General questions

Unfortunately, we don’t plan for selling the eCoal.pl controllers to private/individual customers for a few reasons, with one, and most important, being caution: insufficient experience with central heating systems could lead to incorrect installation or startup.

We offer the controller to professional boiler installers certified by the Polish Institute for the Chemical Processing of Coal. Visit the “Kotły co – poradnik użytkownika portal for reliable information of solid fuel boilers.
Each automatic boiler has problems with burning coking coals with high Rogi Index. The coal coking process blocks air access to the fuel which produces problems with afterburning. High calorific value is not the key criterion in choosing fuels for boilers with automatic feeders. Possible solutions include adding a fuel with low Rogi Index (the process of production of “qualified fuels”) or biofuels such as grain, rye, wood chips, etc. Note that even the presence of slag in ash does not have a significant effect on boiler efficiency. Coke can be afterburned by feeding large quantities of surplus air, which users do by selecting manual burning mode. Without flue gas temperature control this manual mode produces huge chimney loss.

Also, the burner crown must be checked for leakage. The crown should be bonded with silicone resistant to high temperatures (up to 1,200°C). If the burner has secondary air holes (see the picture below), these must be sealed with the same type of silicone.

The best method for reducing (adjusting) ambient temperature is installing thermostatic controllers on the radiators and selecting appropriate settings. If the radiators have no control valves, you can install a 4D valve in the central heating circuit to reduce water temperature. If the foregoing cannot be done, lower the temperature preset of the boiler as much as possible and enable the room controller. The room controller requires the indoor temperature probe (included in the controller pack) for correct operation. The indoor temperature probe should be installed at the “reference” (or “master”) room. Further, enable cyclic pump operation (“Ustawienia zaawansowane” , PIN 7492). Experiment with the pump ON/OFF times by observing ambient air temperature.

Our servers use secure SSL protocol using the 256-bit AES key. The SSL is currently one of the most secure data protection methods. For instance, it is used to secure financial transactions.

Your connection is safe when you see “https://...” (instead of “http://...”) at the beginning of a Web site address.

We have a SSL certificate issued by Unizeto Technologies S.A., which confirms that connections established with our servers are:
  • Secure: encrypted for data transmission security;
  • Reliable: authenticated in terms of Web site identity;
  • Trustworthy: provided in conformity with international standards.

All user passwords stored in the “eSterownik.pl” portal are written to a database after encryption by algorithms based on one-way secure hash algorithms. This means that no one can access user passwords (even the administrators of the portal).

Each data exchange session between the eCoal.pl or bruli.pl controller and the “eSterownik.pl” portal server is secured with a random login and password generated for each session.

Also the “eSterownik Mobile”application uses the SSL protocol and “hashes” instead of open passwords.

Questions about installing the controller

The RS-232 connection is required for updating the controller’s software. If your PC has no RS-232 interface, you can buy an USB-RS232 adapter (we recommend DIGITUS products). Connect the adapter to the USB port. Currently, virtually all computers are equipped with such ports.
No. The cable comes with the controller.

However, if you need a longer cable, you can make it yourself using the following connection diagram:

The SD memory card is used for logging the following operating parameters recorded by your eCoal.pl or bruli.pl controller:

  • Historical temperature measurements that are taken by probes every 60 seconds;
  • Temperature presets for central heating water and hot utility water;
  • Alert triggering and resetting events;
  • Controller operation mode changes;
  • Controller ON/OFF events;
  • Controller’s Internet link usage;
  • Visiting statistics.

You can view all logged events directly in your Web browser.
The controllers support all Secure Digital (SD) cards (24 x 32 mm).
Use a semiconductor temperature probe such as KTY81-210. Connect it to the terminals on the terminal strip inside the control box marked as “T.WEW” [Indoor Temperature] with a two-conductor cable with conductor cross-section not smaller than 0.25 mm2.

The flue gas temperature probe is a Pt-100 type device, with all the remaining temperature probes being KTY81-210 devices. This means you can switch between the KTY81-210 probes (any KTY81-210 temperature probe connected to the “T.WEW” [Indoor Temperature] terminals will act as the indoor temperature probe).

We encourage all users of the eCoal.pl and bruli.pl controllers to connect an indoor temperature probe to the controller. This is a low-cost (a few dollar) and easy to install (preferably with the box selected to the wife’s preference) solution for evaluation of temperature adjustment efficiency.

KTY81-210 probe in a box

If you do so, the controller will save this information on the memory card and you will be able to review temperature graphs for better energy management.

In addition, an outdoor and indoor temperature probes will enable using a weather controller and a room controller, respectively.

The eCoal.pl and bruli.pl controllers support KTY81-210 type temperature probes.

KTY81-210 temperature probe in a box

The eCoal.pl and bruli.pl controller support KTY81-210 and PT100 probes (the latter for flue gas temperature). We offer different probe designs:

Central heating water temperature probe with integral thermal protection (KTY81-210)

Fuel feeder temperature probe (KTY81-210)

Indoor/outdoor temperature probe (KTY81-210)

Hot utility water temperature probe (KTY81-210)

Flue gas temperature probe (PT100)
You can only use a UPS with sinusoidal output current. Our controllers do not support UPSs with rectangular output current pattern.

Questions about controller operating algorithm

The causes are the following:

1. Insufficient flue gas temperature reported (less than 70°C), interpreted by the controller as no burning:
  • Sensor covered with soot (clean the sensor regularly by removing it from the flue gas conduit and re-inserting);
  • Probe tip not in the flue gas stream (too deep or too shallow insertion; position the tip in, or near, the centerline of the conduit);
  • Probe tip covered with ash (clean the conduit);
  • Incorrectly calibrated flue gas probe (re-calibrate using the advanced settings);

2. Excessive flue gas temperature reported (more than 400°C) meaning probe fault (replace the probe).
We provided the “AutoLato” [Auto-Summer] modes in the eCoal.pl controller in response to the requirements of our customers. You can select the following modes in the advanced settings:

  • AutoLato-temp.” [Temperature-driven Summer/Normal mode selection]: The controller selects automatically the Summer (hot utility water only) or Normal (hot utility water and central heating) mode based on outdoor temperature measurement.
  • AutoLato-prog.” [Time program-driven Summer/Normal mode selection]: The controller sets the respective mode based on programmed time periods.
The programmer has the same functionality as the room thermostat. It enables you to define day and night temperature (higher and lower, respectively) to be maintained in the “reference” (or “master”) room. The room programmer requires an indoor temperature probe.

Circuit operation:
  • If the room temperature is lower than the preset, the boiler is set to normal (comfort) temperature.
  • Where the room temperature increases above the preset, the boiler will be set to reduced temperature.

If a reduction of the preset central heating water temperature results in room overheating, enable cyclic pump operation (see: advanced settings, pump operation mode).

Questions about using the control panel

The down arrow displayed when a central heating or hot utility water temperature preset is active means that the temperature was reduced by the value preset in the User Settings. This can result from the following:

  • Room thermostat contactor open during thermostat-driven temperature control;
  • Preset temperature lowered in the central heating water temperature, hot utility water or weather controller;
  • Excessive indoor temperature during room programmer-driven temperature control.
The letters represent controller operation modes.

  • The first line displays (from the left) the status of the central heating system:
  • CO: Information on the status of the central heating system;
  • XX.X: Current boiler output temperature (central heating water temperature);
  • XX: Boiler output temperature preset;
  • ↓: Reduced temperature symbol.

Last letter in the first line:
  • C: Enabled control by the central heating water temperature programmer;
  • P: Enabled control by the weather programmer;
  • K: Enabled control by the room programmer;
  • T: Enabled control by the outdoor thermostat;
  • R: Manual control.

The second line displays (from the left) the status of the hot utility water system:
  • CWU: Information on the status of the hot utility water system;
  • XX.X: Current hot utility water temperature;
  • XX: Hot utility water temperature preset;
  • ↓: Reduced temperature symbol.

Last letter in the second line:
  • N: Hot utility water “Normal” mode;
  • P: Hot utility water “Priority” mode;
  • L: Hot utility water “Summer” mode;
  • R: Manual control.
The “ERR” message in the measurement section of the LCD means that a temperature probe is faulty (shorting or gap in the measuring circuit). If you see this message, have the Service replace the probe.

The bruli.pl controller detects temperature probes automatically. Each probe is automatically diagnosed on powering the controller. If any probe is faulty (gap in the measuring circuit) and you fail to notice the problem, the faulty probe will not be detected the next time you power the controller, which means that the device depending on for temperature measurements will remain disabled.

This does not apply to the central heating water temperature and flue gas temperature probes as these are essential for the operation of the controller.
The heat support mode settings should be evaluated on the basis of the boiler operating parameters saved on the memory card. The support time should prevent the boiler from going out (based on flue gas temperature increase during fuel feeding) and, on the other hand, the setting should not produce boiler temperature increase in the Summer mode (based on evaluation of the central heating temperature change in the heat support mode).

Questions about PC software

The simplest procedure for checking the COM port number assigned to the USB-RS232 adapter is as follows:

  • Disconnect the USB-RS232 adapter from your PC.
  • Right-click the My Computer icon and select the Properties command in the popup menu.
  • In the displayed window select the "Device Manager” option (located in the “Hardware” tab in Windows XP).
  • Expand the “Ports (COM and LPT)” item on the hardware list.
  • Re-connect the USB-RS232 adapter to the PC and wait for a new "USB Serial Port (COMxx)” device to appear on the list.
  • You will see the COM port number in the brackets.
  • If you fail to note the change, disconnect and re-connect the adapter again.

Definitely yes. We are continuing to develop the eCoal.pl and bruli.pl controller software: we add new functionality, improve the source code.

Questions about Web browser access to the controller

Each controller, both eCoal.pl and bruli.pl has an Ethernet module with RJ-45 interface. The controller has an IP address and an “internal Web site” that can be accessed from any PC connected to the controller’s LAN. The connection is direct, without any adapter.

The controller acts as a Web server. Type its IP address in your Web browser and you will see the controller’s main site: central heating system diagram. There are two access levels: read only and read-and-write. You can control the equipment connected to the controller, including programmers, and view the graph archive.
Google Chromeis the preferred browser. 

Alternatively, you can use Mozilla Firefox v. 2.0 or later  or Opera 10.60.

Internet Explorer is not recommended because of the lack of support of the latest standards.
The controller is connected to a LAN in the same way as any PC: with a cable terminated with RJ45 on the both sides, one connected to a router or switch. One more thing is the setting of the IP address, subnetwork mask and gateway. The “Zdalny dostęp” [Remote Access] service provides access to the Internet.

The dedicated Web portal provided specifically for the users of eCoal.pl and bruli.pl controllers enables remote access by each user without his/her own public IP address. The intermediate server enables communication with the controller that has not been assigned a public IP address. Click the „Zdalny dostęp” [Remote Access] tab, register and add your controller. All information is available from the Web site.
