- Gas regulation
- Hot surface ignition
- Flame supervision using flame rectification sensing through the igniter. This flame sense circuit uses patented technology to create a robust sensing signal that is independent of AC line polarity and appliance earth grounding
- Water temperature sensing using NTC sensors potted in a submersion well assembly
- Manually resettable High Temperature Cutout (TCO)
- Induced draft blower motor control
- Draft proving via pressure switch
- Retains up to 10 fault code histories in non-volatile memory (available through the EnviraCOM™ communication port)
- Solid state setpoint adjustment over a factory preset temperature range using a linear potentiometer to provide high resolution adjustment
