This standard 2000 series 4 Gang Switch base accommodates a Two Zone Manual
Zone Control that will allow either zone to be selected with sensing in the
selected zone, or both zones, in which case the two sensors will be averaged
and both zone dampers will be open.
It is not possible to turn both zones off.
If attempted, a zone will be selected as default. Dampers can be spring
return or driven both ways, and are 240 VAC or DC. Also, a system on/off
switch is provided, as well as day/night setpoints switch.
