POWER TEMPERATURE CONTROLLER
4
Start the heater with a 0º (F or C) Set-Point (SV): This will ensure the output signal to the power
control starts off low (0% output) before the contactor is engaged and immediately applying
full power.

Use proper closed loop control (PID) settings. TUTCO SureHeat typically uses the following PID;
Proportional (P), Integral (I) and Derivative (D); settings as a starting point for stable temperature
control. Some manual tuning may be required for more precise control.

Incorporate a Ramp Rate for the start-up of the heater. The slower the ramp to the final set-point
the less temperature overshoot the system will incur and other related problems the system will
have. Typically; TUTCO SureHeat heaters should be ramped up over a period of several minutes.
The following are recommended ramp rates based on final temperature. (For custom ramp rates
consult with factory)
Set-Point Temperature
Ramp per Minute
• Up to 600ºF (up to 300ºC)
360ºF (150ºC)
• 601-1000ºF (301-500ºC)
240ºF (100ºC)
• 1001-1400ºF (501-760ºC)
120ºF (50ºC)
OPTIONAL:

Reduce the output of the temperature controller.
Most temperature controllers default to 100%
output as its high limit value. This value can be reduced as most air heaters are oversized for the
application and don’t need 100% power to achieve the desired output. Consult with TUTCO
SureHeat technical support.
