Operation Of The Additional Furnace; Feeding Time; Feeding Pause; Blow Force - Tech Controllers EU-48 User Manual

Additionally, the blow force option, in which the user has the possibility to set any rotational speed
of the fan in manual operation is available.

PERATION OF THE ADDITIONAL FURNACE
Tetmo-Tech boilers are equipped with two furnaces:
➔
retort furnace which is fed in sequences with the fuel from the container using a worm feeder,
➔
additional (grate) furnace which is used to support combustion in the event of a long-term pause
in supply of electric power and periodical incineration of wood.
If the operation of the additional furnace function is switched off, the boiler operates on the basic
grillage with automatic feeding of fuel. In the case of activation of this function, the feeder is disconnected
and fuel feeding is carried out manually, just like in the case of backfill boilers.
NOTE
If this function is activated, the options in the menu marked with (*) are not present.
3.5 F *
EEDING TIME
This option is used to set the operation time of the fuel feeder. The operation time should be set
depending on the used fuel and the type of the boiler.
3.6 F
EEDING PAUSE
The pause time is used to set the feeder's operation pause. The pause should be adjusted to the
type of fuel combusted in the boiler. Incorrect selection of the operation time and the pause time may
result in flawed functioning of the boiler, i.e.. the fuel cannot be reheated or the boiler cannot achieve
the set temperature. Selection of proper times allows correct operation of the boiler.
3.7 B
LOW FORCE
This function controls the rotational speed of the fan. The adjustment range is between 1 and
100%, (it can be assumed that they are the gears of the fan). The higher the gear the faster the fan is
operating, where 1% is the minimum speed of the fan and 100% is the maximum speed at which the
fan can operate.
3.8 O
PERATION MODES
In this function, the user selects one of four boiler operation options.
3.8.1 House heating
When this option is selected, the regulator switches to heating the house only. The central heating
pump starts to work above the pump activation threshold (preset at 40
the pump stops working.
3.8.2 Reboiler priority
In this mode the reboiler pump (C.W.U.) is turned on first, until the set temperature is reached. After
reaching the set temperature of the reboiler, the central heating pump shuts down and causes activation
