Damper Module(s)
The Damper Module is designed to operate with 24VAC
2-wire and 3-wire zone dampers.
The Damper Module(s) must be hardwired with 24VAC
connected to R and C.
The zone damper will be connected to the NC, C, and
NO terminals on the left side of the subbase.
The Master Thermostat will transmit the required
damper position to the Damper Modules.
When the damper position is open, the ZONE
LED will be flashing. 24VAC will be supplied to
NC and C terminals.
When the damper position is closed, the
ZONE LED will be solid. 24VAC will be
supplied to NO and C terminals.
Wire the terminals according to
the damper type used.
