ZONE DEPENDING
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.

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".

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:
