BOILER MODEL
Check the boiler model
boiler's rating plate. Change the selection to the correct model
if not. Also verify the model number on the ECO control
display at power-up. Failure to correct could result in severe
personal injury, death or substantial property damage.
The 110 model can either be a 110HW or a 110EBM. Earlier
models of the 110 (Series 1) boilers used a Honeywell blower
and are denoted as 110HW in the Boiler Model selection.
The 110 (Series 2) model uses an EBM blower and is denoted
as a 110EBM in the Boiler Model selection. This boiler manual
is for the 110 (Series 2) model. For older version of the 110
(Series 1) model, please reference the correct boiler manual.
HIGH ALTITUDE
If the boiler is installed at an altitude above 5,500 feet, select
YES for high altitude. Selecting YES will automatically adjust
firing rates (blower speeds) to compensate for altitude.
ODT SENSOR EXEMPT
1. This setting is used to determine if the boiler should operate with and
continually detect an outdoor temperature.
2. All boilers must comply with the regulations shown on page 127.
3. If the boiler formerly used an ODT sensor but now has become exempt,
contractor may change settings here.
HIGH LIMIT TEMPERATURE
The boiler's high limit temperature during normal operation
is fixed at 200°F and cannot be changed. The HIGH LIMIT
TEMPERATURE setting in the ECO control menu is a
temporary setting for test purposes ONLY.

— Boiler Manual
1. If boiler outlet water temperature exceeds this
temperature, the ECO control will shut down the
boiler and enter lockout. Manual reset is required
to restart the boiler.
2. The HIGH LIMIT TEMPERATURE setting will
automatically return to 200°F if power is turned
off. The boiler will restart when power is restored.
3. Use this control setting only to test the control's
high limit function.
WWSD
1. WWSD stands for "warm weather shutdown." It
means the boiler will not be allowed to fire if the
outside temperature is greater than the WWSD
setting.
2. When the boiler is kept off because the outside
temperature is above WWSD, the graphic display
will show "WWSD," and the boiler will remain in
standby until the outside temperature drops below
WWSD temperature.
3. WWSD does not apply to DHW systems.
4. The outdoor sensor must be installed to use this
function.
The outdoor sensor must be installed
unless specifically exempted in the Energy Act
statement on page 127.
ADJUST OUTDOOR
1. Use this setting to adjust the outdoor sensor
temperature to account for solar or other effects,
such as long lead wire, that would cause the sensor
to read incorrectly.
Comment
THIS MUST BE SET CORRECTLY FOR SAFE
OPERATION. Adjusts blower speeds and flame
sense (Startup screen will show "HA" after the model number if
high altitude has been selected, below.)
Adjusts ignition and low fire fan speed (for altitudes above 5,500
feet only).
Used to determine if boiler should operate with and continually
detect an outdoor temperature.
If boiler out temperature reaches this temperature, boiler will
lockout, which requires a manual reset.
Boiler will not respond to heating calls above this outdoor temp.
This value plus outdoor sensor reading equals outdoor temp
(Use this setting to compensate for solar gain or other factors
that cause a shift in sensor temperature.)
