12. Pump cycling for combination space and domestic hot water

heating systems (“FE”)

As building enclosures become more energy efficient and heating loads are small, a single hot

water heater can often supply hot water for both domestic use and space heating. This type of

heating system is especially popular in multi-family housing. For such systems, this option can

be turned ON to avoid potential microbial buildup in the space heating plumbing loop during

periods of inactivity. This feature assures that the heating circulator operates for at least one

minute out of every 24 hours.

a. Press the Select button until “FE” appears on display.

b. Using the “+” and “-“ buttons adjust the pump status – select

ON or OFF.

ON causes the circulator pump (W terminal) to be energized

for 1 minute if it has not been energized for 24 hours.

Default - OFF

c. Press the Select button again to return to normal display

mode.
