This parameter allows you to activate the "antilegionella" function as described in paragraph "4.7 Anti-legionella function (only if connected to a storage cylinder with probe
501
and OT + connection not present)". The factory setting of this parameter is 0 (function disabled). Set the value to 1 to activate the weekly antilegionella function, the is
carried out the third day of the week at 03:00 am. Set the value to 2 to activate the daily antilegionella function, the is carried out every day of the week at 03:00 am.
502
This parameter indicates the delay in hours with respect to the fi rst time the anti-legionella function is followed
503
Is the boiler fl ow temperature when the anti-legionella function is active.
504
The water tank charging request is activated when the temperature measured by the water tank probe is lower than the water tank setpoint - par. 504.
505
The water tank charging request is deactivated when the temperature measured by the water tank probe is greater than the water tank setpoint + par. 505.
506
Parameter for setting the boiler delivery temperature to the domestic hot water tank
This parameter allows you to activate the SLIDING OUTLET function to modify the delivery setpoint used by the boiler, when there is a domestic hot water request (only
507
when a water tank with a probe is connected, C case). The factory setting for this parameter is 0 (function deactivated), set the parameter to 1 to activate the function.
See paragraph "4.6 Sliding delivery (only if water tank connected)" for more details.
508
To set the minimum DHW setpoint
509
To set the maximum DHW setpoint
512
This value can be used to enable/disable the DHW post-circulation function with inhibition of heating start-up.
513
This value sets the duration of the DHW post-circulation when the DHW post-circulation function with inhibition of heating start-up is enabled.
701
Used to activate the storage of an alarm history. Default 0; the value automatically changes to 1 after 2 hours of operation
This parameter allows periodic control of the boiler according to an operating period set in parameter 707.
There are three setting values:
0 = function disabled
1 = function enabled according to the following rule:
if 707 <4 the display shows the CFS signal
if 707 = 0 the display shows the SFS (STOP FOR SERVICE) signal which indicates the permanent inhibition of all requests for heating and domestic hot water.
706
Not resettable
2 = function enabled:
when 707 = 0 the display shows the CFS signal without any stop of operation
In this condition, the INFO menu (line I044) displays the number of days that have passed since the CFS signal appeared (707 = 0)
b
The CFS signal occurs at 10 min intervals for the duration of 1 min, 1 month before the end of the period set in parameter 707.
707
Fixed operating period for the service call (parameter 706) .
801
FUNCTION NOT AVAILABLE ON THIS MODEL
This parameter is used to enable the remote control of the boiler via an OpenTherm device:
0 = OT+ function disabled (remote boiler control via an OT+ device is not possible). If this parameter is set at 0, the OT+ connection (if present) will be immediately
803
interrupted
1 = FACTORY VALUE. OT+ function enabled (an OT+ device can be connected for remote boiler control). When an OT+ device is connected to the boiler, the message
"Ot" appears on the display.
