Siemens 125-5050 Switch Dband, CTL Stpt, Flow Stpt, Cal Air, CAL Setup, CAL Timer, Duct Area

			Chapter 3 – Point Database
Descriptor	Address1	Application	Description
			OFF for 5 minutes, and Stage 3 is OFF.
SWITCH DBAND	90	All except	The temperature range in degrees which is compared to the
		2560, 2561, 2597	difference between CTL TEMP and CTL STPT. The difference
			must exceed this value for temperature control mode to
			change over. Changeover is also subject to the active
			temperature control loop output being below SWITCH LIMIT
			(Point 85) and SWITCH TIME being expired.
CTL STPT	{92}	All except	The actual setpoint value being used as input for the active
		2597	temperature control loop.
FLOW STPT	{93}	All except	The setpoint of the flow control loop.
		2597
CAL AIR	{94}	All	YES commands the controller to go through calibration
			sequence for the air velocity transducers. YES is also
			displayed when the calibration sequence is started
			automatically. CAL AIR automatically returns to NO after the
			calibration sequence is completed. Valid input: YES or NO.
CAL SETUP	95	All	The configuration setup code for the calibration sequence
			options.
CAL TIMER	96	All	Time interval, in hours, between the calibration sequence
			initiations if a timed calibration option is selected in CAL
			SETUP.
DUCT AREA	97	All	Area, in square feet (square meters), of the duct where the air
			velocity sensor is located. This is a calculated value
			(calculated by the field panel or computer being used) that
			depends on duct shape and size. It is used in calculating all
			points in units of CFM, CF, LPS and L.
			Valid input: .025 ft2 (.002 m2) through 6.375 ft2 (.5923 m2).
LOOP TIME	98	All except	The time, in seconds, between control loop calculations.
		2597
ERROR STATUS	{99}2	All	The status code indicating any errors detected during
			controller power up. A status of 0 indicates there are no
			problems.
UI 1 CFG	102	All	Configuration point for universal input 1 (digital, analog –
			thermistor, 0 to 10V or 4 to 20mA).
PERCENT UI1	{103}	All	Universal input 1 when configured as 0 to 10V or 4 to 20 mA.
UI2 CFG	104	All	Configuration point for universal input 2 (digital, analog –
			thermistor, 0 to 10V or 4 to 20 mA).
PERCENT UI2	{105}	All	Universal input 2 when configured as 0 to 10V or 4 to 20 mA.
AIR ALTITUDE	106	All	Optional correction factor for flow sensor based on altitude.
TUBE LEN	107	All	Optional correction factor for flow sensor based on tube length
			of air tube pickup.
TUBE DIAMETE	108	All	Tube diameter (inside) of air tube pickup.
AUX TEMP UI2	{109}	All	Temperature sensor (when UI 2 is configured for 10K
			thermistor).
STAT SUPV	126	All	Room unit configuration point, values are additive.
RM RH	127	All	Room humidity when room unit is provided with humidity
			sensing.
