Cooling with Heating Changeover and Electric Reheat
NOTE: Minimums must be sucient for reheat.
This application utilizes the same controls as Cooling
with Heating Changeover but adds the REE-5001
relay for electric reheat. When the VAV inlet air
temperature becomes warm (such as morning warm-
up), changeover occurs. In this mode, “T2” controls
the CSP-5001. The rst stage of heat is enabled when
the space temperature is slightly above the heating
setpoint (3.5 volts). If the temperature continues to
drop, the second stage of heat comes on, followed
by the third stage. See the chart for reference of each
heat stage activation.

NOTE: REE-1005 terminal “A” can be used to
trigger an auxiliary ow setpoint when
used with a CTE-5104 or REE-1012. This
terminal can also be used to daisy chain
more than one REE-1005 together by wiring
Terminal “A” to Terminal “Y” on the next
relay.
