CONTROL PANEL OVERVIEW
3.1 Power Switch: The main power I/O (on/off) switch
controls all power to the unit and must be in the I/ON
position before any systems are operational.
3.2 Main Temperature Control: This control is marked
SET TEMPERATURE and consists of the digital
display and UP/DOWN arrow pads for inputting set
point temperatures and calibration.
3.3 Heating Lamp: This pilot lamp is marked
TEMPERATURE ACTIVATED and is ON when the
unit is heating up to set point and is blinking when
controlling temperature at set point.
3.4 Overtemperature Thermostat: This control is
marked
SET OVERTEMPERATURE and is
completely independent of the Main controller. It acts
as an override in the event that the Main control fails
in the ON position.
3.5 Overtemperature Light: This pilot lamp is marked
OVERTEMPERATURE ACTIVATED and is on when
the thermostat has been activated. Under normal
operating conditions, this pilot light should never be
on.
3.6 Circuit Breaker: (Non-CE units) Adjacent to the
power cord the circuit breaker is an added measure
of protection against power source variations that if
tripped, must be reset by pushing in the button once
the reason for interruption has been cleared.
3.7 Fuse: (CE units only) Located at the back of the unit
within the power inlet, the fuse is an added measure
of protection against power source variations that, if
blown, must be replaced once the reason for the
interruption has been cleared. Note that the unit will
not power up unless the fuse is in place.
