Applications
Cooling or Heating
The CTE-5100 series single-setpoint thermostats are
designed for use with CSP-5000 series electronic VAV
controllers to operate damper boxes and/or valves
in the HVAC system. As shown in the diagram, a
“requested ow” voltage signal (T1 or T2) is wired
to the CSP-5001 to adjust airow 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.
NOTE: CTE-5101 for cooling is shown. For heating,
use CTE-5102, with terminal T2 for input
(“IN”) signal to CSP-5001 controller.
An additional “unrestricted” output (T3 or T4) is
not aected by minimum/maximum limits and
can be used to operate reheat equipment or other
control devices by utilizing REE series relays (some
thermostats vary). See CTE-5100 Series Thermostat
Reference section for details on “T” terminals. The
CTE-5101 has a Direct Acting (DA) reset and the
CTE-5102 employs a Reverse Acting (RA) reset.
NOTE: For use with the CTE-5202 thermostat
instead of the CTE-5100 series, see the
CTE-5202 Applications Guide.
