TC4 Controller Setup & Programming Guide
The TC4 document and videos cover controller setup, factory reset and configuration values. Confirm the equipment type, size and approximate year before selecting the output setting.
- Confirm equipment model and approximate year.
- Confirm the controller face and controller name match.
- Periodically reviewing the programmed values is a useful way to verify that the saved settings have not changed.
- RELAY: Use for every PRIMO 3/25 (3-gallon / 25-lb) unit, every filling system and melters manufactured through 2024.
- SSR: Use only for 2025-and-newer PRIMO melters larger than the PRIMO 3/25 (3-gallon / 25-lb).
- If uncertain, submit a controller photo through guided troubleshooting.
Written TC4 Programming Instructions
Factory Reset the TC4 Controller
- Hold all three buttons until the controller displays INIT.
- Press the left arrow. The controller will display NO. Press the up arrow to select YES. This factory resets the TC4 controller.
Program the TC4 Controller
- Hold the MODE button until you see PAR2. It will display INT. Press the left arrow to change the setting.
- Go to JIC and press MODE to save.
- When the controller displays UNIT, press the left arrow to choose Celsius or Fahrenheit. Domestic units use Fahrenheit. Press MODE to save.
- Press MODE until you see HSU. Set HSU to 212°F for a standard melter. Set HSU to 400°F only for an existing melter with Xtreme upgrade. WaxHand Units to 130F. Press MODE to save.
- Skip OFT and go to C-ND. Press the left arrow to change the setting from PID to ONOFF. Press MODE to save.
- At OUT, select RELAY for every PRIMO 3/25 (3-gallon / 25-lb) unit, every filling system and melters manufactured through 2024. Select SSR only for 2025-and-newer PRIMO melters larger than the PRIMO 3/25. Press MODE to save.
- Change DIY from OFF to STOP.
- Hold the MODE button to save all changes.
- Go to PAR1, then HYS. Press the left arrow, then press the down arrow to change the setting to 1. Press MODE to save.
- Hold MODE to save all changed settings, then set the controller to the required operating temperature.
How to Reprogram a PRIMO Melter Temperature Controller
Output setting: PRIMO 3gal/ 25lb units always use RELAY. Melters manufactured through 2024 use RELAY. For 2025-and-newer PRIMO melters larger than the PRIMO 3gal/ 25lb, use SSR.
How to Reprogram a Filling-System Temperature Controller
Output setting: All WaxMelters filling systems use RELAY.
