Boiler Temperature Controller DK System EKOSTER 200 (model 201601) for heating pump and fan control

DK System EKOSTER 200 (model 201601) is a boiler temperature controller designed to manage the operation of a central heating pump and a fan. The device continuously measures boiler temperature and triggers automated switching of the c.o. pump and ventilation outputs to help maintain set operating temperatures, improve heat distribution and support safe, efficient boiler operation in residential or small commercial heating systems.

Advantages

The controller provides reliable temperature monitoring and timed or temperature-dependent control of pump and fan outputs to reduce manual intervention. Its compact design simplifies installation in boiler rooms and combines basic control functions in a single unit. By automating pump and fan switching, the unit helps stabilise system temperatures and can contribute to smoother heat delivery and reduced wear on mechanical components.

Suitable for (tasks / use cases)

• Control of central heating (c.o.) pump operation based on boiler temperature.
• Control of boiler room ventilation or fan units to assist combustion and heat exchange.
• Use in residential boilers and small commercial heating systems requiring simple automated pump/fan control.
• Replacement or upgrade of basic mechanical thermostatic or time-only controls with temperature-based switching.

When it may not be suitable

This controller is intended for basic temperature-based switching of pumps and fans; it is not a fullbuilding management system or an advanced weather-compensated heating controller. Systems that require complex sequencing, multiple zones, modulating outputs, or integration with smart home platforms may need a more advanced controller. Professional assessment is recommended for larger commercial systems or installations with specialized safety or regulatory requirements.

Key specifications

• Function: Boiler temperature measurement and automated switching for pump and fan outputs.
• Control outputs: Dedicated outputs for central heating pump and fan control.
• Measurement: Continuous boiler temperature sensing for temperature-dependent switching.
• Intended installation: Boiler room mounting for residential and small commercial heating systems.
• Operational goal: Maintain set temperatures, improve heat distribution, and support safe boiler operation.

How to use

Install the controller in the boiler room according to local electrical and safety regulations and connect its temperature sensor to the boiler at the recommended sensing point. Wire the pump and fan outputs to the respective devices, ensuring correct voltage and current compatibility. Set the desired activation temperature or parameters following the manufacturer’s instructions; the controller will switch the pump and fan based on measured boiler temperature. Perform functional tests after installation to confirm correct switching behavior and adjust settings as needed.

What to consider before purchase

• Verify compatibility with your pump and fan electrical ratings and the boiler’s sensor mounting point.
• Confirm that the controller’s basic switching functions meet your system requirements (no multi-zone or advanced modulation features).
• Ensure installation space and mounting style match your boiler room layout and wiring access.

Usage recommendations

For reliable operation, have the controller installed and commissioned by a qualified heating technician, check wiring and sensor placement during installation, and schedule periodic inspections to ensure the temperature sensor and switching contacts remain clean and functional.
