2. OPERATING INSTRUCTIONS
2.1 Introduction
Dear Customer,
ECONCEPT TECH 18 A is a high-efficiency, low emissions sealed chamber premix
condensing heat generator for heating and hot water production (with optional external
hot water storage tank), running on natural gas or LPG and equipped with a microproc-
essor control system.
The sealed chamber unit is suitable for indoor installation or outdoors in a partially pro-
tected place (according to EN 297/A6) with temperatures to -5°C (-15°C with optional
trap antifreeze kit).
The boiler is arranged for connection to an external hot water storage tank (optional).
In this manual all the functions relevant to domestic hot water production are only active
with the optional hot water tank connected as indicated in sec. 3.3.

dicated by flashing of the hot air above the radiator on the display.
The display (detail 11 - fig. 1) shows the actual heating delivery temperature and, during
heating standby time, the message "d2".
Domestic hot water (DHW)
A DHW demand (generated by drawing domestic hot water) is indicated by flashing of
the hot water under the tap on the display.
The display (detail 11 - fig. 1) shows the actual DHW outlet temperature and, during

2.3 Lighting and turning off
Connection to the power supply
•
During the first 5 seconds the display shows the card software version.

Open the gas cock ahead of the boiler.
•
The boiler is now ready to operate automatically whenever hot water is drawn or in
case of a room thermostat demand.
Boiler lighting and shutdown
Press the on/off button (detail 7 - fig. 1) for 5 seconds.
fig. 2 - Turning the boiler off
When the boiler is turned off, the PCB is still powered. Domestic hot water and heating
are disabled. The antifreeze system remains activated. To relight the boiler, press the
on/off button (detail 7 fig. 1) again for 5 seconds.
The boiler will be immediately ready to operate whenever domestic hot water is drawn
or in case of a room thermostat demand.
B
The antifreeze system does not work when the power and/or gas to the unit are
turned off. To avoid damage caused by freezing during long idle periods in win-
ter, it is advisable to drain all water from the boiler, DHW circuit and system; or
drain just the DHW circuit and add a suitable antifreeze to the heating system,
complying with that prescribed in sec. 3.3.
2.4 Adjustments
Summer/Winter Switchover
Press the summer/winter button (detail 6 - fig. 1) for 2 seconds.
The display activates the Summer symbol (detail 10 - fig. 1): the boiler will only deliver
domestic hot water. The antifreeze system remains activated.
To deactivate the Summer mode, press the summer/winter button (detail 6 - fig. 1)
again for 2 seconds.
Heating temperature setting
Use the heating buttons (detail 3 - fig. 1) to adjust the temperature from a min. of 20°C
to a max. of 90°C.
DHW temperature adjustment
Use the DHW buttons (detail 1 - fig. 1 ) to adjust the temperature from a min. of 10°C to
a max. of 65°C.
Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature required in the rooms. If the room ther-
mostat is not installed, the boiler will keep the system at the set system delivery setpoint
temperature.
Room temperature adjustment (with optional remote timer control)
Using the remote timer control, set the required temperature in the rooms. The boiler will
adjust the system water according to the required room temperature. For operation with
remote timer control, please refer to the relevant instruction manual.
