OPERATION INSTRUCTIONS
The MSG‑1 snow melting control is designed to send a signal to the MSC‑1 control panel indicating when melting snow or ice
conditions exist. The MSC‑1 control panel uses this information, along with temperature data from the TS‑1 to determine when
de‑icing equipment should be energized.
The MSG‑1 may be tested for functionality if outside temperature is below 3°C (37°F). Apply a small amount of moisture onto
the surface of the sensor wire, the MSC‑1 should energise the heating equipment in the associated zone. After this test, dry the
sensor, the heating equipment in the associated zone should de‑energize after the pre‑set hold time.
At the beginning of the heating season and monthly during operation inspect for and remove all leaves and combustible debris
from roofs gutters and downspouts. At the beginning of the heating season the MSG‑1 must be inspected for physical damage
and the snow sensor surface cleaned. To clean the snow sensor surface:
1. Disconnect MSG‑1 from the power supply.
2. Remove the MSG‑1 sensor housing from the gutter.
3. With a clean wet swab clean up the surface of the snow sensor.
4. Replace the MSG‑1 sensor housing in the gutter.
5. Reconnect MSG‑1 to the power supply.
