Tech ST-391 zPID d100 Fireplace Controls

The Tech ST-391 zPID controller is designed to control a fireplace with a water circuit. This controller operates the throttle valve, regulating the air supply depending on the set circuit temperature and the exhaust gas temperature. The TECH ST-391 zPID controller is also responsible for the operation of two pumps: central heating, hot water supply, or underfloor heating. A key feature is the presence of a voltage-free output for controlling an additional device (gas or electric boiler), which will turn on when the temperature in the heating system drops to the set temperature (the fireplace goes out). The controller is equipped with an exhaust (flue) gas sensor and PID control. This type of control monitors the flue gas outlet temperature (keeping it constant).
