[BLDG-SIM] Creating Annual BaseBoard Heating Sch

BASEBOARD-SCH


Takes the U-name of a SCHEDULE (TYPE=RESET-RATIO) that defines the
relationship between baseboard heat output and outside air temperature, and
specifies the days of the year during which this relationship applies. This
keyword applies only if BASEBOARD-CTRL = OUTDOOR-RESET. If BASEBOARD-CTRL =
THERMOSTATIC, the program will use HEAT-TEMP-SCH to control the baseboards.
Note that the DAY-RESET-SCH keywords SUPPLY-HI and SUPPLY-LO, which usually
specify temperatures, are used here to specify baseboard output as a
fraction of BASEBOARD-RATING. 

You must be careful to avoid shutdown of system heating capability (see
HEATING-SCHEDULE) during periods when baseboard heating is desired. 

Example input:

BASE-DAY-1 = DAY-RESET-SCH
TYPE               = RESET-RATIO
SUPPLY-HI          = 1.0
SUPPLY-LO          = 0.0
OUTSIDE-HI         = 70.0
OUTSIDE-LO         = 0.0  ..

BASE-SCHED-1 = SCHEDULE
TYPE               = RESET-RATIO
THRU DEC 31 (ALL)  BASE-DAY-1 ..

SYS-1 = SYSTEM
BASEBOARD-SCH= BASE-SCHED-1
....

In this example, baseboard heat is fully on for outside temperature below 0F
and decreases linearly to zero when the outside temperature reaches 70F.

If I'm making a baseboard annual heating schedule, what schedule type
(on/off, fraction, temperature, etc) do I need to make it in order for it to
appear as a choice on the drop down list in the "Preht/Basebrd" section of
the associated Air-Side HVAC System Parameters menu???
