overload.
Solid-state printed circuit board insulated against corrosion
on conductor paths. Contains transient voltage suppressor
to protect controls against transient voltage spikes. Provides
solid state switches for arc-free operation.
Hot gas bypass low ambient control to permit operation
without freezing at outdoor ambient temperatures as low
as 45°F (7°C).
Environmentally sealed on-off switch and gold plated
contacts in thermostat for corrosion resistance.
Electrodeposited epoxy primer and alkyd enamel, both

Control Panel

Function Control (Power)
This switch is a double pole, single throw toggle switch.
ON - Turns everything on.
OFF - Turns everything off.
Temperature Control
The knob at the bottom is the thermostat which is a cross ambient
type used to maintain the desired comfort level. The thermostat
reacts only to a change in temperature at the bulb location - turn
the knob clockwise to set cooler, counterclockwise for warmer.
