These controls open an integral pneumatic switch
when sensed temperature reaches the control
setpoint.
Features:
• Reduces installation cost when temperature sensing point
is located a considerable distance from the motor starter of
an air-handling unit supply fan.
• N100-2509 and N100-2513 respond when any one foot of
the 20 foot sensing element drops below setpoint.
• If used with DPDT P/E Switch, one circuit of P/E can (for
example) open to de-energize a fan motor starter, while the
other circuit closes to initiate an alarm.
