temperature control
APPLICATION DEVICES
A My Home temperature control system can manage
up to 99 zones. The system is on a 2-wire bus and
made up of the following devices:
Temperature control unit:
this confi gures the system, customises the programs
and displays information.
Sensors:
at least one sensor must be installed in every zone.
They measure the room temperature and can locally
vary the temperature set on the control unit.
Actuators:
operate the solenoid valves and the circulation
pumps. The number and type of actuators are chosen
depending on the type of solenoid valves installed and
their location in the system.
Just one contact is used to control the ON/OFF solenoid
valves, while the two-relay interlock is used for the
open/close solenoid valves. The four-relay actuator
controls the fan-coils and also automatically controls
the 3 speeds.
The ideal system solution is to have the solenoid
valves grouped on the collector, so that a board
can be made containing the actuators near the
box.
This makes wiring simpler with a small number of
actuators.
