SUBZONE OVERVIEW
The system is designed for over-conditioned areas and prevents over-heating and over-cooling of individual or
stand alone zones. The SubZone is a battery powered auto changeover programmable thermostat that
communicates via an RF wireless signal to a damper control module located on a fully modulating round or
rectangular damper or D-Fuser.
Auto changeover operation allows the SubZone thermostat to change from a cooling to a heating thermostat
automatically. A duct sensor is included and installed upstream of the damper to determine the temperature
in the duct. If the SubZone thermostat is calling for cooling and cool air is available in the duct the damper
will modulate open. A heating call will close the damper. If the sensor determines warm air is available in the
duct and the thermostat is calling for heat the damper will modulate open. The SubZone system senses the
duct temperature and compares it to the set point vs. room temperature providing warm or cool air as
required. If the thermostat is not calling for heating or cooling the damper will modulate to 40% for
ventilation.
The SubZone allows you to effectively control problem areas by controlling the existing air supply to the
problem room or zone. This versatile problem solver is also designed to control supplemental or
auxiliary heating devices.
Zonex auto changeover programmable thermostat is designed to control and modulate a stand alone diffuser or damper.
Zonex offers 600 unique sizes of round and rectangular dampers for your commercial applications.

INSTALLATION
1. Install Wireless SubZone Round, Rectangular or D-FUSER Damper into the supply air duct.
(Ref. Part # WST Round, WCD Rectangular WxH, WD-FUSER)
2. Install a 24 volt, 40 VA transformer in accordance with local code requirements. From the transformer - run 18/2 wire and
connect to SubZone control board terminals R and C.
3. Install Discharge Air Sensor (TS) in the ductwork prior to the supply damper and run sensor wires to the SubZone control
board. If wires need to be extended, 18 gauge thermostat wire may be used, not to exceed 100 ft. in length.
4. Duct Air Temperature (TS) sensor wires are connected to the TS terminals of the SubZone control board.
Once the SubZone damper with controller has been installed go to Programming and Setup Instructions on the next page.
*NOTE: An air proving switch (field supplied) must be used for reheat applications. A field supplied relay may be required for VAV box
applications.

The SubZone Wireless Thermostat communicates with SubZone Damper Controller every minute or each time the thermostat
buttons are pushed, transmitting information between the SubZone Damper Controller and the SubZone Wireless
Thermostat. System logic dictates system mode of operation. When duct temperature is 3 degrees or more below room
displayed temperature on SubZone Wireless Thermostat, the mode is set as Cool. When duct temperature is 7 degrees or
greater than room temperature as displayed on SubZone Wireless Thermostat, then mode is set for Heat. If duct temperature
is neither 3 degrees below nor 7 degrees above room temperature displayed on SubZone Wireless Thermostat, then mode is
set for Vent.

battery life and damper will go to ventilation mode, 40%
open. When it comes out of Unoccupied Mode to Occupied
Mode at established setup time it will resume normal
operation.
To wake the SubZone thermostat when in Unoccupied
Mode, press any button to override.
TURN OFF SUBZONE
To turn SubZone Wireless Thermostat “OFF”, press and hold

SETUP INSTRUCTIONS
BATTERY INSTALLATION/REPLACEMENT
The SubZone Wireless Thermostat requires two AA batteries. When the battery ICON on SubZone wireless controller
indicates batteries are low, replacement of batteries is required. To access batteries, locate SubZone Wireless Thermostat set
screw on the bottom of the thermostat. Turn screw clockwise - this will cause the screw to move into stat sub-base. Once set
screw is free of SubZone stat, remove stat from sub-base. Remove batteries from the back of thermostat and insert
replacement batteries; insuring positive and negative poles match battery to thermostat. Place thermostat on sub-base and
turn set screw counter clockwise to fasten thermostat to sub-base. Reset time on the SubZone after battery replacement.
BOTTOM
With a 5/64 Allen wrench unscrew CW to release
the thermostat from the mounting plate.
MOUNTING THE SUBZONE
Once you have determined where you want to place the
thermostat place the mounting plate in that spot and with
a pencil mark where the drill holes will be. Drill holes
using a 1/8 drill bit. Install screw anchors supplied with
the thermostat. Install the screws into the screw anchors
half way and place the mounting plate over the screws.
Once the mounting plate is level tighten the screws down
to secure the plate to the wall. Install the thermostat back
on the mounting plate and turn the Allen screw CCW to
secure the thermostat back to the plate.
