## Summary description

TECH ST-880 zPID is a black controller designed for solid fuel (feed) boilers. It provides PID-based regulation of boiler temperature and combustion air, enabling automatic control of fuel feed systems and fan modulation. Suited for automation of heating systems, improving combustion stability, reducing manual adjustments and supporting scheduled temperature control in residential or small commercial boilers.

## Long description

TECH ST-880 zPID for solid fuel boiler, black is a controller designed to automate temperature and combustion air management in solid fuel (feed) boilers. The unit uses PID-based regulation to maintain stable boiler temperature, control fuel feed systems and modulate the fan. The compact black housing is intended for installation on residential and small commercial heating systems where reliable automatic control reduces manual intervention and helps follow scheduled temperature setpoints.
Advantages
The controller implements PID algorithms to provide precise temperature control and improved combustion stability. Integrated outputs allow coordinated control of fuel feeding mechanisms and combustion air fans, reducing temperature fluctuations and fuel waste. The device supports scheduled temperature changes and can be adapted to different boiler setups, enabling more consistent operation and easier daily management of the heating system.
Suitable for
 Automatic regulation of residential solid fuel boilers with feed systems
 Small commercial heating systems requiring fan modulation and fuel feed control
 Upgrades to manual boilers to enable scheduled temperature control and improved combustion efficiency
 Systems where reduced manual adjustments and better temperature stability are desired
Key specifications
 Control method: PID-based temperature regulation
 Functions: boiler temperature control, combustion air (fan) modulation, fuel feed management
 Housing color: black
 Intended fuel type: solid fuel (feed) boilers
 Application: residential and small commercial heating systems
How to use
Install the controller according to the boiler manufacturer’s wiring and mounting instructions, ensuring correct connection of temperature sensors, fan output and fuel feed actuator. Configure basic PID parameters and set desired temperature setpoints or weekly schedules via the controller interface. Monitor system behavior during initial operation and adjust PID tuning and fan modulation limits as needed to achieve stable combustion and target temperatures.
Usage recommendations
For reliable performance, verify sensor placement for accurate temperature readings, use recommended safety interlocks on the fuel feed and fan circuits, and perform initial PID tuning gradually while observing boiler response. Regular inspection and maintenance of the boiler, feed mechanism and fan will support efficient operation when automated by the controller.
