Connection

How to Connect to 6S Teknoloji

Physical Connection

Connect the device to the RS-485 or Ethernet network. Configure Slave ID and baud rate from the device front panel or web interface.

Add Device in 6S Teknoloji

From the 6S web panel click "New Device". Select York YVAA from the template list — the register map loads automatically.

Live Monitoring

The Field Agent tests the connection; the first readings appear on the dashboard shortly. Alarm thresholds are configured.

Monitored Metrics

What Can You Monitor?

FAQ

Frequently Asked Questions

How does the York YVAA connect to 6S Teknoloji?

The YVAA control panel offers Modbus TCP communication; the chiller connects to the Field Agent over the existing LAN. Selecting the York YVAA template in 6S Teknoloji loads the parameter map automatically — a field-proven, ready template.

Can the setpoint be changed remotely?

Yes. The chilled water setpoint can be written from 6S Teknoloji with a signed, authorized command; only the defined safe range is accepted and every change is recorded in the audit trail.

Which alarms are monitored?

Fault codes produced by the YVAA are read instantly and fed to the alarm engine: code changes, compressor stops and abnormal pressure conditions generate email/panel notifications. Alarm history is stored with timestamps.

Is the chiller's electricity consumption also visible?

Yes. The energy analyzer in the chiller's supply panel is paired with YVAA telemetry; kW draw, daily kWh and load percentage are tracked on the same chart, so efficiency drift is noticed early.
