Parameter P01; It controls the outlet gas pressure of gas valve during ignition period.
Default setting of P01 ignition capacity is 16 %.
Parameter P02; This parameter is used to identify the type of gas that is used. The default
value of this parameter is adjusted for natural gas (00).
Parameter P03; It is used to identify the burner switch ON delay in CH mode. During a CH
demand, burner is switched OFF when T flow sensor is greater than T set + 5 ºC while pump
is running. When T flow sensor is lower than T set -3 ºC, burner is switched ON after the
delay fixed by the parameter P03.
Parameter P04; While adjusting P4 parameter, burner power follows trimmer P5 changes.
Parameter P05; If parameter 5 is OFF (00), CH range is normal (30ºC-80ºC), if it is ON
(01), CH range is reduced (30ºC- 50ºC), which is suitable for floor heating applications.
Parameter P06; If parameter 6 is ON, burner is switched ON and OFF according to set point.
If parameter 6 is OFF, burner is switched ON and OFF according to a fixed set point.
Parameter P07; If P07 is selected to be 00, the LED illumination is always ON. If this
parameter is 01 than, the LED lights will be ON when there is flame and if this parameter is
02, LED is always off.

5.1.1 Parameter menu activation
 In order to enter parameter menu activation, DHW knob must be outside the OFF range.
 Entering parameter menu any running request is respected.
 By pressing the RESET switch for more than 10 sec. P01* appears on the LCD display.
