Ventilation and building systems
Controls for ventilation and building-management systems.
Custom control systems for projects large and small
Our team has years of experience in control systems. Using Siemens PLCs and mySCADA HMI systems, we handle design, control drawings, programming and commissioning.
Our solutions
We design controls for buildings, utilities and industry, and can bring several systems together in one HMI for a shared overview.
Utilities
Control and monitoring for pumping stations and utility networks.
Industry and production
Controls for production and process equipment.
Fire-damper systems
Fire-damper control, status monitoring and automatic testing.
Pool & hot-tub systems
Temperature, circulation and chemical dosing controls for swimming pools and hot tubs.
Building and lighting controls
Controls for lighting, underfloor heating and blinds. We use KNX for building controls, including lighting, and DALI for lighting control.
Example: School Example: Colour-controlled outdoor lighting and snow melting
An overview of your operation
Real-time monitoring
The state of the whole system in one place, updated in real time.
Alarms
Alarms and event logging when operating conditions fall outside set limits. An alarm can also reach whoever is on call by phone call, SMS or email.
Trends & reports
Recorded measurements, trends and reporting with myREPORTS.
Remote access
Monitor the system securely through a browser on your computer, phone or tablet.
Control system essentials
How a control system works
The PLC reads sensor measurements and controls the equipment. The HMI displays system status and lets you monitor operation and adjust settings. The PLC keeps controlling even when the HMI is not connected.

The blue labels show AndOr's part in each layer.
- The level rises
The level sensor measures the level in the well and sends the measurement to the PLC.
- Pump started and stopped
The PLC starts the pump at the start level and stops it at the stop level. The levels are set in the HMI, which shows the level and the pump status.
- Alarm
In heavy inflow the level keeps rising although the pump is running. Above the alarm level an alarm shows in the HMI until the level is back within limits.

We also provide support after handover, whether settings need adjusting or equipment needs adding.
