Scenario 6
Group control of the hydro module.
When multiple hydro modules heat water in one water tank, the group control function of the hydro module should be used. (For
more information, please read the Installation Manual.) The group control function is only valid for the DHW mode.
Notes:
1. The group control function of the hydro module is valid for the DHW mode only.
2. Master and slave hydro modules should be set. For instructions on how to set master and slave hydro modules, see the
Installation Manual.
3. The master hydro module must be connected to a wired controller. The main wired controller can be used to set temperature.
4. The slave hydro module can be connected to or not connected to a wired controller. The slave wired controller provides
limited functions, such as parameter query.
5. The circulating pump and water tank temperature sensor should be connected to the master hydromodule.

To enable the group control function, you need to set
the DIP switch on the main board as follows: for the
master hydro module, turn digit 11; for the slave
hydro module, turn digit 10:
Group control function setting:
00 and 01: Group control function is
unavailable.
11: Group control function is
available. This hydro module is a
master hydro module.
10: Group control function is
available. This hydro module is a
slave hydro module.
(By default, the value is 00,
indicating that a controlled group
contains only one master unit.)
ON=1,OFF=0
Notes:
1. The master unit must be connected to a wired
controller. The wired controller is used to set the
desired water tank temperature.
2. The slave unit can be connected to or not
connected to a wired controller. The wired controller
of the slave unit provides the query function only.
3. The pump is controlled by the master unit. The
temperature sensor of the water tank is connected
to the master unit.
4. The wired controller connected to the master unit
is used to set the desired water tank temperature.
