Cooling with 3-Stage Reheat
The CTE-5104 electronic thermostat is a dual-
setpoint thermostat for heating (RA) and cooling
(DA) applications. The application below uses an
REE-5001 relay module and three 24 VAC contactors
for three stages of reheat.
The diagram below shows a jumper between “T2”
and terminal “R2” on the thermostat to permit
auxiliary ow. As the temperature drops below
setpoint, the rst stage of reheat begins. As the
temperature continues to drop, the second stage
begins and so on (see the rst chart). This auxiliary
ow is used as a second minimum ow before
enabling the reheat stages.
When the auxiliary ow is not being used (see the
second chart), connect the jumper between terminals
“R2” and “–” and turn the auxiliary dial fully CCW
to ensure it will have no eect.
