
slab is dry but cold and allows faster reaction time to reach
the melting temperature. Recommended for commercial
use only.
Conditions: Application Mode is set to PWM, Boil, Mix
or Elec.
OFF, 20 to 95°F
(-6.5 to 35.0°C)
Default = 28°F
(-2.0°C)
Installer
STORM
Select the desired surface temperature of the snow melt
surface while operating in the storm operation. Storm
operation temporarily pre-heats the slab to allow faster
reaction time to reach the melting temperature.
Conditions: Application Mode is set to PWM, Boil, Mix
or Elec.
0:30 to 24:00
hours
Default = 4:00

Installer
MANUAL MELT RUN TIME
Select the amount of running time when manually starting
the system.
Conditions: Application Mode is set to PWM, Boil, Mix
or Elec.
0:00 to 6:00
hours
Default = 0:00
hours
Installer
ADDITIONAL MELT TIME
Select the amount of additional melting time after the
Snow / Ice Sensor 090 or 094 is dry. This allows low
spots on the slab to fully dry before the snow melting
system is shut off.
Conditions: Conditions: Application Mode is set to PWM,
Boil, Mix or Elec and a Snow / Ice Sensor is installed or
Track Zone is set to On.
0:30 to 24:00
hours
Default = 8:00
hours
Installer
STORM RUN TIME
Select the amount of storm run time to pre-heat the slab
when advised of a winter storm warning.
Conditions: Application Mode is set to PWM, Boil, Mix or Elec
and Storm is set to a temperature.
AUTO, MIN, -2,
-1, MID, +1, +2,
MAX
Default = AUTO
Installer
WATER SENSITIVITY
Select how sensitive the Snow / Ice Sensor 090 or 094,
or the Snow Sensor 095 is to water detection.
Conditions: Snow / Ice Sensor is set to 090 or 095.
AUTO, 32 to
95°F
(0.0 to 35.0°C)
Default = AUTO
Installer
WARM WEATHER SHUT DOWN
Select the temperature at which to shut down the snow
melting system during warm weather. This allows the
snow or ice to melt off the slab naturally.
Conditions: Application Mode is set to PWM, Boil, Mix
or Elec.
OFF, -30 to 50°F
(-34.5 to 10.0°C)
Default = 10°F
(-12.0°C)
Installer
COLD WEATHER CUT OUT
Select the temperature at which to shut down the snow
melting system during extremely cold weather. Below
this temperature, the heat loss of the slab exceeds the
capacity of the boiler or heating appliance.
