Q390A1046/U | Resideo | Combustion & Flame Safety

The Q340A and Q390A thermocouples generate a thermoelectric current that senses a pilot flame on gas-fired heating systems. For easy pilot burner installation, the Q340A and Q390A come with a push-in clip, split nut and an adapter assembly. Each also comes with a male nut connector for Pilotstat® safety control power units and are available in a variety of lead lengths. For situations where a utility grade thermocouple is the best solution, the Q390A is the right choice. It’s an ideal thermocouple for yearly service contract applications and budget-concious customers.
