3.1 Cooling

In cooling mode: the refrigerant is condensed in the outdoor unit and evaporated in
the indoor unit. Via the heat exchange with water in the indoor unit, the temperature of
water decreases and it releases heat while the refrigerant absorbs heat and
evaporates. With the help of wired controller, the outflow temperature can meet the
user's requirement. Through the control of valve, the low-temperature water in the
system is connected with indoor fan coil and underground pipe, and exchanges heat
with the indoor air so that the indoor temperature decreases to the required range.

3.2 Heating

In heating mode: the refrigerant evaporates in the outdoor unit and is condensed in
the indoor unit. Via the heat exchange with water in the indoor unit, the water absorbs
heat and its temperature increases while the refrigerant releases heat and is
condensed. With the help of wired controller, the outflow temperature can meet the
user's requirement. Through the control of valve, the high-temperature water in the
system is connected with indoor fan coil and underground pipe, and exchanges heat
with the indoor air so that the indoor temperature increases to the required range;

3.3 Water Heating

In water heating mode: the refrigerant evaporates in the outdoor unit and is
condensed in the indoor unit. Via the heat exchange with water in the indoor unit, the
water absorbs heat and its temperature increases while the refrigerant releases heat
and is condensed. With the help of wired controller, the outflow temperature can meet
the user's requirement. Through the control of valve, the high-temperature water in the
system is connected with the coil pipe of bearing water tank, and exchanges heat with
the water in the water tank so that the temperature of water tank increases to the
required range；

3.4 Cooling +Water Heating

When cooling mode exists together with the water heating mode, the user can set the
priority of these two modes based on the needs. The default priority is heat pump. That
is under the default setting, if cooling mode exists together with the water heating mode,
