Parameters Setting - Baxi DUO-TEC MAX+ Instruction Manual

14. PARAMETERS SETTING

To programme the parameters of the boiler electronic board, proceed as follows:
• Press and together and hold them down for 6 seconds until programme row "P01" appears on the display alternated
with the set value;
• Press to scroll the list of parameters;
• Press the value of the selected begins flashing, press
• Press to confirm the value or press
Further information concerning the parameters listed in the following table are supplied together with the required
accessories.
DESCRIPTION OF PARAMETERS
P01 Manufacturer information
Gas used
P02
00 = METHANE - 01 = LPG
P03 Hydraulic system
Programmable relay 1 settings (See SERVICE instructions)
00 = no associated function
01 = relay contact closed with Room Thermostat demand (230V)
02 = relay contact closed with Remote Control demand (low voltage)
03 = system fill contact
04 = boiler faulty signal contact
P04 05 = fan contact (kitchen fan)
06-07 = not used
08 = timed contact for enabling external DHW pump
09 = timed contact for enabling external DHW circulation pump via DHW
programming from remote control
10 = relay contact closed with DWH demand active
11 - 12 - 13 = not used
Programmable relay 2 settings (See SERVICE instructions)
P05
Same configurations as relay 1 - P04
External probe input configuration
P06
(See SERVICE Instructions)
P07..P09
Manufacturer information
Heating setpoint setting OT / RT
(Remote Control - Open Therm / Room Thermostat 230V~)
00=the temperature request is the Remote Control setpoint
01=the temperature Request is the highest setpoint between Remote Control
and PCB
02=the temperature request is the Remote Control setpoint. The Room
Thermostat enable the gas boiler operates
P10
03= the calculated setpoint depends on the origin of the request (PCB or
Remote Control):
a)PCB (Ambient Thermostat): the setpoint is set by pressing the +/-
buttons on the boiler control panel, after having first disconnected the
Remote Control from the boiler.
b)Remote Control: the setpoint is set by modifying the "ULt" parameter
(see Room Unit accessory manual, chapter "INSTALLER FUNCTIONS")
c)Simultaneous request PCB - Remote Control the higher setpoint of the
two requests is satisfied.
P11..P12 Manufacturer information
P13 Max. heating output (0-100%)
P14 DHW max. output (0-100%)
P15 Min. heating output (0-100%)
Maximum CH setpoint (°C)
P16
00 = 85°C - 01 = 45°C
P17 Pump overrun time in heating mode (01-240 minutes)
P18 Burner ignition delay in CH mode (00-10 minutes) - 00=10 seconds
P19 Manufacturer information
P20 Pump overrun time in DHW mode (seconds)
