10. Controller On/Off switch. For maximum accuracy of the displayed temperature, turn the controller
on 10 minutes prior to use. WARNING: Due to the nature of solid-state relays, a small amount of
output voltage is present on the outlets even when the controller is not heating. Take appropriate
precautions to avoid electrical shock.
11. Power Reduction Circuit. Limits the maximum power delivered to the heater. See Sections 3.7 and
4.1.
12. Increases or decreases the time remaining in the timer when pressed.
13. This switch, in conjunction with the timer, determines when power is present at the heating outlets.
See Section 3.5. The label ‘When time = 0 turn outlet:’ has reference to the time remaining in the
display 15.
14. Indicates whether the timer section has turned power ON or OFF at the heating outlets. This LED
is lit when the timer will allow power to be present at the heating outlets and off when the timer has
turned the heating outlets off.
15. Displays the time remaining in the timer in the format of ‘Hr:Min’.
3.2 Heater Restrictions. The controller the current and voltage listed in the table below into resistive loads
(heating mantles, hot plates, ovens, etc.). Use only resistive loads that are safely operated at the listed
voltage and require less than the listed current or damage to the controller and a safety hazard may
result.
Model Number Output Voltage Maximum Output Current
HCC-130 120 VAC 30 Amps
HCC-215 220-240 VAC 15 Amps
HCC-230 220-240 VAC 30 Amps
•
Do not plug low voltage oil baths into your controller. Many oil baths are not 120 or
240VAC devices and become a fire hazard unless properly connected to the controller.
•
Devices other than resistive loads can be used with your controller but certain restrictions apply.
Device Type Restrictions Comments
Incandescent lamps
Infrared heaters
≤ 3000 watts
Set the power reduction circuit
to the > 2 L position.
Inductive loads:
* solenoids
* transformers
* motors ≤ 10 amps
≤ 1 horsepower
The controller must be
programmed for this use.
