7.3 Additional functionalities

SLAVE MODE
In case the SLAVE jumper (Fig.5.f - JP2) is short-circuited before powering the unit, the unit works in SLAVE MODE; the operating
speed is determined by the 1-10V signal received at the SLAVE input. All the operating logics described in the Mode selection
are ignored (paragraph 7.1).
FREE COOLING
The parameters "Desired Temperature", "Tmax Free Heating", "Tmin Free Cooling" (Menu 4 Bypass settings) are to be meant as
follows:
"Desired Temperature" is the ambient temperature desired by the user
"Tmax Free Heating" is the maximum outside temperature allowed for free heating operation
"Tmin Free Cooling" is the minimum outside temperature allowed for free cooling operation.
