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.
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.
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.

Set the design water temperature to deliver the necessary amount of BTUs to the air handler. 5. Once all air has been purged, turn on the power to the ecosmart and set the room thermostat to heat and set the temperature high enough to initiate a call for heat. This will energize the air handler an in turn the fan and pump.
It is not recommended to install the ecosmart in an unheated space. Should the ecosmart be installed in an area where the ambient temperature may fall below freezing, ethylene or propylene glycol should be added into the hydronic heating system to protect against damage, which would not be covered under warranty.
The ecosmart can be installed in up flow, down flow and left or right horizontal applications. Install the ecosmart with the door in place to make sure the cabinet remains square. Flip the unit for down flow applications so that the top of the unit is now the bottom. No modification is required for any configuration.
Pump A pump is not included inside the ecosmart. Whether you are using an external pump or an internal built-in pump, it should be sized for the system. Pumps supplied with the heat generating units can be used as the sole pump provided it meets the needs of the system. This is especially the case in retrofit applications where a much larger pump may have previously been used in the system.

LVP Main Wiring Information When using a water heater and domestic hot water (DHW) priority is required, connect a normally open (NO) flow switch. If there is a call FLOW for DHW, fan and pump will shut down after 1 minute.
LVP Miscellaneous Wiring Output for variable speed pump control. Provides: 0-10V or PWM output. VARIABLE PUMP Connect between COM and PWM for PWM output. (ADDITIONAL CONTROL INTERFACE) Connect between COM and 0-10V for variable voltage output. Active when heating. PUMP RELAY 24VAC power to activate relay for standard 120VAC pump.
LVP Indicator Lights Lights when fan activity signal is present. Intensity varies with fan speed. POWER Lights when 24VAC power is present. PUMP Lights when pump is on. HEAT Lights when heating. COOL Lights when cooling. DIP SWITCH OPTIONS Switch Locations Four DIP switches are located on the top, mid-section of the control board.
(2) Normal Fan Cooling runs at rate set by COOL CFM switch. Dehumidification Fan Cooling runs at 85% of COOL CFM rate for 10 min. ON EACH COOLING CYCLE and then reverts back to rate set by COOL CFM. (3) Normal Continuous Fan runs at rate set by HEAT CFM switch. Low speed Continuous Fan runs at 50% of rate set by HEAT CFM switch.

40°F or lower the ecosmart will bring on the circulating fan and energize the pump. If in cooling mode, the ecosmart will also turn on the condenser by breaking the C connection.
Pump Exerciser • The circulating pump is exercised for 1 min every 24 hr when the ecosmart is OFF, COOLING (Y), COOLING2 (Y2) or FAN (G) to prevent the possibility of ‘sticking’ due to sediment and to meet local codes.
If the ecosmart does not run when the thermostat is calling, remove the thermostat connections at the ecosmart and jumper R to W for heating, or R to Y (Y2) to verify if the problem is with the thermostat or ecosmart control. Note that some thermostats have a delay (typically five minutes) before they will re-start cooling.
The contactor in the condenser shuts off because it requires more current to stay on. Solution: replace with a modern thermostat which has no heat anticipator.
External pump does not run (sticking issue) In areas where hard water is present the pump may stick and fail to run. Often, closing the isolation valve on the return leg and opening the drain port so that water flows through the pump can free this.
REMOVING BLOWER/CONTROL ASSEMBLY Blower and control assembly can be removed as a single piece: • Turn off power to ecosmart • Disconnect AIR OUT temperature sensor (white plug/socket) just above front centre plate and pull up out of the way to prevent damage to the cable when sliding out assembly •...
