CEP-4000 Series VAV Flow Controller-Actuators 17 Applications Guide
Fan Box with Reheat
The CTE-1101 electronic thermostat is a single-
setpoint thermostat for cooling (DA). In this
application, the thermostat is used with the REE-
4002 relay module, a fan, and two coils for two stages
of reheat. The REE-4002 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. Once
the thermostat has reached setpoint, the process
reverses.
NOTE: The transformer must supply a minimum
of 14 VA plus the requirement for the reheat
contactor coils (10 VA max per stage).
