Accel CS Boiler - Gas Heat - Eighth Edition – January, 2015 35
The boiler must be electrically bonded to ground in accordance with the requirements of the authority having jurisdiction or,
in the absence of such requirements, with the National Electrical Code, ANSI/NFPA 70 and/or the Canadian Electrical Code
Part I, CSA C22.1, Electrical Code.
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation.
SURGE SUPPRESSION
The Printed Circuit Terminal Board in the Accel CS boiler is equipped with built-in surge suppression.
HYDRONIC CIRCULATORS
The Accel CS boiler is designed to work with up to three hydronic circulators. The Sola boiler control includes three
relays that will control hydronic circulators. Hydronic circulators must be listed (such as the UL listing code REUZ) by a
nationally recognized testing laboratory and when controlled directly by the Sola boiler control, the circulators must be rated
at 2.2 amps or less. Hydronic circulators rated at more than 2.2 amps require additional power control relays (not included)
where the additional power control relay coils will be controlled by the Sola boiler control relays. In other words, when
running a very large circulator, you must add an appropriately rated circulator relay that controls a separate source of
120VAC to power the large circulator. The circulator relay coil will be wired to be pulled in by the Sola boiler control relay.
Call Energy Kinetics and request wiring instructions for this unusual situation.
LOW VOLTAGE WIRING
The low voltage controls on the Accel CS boiler operate on 24 VAC, 60 Hz power. Low voltage must be supplied by two
individual, Class 2, 50 VA transformers. The Sola boiler control requires one 50 VA transformer and the Condensing
Energy Manager requires another separate 50 VA transformer. These transformers must remain isolated from each other.
WARNING: Make All Connections with Power Disconnect Turned Off at Main Service Entrance Panel.
A typical low voltage wiring diagram for the Condensing Energy Manager is shown in the Drawings-Wiring section.
Thermostats should be located on inside walls away from cold drafts, windows, heat from fireplaces, appliances or sunlight.
Set thermostat heat anticipators to 0.1 amps or for
Hydronic system to operate properly. Set heat anticipator to greater
than 0.1 amps if a longer cycle is desired.
Call Energy Kinetics to request alternate low voltage wiring diagrams to handle special situations such as heat pump
wiring, isolation relays for thermostats, and isolation relays for heat motor zone valves or circulators, etc. The Condensing
Energy Manager is designed to be compatible with power stealing thermostats.
The Condensing Energy Manager is designed to operate up to five zones. A typical installation will have one hot water
zone and up to four heating zones. Use Energy Kinetics supplied full port zone valves with two wire connections or other
full port two wire zone valves. Use full port, four wire zone valves with end switches for air handler zones, and wire the end
switches to turn on the air handler fan motor.
INSTALLATIONS WITH MORE THAN FIVE ZONES
When the total number of zones exceeds five, an Accel CS boiler with a 12 zone condensing manager is available.
For existing jobs where an Accel CS boiler with a 5 zone condensing manager is already installed, an Energy Kinetics
ERC (Energy Recovery Control) should be added. How to pipe and wire the ERC is shown in the drawing section of the
manual, refer to drawings SYS-05-304 or SYS-05-305.
CONDENSING ENERGY MANAGER OPERATION
Energy recovery is based on time or temperature:
The Condensing Energy Manager will end energy recovery by stopping thermal purge to the last zone that called when
the boiler has cooled off sufficiently. The Condensing Energy Manager also tracks the thermal purge time and will end
thermal purge after a maximum time limit. The DHW zone is limited to a maximum of five minutes. The four heating zones
are limited to a maximum of twenty minutes. Zone 4 has an option to lower the maximum thermal purge time from twenty
minutes to five minutes by turning on option switch 8.
Auto Express or Custom Settings
Select your boiler supply temperature settings using either Auto Express or Custom settings. Auto Express will set the
boiler outdoor reset supply temperatures automatically to either a low range or a high range. The installer will select either
the low range or the high range using a dip switch on the Condensing Energy Manager. Auto Express will set the boiler
supply temperature to a fixed setting every time there is a domestic hot water thermostat call. Custom settings gives the
installer full control over the selection of the outdoor reset settings and of the boiler supply temperature setting used during
domestic hot water heating. The installer selects Custom settings by turning on dip switch 4 and enters the maximum boiler
supply setting and the minimum boiler supply setting for the desired outdoor reset temperatures. Note: setting of the
maximum and minimum boiler supply temperatures can be done only when a domestic hot water call is not present.
Custom settings are all entered by using the Sola display.
