Cooling in 2-pipe system
VVM 310 contains a built-in function for operating cooling
in a 2-pipe system down to 17 °C, factory setting 18 °C. This
requires that the outdoor module can perform cooling. (See
the Installer Manual for your air/water heat pump.) If the
outdoor module can perform cooling, the cooling menus are
activated in the display on the indoor module (VVM).
In order for operating mode “cooling” to be permitted, the
average temperature must be above the setting value for
“start cooling” in menu 4.9.2
The cooling settings for the climate system are adjusted in
the indoor climate menu, menu 1.
