Description
Burner control for single burner systems operating on gas, liquid fuel, coal, or combined fuel, automating burner operations and monitoring flame. It runs on 220–240 V, 50–60 Hz, measures 127 mm by 127 mm with a thickness of 133 mm (base Q7800A) or 155 mm (base Q7800B), and weighs 800 g. Five LEDs display the current stage of operation; non-volatile memory retains process history during power outages. It supports external voltage control and accepts interchangeable flame signal amplifiers, and is compatible with Honeywell flame detectors. Ambient temperature range is –40 to +60 °C.

Choosing and fitting
Select a replacement controller by ensuring it matches the existing mounting base (Q7800A or Q7800B) and accepts the same type of flame signal amplifier (e.g., R7824, R7847, R7848, R7849, R7861, R7886). Verify the supply voltage (220–240 V, 50/60 Hz) and the overall thickness required for the enclosure (133 mm with Q7800A base, 155 mm with Q7800B base). Also confirm the accessory connections, such as extension cable sets or remote display brackets.
