is especially the case in retrofit applications where a much larger pump may have previously
been used in the system.
The ecosmart includes a built-in variable speed pump controller that can control a standard
single speed pump up to 250 watts. Operational modes are as follows:
• When set up in modulating mode, the pump will operate as a continuously variable
speed pump
• When set up in step-modulating mode, the pump will operate as a multi-speed pump.
• When set up in basic mode, the pump will operate as a single-speed pump
• The ecosmart controller has a built-in pump timer that exercises the pump for 1 minute
every 24 hours to prevent the possibility of ‘sticking’ due to sediment and local codes
Water Heater or Boiler Setup
Follow the manufacturer’s installation and start-up instructions of the water heater or boiler.
Make sure the equipment is turned off during installation and service. Make certain the
equipment has been refilled and all air is purged from the system before turning on the heater.
WARNING - When the system requires water temperatures higher than 120F,
a mixing valve shall be installed to reduce domestic hot water temperature to
safeguard against scalding.
Combo Systems
The ecosmart is ideal for use in combo systems which provide space heating and domestic hot
water from a single heat source. Any properly sized gas, propane or oil fired water heater or
boiler will work in a combo system. Make sure any water heater being used is approved for
combo applications.
