Product information

Description

TECH ST-19 is a pump controller for central heating (CO) systems designed to manage circulation pump operation in residential and light-commercial installations. The compact black housing contains control electronics that start and stop the pump according to system demand and include an anti-stop function to actuate the pump at intervals, reducing the risk of seizure during prolonged inactivity.

Advantages

The controller provides reliable automatic pump control with a simple installation footprint and straightforward wiring compatible with typical heating circuits. Its anti-stop feature periodically runs the pump to prevent blockages and bearing damage, improving pump longevity and reducing maintenance needs. The black enclosure offers a neutral appearance that integrates with common boiler and pump assemblies.

Suitable for

Managing circulation pumps in domestic central heating systems
Light-commercial heating circuits with standard pump motors
Retrofit projects where anti-stop protection is required
Systems where compact controller mounting is needed near the pump or boiler

Key specifications

Function: automatic pump start/stop control for central heating
Anti-stop feature: periodic pump activation to prevent seizure
Housing colour: black
Compatibility: intended for standard circulation pump motors used in CO systems
Application: residential and light-commercial heating installations

How to use

Install the TECH ST-19 controller according to local electrical and heating codes, mounting it close to the circulation pump or boiler for convenient wiring. Connect supply and pump control conductors following the wiring diagram provided by the manufacturer. Once powered, the controller will automatically run the pump based on system signals or its internal control logic and will activate the anti-stop routine during extended idle periods. Verify correct operation at initial start-up and after commissioning by observing pump behavior during normal heating cycles and anti-stop intervals.

Usage recommendations

Use only with compatible circulation pumps and within the electrical ratings specified by the system installer or manufacturer. Periodically inspect wiring and mounting for signs of wear or corrosion and test the anti-stop function after long idle periods or seasonal shutdowns to ensure continued protection.
