CTE-5202 thermostats can use CSP-5000 series
electronic VAV controllers to operate damper boxes
in the pressure-independent VAV system. As shown
in the diagram, a “requested ow” voltage signal
(AO1) is connected to the CSP-5001 to adjust airow
from minimum to maximum ow according to
space demand. Minimum and maximum ow limit
adjustments can be made at the thermostat or at the
controller.
For cooling, select Sequence 1 (from the CTE-5202
SYSTEM menu). See Change Conguration on
page 6. (This replaces a CTE-5101 or a CTE-5015.)

AND set Changeover to 55° F
For heating, connect a 5K to 10K ohm resistor
between Common and AI1. Select Sequence 1 and
lower the Changeover to the lowest seing (55° F).
See Change Conguration on page 6. The resistor
simulates a changeover sensor and puts the thermo-
stat in Reverse Acting mode. (This replaces a CTE-
5102 with Reverse Acting reset.)
NOTE: If the resistor value is too high, the
thermostat will not go into RA mode. If
the resistor value is too low, the thermostat
may go into setback mode.

5001/5002 Applications Guide.)
