FIREMATE® POWER CONTROL
Thumbwheel Power Control Switch
Power is switched on and the amount of power flowing to your kiln is controlled by the infinitely
variable thumbwheel switch. This is accomplished by cycling off and on (which causes an
intermittent snapping or popping noise). When the “7” to “10” setting is reached, the switch is
100% on and no longer cycles. Viewing inside the dark panel through the top of the panel a blue
light may be seen flashing as the contacts make and break. This is the same thing that happens
every time you switch a light on or off in your home, but the flash is not visible behind its
electrical cover.
Turning the thumbwheel to higher numbers on the dial increases the power that is applied to your
kiln. This percentage power control is turned automatically by the thumbwheel and motor
assembly.
FIREMATE
® Speed Control
This control makes the motor turn the thumbwheel at different speeds (faster or slower). It allows
you to increase the rate of temperature climb and fire at precisely the speed that you want. It stops
the motor when set to the “manual” setting. This allows you to manually turn the thumbwheel
power control as desired.
