Example
with two Multizoner wiring centres
The
ground floor MZ I controls the ground floor underfloor pump, the motorised valve
for the ground floor heating and the actuators at the manifold for each room circuit.
It switches the boiler when required by any circuit. It also time controls the
bronze pump
on the cylinder if fitted.
The first floor
MZ II controls the underfloor heating pump, the first floor heating motorised
valve and the actuators for each room heating circuit on this floor. It also switches
the boiler when any heating circuit requires it.
Example
with one Multizoner wiring centre
MZ I controls the underfloor heating pump and the actuators at the manifold. It also operates the motorised valves for each floor and switches the boiler on when required by any heating circuit.
In both examples MZ I closes the motorised valves for the heating circuits when the cylinder thermostat is calling for hot water heating. This is known as hot water heating priority and avoids over sizing boilers in modern systems.
