▪
For each room, a shut-off valve (field supplied) is installed to avoid leaving water
supply when there is no heating or cooling demand.
▪
A bypass valve must be installed to make water recirculation possible when all
shut-off valves are closed.
▪
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.
▪
The room thermostats are connected to the shut-off valves, but do NOT have to
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.
