Info-3: To connect the outdoor NTC probe, firstly PP15 Outdoor sensor type parameter’s value must be changed to Outdoor sensor available (1). Outdoor temperature measurement starts only if PP15 is selected as 1. If PP15 is selected as 1 and outdoor NTC probe is not connected F6 error code is shown on the display but boiler keeps working.

11. HATA KODLARI (Error Codes) FAILURE FAILURE TYPE DESCRIPTION CODE When heat demand is available, if APS is closed for 15sec although FAN Air Pressure Switch short is stopped, this error is given. When APS is opened, normal operation is started automatically.
If CH Flow NTC is higher than 90°C during DHW operation, burner is CH NTC High Temperature stopped and F16 error is given. When CH Flow NTC is below 80°C error Error During DHW is cleared and normal operation is restarted. When DHW flow is closed during this error, error is cleared.

CH HEATING MODE CH Heating Mode is enabled when P3 Knob is on winter position otherwise CH mode is disabled. If the water temperature, measured by the CH flow NTC probe, is under the low limit (CH flow temperature ON in table 1) for the CH set-point and heat demand is requested on room thermostat input (when PP30 is selected as ON_OFF room thermostat available);...

OPERATION WITH OUTDOOR NTC PROBE The system is prearranged for the connection to an NTC sensor, which measures the external temperature outside the building in which the installation is placed. The available adjustments in this heating mode are the calculated center CH Set Temperature and the heat dispersion coefficient of the room walls.
SERVICE REMINDER FUNCTION Service reminder function will be activated if the input power is supplied to the control board for 7500 hours. SE will be displayed together with the service icon on the user interface. Control board continues normal operation during service reminder function. Service reminder must be cancelled by RESET knob.
GAS CONVERSION This device is useable with only naturel gas. LPG version is not available, so gas conversion isn’t necessary. 14. GAS PRESSURE ADJUSTMENT As the heating capacity of the device is directly dependent on gas pressure, the device’s (mechanically) minimum and maximum heating capacity becomes adjusted by the determination of operation pressure range.

Setting the maximum outlet pressure; The device is taken to maximum operation position. Gas outlet pressure measurement port’s screw is loosened. U manometer is connected to gas outlet pressure (ø9 mm) measurement port. After removing the protection cap of maximum pressure regulator’s adjustment screw –shown by no 2 in Figure- , the gas flow towards the burner increases by slowly turning it clockwise, and otherwise it decreases.
16. MAIN COMPONENTS Mainboard The mainboard operates at 230V AC, 50Hz and controls the gas valve, fan, circulation pump and 3-way valve. A dynamic air pressure test is performed before each ignition cycle. The limit thermostat provides an extra level of safety. Whether or not the burner is flame is continuously checked by ionisation.

Hydroblock There is a pump, 3 bar safety valve, filling valve, water pressure sensor, plate exchanger, turbine, 3 way motorized valve and immersion/surface NTC on this hydroblocks. The pump suction is from the left side of the pump and the exit is upside as shown in the figure below. Filling Tap Filling tap has a basic structure.

Maximum Power Speed Stage Pump Water Outlet Connection G3/4 (External Thead) Manometer Connection Closed Drain Valve Integrated pump Water Pressure Sensor The water pressure sensor prevents the device from operating at low water pressure. When the water pressure at the central heating circuit falls below 0.4 bar, the normally open water pressure sensor closes and blocks the operation of the mainboard combination with the signal from the water pressure sensor.
Page 20
3 Bar Safety Valve The 3 bar safety valve protects the central heating circuit and the device against a possible increase in pressure. When the water pressure at the central heating circuit exceeds 3 bar, the safety valve is opened to reduce the water pressure (safety valve output drainage should be provided).
Page 21
Expansion Vessel The expansion tank meets the expansion of the hot water circulating in the central heating (heating circuit) circuit, which is a closed circuit system. Tank volume is 6 litres and inlet connection point is G3/8 (external thread) Differential Air Pressure Switch (APS) The differential air pressure switch is used in hermetic models.
