4 = Enable automatic changeover based on the average of DT between the temperature measured and the set point on each
master e-drofan that is ON and without alarms.
Select only if the following conditions are true at the same time:
• En02=0: 2-pipe system
• En01=1: µC
2
SE connected
• Chiller with heat pump or En03=1 (boiler available).
Minimum average DT to enable the action: Ch02.
Minimum time between one action and the next: Ch03.
Ch02 Temperature differential for automatic changeover (only Ch01 = 2 or Ch01 = 4). 3 1 20 C°
Ch03 Minimum time between:
• successive activations/deactivations of external heating or cooling unit for Energy Saving (Ch01 = 1)
• successive automatic changeovers (Ch01 = 2, 3, 4)

Co01 Activation and logic for outlet water temperature set point compensation, chiller/hp
0 = disabled
1 = Compensation based on the sum of the differences, with sign, between the temperatures read by the e-drofan
probes and the corresponding set points (only for the master e-drofan units that are ON and without alarms, and that are
working in the same mode as the chiller/hp); the sum is divded by the sum of all the master e-drofan units that are ON and
without alarms.

2 = Compensation based on the difference, with sign, between the temperatures read by the µAM probe and its set point.
The set points on all the e-drofan units are updated every minute with the value of the µAM set point.

SE available
When the µC 2 SE is not installed or is not connected to the RS485 data line, the µAM can still control the e-drofan units.
0=absent
1=available
Note:
• Based on the settings of Ch01, En01, En02, En03, some operating modes for the µAM, e-drofan and µC
2
SE may not be avail-
able; see the “Summary table of operating modes” (Table 6.3)
• Setting this parameter restarts the automatic detection of the connected devices (see paragraph “Configuring the µAM - Func-
tions to be activated during installation”).
• when En01=0 the OCh and ACh alarms are not displayed.
