Setting Comfort and Eco Domestic Hot Water Setpoints
The Comfort and Eco Domestic Hot Water Setpoints are programmed in the Setup Menu. For
details on Domestic Hot Water Operation, see section 4.4 of the Control Manual OMM-0159.
The Ufly screen automatically turns off after 20 seconds (default) of inactivity. If the "Always on"
is toggled on like in the image below, the screen will remain on all the time.
NOTE:
Do not change the value of the Modbus address. This is an internal function of the
boiler. For Modbus setup when communicating to AERCO ACS or BAS/EMS, see section 6.8 of
