    Is this a single pole application or double? is there a difference in options ie fan control only, etc..

    1 answer

    1. This item is a single pole unit. The difference between a single pole and a double pole thermostat is as follows: a single pole thermostat breaks only one side of the power line to your heater and cannot be turned off while a double pole breaks both sides of the power line. All power to the heater is interrupted and is safeguarded if the item requires any maintenance.
