Temperature regulator EL880zPID is designed for central heating boilers. Controls the water circulation pump fo central heating system, hot water circulation pump or valve, mixing valve and fan. Optionally, it is also possible to control the addition of two mixing valves through modules ST-61.

Controller EL880zPID EL880zPID controller is a controller with continuous output signal using a modified PID control algorithm. Fan operation is carried out continuously over time, the fan power depends directly on the measured temperature of the boiler, flue gas temperature and the difference of these parameters and their setpoint values. To maintain a stable setpoint temperature without unnecessary overshoot and oscillations are the advantages of regulator zPID.

Using this type of sensor controller exhaust fuel savings can range from a few to several percent; the temperature of the output water is very stable, resulting in longer life of the heat exchanger (boiler). Checking the flue gas temperature at the outlet of the boiler causes low emission of dust and gases harmful to the environment. Heat energy from the flue gas is not wasted and released to the stack, but is used for heating.
