mode. Mind that the operation mode on each room thermostat must be set to
match the outdoor unit.
▪ The room thermostats are connected to the shut-off valves. They are also
connected to the outdoor unit (X2M/35 and X2M/30) -via a relay (field supplied)-
to give feedback when operation is needed. The outdoor unit will supply leaving
water as soon as there is a request from one of the rooms.
