The hydro module features the heating function and DHW function, which can be classified into the hydro module that supports
heat mode only (''FOR SERVICEMAN'' > ''Heat mode setting'' > ''HEAT MODE=YES'' and ''FOR SERVICEMAN'' > ''DHW mode
setting'' > ''DHW MODE=NON''), the hydro module that supports DHW mode only (FOR SERVICEMAN'' > ''Heat mode setting''
> ''HEAT MODE=NON'' and ''FOR SERVICEMAN'' > ''DHW mode setting'' > ''DHW MODE=YES''), and the hydro module that
supports both heat mode and DHW mode (''FOR SERVICEMAN'' > ''Heat mode setting'' > ''HEAT MODE=YES'' and ''FOR
SERVICEMAN'' > ''DHW mode setting'' > ''DHW MODE=YES''). The heat mode is classified into leaving water temperature
control (''FOR SERVICEMAN'' > ''Heat mode setting'' > ''LEAVING WATER TEMP.=YES'') and room temperature control (''FOR
SERVICEMAN'' > ''Heat mode setting'' > ''ROOM TEMP.=YES''). The leaving water temperature control and room temperature
control is either-or. In leaving water temperature control mode, the hydro module sets the desired leaving water temperature
and operates according to the defined desired temperature. In room temperature control mode, the hydro module sets the
desired room temperature and conducts control according to the room temperature collected by the wired controller.
The wired controller interfaces are subject to on-site settings. Definitions of symbols of the wired controller:
ROOM---Room temperature control
MAIN---Leaving water temperature control
DHW--- Domestic hot water mode
Scenario 1
Only heating mode is available and the hydro module is operating in leaving water temperature control mode. (For more
information, please read the Installation Manual.)
