- After the 11
th
press PB2, the display goes back to “ L 2 ”.
- If PB3 is pressed continuously more than 5 seconds, all LED blink three times and the parameters
are set to the factory defaults (Minimum Power, Maximum Power, Ignition Power, Anti-Cycling
Time, DHW ON-OFF flow rate, OTC curve foot point, Pump Control Mode and Modulation Start
Point). See table 24.
¨ Minimum Power
- The minimum power (heat output), was limited mechanically by means of the adjusment screw
that are on the gas valve, can be increased %0 … % 30.
¨ Maximum Power
- The maximum power (heat output), was limited mechanically by means of the adjusment screw
that are on the gas valve, can be decreased %0 … %20.
¨ Ignition Power
The ignition power can be incerased % 20 … % 70.
¨ Anti-Cycling Time Adjustment
- Anti-cycling time restricts CH demands for a certain time to prevent the boiler from frequently
goes ON (CH mode) or OFF (stand-by). The factory defaults of anti-cycling time is 3 minutes and
also can be adjusted between 0 and 15 minutes.
¨ DHW ON-OFF Flow Rate
- DHW ON-OFF flow rate (ltr/min) can be adjusted as F1: ON=3 OFF= 2,5 or F2: ON=3,5 OFF= 3.
¨ DHW Delay Time
- In order to avoid water hammer effect in DHW mode, DHW delay time can be adjusted as d2: 1
(sec) or it can be adjusted as d1: 0 (sec) for inactive the function.
¨ OTC Curve Foot Point
Foot point, defines the bottom point of the heating curves (please see page 40 FORTIUS
Installation and User’s Operating Instructions), can be adjusted between 10
o
C … 50
o
C.
¨ Outside Temperature Limiting Set Point
By means of this value, it can be defined from an outside temperature more than 18º C, the heating
process (burner and the pump) will be automatically activated (o1) or inactivated (o2).
¨ Pump Control Mode
a) Mode 1 should be selected when a room thermostat is not connected to the boiler. In this
condition, when heat demand (CH or DHW) ends, pump stops after pump over-run time
b) Mode 2 should be selected when a room thermostat is connected to the boiler. In this condition,
CH temperature sensor controls only gas circuit. The room thermostat controls both gas circuit and
the pump. Also, the pump has over-run time. If the boiler is in mode 2 and a room thermostat is not
connected, the pump runs permanently. Pump control mode 2 is factory default.
