5.1.1 Standby
5.1.2 Lock – Unlock
5.1.3 Heating – Cooling
Attention: Note in standby only the antifreeze function is alive.
When the thermostat is connected to a wiring centre, only one device (thermostat or wiring centre) can switch the system
from heating to cooling and then from cooling to heating. If you try from a thermostat to switch from cooling to heating
mode and the thermostat displays NO, it means that it is possible switch in cooling mode only from the device (thermostat
or wiring centre) that switched the system from heating to cooling.
Note: If in the thermostat the Cooling function (User menu 03 COL) is disabled, it is no possible to switch in cooling mode, if
you try the heating icon blinks.
