Honeywell DR4300 Used for cooling control, 02 to, Cycle Timer for Relay 1 -Use this to specify

			Configuration, Startup, and Operation
				of Recorder with Display
Lower Display	Upper Display			Parameter
Prompt	Range of Setting			Definition
	or Selection
PB2	0.1 % to 999.9 %	PB2 or GAIN 2, RATE2T, and I2 MIN or I2 RPM—
or	or	These parallel their counterparts already described.
GAIN 2	0.1 to 999.9
	[factory setting = 1.0]		ATTENTION	If control group parameter “OUTALG”
		is “RLYD” (relay duplex), “Tcur” (time/current duplex), or
RATE2T	0.08 to 10.00 minutes	“CurT” (current/time duplex), and you are using the
	0.08 or less = OFF	recorder in a heat/cool application, these parameters are
		used for cooling control.
	[factory setting = 0.0]
I2 MIN	0.02 to 50.00
or	[factory setting = 0.02]
I2 RPM

The following parameters are used for time proportional control, and are available only if:

•the control type specified in the control set up group using the “CTRALG” (control algorithm) parameter is “PIDA” or “PDMR”

and

•the output algorithm specified in the control set up group using the “OUTALG” parameter is

“RLY” , “RLYD”, “CurT”, or “Tcur”. In the case of “CurT” and “Tcur”, the cycle parameters apply only to the time-proportioned output.

CYC TI	0 seconds to 120 seconds	CYCLE TIMER FOR RELAY 1—Use this to specify
	[factory setting = 4]	length of total cycle time for time proportional control
		(proportional control using relay action rather than current
		output). In time proportional control the output (0 % to 100
		%) signifies the portion of the cycle for which the relay is
		on (“duty cycle”) to achieve the desired setpoint. For
		example, with a 10-second cycle time and an output value
		of 10 %, the relay would be on for 1 second and off for 9
		seconds.
			ATTENTION	If control group parameter “OUTALG” is
		“RLYD” (relay duplex), and you are using the recorder in
		a heat/cool application, CYC TI is used for heat control.
		Cooling control would use CYC2TI.
CYC2TI	0 seconds to 120 seconds	CYCLE TIMER FOR RELAY 2—This prompt will be
	[factory setting = 4]	displayed only if the control group parameter “OUTALG”
		is set to RLYD (relay duplex).
			ATTENTION	If you are using the recorder in a
		heat/cool application, CYC2TI is used for control of
		cooling.
