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 sett

INSTALLATION AND MOUNTING If the Y–Series Electronic Boiler Control was not mounted on the boiler by the factory, care should be taken to select a suitable mounting location. The control should be mounted on a solid and permanent base. The control enclosure is NEMA 3R rated, rainproof and sleet resistant, and can be mounted outdoors if required. The unit should be readily accessible for maintenance and installation purposes, and should be mounted so that the indicating lights are at a height a

WATER TEMPERATURE SENSOR INSTALLATION DOMESTIC HOT WATER INSTALLATIONS Y-Series Controller Fig. # 9497.1 Air temperature sensor must be installed across air temperature sensor contacts. The sensor is not activated and can be left stored in controller enclosure. DOMESTIC HOT WATER APPLICATION SETUP PROCEDURE 1. Install a 10,000 Ohm, 1/8 Watt resistor between pins 1 and 2 on P2 connector (see pg. 13), in place of the Outdoor Air Temperature Sensor. The Outdoor Air Temperature will appear to be a

SEQUENCE OF OPERATION 1. When the reset is enabled, the Y-Series Control continously monitors outdoor temperature using the outdoor temperature sensor. When the outdoor temperature falls below the outdoor cutoff tempersture, the Control becomes active and closes the primary pump relay, energizing the primary system circulating pump. The Control then monitors the system supply water temperature. The microprocessor calculates an optimum target water temperature within selectable limits of the cont

CONTROL FUNCTIONS RESET RATIO The Reset Ratio setting determines how much the Target Temperature will increase as the outdoor temperature drops. The Reset Ratio is expressed in the following manner: X:Y X - change in outdoor temperature Y - change in Target Temperature The first number in the ratio refers to the change in outdoor temperature in degrees Fahren- heit below outdoor cutoff while the second refers to the change in the computed Target Temperature in degrees Fahrenheit. A Reset Ratio

RESET RATIO CHART PUMP TURN-OFF DELAY The Pump Turnoff Delay works in conjunction with the Outdoor Cutoff Temperature. The Pump Turnoff Delay sets the delay between the time when the Outdoor Cutoff Temperature is reached and the time when the pump is turned off. The Pump Turnoff Delay is adjustable from 0 to 10 min. Recommended Initial Setting for Pump Off Delay is 3 min 20
