CONTROL FEATURES

The Y-Series sequence panel includes:

•Standard Indicator Lights:

Stages 1 to 8: Red, indicates which stages are turned on.

Pump:	Green, indicates that the pump circuit is energized.
Call for Heat:	Green, indicates that a call for heat signal is present.
Control On:	Green, indicates outdoor temperature is below the Outdoor Cutoff Temperature
	potentiometer setting and that the boiler will respond to a call for heat.
Setting Error:	Red, indicates one or more of the on-board settings is incorrect.
Sensor Error:	Red, indicates that the Water or Outdoor Temperature Sensor has an out-of-range reading.

•Adjustment Knobs:

	Reset Ratio:	0.12:1 to 8:1; determines how much the micro-controller calculated Target
		Temperature will change for a given outdoor temperature change.
	Control Band:	1°F to 10°F; the temperature above or below the Target Temperature at which the boiler
		turns off and on.
	Pump Off Delay:	0 to 10 min.; determines when the pump shuts off after entering Outdoor Cutoff mode.
.	Outdoor Cutoff	32°F to 200°F; a warm weather shutdown feature. When the outdoor temperature
	Temperature:	exceeds this setting, the boiler will not fire unless placed in manual override mode.
	Outdoor Cutoff	1°F to 10°F; the number of degrees below the Outdoor Cutoff (O/C)
	Deadband:	Temperature which causes the O/C to reset.
	Boiler On Delay:	0 to 5 min.; sets the time interval between sequential boiler start ups.
	Stage On Delay:	0 to 60 sec.; determines the time delay between stages turning on.
	Max. Water Temp.:	70°F to 235°F; the maximum value that the Target Temperature is allowed to reach.
	Set Point:	40°F to 220°F; the system output temperature desired when the outdoor temperature is
		70°F or, in domestic water applications, the desired water temperature.

•Logic Test Button, Jumper and Switches:

System Test Button (S1):	initiates micro self test which causes the status indicator lights to blink 5 times
	indicating the micro-controller is functioning properly.
Last Stage Jumper (J2):	selects the last active stage used for boiler control.
First Stage #1 Selector (S2):	designates the first stage of each boiler in a multi-boiler system. Switch
	position #1 should always be on.
Mode Selector (S3):	switch #1 selects either Manual or Auto Lead-Lag Mode. Switch #2 provides an
	Outdoor Reset defeat. Switch #3 configures the Y–Series for Master/Slave ganged
	operation. Switch #4 allows the Set Point to be set below 105°F.
Bypass Switches (S5):	allows user to turn on any stage(s) regardless of current settings and
	conditions if, and only if, the pump relay is already activated.
