SAFETY OF USE
•Before you start using the device, please carefully read this instruction.
•This control device must be installed and connected by corresponding qualified person, who is familiar with the
legislation governing safe use of electrical tools: General rules of the installation of electrical devices (Ţin., 2012,
Nr. 18-816); Safety rules of the operation of electrical equipment (Ţin., 2010, Nr.39-1878); General Regulations of
work equipment usage (Ţin., 2000, Nr. 3-88); Technical Regulation "Safety of Machinery" (Ţin., 2007, Nr.129-
5249) and other legislations, governing this activity. It is necessary to comply with all safety requirements.
•Before connecting the device, check all the connections in order to prevent accidental touch to the electric current;
•Check that wires or cable insulation has no obvious damages, cracks and etc. It is forbidden to use the device if
wires, cables of the device are damaged, as well as other parts of the device;
•If you notice strong overheating of parts and wires, sparking in wires and connectors, or other failures, as well as
feel the smell of burning wires or in case of a power failure, it is NECESSARY to turn off the device from the
power source.
•Before connecting the device to the electricity network, all the connection works of this device must be completed.
•It is necessary to ensure appropriate working conditions, corresponding to the device specifications.
INSTALLATION RECOMMENDATIONS
•It is prohibited to connect this device to the same electrical cables without appropriate network filters, to which
other high-power devices are connected.
•Do not route signal cables near or with energy and power cables.
•Keep a distance of remotely operated devices, avoid high-power overload, avoid device contact with group or phase
control devices, as well as other devices, which may interfere the operation of boiler’s regulator.
•When connecting the device, remember that the buildingsystem must be equipped with the connector and automatic
connector. This element has to be close to the controller, easily accessible by the user and marked in a way it would
be clear that it is for the switching off the device.
•The manufacturer is not responsible for damages caused by failure to comply with these instructions.

PURPOSE
VAL-01 controller is an innovative microprocessor device, which regulates the work of solid fuel boiler Stropuva. The
application of the control device and complex algorithms ensures easy use and automation of the combustion process. This
control device is adapted for work with the central heating pump. This controller also has a possibility to connect with the
room thermostat (not included in the kit), with the help of which you can change the operating parameters of the boiler,
when the temperature of the premises reaches a certain temperature. Depending on the purchased room thermostat, you can
program hourly, daily, weekly, etc. modes.

OPERATING PRINCIPLE
The device works on the principle of oxygen dosing. Oxygen is supplied through the fan and dosed byregulating the opening
angle of the air shutter with the help of electric gear. In this way, combustion process is being controlled. When the hot
water reaches the set temperature, the controller simply starts to maintain the temperature and depending on external
parameters can top the combustion process from 10 minutes to 5 hours. After disconnection, fuel is ignited automatically
with the help of blowing ventilator, which is connected to this controller. Boiler’s work can also be regulated with the room
thermostat. In this way, it is possible to regulate heating according to the current room temperature. The controller is
equipped with an automatic system (which detects the temperature sensor failure) and boiler controlling equipment, which
protect the central heating system.

CONTROL PANEL
Pause switcher:
0 – 10 min
1 – 30 min
2 – 60 min
3 – 90 min
4 – 120 min
5 – 180 min
6 – 240 min
7 – 300 min
Switcher of fuel types:
0 – wood:
1 – carbon
2 – peat briquettes
3 – wood sawdust briquettes
4 – wood sawdust granules

Operating modes of the indicator:
Blue color lights – STOP mode. Air supply shutter is closed; ventilator does not work. In this mode, you can load the
boiler with fuel and start it up.
Red color lights – initial control. After starting up the boiler and fuel burning well, you have to unhook the ring of the line
(lower air distributor on the fuel), press start/stop button START/STOP, wait 10-15 seconds until air supply shutter opens
and close the door. Red indicator will light up – initial control. The initial fuel ignition phase is in this mode.
Red/green/blue color flashes – the main control. This mode will be activated, if boiler’s operating temperature will not
reach 70 degrees or due to termination and restoration of power supply to the controller.
Blue/red color flashes – no power. The controller is equipped with a reserve accumulator, so in case of power failure, air
supply shutter will close automatically.
Green color lights – conditioning before the pause. The boiler is extinguished gradually by limiting the air supply. This
mode will be activated when temperature in the boiler will reach 80 degrees or when premises will be warm enough and
room thermostat will be activated.
Red color flashes - pause. This is boiler’s standby mode, during which the air supply to the boiler is completely limited
and the circulation pump is turned off. The boiler is extinct for a specified period of time or until room thermostat will
give a signal to heat the house and at the end of a specified timeout period. After pause, the initial control mode turns on
and the process is repeated.
Red/green flashes – 6 h pause. Fuel clean out turns on at longer than 6 hours pause.
Blue flashes –burning out of coals. When fuel burns out and boiler’s temperature reaches 35 degrees, then coals burning
mode turns on, during which air is blown into the boiler to the maximum. After coals burning out the boiler switches to
STOP mode.
Blue/green flashes – problem with sensor. It is prohibited to burn the boiler at this mode. You need to check connection
contacts of the temperature sensor and to fix the connection or contact the service department.
