Possible selection: - factory: 3600sec - Minimum: 0 sec - Maximum: 18000 sec This parameter is used only when configuration doesn’t contain room corrector, because regulation doesn’t have information of room temperature. This parameter is time which is presumed that the system will achieve a given room temperature in a transition from day to night mode, and vice versa. So, this is time in which will ”flow temperature“ be optimally adjusted to achieve quick transition.

Operation phases Operation phase

Description - The message on the screen: "IGNITION 2/3". - Fan works on max. speed - Primary / secondary is positioning themselves. - Waiting for the Tdp> 50°C. When Tdp> 50°C: a) The user can confirm the message "IGNITION 2/3" then screen will show the message "IGNITION 3/3" which user also can confirm which exceeds the boiler in the next phase "SP1" or "SP2".

S1

b) If the user didn’t confirm the message "IGNITION 2/3" or didn’t confirm message "IGNITION 3/3" boiler will after 5 minutes automatically switch to the next phase "SP1" and on the screen remains message "IGNITION 3/3" with the inscription "automatic continuation". This message remains on the screen until the confirmation by the user but has no effect on the operation of the boiler. Exceptions: 1. If upper boiler door is opened, there is no possibility of manual confirmation of the message "IGNITION 2/3" either is not possible to automatically move to the next message "IGNITION 3/3". Closing the upper boiler door, boiler moves to above described (normal) procedure phase "S1". 2. If upper boiler door is opened when on the screen is displayed message "IGNITION 3/3" move to the next stage ("SP1") or "SP2" is only possible by using the manual message confirmation while automatically is not possible. - Setting the start position primary / secondary is necessary for the next phase "SP2".

SP1

- When the primary / secondary are adjusted boiler goes into a phase "SP2", - If the required position of primary / secondary had been set earlier, this phase "SP1" doesn’t appear on the screen).

- Before the end of this stage regulation based on the measured parameters of the boiler operation allows the transition to the next phase "SD4" ("DX") or otherwise records information in history and extends this state "SP2" for factory defined time period after which repeats the comparison of the measured and the required parameters and allow you to move to the next stage "SD4" ("DX") or if the conditions are not satisfy writes an error and stops the operation of the boiler. - Set the power blades D4 - If the required position primary / secondary had been earlier set this state "SD4"does not appear on the screen. - Stage "DX" is the common name for operation phases of the boiler on “D4","D3","D2","D1". - phase “DX” doesn’t appear displayed on the screen but is displayed one of the operation of the boiler “D4", "D3", "D2", "D1" which depends about boiler modulation phase. - Indicate that the upper boiler door is opened.

(understage)

DIF1

- Turning off the boiler either due to reaching the set temperature of the boiler, too low combustion chamber temperature or too high flue gas temperature (Tdp>300 °C ).

DIF2

- The boiler wait that the temperature in boiler drops to the set temperature of the boiler reduced by set differential.

DIF3

- Blowout while boiler is waiting that temperature in boiler drops to the set temperature of the boiler reduced by set differential.

DIF4

- Start boiler-setting primary / secondary, after the boiler temperature dropped to the set temperature of the boiler reduced by set differential.

- Shutting down after which the boiler goes into phase „OFF“.

PF-XXXX

- xxxx: Is any phase described above (for example PF-GLW2) - Appears after a power off/power in if there was a power failure. - The prefix "PF" disappears with new start of the boiler or by using option "forced shut down"
