6 MSC‑1
Installation & Operating Instructions
Manual Operation
The power to any one of the snow‑melting zones may be
activated manually by pressing and holding the ZONE X
button until the information below appears on the LCD screen.
Manual activation will only work as long as the ambient
temperature is below the MSC‑1 shut‑off temperature. The
duration of the time the zone will remain energized (Time
Delay) is pre‑set to 2.0 hours; this can be adjusted by following
the programming instructions below.
The minimum and maximum settings possible are noted on
the LCD, adjustable in 0.5 hour increments.
Pressing UP increases the delay time.
Pressing DOWN decreases the delay time.
Press the SET button to accept the chosen delay time.
Once the delay time is set, the MSC‑1 returns to normal
control function, and energizes the heating equipment for
the selected zone.
To de‑energize the manually activated heating equipment,
turn off using the toggle switch on the front panel.
When operating in Mode 2 – Priority, the manual override
works as described if no snow melting zones are energized.
If any snow‑melting zone is energized the manual override
only works to energize the higher priority zone, thereby de‑
energizing the lower priority zone.
It is important to note that manual operation is not possible if
the MSC‑1 has already energized the zone, and that manual
control will be overridden if the zone moisture sensor detects
precipitation.
LCD Explanation
Programming Instructions
The MSC‑1 program has been structured into 6 levels; within
each of these levels are further degrees of selection. Each
programming step is clearly described on the LCD, and easily
adjusted by the “UP”, “DOWN”, and “SET” buttons.
During programming:
·
All regular operating functions of the MSC‑1 are
suspended.
·
If a button is not pressed for approximately 90 seconds,
the program will return to normal operation, saving
programming changes made up to the point exited.
·
Pressing the BACK button results in an exit from the
programming sequence, with the changes made up to
that point saved.
Resetting to Factory Conditions
When the MSC‑1 is first energized, and during the time the
initial LCD display (MSC Ver. X.X) screen shows push the UP
and DOWN buttons simultaneously to access the option to
revert to factory set conditions. Use the UP or DOWN button
to select “yes” or “no”; the program accepts the selection and
returns to normal operation.
To begin programming the MSC‑1 hold the SET button down
for 5 seconds. The display will start in program level 1. To
move to other levels use the UP or DOWN buttons.
Level 1. Temperature Unit Selection
The default temperature units setting is°F.
To move to the next level use the UP or DOWN buttons. Press
the SET button to select the temperature display units.
Pressing UP selects Degrees C.
Pressing DOWN selects Degrees F.
After pressing the UP or DOWN button, the program
automatically accepts the selection and advances to the next
program level.
Level 2. Operating Mode Selection
The default mode setting is Mode 1.
To move to the next level use the UP or DOWN buttons.
Press the SET button to select the operating mode.
Pressing UP selects Mode 1 (Independent).

After pressing the UP button for Mode 1, the program
automatically accepts the selection and advances to the next
program level.
After pressing the DOWN button for Mode 2, the program
automatically accepts the selection and then moves to another
input screen, as shown below.
