• On the first power up, the System Startup screen will appear after
the initialization is complete. If it doesn't, the SMC has already been
configured.
• The System Startup menu sets the main operating modes that apply to
the application. These settings must be set by the installer.
PROGRAM SWITCh SETTING
To be able to change the SMC settings the Program/Run Switch must be
set to Program. The switch is located under the Enclosure Wiring Cover
for security.
SENSOR TyPE
Slab, Outdoor
Hold MENU Button: <Settings>/<System Startup>/..../Sensor Type
• If Slab is selected, the SMC shall use the Slab sensor logic and
measure the slab temperature and detect precipitation. See "Slab
Sensor Operation Overview" on page 4.
• If Outdoor is selected, the SMC shall use the Outdoor temperature as
the snow melting guide. See "Outdoor Sensor Operation Overview"
on page 6.
CONTROL MODE
Motorized Valve, Boiler, Ext. Interface
Hold MENU Button: <Settings>/<System Startup>/..../Sensor Type/Control Mode
• The SMC offers three different methods to control the slab heating. See
"Typical Snowmelt Piping Configuration" on page 8.
• The Motorized Valve option controls a floating or modulating (0-10V or
4-20mA) motorized valve. The valve can be a 3-way on the slab loop or
a 2-way controlling steam to a shell-and-tube heat-exchanger.
• The Boiler option operates a 4-20mA or a 0-10V modulating boiler. This
option targets installations using condensing boilers.
• The Ext. Interface option sends a 4-20mA signal as a slab target
temperature to a multi-boiler control (Multi-MOD Platinum, Mini-MOD,
or equivalent). This option will enable the 4mA and 20mA temperature
setting menu.
