3. Locking the Set points:
To avoid unauthorized setpoint
modifications, the 101DIGI has
locking setpoint capability. After
the heat and cool setpoints have
been selected, use the jumper
located under the cover near
the middle of the board labeled
LCK to lock the setpoints. Slide
the jumper over both terminals
as shown in the diagram above.
This will lock the setpoints in
place. To modify the setpoints,
the jumper must be to moved to
the adjustable position.
DIGICOM:
The DIGICOM auto
changeover, communicating
thermostat is used exclusively in ZonexCommander thermal management
systems. Using a computer and the ZonexCommander software, all ther-
mostats in the system can be programmed and viewed. The DIGICOM
may be applied in stand alone unit control, from 1 to 80 split or pack-
aged systems. When used with a modem, all ZonexCommander software
functions can be controlled remotely. The DIGICOM requires 24V AC
power from either the zone system or HVAC unit transformer, with the
addition of a two conductor, twisted pair cable for communications.
Dimensions: 2-7/8” W x 4-1/2” H x 1” D.
101PROG:
Features a battery powered,
7-day programmable, auto changeover
control for single stage heating and cooling
applications. Thermostat can be programmed
for up to four periods per day, and offers
three operating modes: Manual, Automatic
and Vacation. Blower operation is manual
selectable for auto, on, or programmed for
fossil fuel or electric heat, fan cycling. The
oversized LCD display clearly shows the
time, day of the week, space temperature,
and selected operating mode. The 101PROG
also provides for mode control through an optional telephone controller.
Dimensions are 3.75”W x 5”H x 1”D. Color: White.
ZONE THERMOSTATS – COMPATIBILITY
The 101ASSB gas/electric and 101AACBHP heat pump controllers are
compatible with most thermostats, offering a wide thermostat selection
to the installing contractor. NOTE: the 101AACBHP pump controller
utilizes gas/electric thermostats. When using other than Zonex
Systems thermostats, please refer to the following guidelines:
Electronic Thermostats:
Digital thermostats requiring 24V AC power
must be “Hard wired” with a separate R and C or common terminal.
Power robbing type thermostats are not compatible. All types of battery
operated thermostats may be used with any System 2000 control system.
Mechanical Thermostats:
When using a mechanical thermostat,
ensure the cooling compensator (anticipator) is removed, and the
heating anticipator is shorted or set to its lowest setting.
Please contact Factory Technical Support for additional thermostat
compatibility information.
ZONE THERMOSTATS
The Zonex Systems digital thermostats can be ordered with a remote sen-
sor. Remote sensors are useful if you would like to place the thermostat
and sensor in different locations. Simply add “RS” at the end of the part
number to order with a remote sensor; i.e.: “101DIGIRS”.
Wiring:
The remote sensor must be wired with a minimum 18 ga., two
conductor shielded cable, with a maximum length of 200 feet. The wires
have no polarity. Use field supplied wire nuts to connect the sensor. Flare
back and tape off the cable shield closest to the sensor. Connect the
shield at the thermostat to the “R” terminal.
