5.1

Zone control with Depending module

The thermal elements Depending on the Steel Pro Power are
prepared as standard to be configured as zones.
Thus, for example, a thermal module with 4 thermal elements
will be set up as standard for the management of 3 zones (one
for each Second thermal element) installed inside the thermal
module itself.
To enable the functioning of the element as a zone, the proce-
dure described below must be carried out.

Setting zone parameters (accessible only with installer password)

Menu → "Settings" → "Config. area dep "
This menu allows you to separately set the parameters of all the connected zones with the exception of the "Extra setpoint zone"
which is the same for all zones.
To select the zone for controlling/changing the parameters, proceed as follows:
− press the ► button so that the number to the right of the word "zona dep." is highlighted;
− once the number is highlighted use the ▲ and ▼ keys to change the number of the zone;
− once the zone is selected, confirm with the ● key.
The zone parameters are the following:
Standard value that
Description
is set
Mix Valve Max Op/Cl Time 25
PID P Zone 10
PID I Zone 150
PID D Zone 0
Extra zone setpoint 10
The setting of the parameters of the climatic curve and the programming of the dependent zone is identical to that of the additional
external zone, as described in the paragraphs "Setting zone's climatic curve parameters (accessible only with installer password)"
and "Programming the zone".
Access the following menu:
Home/Menu Config. (97) Appliance
Settings DEP n°
screen dispositivo Configuration
− Choose 19 (pump versions) or 18 (valve versions)
− Select "CONFIRMED CONFIG"
− Select "YES"
− Wait for initialization and finalization.
The (temporary) error appears on the initial screen 164 and then
the error 208 that signals that the zone probe is not connected.
At this point the zone is ready to be connected as reported in the
paragraph "Typical water system schematics".

Deleting dependent zone

To remove a Dependent zone operate in the reverse way to its
installation:
− enter the parameters menu and select the par. 205.
Change its value from "Enabled" to "Disabled";
− change the par. 97. If par. 97 = 19 change to = 16; if par. 97
= 18 change to = 17.
On the "Information" menu:
− enter "Status zone dep.";
− select the number of the depending zone;
− The "Detection" field will indicate "NO";
− select "Remove zone" changing to "YES" and confirm.
Now in the "Settings" and "Information" menus the depending
zone will no longer be displayed.
The electronic control of the thermal module will automatically
check which zones are connected to the bus.
The menu items of the zone in the electronic control of the ther-
mal module will be available when one or more zone manage-
ment devices are detected.
The electronic control of the thermal module remembers the
zone number detected when a device is connected.
The zone number detected is not automatically removed when
the corresponding accessory is no longer connected.
The zone number needs to be removed manually.

Removing the zone number
− remove the bus connection of the zone to be deleted;
− access the Settings/Zone Config./Zone;

− go to Remove Zone;
− press the ► key to highlight the values, change them to
"Yes" with the ▲ / ▼ keys, press the ● key to confirm and
remove the zone from the display menus.
