Multi-Zone Systems
PSMZ-100/200 for Multi-Zone System
24VAC, Controller for multi-zone system
controlling 4 to 7 zones
The PS-MZ 100/200 is ideal for residential, commercial or
industrial applications. It is compatible with Heat/Cool or
Heat Pump HVAC applications and can control up to 4
(PS-MZ100) or 7 (PS-MZ200) different zones.
One of the zones serves also as the master, and different
types of thermostats can be selected as masters or zones.
Zones can also be programmed for on/off, ideal for times
when the zone is less occupied.
The main board offers inputs for Bypass and Fresh Air
dampers and 3 different temperature sensors. Other
features such as Auto-Changeover mode and quick
connectors from the thermostats to the main board, make
this multi-zone the simplest and most efficient climate
control system.
