An example of dividing the heating system into zones is shown in the figure
below:
From both a comfort and an energy-efficiency point of view, it is recommended
to activate more than one switch for each day. Furthermore, it is advised that a
comfort temperature is used only those times, when the room or building is in
use, since every 1 °C decrease of temperature saves approxi mately 6% energy
during a heating season.
2. THE CONNECTION POINTS OF THE ZONE CONTROLLER,
MOST IMPORTANT TECHNICAL DATA
•
Each of the 4 heating zones have an associated pair of connection
points (T1; T2; T3; T4); one for a room thermostat and one for a zone
valve/pump (Z1; Z2; Z3; Z4).
The thermostat of the 1st zone (
T1
) controls
the zone valve/pump of the 1st zone (
Z1
), the thermostat of the 2nd zone
(
T2
) controls the zone valve/pump of the 2nd zone (
Z2
) etc.
Following
the
heating
command of the thermostats, 230 V AC voltage appears on the
connection points of the zone valves associated with the thermostats
,
and the zone valves/pumps connected to these connection points open/start.
For ease of use, the connection points associated with the same zone have
the same color (T1-Z1; T2-Z2, etc.).
