Simply turn the dial to 6.5 and in 5-7 minutes you are at 1500 degrees. Then Lower the setting to your desired firing temperature. I fire at 1400 degrees so I can lower the dial
to 3 – 3.5 and remain there the rest of the day. If you turn the pyrometer to high and walk away you can BURN IT UP. With 120 volts and 1600 watts, is what allows this guy to heat fast and regain it’s temperature quickly when opening the door to check your work.

I can offer a lower volt and watts for those of you that fell you are more comfortable with a slower to temperature kiln. Simply let me know in the instruction section of your order.

The TEC220 Three-button Controller is a highly accurate and customizable instrument. In this installation, the controller’s basic setpoint functions are used to reach your target-temperature rapidly. Once plugged in and after an initial startup sequence, the controller displays the current interior kiln temperature in degrees Fahrenheit (°F). With the “ELEMENTS ON” toggle switch in the UP/ON position, the kiln will immediately begin to heat and will seek the last set target temperature.

To change the target temperature: 

  1. With the toggle in the off position, press the SET key (first key on left) displays SPI.
  2. Press the center key to display the set temperature, and adjust using the “UP” or “DOWN” Arrow keys.
  3. Press the SET key  (first key on left) to display SPI
  4. Pressing again will display “SP2”  which  indicates a default safety over-temperature limit.  Press again to displays “H100” Factory set to keeps the unit from over firing.
  5. Press the set key  again to display the current temperature.

Opening the kiln’s door during heating will cause the temperature to drop quickly. Temperature recovery to your set point temperature is rapid.

Be aware that the kiln’s elements are “ON” and may have live 120 volts to them when the toggle is in the UP/ON position. Always flip the toggle to the “elements off” when finished firing.

General Information

The Model 3K controller with RMPATE software has four User programs. Each program can have up to eight segments with each segment consisting of a ramp rate (in degrees per hour), a target temperature, and a hold time. Programming consists of choosing the User program (1, 2, 3 or 4), choosing how many segments you want (up to 8), then programming the ramp (rA), temperature ( °F), and hold time (HLD) for each segment.

Programming the Model 3K Controller with RMPATE Software

When the power is first turned on either ErrP or IdLE alternating with the current temperature is displayed.

If ErrP is displayed press the up arrow to clear this error message.

If IdLE alternating with the current temperature is displayed, you are ready to begin programming.

Press ENTER to begin. 
The previously fired program will be displayed, either USr1, USr2, USr3, or USr4. Select the user number you want to program by using the UP and DOWN keys, and press ENTER.

dELA is displayed alternating with 00:00. Press ENTER if no delay is wanted. When firing glass no delay is used. Use the UP and DOWN keys to delay the start of the firing (Hours: Minutes). Press ENTER when the desired delay time is displayed.

SEG alternating with the last selected number of segments is displayed. Use the UP and DOWN keys to select the number of segments, then press ENTER. 
       NOTE: Each segment consists of a ramp rate to a temperature and a hold time. There are 8 segments available for programming.

rA 1 alternates with the ramp rate ( °/hr). Use the UP and DOWN keys to select the desired rate and press ENTER. A rate of 9999 will cause the kiln to heat (or cool if in a down ramp) at maximum rate. The first segment must always be an “up” ramp.

°F 1 alternates with the currently selected temperature. Use the UP and DOWN keys to select the desired temperature for this segment and press ENTER.

HLd1 alternates with the currently selected hold time. Use the UP and DOWN keys to select the desired hold time for this segment and press ENTER.

This completes programming for the first segment. If more than one segment was chosen then rA 2 will be displayed and you repeat the steps for ramp rate, temperature, and hold time for each additional segment selected.

rEdl will be displayed after the last segment is entered.

Press START to begin firing.

Firing Example: Tack Fuse Glass Firing Program programmed in User 1 with no delay

Segment Rate (°/hour) °F Hold time (hours.minutes)
1 750 750 00.10
2 500 1350 00.15
3 9999 1000 00.30
4 200 975 00.15

To program this example (from idle):

  1. Press ENTER – the display will show Usrx, where “x” is the last fired program number.
  2. Use the arrow keys to adjust “x” to 1 for user 1
  3. Press ENTER – dELA/00.00 will be displayed
  4. Press ENTER – SEG/000x will be displayed, where “x” is the number of segments previously in the program.
  5. Use the arrow keys to display 4
  6. Press ENTER – the display will show rA 1/xxxx, where “xxxx” is the last saved rate for ramp one.
  7. Use the arrow keys to adjust the rate to 750
  8. Press ENTER – the display will show °F 1/xxxx, where “xxxx” is the previous segment 1 temperature.
  9. Use the arrow keys to adjust the temperature to 750
  10. Press ENTER – the display will show HLd1/xxxx, where “xxxx” is the last saved hold time.
  11. Use the arrow keys to adjust to 00.10 for a 10-minute hold time
  12. Press ENTER – the display will show rA 2/xxxx
  13. Repeat steps 6 – 12 filling in the information for each additional segment from the table.

To re-fire the last used program, press the DOWN key when IdLE is displayed. The program will be quickly reviewed and rEdl will be displayed. Press START to begin the firing.

Options During Firing

During a firing you may advance from the current segment to the next ramp rate by using Skip Step. If you are in a hold period you may add time or add temperature to the hold period.

Displaying the current set-point and accessing the following options    When the UP key is pressed during a firing the current ramp or hold is displayed followed by the current or traveling set-point, then SStP is displayed. If you do not press a key within several seconds the display will return to showing the current temperature in the kiln.

Skip Step    This option allows you to skip from the present segment to the next ramp rate. Press the UP key, the display will show the current segment, then the set-point, then SStP. When SStP is displayed press ENTER to skip to the next ramp rate.

Add Time to Hold Period    This option allows you to add time in 5 minute increments to a hold (soak) period. When in a hold period (during a hold or soak, the temperature in the kiln will be alternating in the display with the remaining hold time), press the UP key. When SStP is displayed press the UP key again and tME will be displayed. Press ENTER and 5 minutes will be added to the hold time. You may use this procedure as many times as necessary to get the hold time that you want.

Add Temperature to Hold Period    This option allows you to add temperature in 5 degree increments to a hold (soak) period. When in a hold period (during a hold or soak, the temperature in the kiln will be alternating in the display with the remaining hold time), press the UP key. When SStP is displayed press the UP key twice more and tMP will be displayed. Press ENTER and 5 minutes will be added to the hold time. You may use this procedure as many times as necessary to get the hold temperature that you want.

Error Codes

Err1   Error 1 indicates the temperature in the kiln is rising during an up ramp slower than 15 °F/hr. If this rate continues for 8 minutes the firing will be stopped. Err1 may be an indication that the elements are worn or that a relay has stopped working.

ErrF   Error F indicates the temperature in the kiln is decreasing during a down ramp less than 15 °F/hr. If this rate continues for 8 minutes the firing will be stopped. ErrF may be an indication that a relay has stuck in the on position.

Errd   Error d indicates that the kiln temperature is 100 °F above the traveling set-point, which is the current desired temperature in the kiln. The traveling set-point will increase or decrease according to the programmed rate. Errd may indicate a relay stuck in the on position or a problem with a thermocouple not reading correctly.

ErrP   ErrP is displayed whenever there is a power interruption that is long enough to stop the firing. If the power interruption is brief the kiln will continue to fire when power is restored; in this case there will be no indication of a power failure. To clear the error, press any key.

tC FAIL   tC alternating with FAIL indicates the thermocouple has failed. Replace the defective thermocouple. To clear the error, press any key.

tC- –   The red and yellow thermocouple wires are reversed.
