NETWORK CONFIGURATION
Using the following parameters, it is possible to configure the ECC III network to accommodate a wide variety of
installation options. Press the I key to access these parameters on the configuration menu. These parameters must be set
in each unit individually. Default values are shown in bold type.
Network Ctl - No (Yes or No)
Determines whether the unit will participate in the master/slave environment. Setting this parameter to
No
will cause
the unit to act like a standard single ECC III unit. This unit will never become the master on the network and will not
listen to the control variables broadcast by the master. Although units with this parameter set to
No
do not participate
in the master/slave environment, they are still accessible through any network RIU. Like
Local
pool water control, this
parameter, when set to
No
, requires this unit to be displayed on the RIU before changing any of the set points.
Water Temp Ctl - Local (Local or Net)
Determines whether the unit will control water temperature based on the master’s command (Net) or its own
temperature sensor(s) and set points ( Local ). If a unit set to Local becomes the master, other units in the network will
not use the master’s command for water heating. Instead, they will look at the next unit in line that is not set to Local .
This parameter is set to Local only if the unit is connected to a different pool than the rest of the units on the network.
Because the unit is controlling water temperature on its own, it is necessary to select the correct unit with the RIU before
changing the water temperature set point.
CHANGING NETWORK SET POINTS
Each unit on the network maintains two groups of set points: network and local. If a unit has the Network Ctl parameter
set to Yes and the Water Temp Ctl parameter set to Net, it will control to the network set points. Set points changed when
the RIU is displaying this unit will be changed in every unit on the network with the same Network Ctl and Water Temp
Ctl parameters. Units that are configured for Network Ctl and Local Water Temp Ctl will use the local water temperature,
set point and the network air temperature and relative humidity set points. The water temperature set point will only be
changed in the unit currently being displayed by the RIU. Units that are not configured for Network Control will use all
local set points. Therefore, any set points changed while the control panel is displaying this unit will be changed only in
this unit.
