12.3 Change the Domestic Hot Water Comfort Mode Setting
Comfort mode is a domestic hot water setting that enables the boiler to fire up more often to maintain the heat
exchanger temperature. This enables quicker delivery of hot water to hot water fixtures.
By default, comfort mode is disabled (turned off). To enable (turn on) comfort mode, follow the steps below.
Comfort mode has three options:
Option 1: Always Active
This option provides continuous hot water all day long. The boiler maintains the primary heat exchanger
temperature to quickly deliver hot water to the plate heat exchanger. This selection provides the quickest delivery of
hot water to hot water fixtures, but uses the most energy (COMFORT mode will be displayed on the home screen).
Option 2: Time Based
The boiler maintains the primary heat exchanger temperature based on the time selections. This selection requires
more energy use than when disabled, but not as much energy use as the “Always Active” option (COMFORT or
ECO with a time clock logo will be displayed on the home screen depending which mode it is in).
Option 3: Disabled
The boiler operates and produces hot water; however, it will not maintain the primary heat exchanger temperature
for quicker hot water production. This selection saves some energy, but requires longer time to provide hot water to
the hot water fixtures (ECO mode will be displayed on the home screen).
