· Changes via the local HMI or via tool have the same priority (last always wins)
· Setting the Comfort basic setpoint will reset the runtime Comfort setpoint to the
basic setpoint
· The resulting (current) setpoint heating and cooling is limited by the Protection
setpoint; if Protection setpoint is OFF, then minimum 5 °C and maximum 40 °C
are used
· The resulting setpoints for cooling and heating of the same operating mode have
a minimum distance of 0.5 K between them
3.4 Applications overview
