StewMac Temperature Controller for Side Bending Owner’s Manual
OPERATING THE TEMPERATURE CONTROLLER FOR SIDE BENDING
Set the temperature unit
The Temperature Controller can display either Celsius or Fahrenheit.
Confirm the temperature unit before setting the bending temperature range. You
will only need to change this once, the controller will remember your
settings.
Plug in the power cord. Turn on the red switch at the back of the controller, then the black switch on the front. The two switches are a safety feature, both must be switched on for the controller to operate. The screen should display “r2.01 Std”.
Press and hold down the P button (Parameters). You will first see “Atun” displayed. Continue to hold the P button.
When you see the screen display “type”, release the P button.
Press and release the P button to toggle through the menu until you see “unit” displayed in red. The green text will read °F for Fahrenheit or °C for Celsius. Press the up or down arrow buttons to change to your desired unit. Once changed press and release P to continue through the menu.
CAUTION
DO NOT set the temperature with the Heating Blanket or the mo couple plugged
in.
DO NOT turn on the Temperature Controller with the Heating Blanket plugged in
unless it is in the sandwich and ready to bend. This can damage your Heating
Blanket.
Set the temperature range
We recommend bending at 300 degrees, which is also the highest recommended
setting for the Temperature Controller. Most woods bend well at this
temperature, if you are bending softer or lighter colored woods test on scrap
at a lower temperature.
During bending, you can raise or lower the temperature of the blanket within your set range by using the up and down arrow buttons. We recommend setting the temperature range 10 – 20 to between your highest and lowest temperature. For example, if your maximum temperature is 300 degrees, your minimum temperature should be 280 – 290 degrees.
Turn on the controller. The screen should read “r2.01 Std”.
The screen will automatically switch to display the temperatures. The green number shows the current set temperature for the Heating Blanket, the red number is the current temperature measured by the thermonuclear probe. The renumber will appear as dashed lines when the thermonuclear is not plugged in.
Press and hold down the P button. The screen will display “Atun” in red, continue holding.
Next the screen will display “type.” Release the P button.
To set the minimum temperature, press and release the P button until you see “SPELL” (Set Point Low Limit). Then use the up and down arrow buttons to set the desired minimum temperature.
To set the maximum temperature, press the P button again and you will see “SPHL” (Set Point High Limit). Use the up and down arrow buttons to set the desired maximum.
Maximum temperature: Do not exceed 300 degrees as you can scorch the wood and Bending Forms.
Press and release the P button once each time until you see the dashed red lines and green temperature number again.
The unit will remember the last temperature range set when turned back on. Always check the green temperature before plugging in the blanket.
When finished programming the Temperature Controller and after bending, always turn off both the front and rear power switches.
CAUTION
The Temperature Controller DOES NOT automatically shut off. You must turn it
off with both front and rear power switches.
Whenever the heat is on and bending sides DO NOT walk away. It is easy to forget or get distracted.
You can burn your sides or worse…
Overheating or “cooking” your sides can also caseharden them, making them brittle and more prone to cracking.
