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.
Simple, independent heat/cool and system parameters can easily be set by the installer to adjust for a wide variety of installations. The ecosmart features a 5-speed high efficiency EC fan motor and a pump control which can operate a standard 120VAC pump or a variable speed pump from the 0-10V interface that provides LO/MED/HI functionality.

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.
The ecosmart can be installed in upflow, downflow 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 downflow applications so that the top of the unit is now the bottom. No modification is required for any configuration.
Follow recommendations supplied by the manufacturer of the heating source being used. ecosmart includes a flow switch connection where a flow switch can be connected to allow for domestic water priority. Note: the correct type of flow switch is a normally open (NO) device.
A drain pan is recommended underneath the appliance for all installations. 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.
boiler will work in a combo system. Make sure any water heater being used is approved for combo applications. PIPING DIAGRAMS Tankless Water Heater Piping 13 | P a g e...
Electrical Information The ecosmart wiring diagram is located on the cover of the electrical box behind the lower front panel. Ratings data is located on the lower front panel. The ecosmart operates on 120VAC 60Hz single phase line voltage and should have its own dedicated breaker or fuse rated as per the MOP on the ratings label ...

Miscellaneous wiring to the upper right tabs of control board as marked: FLOW – connect a normally open (NO) flow switch. If there is a call for DHW, fan will shut down and resume once the call for DHW has ended ...
DIP SWITCH OPTIONS Switch Locations Two DIP switches labelled CFM and OPTIONS are located on the top left section of the control board. One switch is for Heat and Cool CFM rates, and the other for system options. WARNING – to prevent damage, use a small screwdriver to change switch position. Up is ON as marked on the switch body and each switch is identified with numbers below.
Dehumidification Fan Cooling (3) Not used Not used (2) ES90LVS runs at 400 CFM, ES50LVS runs at 300 CFM. (3) Fan Cooling runs at lower COOL CFM rate for 15 min. and then goes to higher rate. SEQUENCE OF OPERATION...

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 ...
Thermostat call error If the ecosmart does not run when the thermostat is calling, 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 to prevent compressor damage.
