pages 67-78).
MANDATORY CONTROL SETTINGS
— The
following settings must be checked and adjusted
if necessary: BOILER MODEL and HIGH
ALTITUDE in BOILER SETTINGS menu. See
instructions on the following pages for menu
access and control settings.
1.
The
ECO
control is set up to supply one DHW input
and one HEAT input. Circulator outputs are relays
controlled by the boiler control module.
2.
All
ECO
boilers MUST utilize the provided outdoor
temperature sensor for outdoor reset functionality
unless exempt — see page 127.
3. All heating zones use the same temperature settings (or
outdoor reset curve if outdoor sensor is connected — see
page 127).
4. DHW input is priority over the HEAT input.
5. DHW temperature settings are separate from heating settings
and DHW calls do not use the outdoor reset curve.
6. Default heating settings are for finned tube baseboard only.
(Other heat emitter types may require changes in the control
setup.)
7. Only one zone thermostat or end switch input is provided.
Use zone controllers for multiple zone systems.
8. Some of the default boiler and temperature setting are
summarized in Figure 75 below. Verify that these settings are
acceptable for the system type.
9. If the system qualifies for direct connect system piping
(guidelines on page 43), reference the following pages for
piping and control suggestions:
a. General guidelines — pages 43-45.
b. Zoned with zone valves — page 46.
10. If the system is piped using primary/secondary system
piping, reference the following pages for piping and control
suggestions:
a. General guidelines — pages 47-50.
b. Zoned with zone valves — page 51.
c. Zoned with circulators (single temp heating) — page 52.
d. Zoned with circulators (multi-temp heating) — page 53.
Other control settings may need to be adjusted in
order for the control to operate the system most
effectively. To ensure proper operation, read all
instructions on pages 68-78 before starting up
the system. Failure to comply could cause system
problems.
