CSP-5001/5002 VAV Flow Controller-Actuators 20 Applications Guide, Rev. B
Fan Induction with 2-Stage Electric Heat
NOTE: The fan has an adjustable
start point between 3 and 8
volts.
The CTE-5101 electronic thermostat
is a single-setpoint thermostat for
cooling (DA). In this application, the
thermostat is used with the REE-
5002 relay module, a fan, and two
coils (for two stages of reheat). The
REE-5002 was designed primarily
for use with VAV fan-powered
induction boxes.
If the thermostat drops below
setpoint, the relay senses the
decrease in voltage and starts the
fan. As the temperature continues to
drop, the rst stage of reheat begins,
and the second stage of reheat
follows if the thermostat is still not
satised. The process reverses as the
room temperature begins to rise.
NOTE: The “X” Terminal is used
for measuring fan trip
voltage only.
