General Information

Timers are a beneficial optional accessory when incorporated with any Heat-

Line freeze protection system. Regardless of the overall system length and or 

operating voltage, a Heat-Line Timer will reduce energy costs by decreasing 

overall energy consumption. A Timer can be added to Heat-Line systems in 

order to duty cycle the heating cable at a selected time interval and percentage. 

This field adjustable timer offers true flexibility for repetitive cycle times, and 

offers 8 selectable cycle durations with 30 separate percentage positions for 

ON time periods. To obtain the best results from your investment, please read 

these instructions and acquaint yourself with your purchase before installing 

your new timer. Then follow the installation procedures, one step at a time. 

This will save you time and minimize the risk of damaging the timer and the 

system it controls. 

IMPORTANT! 

Please read all instructions carefully before beginning 

installation. Save them for future reference.

WARNING:

 Only use with 120V-15A or 240V-15A GFCI model Heat-Line 

brand self-regulating heating cable systems.
