The TECH EU-19 is a compact pump controller for heating circuit pumps in central heating systems.
It switches the circulation pump on and off depending on temperature, thereby reducing power consumption and pump wear.
Highlights / Benefits
⭐ Temperature-dependent pump control for energy savings
⭐ Anti-seize function prevents the pump from seizing
⭐ Easy operation via rotary knob and switch
⭐ Manual pump activation possible
⭐ Robust technology for continuous heating operation
Detailed Description
Application Area & Target Group
The TECH EU-19 was developed for the control of water circulation pumps in central heating systems .
It is suitable for private heating systems as well as for smaller commercial applications and is ideal for systems with classic heating circuit control.
Everyday Benefits
By automatically switching the pump on and off only when the boiler temperature is sufficient, the EU-19 prevents unnecessary running times.
This saves electricity, reduces operating costs, and significantly extends the service life of the heating circuit pump.
Technology & Equipment
The pump switch-on temperature is conveniently set via a rotary knob (25–85 °C) .
If the boiler temperature drops 2 °C below the setpoint, the pump is automatically switched off – this avoids frequent switching cycles.
In addition, a manual pump control is available, which is indicated by a dedicated LED.
Efficiency & Protection Functions
The integrated anti-seize function activates the pump every 10 days for 5 minutesto prevent the pump motor from seizing outside the heating season.
The timer setting is retained even during a power failure.
Compatibility & System Integration
The controller is designed for 230 V heating circuit pumps and is integrated directly into the pump's power supply.
An external temperature sensor measures the boiler temperature in the flow line.
