Heating
If staged heating is used, the Room Controller measures the zone temperature and turns
on the first and second stage heating (if available) as needed to maintain the heating
setpoint. A 5-minute delay between stages prevents short cycling, and each stage has a 1-
minute minimum on time and a 1-minute minute minimum off time.
If hot water heating is used, the Room Controller measures the zone temperature and
modulates the heating analog output to maintain the heating setpoint.
