2.4 TANKLESS DOMESTIC HOT WATER
MODES
2.4.1 Tankless Domestic Hot Water - Standard and
ECO Comfort Modes
Standard Mode (OFF): 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 satisfied the unit will return to the space heating load if the load is still calling.
The water heater’s heat exchanger will not maintain its domestic hot water
temperature between demands for hot water.
Comfort Mode (ON): The water heater’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.
