Controllers

Heating and HVAC controllers

Electronic controllers for automating heating systems and HVAC processes ensure precise control of heat substations, boiler houses and ventilation units. The range features Danfoss and Ouman solutions that meet industry standards, suited both to new projects and to the renovation of building services.

Most popular controller models

In our catalogue you will find widely used electronic controllers suited to systems of varying complexity:

• Danfoss ECL Comfort series: ECL 210 (designed to control up to 2.5 circuits), ECL 296 and the extended-capability ECL 310 models.
• Ouman controllers: the freely programmable Ouflex A, the standard S203, EH-800 and EH-200 models for heating and building automation (BMS) needs.

Heat substation automation: how to choose a controller?

Choosing the right equipment depends on the number of circuits to be controlled, the system type and the need for integration. Pay attention to these technical nuances:

• Sensor standard: Danfoss ECL controllers use the Pt1000 standard. This is a critical factor in renovation - older Ni1000 or NTC sensors will not work with this equipment and must be replaced.
• Actuator compatibility: For serious heating systems and heat substations, controllers are combined with AMV or AME series actuators. For zone manifolds, TWA-Z type actuators are enough.
• Application keys: Keys are grouped by purpose (heating, DHW, ventilation). Important: A3xx series keys suit only ECL 310 controllers, while the A2xx series is compatible with both the ECL 210 and the ECL 310.

Frequently asked questions (FAQ)

Can Danfoss controllers be connected to remote monitoring systems?
Yes, the ECL 296 and ECL 310 models support direct integration with Danfoss ECL Portal and Leanheat Monitor solutions for remote monitoring and control.

What makes Ouman controllers stand out in modern systems?
Ouman models (S203, Ouflex A, EH-800, EH-200) are valued for quick commissioning and flexibility. The Ouflex A is freely programmable, so it can be adapted to non-standard processes, while the other models in the series ensure reliable stand-alone operation in commercial and residential buildings.

How do I change a controller's purpose if the system configuration changes?
With Danfoss ECL devices it is enough to change the application program by selecting the relevant key for the new hydraulic scheme. You will find more information about controller schemes in the Danfoss automation article.
