BEFORE YOU BEGIN
Loss of Control
WARNING
LOSS OF CONTROL
•Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
•The designer of any control scheme must consider the potential failure modes of control
paths and, for certain critical control functions, provide a means to achieve a safe state
during and after a path failure. Examples of critical control functions are emergency stop
and over travel stop.
•Separate or redundant control paths must be provided for critical control functions.
•System control paths may include communication links. Consideration must be given to the
implications of anticipated transmission delays or failures of the link.1
•Each implementation of equipment utilizing communication links must be individually and
thoroughly tested for proper operation before being placed into service.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
California Proposition 65
WARNING
CALIFORNIA PROPOSITION 65
This product can expose you to chemicals including Lead and Bisphenol A (BPA), which are
known to the State of California to cause cancer and birth defects or other reproductive harm.
For more information, go to www.P65Warnings.ca.gov.
Failure to follow these instructions can result in birth defects or other reproductive
harm.
Electrostatic Discharge
NOTICE
STATIC SENSITIVE COMPONENTS
Circuit boards and option cards can be damaged by static electricity. Observe the electrostatic
precautions below when handling controller circuit boards or testing components.
Failure to follow these instructions can result in equipment damage.
Observe the following precautions for handling static-sensitive components:
•Keep static-producing material such as plastic, upholstery, and carpeting out of the
immediate work area.
•Store static-sensitive components in protective packaging when they are not installed in
the drive.
•When handling a static-sensitive component, wear a conductive wrist strap connected
to the component or drive through a minimum of 1 megohm resistance.
•Avoid touching exposed conductors and components leads with skin or clothing.
1For additional information about anticipated transmission delays or failures of the link, refer to NEMA ICS 1.1 (latest edition),
Safety Guidelines for the Application, Installation and Maintenance of Solid State Control or its equivalent.

Installation
NOTICE
INSTALLATION
•The system must be installed correctly by a qualified technician.
•If replacing an existing Room Controller, label wires before removal of Controller.
•Electronic controls are static sensitive devices. Discharge yourself correctly before
manipulating and installing Room Controller.
•A short circuit or wrong wiring may permanently damage Room Controller or equipment.
•All Room Controllers are designed for use as operating controls only and are not safety
devices. These instruments have undergone rigorous tests and verification prior to shipping
to ensure proper and reliable operation in the field. Whenever a control failure could lead to
personal injury and/or loss of property, it becomes the responsibility of the
user/installer/electrical system designer to incorporate safety devices (such as relays, flow
switch, thermal protections, etc.) and/or an alarm system to protect the entire system
against such catastrophic failures. Tampering with the devices or unintended application of
the devices will result in a void of warranty.
•This device must be installed to provide a separation distance of at least 8in (20cm) from all
persons and must not be located or operating in conjunction with any other antenna or
transmitter.
•Refer to the Room Controller User Interface Guide for information on how to configure the
Room Controller.
Failure to follow these instructions can result in equipment damage.

according to the supplier documentation.
Failure to follow these instructions can result in equipment damage.
Cleaning the Room Controller
NOTICE
CLEANING THE ROOM CONTROLLER
•Use a soft, pre-moistened lint-free cloth for cleaning.
•Avoid getting moisture in openings.
•Do not spray anything directly on the Room Controller or use compressed air.
•Do not use caustic/corrosive products, ammonia, solvents or any cleaning product
containing alcohol or grit.

THEORY OF OPERATION
The VZ765 series uses a Viconics proprietary adaptive logic algorithm to control the space
temperature. This algorithm controls the heating and or air conditioning system to
minimize overshoot while still providing comfort. It provides exceptional accuracy due to its
unique PI time proportioning control algorithm, which virtually eliminates temperature
offset associated with traditional, differential-based on/off thermostats.

Heat pump model specific features
•Selectable single or dual stage compressor stages
•High balance point:
•Locks out auxiliary heating when outside air temperature is above this value.
•Low balance point:
Locks out heat pump compressor operation when outside air temperature is below
this value.
•Compressor/auxiliary interlock:
Adds flexibility by locking out heat pump operation during auxiliary heating, to prevent
high pressure trip when the coil is downstream of the auxiliary heat source.

WIRELESS SYSTEM OVERVIEW
Viconics VZ72605x00W Zone Controllers are used in conjunction with the
VZ7656x1000W roof top controllers. Combined, they are designed for operating typical;
single or multistage RTU’s and their associated local zones. For example, a typical job
layout system may feature 3 RTU controllers and a total of 31 zones. This would bring to
total number of nodes (individual Com addresses) to 34. RTU 1 would have 10 zones
under its command, RTU 2 would have 10 zones under its command and RTU 3 would
have 11 zones under its command.

TYPICAL APPLICATIONS
Main outputs wiring
Wiring notes:
Note 1: If the same power source is used for the heating stages, install jumper across RC &
RH. Maximum current is 2.0 amps.
Note 2: If auxiliary output is used to toggle occupancy of the electronic control card inside
the equipment, configure the relay parameter (Aux cont) to the N.O. setting. A
second relay can be added for additional functionality of the occupancy output.
Note 3: Analog outputs and inputs use a half bridge rectifier. Reference of the control signal
is the common of the power supply of the Terminal Equipment Controller. (Terminal
C)
Note 4: Electromechanical contacts are to be used with the digital inputs. Electronic triacs
cannot be used as mean of switching for the input. The switched leg to the input for
the input to activate is terminal C (common)
Note 5: The transformer of the unit provides power to the t Terminal Equipment Controller
and the additional loads that will be wired to the Terminal Equipment Controller.

CONFIGURING AND STATUS DISPLAY INSTRUCTIONS
Status display
The Terminal Equipment Controller features a two-line, eight-character display. There is a
low level backlight that is always active and can only be seen at night.
When left unattended, the Terminal Equipment Controller has an auto scrolling display
that shows the current status of the system.
Each item is scrolled sequentially with the back light in low level mode. Pressing any key
will cause the back light to come on to high level.
Manual scrolling of each menu item is achieved by pressing the Yes (scroll) key
repetitively. The last item viewed will be shown on the display for 30 seconds before
returning to automatic scrolling. Temperature is automatically updated when scrolling is
held.
