IT Technology Project

As a Junior Software Developer, I contributed to a team responsible for developing the 'IHS Control System,' a specialized application designed for managing heating and domestic hot water systems.

Protocol Simulation

The IHS Control System is a desktop-based graphical application designed to simulate and control district heating and domestic hot water (DHW) subsystems. The software replicates all key operational and diagnostic aspects of a physical IHS (Individual Heating Substation), and allows the users to interact with a virtual system that mimics real-time performance. The software interface consists of two main areas: A left-hand sidebar that provides navigation to all major pages. A main content area that changes based on the selected page

TCP/IP Simulation

Shows HTMS protocol packet flow
Each row shows timestamp, command type, and value (e.g., temperature read/write)
Click "Export to CSV" for offline inspection

Modbus Simulation

Displays a list of simulated registers with address, parameter name, and value. Data types and access (Read-only or Read/Write) are indicated.

Maintenance Tip

Use this page to simulate and verify communication with SCADA or third-party integrations. For debugging, export logs after any error to document packet flow.

Domestic Hot Water System

DHW Temperature Setpoint and Control System for district heating management.

DHW Temperature Setpoint

Adjust using the slider (40–70°C). The default is 55°C
Below, the current measured temperature is displayed

Inlet/Outlet Temperature Cards

Show temperatures at critical DHW points: Cold inlet (5°C), Hot outlet (53°C)
Supply and Return from exchanger

Water Quality Indicators

Automatically assesses Iron content, Oxygen level, and Suspended particles
Status labels (Normal, High, Warning) are color-coded for quick evaluation

Recirculation Pump

Shows pump status and last activation time
Can be manually overridden if needed (checkbox)

Water Usage Panel

Real-time flow rate in m³/h
Accumulated usage (m³) for billing or efficiency review

Maintenance Tip

If the outlet temperature frequently dips below the setpoint, increase the DHW supply temp or inspect for flow inconsistencies. High oxygen levels in quality indicators suggest pipe corrosion risk.

Real Time Monitoring

This section controls and monitors the DHW side of the IHS.

Heating System Control

Real-time Monitoring with interactive, zoomable charts that update each minute.

District Heating Circuit (Primary Side)

Shows supply/return temps from central district supply

Building Heating Circuit (Secondary Side)

Shows building loop temps

DHW Circuit

Tracks DHW supply, return, and outlet temperatures

Temperature Differentials

Delta T values showing system efficiency

Chart Analysis

Each graph helps visualize temperature trends
Can assist in diagnosing delays, imbalance, or misconfigurations

Maintenance Tip

Look for consistent ΔT (Differential Temperature) behavior. Anomalies like sudden spikes or drops may indicate sensor failure or controller misreadings.
