STEAM HEATING FEATURES
STEAM OUTDOOR RESET
•
The Genesis Heat-Timer
®
regulates the amount of steam sent to the building based on the outdoor temperature. It uses the Cycle
concept based on the Day and Night Heat Adjustment and Outdoor start to regulate the heat. The colder it gets, the longer the
Cycle-On runs.
NIGHT (SLEEP) SETBACK
•
Whenever the outdoor temperature falls below the Outdoor start, the Genesis Heat-Timer
®
adjusts the Cycle-ON and
Cycle-OFF ratio to hold a constant Day or Night heat level. The Night heat level is for when the building is unoccupied or
tenants are sleeping.
DAY AND NIGHT SCHEDULES
•
The Genesis Heat-Timer
®
has 2 Day (WAKE AND RETURN) and 2 Night (AWAY AND SLEEP) Schedule Period settings for each
day of the week. By setting a Schedule, Day and Night Heat Adjustments, and Outdoor start, you can save energy while providing
comfortable heat to the building. The Night (AWAY/SLEEP) settings allow the Genesis Heat-Timer
®
to reduce the length of the
steam Cycle-ON portion during the night or when building is unoccupied. Each schedule period can have an individual desired
building temperature setting.
SYSTEM OUTPUT
•
The system output relay connects to and operates a combustion air-damper or other boiler room equipment and it will energize
whenever there is a call for the boiler.
BOOST AND EARLY SHUTDOWN
•
The Boost is designed to return the building to its Day (WAKE) heat level after Night (SLEEP) heat level. It does it by running the
burner or valve output for a period of time that depends on the outside temperature.
•
The Early Shutdown is a feature that shifts the Day schedule to Night Setback before the last Night (SLEEP) setting for that day.
The Early Shutdown varies based on Outdoor temperature (OD). The warmer the Outdoor temperature the earlier the
Genesis Heat-Timer
®
Heat-Timer
®
shifts to Night Setback.
