Fan Induction with 2-Stage Electric Heat
In this fan induction application, the CTE-5202
thermostat is used with a REE-4002/5002 relay
module, a fan, and two coils (for two stages of heat).
The REE-4002/5002 was designed primarily for use
with VAV fan-powered induction boxes.
If the temperature drops below setpoint, the REE-
4002/5002 senses the decrease in voltage on AO2 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.
Sequence 1 should be selected from the CTE-5202
SYSTEM menu. See Change Conguration on page 6.
(See also the Fan Box with Reheat section with a
CTE-1101 in the CEP-4000 Series Applications
Guide.)
NOTE: The REE-4002/5002 provides the fan an
adjustable start point. The “X” Terminal is
used for measuring fan trip voltage. See the
REE-5002 Installation Guide or the REE-
4002 Installation Guide for details.
NOTE: Triac outputs on the REE-4002/5002 are for
24 VAC loads only. The phase side of the
transformer connects to the “common” side
of the load (contactors).
