Electrical Connection - Line Voltage; Low Voltage Wiring And Diagram; Install Digital Manager - ENERGY KINETICS System 2000 EK1 Frontier Owners And Installation Manual

ELECTRICAL CONNECTION - LINE VOLTAGE

System 2000 requires 120 VAC. The supply voltage must be within 108 VAC min / 132 VAC max for reliable operation
of the boiler and the Manager. An easy way to check the supply voltage is to plug a voltmeter in at the service outlet
located on the side of the system junction box.
DANGER:
Make All Connections with Power Off at Main Circuit Box
Figure 3A: Connect power from a separate 15 AMP fused circuit. Install 3
electrical accessories. The system switch is included so power can be shut off at the unit for servicing.
Pigtails are provided for the line voltage power connection. Connect black pigtail to hot, white pigtail to neutral, and the
green pigtail to ground.
WARNING:
The junction box is wired at the factory with the service outlet always powered, even with the System
Emergency Switch turned off. To have the service outlet controlled by the System Emergency Switch, move the service
outlet black lead to top lug of system switch. A low water cut-off is included on all new systems, but may be field installed
if required by local codes and is available from Energy Kinetics if not included.
LOW VOLTAGE WIRING
WARNING: Make All Connections with Power Off at Main Circuit Box
A typical low voltage wiring diagram for the Digital Manager is shown in Figure 4A. Thermostats must be located
on inside walls away from cold drafts, windows or heat from fireplaces, appliances or sunlight. Set thermostat heat
anticipators to 0.1 amps (or "gas" if gas/electric option). Call Energy Kinetics to request alternate low voltage wiring
diagrams to handle special situations such as air handler wiring, heat pump wiring, isolation relays for thermostats, and
isolation relays for heat motors or circulators, etc.
The single 24-volt/50VA transformer is suitable for the Digital Manager and five zone outputs (zone valves or
relays). NOTICE: Additional load such as extra valves may require greater transformer capacity. To add transformers,
wire in parallel as follows: wire terminal "A" on one transformer to "A" on the other. Repeat with other low voltage terminal
"B". Be sure to verify 24VAC output from all transformers.
The Digital Manager is designed to heat domestic water and up to four (4) heating zones. Use Energy Kinetics
supplied zone valves with two wire connections. For more than four heating zones, use Energy Kinetics 12 zone
expanded Digital Manager, or call Energy Kinetics for alternatives.

INSTALL DIGITAL MANAGER

The Digital Manager is shipped in its own protective shipping box. NOTICE: The option switches can be set very
easily before the Manager is installed. Locate the pre-wired quick connectors fastened to the front of the junction box by
two cable ties. Cut the two cable ties and discard. Fasten the Digital Manager to the junction box with the four corner
screws. Slide the two quick connectors onto the Digital Manager. Label each zone on the manager, using the adhesive
labels supplied.
