TANKLESS DOMESTIC HOT WATER MODES
Tankless Domestic Hot Water - Standard, Comfort, and
ECO Comfort Modes
Standard Mode (OFF):
The unit’s heat exchanger will not maintain its domestic
hot water temperature between demands for hot water. The unit will respond
to a call for domestic hot water as a priority over the space heating demand.
When the domestic hot water demand is satisfi ed the unit will return to the space
heating load if the load is still calling.
Comfort Mode (ON):
The unit’s heat exchanger is maintained at the DHW
temperature.
ECO Comfort Mode (ECO):
This mode operates like the comfort mode but has
the added advantage of learning when the domestic hot water is used. During the
low use periods, the heat exchanger is allowed to cool.
To switch between the 3 modes:
1. Touch the area above the white dot.
2. Touch the Tap button twice.
3. Touch the Plus or Minus buttons.
NOTE
The domestic hot water
thermostat is adjusted to its
lowest temperature position
when shipped from the
factory. It’s recommended to
set the domestic hot water
thermostat to 120°F/49°C as
an initial setting and further
adjust as required. For
energy effi cient operation,
this setting should be set
as low as practical for the
consumer’s needs.
NOTE
The unit is equipped with
a Frost Protection feature.
This feature will operate the
unit’s burner to help protect
the unit from freezing. IBC is
not responsible for damages
to the unit, and/or related
components, nor property
damages that may result from
freezing conditions.
