Pre Determined Temperature - Thermostat has a pre determined temp. from the factory that determines turn on temp. We recommend using two thermostats therefore activating the low speed at an earlier temperature then the high speed. Please visit www.derale.com for available thermostat options or visit your local retailer. Note: When purchasing a thermostat always consider the maximum amp draw.
