SAFETY INFORMATION
It is the responsibility of the installer to ensure the installation complies with all national and
local building codes and standards, in addition to the instructions outlined in this manual. All
applicable codes take precedence over any instructions made in this document.
This symbol indicates safety alerts. When you see this symbol on labels or in this
manual, be alert to the potential for personal injury. Understand and pay
particular attention to the signal words DANGER, WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which if not avoided, will result
in death or serious injury.
WARNING indicates a potentially hazardous situation, which if not avoided, could
result in death or serious injury.
CAUTION indicates a potentially hazardous situation, which if not avoided, may result
in minor or moderate injury. It is also used to alert against unsafe practices and
hazards involving only property damage.
WARNING - Improper installation may create a condition where the operation of
the product could cause personal injury or property damage. Only a qualified
contractor, installer or service agency should install this product. Improper
installation, adjustment, alteration, service or maintenance can cause injury or
property damage. Refer to this manual for assistance.
CAUTION - This product must be installed in strict compliance with the installation
instructions and any applicable local, state, and national codes including, but not
limited to; building, electrical, and mechanical codes.
WARNING - FIRE OR ELECTRICAL HAZARD. Failure to follow the safety warnings
exactly could result in serious injury, death, or property damage. A fire or electrical
hazard may result causing property damage, personal injury or loss of life.
WARNING - Hot water from a boiler used to satisfy heating requirements can be
heated to temperatures of 180°F. Parts containing water this hot can scald very
quickly. Use extreme caution when servicing or performing maintenance on any
parts containing hot water. To avoid severe burns, allow equipment to cool before
performing maintenance.

INTRODUCTION
The ecosmart hydronic furnace is designed to maximize performance and comfort in residential
or light commercial applications. The ecosmart can be used with a variety of heat sources such
as boilers and water heaters and can be implemented in combo systems that provide domestic
hot water as well as space heating.
Smart control systems within the ecosmart allow extraction of maximum heat by allowing
condensing high efficiency heat sources to work at their maximum efficiency while providing
ultimate comfort with unmatched performance.
Simple, independent heat/cool and system parameters can easily be set by the installer to
adjust for a wide variety of installations. Various parameters are automatically monitored and
fan and pump speeds vary simultaneously. The ecosmart has a built-in variable speed pump
controller that can vary the speed of a standard single speed AC pump.
MODES OF OPERATION
Three modes of operation are available:
1. Full modulation – full control of fan and pump (requires outdoor temperature sensor).
2. Step modulation – timed fan and pump sequencing.
3. Single stage – standard furnace emulation.
Modulating Mode
(ecosmart outdoor sensor installed)
Water temperature is set at the heat generator by referring to the heat generator performance
data. It is best to maintain constant water temperature at the heat generator.
If the heat generator comes with an optional outdoor temperature sensor do not
install it as it will conflict with the ecosmart control.
5 | P a g e
The fan operates at the speed selected on the HEAT CFM switch during the setup. Fan and
pump speed automatically reduce as outdoor temperature rises. Fan CFM may reduce by up to
30% from the HEAT CFM switch setting depending on outdoor temperature.
If the heat generator includes a built-in pump, and it is directly connected to the ecosmart, the
ecosmart will vary the pump automatically. If the system is configured for primary/secondary
pumping and the heat generator includes a pump, the secondary pump can be controlled by
the ecosmart.
Step Modulating Mode
(ecosmart outdoor sensor not installed)
Water temperature is set at the heat generator by referring to the heat generator performance data.
Fan operates at 50% of the HEAT CFM setting for 5 minutes then increases to 75% for a further 5
minutes, then increases to 100% until the thermostat is satisfied. If the pump is controlled by the
ecosmart, its speed will be adjusted accordingly as the ecosmart goes through its stages. If the pump is
controlled by the heat source, it will function according to the heat source control strategy.
Basic Mode
(ecosmart outdoor sensor not installed)
Water temperature is set at the heat generator by referring to the heat generator performance
data. Fan operates at 100% of selected HEAT CFM and pump operates at maximum speed until
the thermostat is satisfied.
