Parameter setting

For the regulator to be able to recognize this installation you need to
set the following parameters as shown in the table.
LOW–TEMPERATURE ZONE:
mixing valve, pump, zone feeler and room unit
Installation ID
– Setting mode = USER
(refer to the "Parameter setting levels" paragraph)
Par Description
17* Heating curve slope
* According to the installation type
– Setting mode = INSTALLER
(refer to the "Parameter setting levels" paragraph)
Par Description
69* Max. limit of delivery temp. setpoint
96 Input H1
* According to the installation type
NOTE 1: The thermostat for excess temperature has the purpose of
stopping the production of heat in case the water temperature gets
too high and damages the floor. We recommend setting at 45°C.
NOTE 2: When a zone thermostat is required the AUTO led is
blinking. This doesn't therefore indicate a failure.
