HEAT ADJUSTMENT—
STEAM
Selections:
1–16
Default:
5
Description:
•
Heat Adjustments control the duration of Cycle-On based on the outdoor
temperature.
•
An “1” setting gives the least duration of Cycle-On at any given outside
temperature. A “16” setting gives the longest Cycle-On.
•
The Genesis Heat-Timer
®
has two heat levels, Day (WAKE) and Night (SLEEP).
The Day heat level is for when the building is occupied and people are active.
The Night heat level holds a lower ambient temperature, and is for when
the building is unoccupied or people are sleeping. The Day and Night Heat
Adjustment are individually set.
•
The length of the Cycle-ON is based on the Outdoor Cutoff temperature.
Therefore, if you set both the Day and Night Heat Adjustments to the same
value, you will get less heat at Night. For example, with both Heat Adjustments
set to 7 and the Outdoor Cutoffs of 55°F for Day and 40°F for Night, when the
outdoor temperature is 25°F the ON part of the cycle will last for 18 minutes in
Day, and only 8 minutes at Night.
•
If the building is too cold, adjust the appropriate setting up a number (Day Heat
Adjust if it is too cold in the Day (WAKE) heat level time and Night Heat Adjust
if it is too cold in the Night (SLEEP) heat level time). For example; from 6 to 7.
Then wait at least 24 hours before evaluating the new adjustment. Otherwise,
adjust it up another number and wait an additional day for the results.
•
Similarly, if the building is too warm, reduce the Heat Adjustment one number
and wait for 24 hours before making any additional adjustments.
If the average space temperature exceeds the building target temperature, the Genesis
Heat-Timer
®
control will shutdown the boiler or in a District Steam application, close
the valve. This will continue until the average space temperature falls below the
building target temperature. The Genesis Heat-Timer
®
control will then adjust the Heat
Adjustment setting accordingly so that the calculated ON Cycle time is lower.
If the average space temperature is below the building target temperature, the Genesis
Heat-Timer
®
control program will recognize this and automatically adjust the Heat
Adjustment setting to increase the calculated ON Cycle time. This self learning logic
of the Genesis Heat-Timer
®
control allows the installer to select a random ratio Heat
Adjustment setting and allow the program logic to adjust accordingly without worrying
about the tenant comfortable level being compromised.
NOTE
The Heat Adjustment setting is only a starting point as the Genesis
Heat-Timer
®
will automatically adjust the Reset/Heat Adjustment setting
based on the feedback of the building space sensors.
