Glowworm Micron 30 40 50 FF Thermistor Control 2000802635

Glowworm Thermistor Control 2000802635

Rare part, now unavailable from most other suppliers.

Suitable for the following Glowworm boilers:

• Glowworm Micron 30 FF
• Glowworm Micron 40 FF
• Glowworm Micron 50 FF

The thermistor decreases circuit resistance in line with temperature increases.

A boiler’s printed control board (PCB) sends a current to the thermistor, deciding whether a decrease or increase in heat is required by reading the relative resistance.
