BOILER MODEL
Check the
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.
HIGH ALTITUDE
If the boiler is installed at an altitude above 5,500 feet, select
YES for high altitude.
firing rates (blower speeds) to compensate for altitude.
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 tem-
porary setting for test purposes ONLY.
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.
ADJUST OUTDOOR
1. Use this setting to adjust the outdoor sensor tem-
perature to account for solar or other effects, such
as long lead wire, that would cause the sensor to
read incorrectly.
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)
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.)
