The HS-3 Heater-Stat is an temperature controlled electrical thermostat outlet. Designed to automatically turn electrical devices on and off when the ambient temperature drops or raises in accordance with a preset temperature setting; the HS-3 is the ideal device to control the operation of the Oil Pan Heater and Battery Warmer or Block Heater.
The HS-3 plugs into an outdoor 120 volt AC electrical outlet and has two 120 volt receptacles. The maximum electrical load is 1800 watts; this will accommodate both the largest oil pan heater, TH1000-1, and the battery warmer, TBH60-1, being plugged in together.
The oil pan heater and the battery warmer will be automatically turned on when the ambient temperature falls below 35°F (2°C) and stay on and until the ambient temperature exceeds 45°F (7°C).
Electrical usage and energy cost is consequently reduced.
