Multi-Stage Heat and Cool Control
In a multi-stage system, while maintaining setpoint, several
factors affect when the next stage energizes, such as load
conditions, environmental conditions, P+I control, and home
insulation. The next stage energizes when the thermostat
senses the previous stage is running at 90% capacity. This
operation is droopless control.
