For years, DZ was able to control modulating dampers.
It seems, however, that bang-bang dampers still have their place, hence, SwitchDamper was added to Subversion and will become a part of the next release.
Now you can use DZ to control any HVAC actuator that is controlled by a switch. This includes, in particular, but not limited to:
- existing open/close dampers normally controlled by 24VAC;
- electric heaters that are configured as auxiliary heaters in a complex zoned system;
- hydronic, geothermal and steam system valves.
