Two types of menu are available in the device:
-the main menu, with capital letters, which may be scrolled by pressing the buttons „+” and „-„ ; to enter a
submenu, press the „F” button
-submenu, which May be scrolled in one direction by pressing the „F” button, the displayed values may be
changed using the „+” and „-„ buttons.
Data are saved every time after displaying the main screen: „TEMP.KOTLA” (“TEMPERATURE OF THE BOILER”).
OPERATIONAL MODES OF THE BOILER
Three modes are available in the boiler: weather mode (recommended), manual mode and summer
mode.
-the weather mode; to operate in his mode, it is necessary to install the supplied CTZ-01 outside temperature
sensor. The operational temperature of the boiler may be selected from the linear approximation of the
programmable heating curve, so it is not necessary to change the temperature manually when the outside
temperature changes. Nights are usually cooler than days. This is the operational temperature of the boiler in
the function of outside temperature.
The user has to program two points on the curve, for the following outside temperatures: -20ºC and –10ºC.

When it is necessary to heat the warm utility water, the operational temperature of the boiler is automatically
changes in order to heat the utility water as soon as possible, and then returns to the operation according to
the heating characteristics.
-manual mode; in his mode, the user sets the operational temperature of the boiler manually. When it is
necessary to heat the warm utility water, the operational temperature of the boiler is automatically changes in
order to heat the utility water as soon as possible, and then returns to the operation according to the
temperature set by the user.
- summer mode; the driver does not activate the central heating pump, except of alarm situations; this mode
is used in summer to heat the warm utility water.
THE SET TEMPERATURE OF THE BOILER
In the weather mode, the set operational temperature of the boiler is calculated from the heating
characteristics, on the base of the outside temperature. In the summer and manual modes, the user enters the
set temperature into the submenu „temp. zadana kotła” (“the set temperature of the boiler”).
HYSTERESIS LOOP OF THE BOILER
The hysteresis loop is a zone of insensitivity to temperature changes. The blower (feeder) turns off
when the boiler reaches the set temperature, and turns on again when the boiler temperature falls by the set
temperature of the boiler diminished by hysteresis.

BRIGHTNESS OF THE DISPLAY
User may adjust brightness of the display in the "display brightness” („jasność wyświetlacza”) submenu.
Display turns off automatically and may be turned on by any button.
POWER OF THE BURNER
The user may choose between the following three levels of the burner operation if necessary:
3 – burner operates with 100% of power.
2 – burner operates with 60% of power.
1 – burner operates with 40% of power.
FEEDER OPERATION
Operation of the feeder is programmed by the manufacturer in accordance with the boiler power.
AIR
For a proper burning process, an appropriate quantity of air is necessary, which depends on the fuel
type and device power. Therefore, an appropriate quantity o fair should be set for every type of fuel and Power
of the device. This should be done by the person who activates the device. These parameters will be saved in
the fixed memory of the driver.
To do this:
-set the appropriate type of fuel
-set the burner power to the 1st degree
-activate the device
-in the “blower power No. 01” („dmuchawa przy mocy nr 01”) submenu, adjust the air quantity using the
buttons „+” and „-„.
This action should be repeated for every value of the device power.
OPERATION OF THE PUMPS
For proper and long-term operation of the boiler, an appropriate operational temperature is necessary.
Therefore, circulation pumps may operate only after exceeding the minima temperature of the boiler operation.
The value set by the manufacturer is 35ºC.
WARM UTILITY WATER
The Pellets heating boiler with the HoGas duo panel perfectly suits for heating of warm utility water
both within and outside the heating season.
The supplied CTN-02 sensor should be fitted to the reservoir of warm utility water.
In the “temperature set for the warm utility water” („temp.zadana c.w.u.”) submenu, the temperature for the
warm utility water should be set. This temperature shouldn’t be too high, in order to minimize the losses of
storage and transmission. The value set by the manufacturer is 45ºC.
When the warm utility water should be heated, the temperature set for the boiler is the temperature set in the
“temperature set for the warm utility water” („temp.zadana c.w.u.”) submenu.
The regulator may operate in two modes of utility water heating (known from gas and oil boiler automatics thus
far) with (recommended) or without priority for warm water. The settings should be made in the “warm utility
water priority” („priorytet c.w.u.”) submenu. In the case of the operation with priority, only the warm utility
water pump turns on to heat the warm utility water, so that the water reaches the set temperature much
faster.
To avoid the temperature fall in the apartment when the pump of warm utility water operates longer than 20
minutes (value set by the manufacturer) but the temperature set for the warm utility water has not been
reached, the central heating pump will be turned on simultaneously for 5 minutes (value set by the
manufacturer).

The warm water hysteresis loop is the parameter which decides on the moment of the warm water heating.
When the water temperature in the reservoir falls below the set temperature diminished by hysteresis, the
heating process begins. It is the same like in the case of the boiler hysteresis loop.
ATTENTION!!! When there is no separate pump for warm utility water or warm utility water reservoir, the
temperature for the warm utility water should be set at 0ºC in the regulator.
ACTIVATION
Press the „Ó” button for 3 seconds to activate the device; the same should be done to turn off the
driver. The current setting will be displayed in the main screen:
OFF – turned off (reaction to alarm situations and manual operation of the blower (fan) and feeder are active)
ON – turned on
WARNING!!! When the display shows OFF, the device operates in standby mode and is still under voltage; in
the case an alarm situation will occur, the appropriate remedial processes will start (the pumps and feeder will
turn on).
If the boiler is not intended to use for a longer time, or in the case of any works near the boiler, it is absolutely
necessary to disconnect the device from the main supply.
The display (main screen) show the current settings of respective appliances. The displayed abbreviation will
have the meaning of e of the device.

-boiler overheating; this alarm is indicated when the boiler temperature exceeds the „alarm temperature of
the boiler” („temperaturęalarmowąkotła”), set in the “SERVICE SETTINGS” („USTAWIENIA SERWISOWE”).
Remedy in this case would be turning on of the circulation pumps irrespectively of the operation mode, until the
boiler temperature turns down.
-feeder overheating; this alarm is indicated when the feeder temperature exceeds the „alarm temperature of
the feeder” („temperaturęalarmowąpodajnika”), set in the “SERVICE SETTINGS” („USTAWIENIA
SERWISOWE”).
ATTENTION!!! If the alarm occurs, it is necessary to find the cause of the alarm situation and repair it.
-the protections are independent from the microprocessor system operation. If the boiler or feeder
temperature exceeds 94ºC, an independent mechanical thermal breaker will start and the power supply to the
blower (fan), feeder and lighter will be disconnected.
ROOM TEMPERATURE REGULATOR
The Pellets driver may function together with any room temperature regulator with shorting contacts.
Intended use and general characteristics of the Auraton-1300 room temperature regulator
The room temperature regulator is intended to function together with the microprocessor driver of the
central heating boiler operation. The regulator allows to maintain a constant temperature in the room.
The room temperature should be set with the regulation crank (according to the instruction
manual of the room temperature regulator). When the existing temperature if lower that the set
temperature, the „HEAT” icon appears. This is also a signal sent to the HoGas duo driver indicating
that the heat energy needs to be supplied to the room. The boiler activates and, if the other
conditions are met, turns on the central heating pump.
The regulator should be mounted in a location representative as regards the apartment
temperature, in the height about 1,5 – 2m.
