Technical description and ways of regulation of the ATTACK PROFI boiler
Boiler temperature is kept at the level set at by user by means of control of the flue gas
ventilator´s rotations. Regulator measures temperature of water in boiler, indicates it on display
and controls suction fan and circuiting pump. Regulator is equipped with additional flue gas
thermostat and terminals to connect its sensor. Adequately to the situation, it is possible to use
thermostat to set the flue gas temperature for indication of fuel shortage and boiler stop, or for
setting of required temperature in the room. In dependence of the chosen usage, the sensor of
the flue gas temperature or the sensor of the room temperature should be connected into
terminals for connection of the flue gas thermostat and an adequate mode of regulation should
be chosen through parameter setting. From production is thermostat used for setting of flue gas
temperature. When it is set up for the first time, producer recommends to set value of the flue
gas thermostat in the range of 100-120°C. Temperature is set by button of the additional
thermostat in the temperature display mode. When the flue gas temperature decreases, the
boiler is switched into the mode of fuel shortage. Design of appliance also enables connection
of external contact thermostat into the terminals of the room temperature sensor.
Connection
Before you start appliance by the main switch, connect regulator, ventilator, circuiting pump
and connection cords into suitable sockets in the rear part of appliance. Sensor of boiler
temperature has to be placed into the boiler case.
WARNING! Before you connect regulator into the mains, check, if it is properly
!
grounded and if the terminal screws are fitted well.
ATTENTION! Max. total output of the appliances connected regulator must not exceed
!
450W.
ATTENTION! For extended function of regulator, it is possible to connect the UM-1
!
Module that enables control of additional boiler or C.H. pump. Connection of additional
appliances to module's contacts have to be separated by appropriate relay.
The unused contacts of this module can stay unc
Operation
After start of appliance, all points of display light for a while to check their correct function.
After reset, the regulator switches back to the last state before stop or power shortage.
Basic operation of appliance is controlled by setting of required boiler temperature set by
thermostat, all other functions are performed adequately to parameters programmed in the
service mode. In case that the boiler temperature setting is changed by the boiler temperature
button, the change is indicated on display for several seconds (e.g. [C 75] ) and this value
represents temperature that will the regulator struggling to achieve. This value can be checked
in the temperature display mode. In accordance to the type of installation and service settings
can be the button of additional thermostat used to set flue gas temperature or room temperature.
From production is this button intended to set the flue gas temperature. When the flue gas
temperature decreases under the set value, the regulator switches into the mode of fuel shortage
control and after the set time period - parameter [Fb30] - is the boiler stopped. This function
prevents from eventual discharging of accumulation tank after fuel burn-out in the boiler, when
- after expiration of time set by parameter [Fb30] - ensures boiler operation stop to avoid of
inverse heat flow from charged accumulation tank into cold boiler. Change of position of the
button of additional thermostat is for few seconds indicated on display, e.g. [100°].
