The flue gas temperature sensor measures the heat of the gases leaving through the chimney, allowing the controller to optimise boiler operation and reduce energy losses. It is installed in the flue pipe, and the data it provides makes it possible to fine-tune the heating system's parameters.
The device is optional – it is not required for the boiler to work properly, but it increases efficiency and gives you better control over the combustion process.
Which controllers it works with
The flue gas temperature sensor works with the ProND controllers used in MOCEK boilers: IRYD 620 (OXYPELL, BIOPAL and PRO Pellet boilers) and IRYD RTZ PID (PRO eco-pea coal boilers). It connects to the input labelled as the flue gas sensor in the controller manual.
Why install it
- The controller detects burner shutdown from the drop in flue gas temperature and does not feed fuel "into an empty burner".
- A rising flue gas temperature at the same settings is a sign that the heat exchanger is clogging with soot and needs cleaning – without the sensor, you only notice it on your pellet bill.
- It enables the controller's energy-saving functions, which adjust the fan output based on flue gas temperature.
Installation
The sensor is inserted into a sleeve or opening in the flue pipe (the section between the boiler and the chimney), and the cable runs to the controller's terminal strip. No calibration is required. If your flue pipe has no measuring port, simply drill a hole with a diameter matching the sensor's sleeve. See also the CH boiler sensor KTY 81-210 and other boiler sensors.
Users of the BatoryPell burner may also want to take a look at the range, which includes an inductive sensor for BatoryPell.
If the chimney draught in your installation is sometimes unstable, consider a flue gas exhaust fan, which stabilises boiler operation regardless of the weather.
