VAV-SD2A-E No Image The Q340A and Q390A thermocouples

The Q340A and Q390A thermocouples generate a thermoelectric current that senses a pilot flame on gas-fired heating systems

and (1) SPDT switched output

TAX tanks are equipped with butyl diaphragms to separate the air from the system water (glycol)

If used as directed

eventually degrading sensor accuracy

VAV-SD2A-E No Image The Q340A and Q390A thermocouplesThe VAV E lines combine the power and precision that today's modern building applications demand. Fully programmable, these controllers can support a range of applications from complex air handling units to the latest terminal end unit devices, and everything in between.
