Return temperature control
The return temperature is monitored so as to avoid, for example in summer mode, that if cooling is required and the
water that arrives at Vmix is hot heads are activated by heating the environment rather than cool it. A check is done
after verifying that a time from the opening of the parameter Vmix the return water temperature (in cold weather) is
not higher than the flow temperature setpoint active plus a delta parameter, in case of higher temperature will be the
Vmix closed and an alarm signaled the return temperature. Conversely for the heating mode, the return temperature
should not be lower than the flow temperature setpoint less active as a delta parameter.
