DAMPER SEQUENCES
Damper Zone (Zone Setup) dampers can not be used in conjunction with 4-pipe mode. Damper theory can
be shared between linked
ZON-0600
devices.
Single normally open (N/O) damper operation
In a no heat or no cool situation there is no power to any of the dampers so they all remain in an open state.
A call for heat or cool from a thermostat the corresponding zone output will not power as the damper is
already open, any other N/O dampers on this zone controller will power to close them if they are not calling.
If another zone damper calls as well the power to the corresponding zone output will be shut off, causing the
damper to open. Once the heat or cool demand is gone power is dropped to all dampers so that they will all
open. If there is a just a fan call or humidity all dampers remain open to allow ventilation/circulation.
Single normally closed (N/C) damper operation
In a no heat or no cool situation all of the dampers are powered so they all remain in an open state. A
call for heat or cool from a thermostat the corresponding zone output will remain powered and any other
dampers on the zone controller will power down thus closing them. If another zone damper calls as well the
corresponding zone output will be powered causing the damper to open. Once the heat or cool demand
is gone all dampers are powered so that they will all open. If there is a just a fan call or humidity all dampers
remain open to allow ventilation/circulation.
2 stage normally open (N/O) damper operation
Please note that whichever thermostat is set to 2 stage N/O they take over the next zone output, for example
the THM-1 is set to 2 stage N/O then the damper operates on the zone 2 output, also the THM-2 thermostat
output will switch off and if a thermostat is connected to this location it will power down.
