The user interface integrated in the indoor unit decides the space operation
mode. Mind that the operation mode on each room thermostat must be set to
match the indoor unit.

be connected to the indoor unit. The indoor unit will supply leaving water all the
time, with the possibility to program a leaving water schedule.
