Duct Pressure Sensor (Model PS2)
Vacant Operation
The Duct Pressure sensor (PS2) is installed in the main supply
duct, at least 3 feet before the first split and is connected to the
panel.
The two VAC terminals at the Zone1 thermostat can be
connected to a switch or timer. When activated by the switch or
timer, all of the zones are joined and respond to the Zone1
thermostat. When the occupant leaves the home, they can set
the switch to Vacant and only set the Zone1 thermostat.
Installing the Duct Pressure Sensor
Drill a 3/8-inch diameter hole in the supply duct (7) and thread
the pressure pickup (6) into the hole. Use a small amount of
sealant if required. Attach the pressure tube (3) to the pressure
pickup (6).
Remove the screw (1) and slide the cover (2) up the pressure
tube (3). Use the two screws (4) to attach the pressure sensor
base (5) to the duct (7). Using 3-conductor thermostat wire,
connect the red, white and green thermostat wires to the
terminals. Slide the cover over the base and secure the screw.
