5.1 INSTALLATION PARAMETERS
These parameters must be adjusted by the installer to match the requirements of the installation.
To access to installation parameters menu:
‐
Ensure the rear mounted power on/off switch is turned on.
‐
Ensure the main display front panel is turned off by using the
button.
‐
Press and hold the
and
buttons together for at least 5 seconds.
To move forward or backward through the menu use the
and
buttons respectively.
To modify a parameter:
‐
Select the appropriate value e.g. –P00, P01, P02, etc.
‐
Press the
button to display the current setting.
‐
Modify the setting as required using the
and
buttons.
‐
To confirm the new setting, press the
button once.
After setting the various parameters it is necessary to validate by pressing the
button for 3 seconds.
Note - If this is not done after completing changes, none of the changes made will be saved.
IMPORTANT
- If none of the buttons are pressed for 30 seconds, the installation parameter menu will be automatically
closed without validating/saving any changes.
Boiler type.
If the boiler is for central heating and Domestic Hot Water (DHW) this parameter is 1. If the
boiler is only for central heating it will be 0.
Model.
18 corresponds to model MAC18, 15 corresponds to model MAC15.
Boiler maximum output limit.
Model MAC18 can be limited to 18 - 15 - 12 - 9 - 6 - 3 kW.
Model MAC15 can be limited to 15 - 13 - 12 - 11 - 10 - 9 - 8 - 7 - 6 - 5 - 4 - 3 - 2 kW.
Underfloor
heating.
If the boiler is underfloor heating ready this parameter will be 1 otherwise it will be
0.
Outdoor temperature probe.
An outdoor temperature probe (not provided) can be installed. In this
case the parameter value will be 1.
Heating temperature differential.
The heating temperature differential can be selected from 2ºC to
10ºC. The default value is 2ºC.
DHW temperature differential.
The DHW temperature differential can be selected from 2ºC to 8ºC.
The default value is 2ºC.
Modulation.
1 (modulation ON)
0 (modulation OFF).
Units.
ºC (Celsius)
ºF (Fahrenheit).
Legionella.
1 (Legionella protection ON)
0 (Legionella protection OFF).
To access the parameters menu from
P11 – P15
, an outdoor temperature probe must be installed and the parameter in
P05
set to
1
AUTO heating regulation
. If a fan outdoor temperature probe is installed it is possible to activate the
auto heating regulation by shifting this parameter value to 1.
TIMAX.
Maximum water flow temperature in AUTO heating mode.
TIMIN.
Minimum water flow temperature in AUTO heating mode.
TEMAX.
Outdoor temperature from which the water flow temperature will be TIMIN.
TEMIN.
Outdoor temperature below which the water flow temperature will be TIMAX.
