PRINCIPLE OF OPERATION – STAGES OF CONTROLLER OPERATION

The user starts the fire-up function by pressing a corresponding icon. The other modes start automatically, depending on the stage of the controller operation.

FIRE-UP

This stage starts when the fire-up function is selected in the controller menu, and lasts until CH temperature reaches the preset value, provided that the temperature does not drop below this value for a pre-set period of time (default setting: 5 minutes). If these conditions are met, the controller enters operation mode. If the controller fails to reach proper parameters to enter operation mode within the pre-defined time, an icon indicating fire-up failure is displayed in the upper left corner of the screen . In such a case, the fire-up process must be started again.

OPERATION

Once the fire-up process is completed, the controller enters operation mode. It is the primary mode of controller functioning when the throttle operation is regulated with SIGMA algorithm, oscillating around the pre-set temperature defined by the user. Instead of Fire-up function, Throttle ON/OFF appears in the user menu. The throttle may be disabled if necessary (e.g. while adding fuel) – then the throttle closes completely.

SUPERVISION

This mode is activated automatically when the pre-set temperature is reached in operation mode. In such a case, the controller closes the throttle completely to reduce the temperature.

EXTINGUISHING

During blow-by stage, the throttle closes and opens at pre-defined intervals (Service menu). After blow-by stage, the controller status switches to extinguished. The extinguishing process may also be activated by disabling the throttle in the main menu.

MAIN MENU

FIRE-UP (THROTTLE ON/OFF)

The aim of this function is to achieve optimum flame in the shortest time possible. The fire-up effectiveness is enhanced by throttle operation. This stage lasts until room temperature reaches a pre-defined value required to enter the operation mode. Once the controller enters operation mode, instead of Fire-up function, Throttle ON/OFF appears in the menu. The throttle may be disabled if necessary (e.g. while adding fuel) – then the throttle closes completely. The extinguishing process may also be initiated by disabling the throttle.

MANUAL MODE

The regulator offers manual mode function. In this function, the voltage-free contact may be activated and deactivated. Additionally, the throttle position may be adjusted manually by changing the degree of opening (%). The throttle will start changing its position about 2 seconds after the change has been introduced.

SETTINGS

1. USE VOLTAGE-FREE CONTACT
   The controller has a voltage-free contact output, whose task is to open/close the contact when the room temperature reaches the value set by the user.
   A voltage-free contact can be used e.g. to switch on an external heating device or as a signal to fire up a pellet boiler.
   NOTE
   The voltage-free contact operation depends on the reading from the room temperature sensor.

2. TEMPERATURE OF CONTACT DEACTIVATION
   It is the threshold temperature value at which the contact will be disabled. The contact operates continuously until it reaches the deactivation temperature.

3. PRE-SET ROOM TEMPERATURE
   When the current room temperature exceeds the pre-set temperature value, the throttle will start closing.

THROTTLE CALIBRATION

Throttle calibration is performed automatically every few hours to ensure its proper position. This function is used to activate throttle calibration manually. Once this option is selected, the throttle moves slightly above its current position, reaches 0 position and moves back to its original position.

NOTE
Check regularly if the throttle is unobstructed. An obstructed throttle may have negative impact on combustion process. Mechanical damage caused by dirt or foreign matter entering the air duct, which may lead to throttle blocking, is not covered by warranty repair.

LANGUAGE

This function enables the user to change the language version of the controller.

SCREEN SETTINGS

These parameters are used to adjust the screen layout.

• Screen brightness – This parameter is used to adjust screen brightness during operation.
• Blank screen brightness – This parameter is used to adjust screen brightness after some time (30 seconds) of inactivity.
• Screen blanking time – This parameter is used to define the time after which the screen goes blank.
• Theme – This submenu enables the user to choose the display colour.
  

PROTECTIONS

This function enables the user to set up menu access protection. Once Auto- lock function is selected, access to the menu is possible only after entering a 4 digit PIN code – 0000. The PIN code may be changed by the user in the PIN code submenu.

FACTORY SETTINGS

This option enables the user to restore factory settings.

FITTER’S MENU

SERVICE MENU

This submenu includes advanced controller settings. These functions should be configured by a qualified fitter and the submenu is secured with a 4-digit code.

FITTER’S MENU

TERNET MODULE

Internet module is a device enabling the user remote control of the heating system. The user can control the status of all system devices on the screen of a home computer, tablet or mobile phone. In addition to the possibility of viewing the temperature of each sensor, the user has the option of changing the temperature values.
After switching the module on and selecting DHCP option, the controller automatically downloads such parameters as IP address, IP mask, gateway address and DNS address from the local network. If any problems arise when downloading the network parameters, they may be set manually. The procedure of obtaining these parameters is described in detail in the instruction manual of the Internet Module.

NOTE
This type of control is possible after buying and connecting an additional control module ST-505 or WiFi RS, which is not included in the standard controller set.

SELECTING TEMPERATURE SENSOR

• Executive module temperature – the controller reads the temperature from the sensor connected to the module via a terminal block.
• Display temperature – the controller reads the temperature from the sensor built into the display. This function is useful when the screen is placed far from the fireplace.
• Wireless sensor – the controller reads the temperature from a wireless sensor.

NOTE
If several sensors are connected to the device, the controller will read the average temperature from them.

SENSOR CALIBRATION

Sensor correction should be performed during installation or after a longer period of using the regulator when the temperature measured by the sensor is different from actual temperature. Range of regulation is -10ºC to +10 ºC with the accuracy of 0,1ºC.
The user can calibrate the module sensor, the display sensor and the registered radio sensors.

SOFTWARE UPDATE

To upload new software, disconnect the controller from the power supply. Insert the USB flash drive with the new software into the USB port. Then connect the controller to the power supply. A single sound signal means that the upload of new software has started.

NOTE
The process of uploading new software to the controller may only be carried out by a qualified fitter. After the software has been changed, it is not possible to restore the previous settings.

SENSOR REGISTRATION

The function allows the user to register an additional sensor. To register, select this function and press the registration (communication) button on the sensor.

NOTE
Up to 8 additional sensors can be registered to the controller.

LIST OF SENSORS

By selecting this function, the user can view the registered sensors.

SENSOR REMOVAL

This option enables the user to remove a registered sensor.

SEMI-AUTOMATIC MODE

After the pre-set temperature has been reached, the semi-automatic mode allows the user to sustain the heating process by moving the throttle from 0 to 40% until the temperature drops to the pre-set temperature reduced by hysteresis. Then the fireplace will switch back to operation mode.

SOFTWARE VERSION
Activate this function and the manufacturer’s logo will appear on the display along with the controller software version.

NOTE
The controller software version number is necessary when contacting TECH service staff.

CONTROLLING THE SYSTEM VIA EMODUL APP

The Internet module is a device which allows remote control of the heating system via the Internet. Using the emodul.eu website, the user controls the status of the system devices and other parameters, e.g. temperature of sensors on the screen of a computer, tablet or smartphone. By taping on the parameters, it is possible to change their operating settings.

→ Before registering the module, it is necessary to create user’s account on emodul.pl (if you do not have one).

→ Once the module has been connected properly, select Module ON.
→ Next, select Registration. The controller will generate a code.
→ Log on emodul.pl, go to Settings tab and enter the code which appeared on the controller screen.
→ It is possible to assign a name or description to the module as well as provide phone number and e-mail address to which the notifications will be sent.
→ Once generated, the code should be entered within 60 minutes. Otherwise, it will become invalid and it will be necessary to generate a new one.

→ Internet module parameters such as IP address, IP mask, gate address etc. may be set manually or by selecting DHCP option.
