Cooling And 3-Stage Reheat - KMC Controls CTE-5202 Application Manual

Cooling and 3-Stage Reheat

This application uses a CSP-5001 along with an
REE-5001 relay module and three 24 VAC contactors
for three stages of reheat.
As the temperature drops below setpoint, the first
stage of reheat begins. As the temperature continues
to drop, the second stage and later the third stage
begin as needed.
