7.3 Additional functionalities
SLAVE MODE
In case the SLAVE jumper (Fig. 5.g - 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).
BYPASS
The QR590E is equipped with a physical bypass which allows to mitigate the heat exchange when the indoor and outdoor
temperature combinations are such that the heat exchange is not recommended. In this case the Bypass icon
on the LCD.
The parameters "Desired Temperature", "Tmax Free Heating", "Tmin Free Cooling" (Installer Menu 4) 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.

mode at speed 1 (DEFAULT condition).
ANTI-FROST
Intake Fan speed is reduced during very cold weather in order to prevent ice inside the unit which could damage the heat
exchanger.
In this case the ANTI-FROST icon
