5.1.4 PARAMETERS’ ADJUSTMENT

Authorized service can change seven of the parameters related to boiler

operation via using the reset button and knobs on the control board.

1) Ignition Gas Pressure: It controls the outlet gas pressure of gas valve

during ignition period. By using Table 6, adjustment can be done as

percentage.DefaultsettingofP01ignitioncapacityis16%.Incase

of a bursting type of burning, this parameter can be adjusted to meet

sufficient ignition capacity for a proper burning.

2) Gas Type: It makes the adaptation of the electronic board to gas type

change.

3) OFF Time: It is the time between boiler stop and restart again fol-

lowing the heat requirement. The boiler will not restart before this

time. Factory setting is 60 seconds. It can be altered between 0-255

seconds’ period as percentage by using Table 6.

4) Maximum Heat Capacity: It controls the heat capacity by controlling

thegasowpassingthroughthegasvalve.Defaultsettingis100%.

Itcanbeadjustedbetween0–100%.

5) Central Heating Range: The boiler can work in two different modes

using this parameter. There are two choices ‘ON’ and ‘OFF’. Default

setting is ‘OFF: 30-85°C’. The mode ‘ON: 30-50°C’ is recommended

foroorheatingsystems.

6) Domestic Hot Water Switch Off Temperature: It adjusts the switching

point of domestic hot water. There are two choices ‘ON’ and ‘OFF’.

Factory setting is ‘ON: boiler turns off at 71°C and starts at 70°C’.

With the other mode ‘OFF’ the boiler can be adjusted to ‘turn off at

“set + 8 °C” and start at “set + 7 °C”’.

ATTENTION! These adjustments should be done by authorized Alarko

Carrier Services.
