Kasco C-20 time and temperature controller for deicers is designed to help reduce unnecessary winter run time by operating your compatible Kasco unit only when conditions and schedules call for it.

Built for use with Kasco 120-volt marine de-icers and water circulators, this controller combines two key inputs—temperature and time—to manage operation more efficiently than manual on/off use. Instead of running continuously through cold spells, you can set intervals so your equipment runs when it’s most useful, which can translate into meaningful energy savings depending on your climate and application.

Why use a time + temperature controller?

• Lower operating costs: helps limit runtime during periods when de-icing or circulation isn’t needed.
• More controlled operation: time-based intervals paired with temperature response for better winter management.
• Simple compatibility match: intended for Kasco 120V de-icers and circulators (one controller manages one 120V de-icer).

For best results, allow the controller time to acclimate to ambient outdoor temperature—Kasco recommends a minimum of one hour for the unit to adjust. Once stabilized, the Kasco C-20 time and temperature controller for deicers can help you maintain open water while avoiding excessive power use.

If you’re comparing options, Kasco also offers a temperature-only controller (often referenced as the C-10) that turns equipment on based on temperature without time-based interval control. Choose the approach that fits your winter strategy and energy goals.
