2 Overview
2.1 Connections and functions
The following block circuit diagram shows the SEZ220 connections and function
blocks. The function blocks convert the signals to the inputs as per the
configuration and parameterization, and provide them via the outputs as
DC 0…10 V signals.

You may only use Synco™ 200 products to control and monitor heating, ventilating,
air conditioning, and chilled water plants.
Field of use
Safe and trouble-free operation of Synco™ 200 products presupposes transport,
storage, mounting, installation and commissioning as intended as well as careful
operation.
Intended use
Fuses, switches, wiring and earthing must comply with relevant national safety
regulations for electrical installations.
Electrical installation
Only qualified staff trained by Siemens Building Technologies may prepare and
commission Synco™ 200 products.
Commissioning
Only persons trained by Siemens Building Technologies or their representatives
who are properly informed of the risks may operate Synco™ 200 products.
Operation
When wiring, strictly separate AC 230 V mains voltage from AC 24 V safety extra-
low voltage (SELV) to protect against electrical shock!
Wiring
Refer to the environmental conditions specified in the respective data sheets for
storage and transport.
Storage and transport
Contact your supplier or Siemens Building Technologies if you have any questions.
Synco™ 200 products are maintenance-free and require only cleaning at regular
intervals. We recommend removing dust and dirt from system components
installed in the control panels during standard service.
Maintenance
Call service staff responsible for your plant in case of system faults; do not
diagnose and correct faults.
Faults
Only authorized staff may diagnose and correct faults and recommission the plant.
This applies to working within the panel as well (e.g. testing or changing fuses).

4 Commissioning
4.1 Safety
Only qualified staff trained by Siemens Building Technologies may prepare
and commission the SEZ220 signal converter.
4.2 Begin commissioning
4.2.1 Initial startup
The commissioning menu automatically starts when AC 24 V operating voltage is
supplied to the signal converter. Note:
Procedure
During commissioning, the application is not active. The outputs are in a defined
OFF state.
The following settings are displayed as soon as the signal converter is started:
Basic settings
•Access level PASS (Password level).
•COMMIS (Commissioning) menu with flashing menu item PARA (Settings).

4.3 Select basic configuration
4.3.1 Select basic type
First, enter the basic type in the unit. Selecting the basic type via menu APPL ID
(Basic configuration) enables or disables functions. The SEZ220 provides the
following basic types:
APPL ID menu
•M Empty configuration.
•Mxx Applications with MIN-MAX-AVR functions.
•Exx Applications with ENTHALPY function.
•Dxx Applications with 2X-INV function.
4.3.2 Select programmed application
The unit contains tested, programmed applications. They are described in data
sheet CE1N5146en.
Selection
The easiest way to commission the unit is to activate one of these programmed
applications and to adapt the configuration as needed.
Select the application via COMMIS > APPL ID,
and confirm with OK.
Line APPL ID displays: M01
Selection example
This means:
M Standard application, basic type M.
01 First number of this basic type.
The INFO menu contains data pointAPPL ID: It provides information on:

4.5 Three ways to select the right application
4.5.1 Programmed application
The easiest way to commission the unit is to activate a programmed application
and adapt the configuration to the requirements of the relevant plant.
Data sheet CE1N5146en describes the programmed applications.
4.5.2 Adapted application
The programmed application is not quite right, but data sheet CE1N5146en
describes an adapted application.
In this case, enter your adaptations via the CONF (E ) menu.xtra configuration
Press OK to save the settings.
4.5.3 Free configuration
The desired application is not described and the configuration must be created
from scratch: This includes the following:
•Complete the configuration diagram for the desired application (see chapter 10).
•Configure the unit by selecting basic type M (MIN-MAX-AVR).
You can cancel or recreate an existing free configuration or parts thereof any time
by selecting and confirming basic type M.
4.6 Wiring test
When peripheral devices are connected, test the wiring via the TEST (wiring test)
menu. We recommend testing after configuration and settings are complete. The
test provides the following functions:
•Display reading values for inputs.
•Display reading values for outputs.
The application is not active during the wiring test. The outputs are in a defined
OFF state.
During wiring test, both inputs and outputs are checked for the following errors:
•Connection error (mixed up wires).
•Position error (mixed up sensors or actuating devices).
•Discrepancy between connections and configuration (e.g. LG-Ni 1000 in place of
active DC 0...10 V).
