Melter controller
How to Reprogram a PRIMO Melter Temperature ControllerOutput 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.
Filler controller
How to Reprogram a Filling-System Temperature ControllerOutput setting: All WaxMelters filling systems use RELAY. Still not operating normally? Continue with Guided TroubleshootingRecord what happened during the video check, then submit the equipment information and results once. WaxMelters can determine whether the next step is operating guidance, component identification, qualified local service, remote assistance, warranty review or factory evaluation.
