Selectra Series 14 systems are designed primarily for make-up air heating, as components of direct fired equipment. A discharge air temperature sensor is mounted within a mixing tube housing

Optional for Series 14:

A room override thermostat provides space temperature control by raising the discharge air temperature to a preselected point - when used in conjunction with the remote temperature selector

A dual temperature selector replaces TD114 to provide dual control for door heaters, or other applications such as paint spray booths

An inlet air sensor (and mixing tube) provides inverse change in discharge air for each degree change in inlet air - when installed in a convenient duct location upstream of the burner
