Installation & Operating Instructions
This model is designed and equipped to handle various combinations of zone pumps, various zone valve
types, actuators, etc. The one control board has wiring arrangements for all zone operating devices.
A major feature is built-in automatic stage shedding based upon the capacity of each active zone. This
compensates for any mixture of large and small zones.
Note: Capacity and SIZE dial switches must be set during installation.
Convenience of an attractive wiring center, all connections at easily accessed terminal blocks, LED's, and
simplified zone system installation are also basic to this model.
Special automatic or built-in shift to higher water temperature for priority zone 1. In many combination
temperature installations this feature eliminates mixing valve or injection pump temperature control.

Boiler Circulator/Pump Information The pump connection and operation to the main boiler depends upon the zone arrangement detailed in the previous section. 1. With zone pumps, you do not use or wire to the zone pump terminal block in the boiler itself. 2. -
Page 10: Field Setup Or Programming
Field Setup or Programming Setup – Zone Sizes and Boiler Stage Sizes On the EB-Z**8 zone controller board there are 9 dial switches. Eight relate to each zone and one relates to boiler size information. If all eight zones are not present or used, set the unused dials to 0. From building design information and/or zone capacity calculations, installer must know the approximate Btu/h capacity of each zone. - Page 11 Multiple Boilers, Using EB-C-STG5 Staging Relay It is assumed the zoning arrangement has one or two small zones which can be handled by the first boiler and primarily large zones which will require stepping up to the next boilers. There are three boiler size settings and the first decision relates to proper zone connection and discerning the large zones wired into this zone controller.
- Page 12 7. With stat 1 input and priority switch on, the boiler outlet temperature will regulate at one of two preset values: 150° F or 180° F. At the boiler main control board (hinged door) approximate center left side is a 2-pin jumper associated with the markings J7.

The number of stages will depend upon capacity calculations from the settings. The capacity dial switch position has an assigned value: 15,000 Btu/h = 0 30,000 Btu/h = 1 45,000 Btu/h = 2 60,000 Btu/h = 3 As the zone stats turn on and off these are added for a boiler staging sum. This sum value controls stage per: 1 = Stage 1 2 = Stage 2... -
Page 14: Power On, Start Up
Power On, Start Up Operational Test 1. Thermostat and zone reaction – as each thermostat is turned up there should be an appropriate reaction from the zone pump connected to the correct zone output number and zone thermostat. LED’s for stat input, mode of operation (see diagnostic LED) and bulb lights for zone outputs should follow their appropriate inputs. -
Page 15: Troubleshooting Helps
Troubleshooting Helps Troubleshooting 1. The LED’s on this zone control board should provide adequate indication of inputs and outputs. 2. See previous description on priority and dual temp arrangement. 3. If troubleshooting the complete boiler system indicates the desire to unplug the remote bus connector to verify whether or not the zone controller is interacting with the main boiler board, the main boiler must be reset (power off and on) whenever the remote bus cable is unplugged or plugged back in. - Page 16 Zone Board Functions, 5406 Stat W inputs – external contact between R and W 1 through 8 terminal block.
