|
|
Controller For Snow Melting Systems |
|
|
|
|
Application: |
|
ETS is a 24 volt snow melting controller capable |
|
|
|
of switching an outdoor heating system on/o |
|
|
|
based on temperature and precipitation. Snow |
|
|
|
melt controller applications can include snow |
|
|
|
removal in walkways, steps, driveways, garage |
|
|
|
entrances, gutters, loading platforms or other |
|
|
|
locations where ice and snow accumulation is |
|
|
|
a problem. ETS detects outdoor temperature, |
|
|
|
ground temperature, and moisture, and |
|
|
|
energizes electrical relays when snow or ice |
|
|
|
occurs. The system’s heat source can be either |
|
|
|
hydronic or electric heating cables (with the use |
|
|
|
of an external relay). |

• |
Detects moisture and temperature, or |
|
|
• |
temperature only |
|
|
Choice of ground, gutter, or outdoor sensor |
|
|
|
• |
Several sensors can be connected to the |
|
|
• |
controller |
|
|
Selection of either temperature or |
|
|
|
temperature/moisture activation of controller
