INSTALLATION INSTRUCTIONS

Operator: Save these instructions for future use!

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.

The Type 1A65/1A65W Electric Heat Thermostat is designed for use on all types of electrical heating installations such as cable heat, baseboards, wall insert heaters, etc. Its narrow operating differential and the ability of its fully exposed knob to sense both radiant heat and room air temperature make this control ideal for use on such installations.

Dial Setting: Knob may be set anywhere between 40° and 85°F by simply turning knob so that indicator on knob points to the desired setting.
