Zonex 101PROG User manual

1/4 29/05/03 920-141-005-00-1-A
Thank you for choosing ZONEX SYSTEMS, we hope you will be
satisfied with your purchase.
The 101PROG is compatible with most 24 V single stage heating
and air-conditioning systems. The 101PROG offers two types of
temperature control: proportional adaptive and conventional. For
optimal comfort and maximum energy saving, the 101PROG
features a 7-day fully independant programmable schedule with
automatic changeover (from heat to cool and vice versa). An
optional remote telephone controller (CT240) can be connected to
the 101PROG, allowing users to control their system while away
from home.
Installation
nDisconnect power to your system.
Install the thermostat
For a new installation, choose a location about 5 feet above the
floor, with good air circulation. The thermostat must be installed on
an inside wall. Avoid locations where there are air drafts (top of a
staircase, air outlet,...), dead air spots (behind a door,...), direct
sunlight, concealed chimneys or stove pipes.
NOTE: Caution: If, upon removing an existing thermostat, you see
that it is mounted on a junction box (similar to the junction box
located behind an electrical switch or outlet), this may indicate that it
is a 120/240 V system. For safety, consult a qualified electrician to
check the installation.
Install and connect the thermostat
nRemove the screw holding the thermostat mounting plate.
oLift the lower part to separate the plate from the thermostat.
pMount the plate on the wall using the provided screws.
Identify the wires
nIf the wall plate of your old thermostat has more than two wires
coming out of the wall, you will need to label the wires. Start by
identifying the letters close to each screw or terminal on which
a wire is connected. These terminals may be located on either
side of the plate.
oDisconnect and identify each wire1.
pAttach and affix wires to the wall in order to prevent the wires
from falling back into the wall. If the wall cavity is larger than
necessary, fill with insulating wool in order to prevent the infil-
tration of warm or cold air behind the thermostat.

Thermostat Configuration (switches)
The 101PROG offers factory-set defaults. Before mounting the
thermostat, you may want to configure some of these settings. The
switches are located on the back of the front module.
Default settings are highlighted below.
Temperature Control (Switch # 5)
nProportional adaptive mode (P.I.A.)
This mode analyses previous cycles in order to define the length of
the up coming cycle. This operating mode guarantees optimal
regulation based on the capacity of your system. To avoid cycles
that are too short for the heating or air-conditioning units, minimum
On and Off duration is limited to 10% of the period (1.5 minutes for a
15 minute cycle). Ideal for: radiant or convection electrical heating
system, circulator control in a hot water system, electrical hot air
furnace, hot air, gas or fuel conventional furnace and air-
conditioning systems.
Not recommended for:
 Gas or fuel furnace or boiler with wall chimney, if they include a
combustion gas purging cycle exceeding 30 seconds. To verify
this point, check the duration of the delay between the heating
command sent by the thermostat and the moment when the
burner actually goes on.
 Multi-zone systems, where several thermostats command a
single heating or air-conditioning unit.
NOTE: In these two cases, conventional (deadband) mode is rec-
ommended.
oConventional mode with anticipation (deadband)
This mode commands the system's On and Off cycles when
the temperature read by the thermostat reaches pre-set levels.
This mode is compatible with all heating or air-conditioning
systems.
Temperature Control Cycles (Switches # 1 and # 2)
nProportional adaptive mode (P.I.A.)
In proportional adaptive mode, the 101PROG adapts the regulation
cycles to your system capacity. When cycles are very short, the
temperature variation in the room is very low and the comfort level
very high. However, very short cycles can generate premature wear
of your system. It is therefore important to adjust the cycles to your
type of installation. In general, the bigger your heating or air-
conditioning unit, the longer the cycles should be. The 101PROG
offers the possibility of programming regulation periods of 5, 10, 15
or 20 minutes using switches 1 and 2 at the back of the unit.
We recommend the following options:
oConventional mode with anticipation (deadband)
When the thermostat is in conventional mode with anticipation, it is
possible to program a span, that is temperature variations between
ON and OFF orders of your system. We recommend the following
configurations:
First Power-On
When you first install the batteries, the unit runs a
sequence of tests and a complete reset to zero,
which lasts approximately 5 seconds. The screen
should display 0:00 (blink), MO (day) and the current
temperature. If you are holding the thermostat in
your hands, the temperature could display higher. It
will return to normal about one hour after installation
on the wall plate.
Programming the time and day
 Set the time using the Hour and Minute
buttons.
 Set the day using the Day button.
Secure the thermostat to the wall plate as
indicated in the following diagram.

Operating modes
The 101PROG offers three operating modes:
Manual
This mode allows you to maintain a constant temperature.
 To activate, press Manual/Auto until is displayed.
 Set temperature OR press or to use a pre-defined
setpoint.
Automatic
This mode executes your programming.
 To activate, press Manual/Auto until is displayed. The pro-
gram number and corresponding setpoint are displayed.
Temporary Bypass
Maintains a specific temperature until the beginning of the next
program. Set the desired temperature OR press or
to use a pre-defined setpoint.
Vacation
Maintains a specific temperature when away for a prolonged
absence (e.g. vacation). Can also be done remotely through your
telephone using the optional CT-240 telephone controller.
 Press to activate.
Schedule Programming
The 101PROG allows 4 setting changes for each day of the week.
There are no pre-set programs; so you can adapt the schedule to fit
your life style. For each day, enter the time at which you wake up
(P1), the time you leave for work (P2), the time you come home (P3)
and the time you go to bed (P4).
NOTE: For temperature increases (Prog. 1 and 3), allow at least
10 minutes per °F. If you have lowered the temperature by 3 °F dur-
ing the night and you wake up at 7 AM, change the setting at
6:30 AM.
For savings to be obtained, you must lower the temperature for a
period of 2 to 3 times the delay required to bring the temperature
back to your comfort level.
Example: If your system takes one hour to go from your saving
temperature level to your comfort temperature level, it is useless to
lower the temperature for a period of 2 to 3 hours.
Program/Modify the Schedule

Heating, Air-conditioning or Automatic
Changeover Mode Selection
Use the Heat/Cool button to select one of the following modes:
To avoid needless switching, the automatic mode change will take
at least 2 minutes if it is required by a manual setting change and at
least 15 minutes if it is due to a quick temperature change.
Furthermore, to protect your heating and air-conditioning system, it
is impossible to shut down and restart the system within a period
equal to 10% of the cycle.
Fan Control
Use the Fan On/Auto button to force continuous air circulation
( ON) or to synchronize the fan with the heating or air-
conditioning demand ( AUTO).
NOTE: The AUTO mode is automatically selected when the thermo-
stat is in Vacation mode.
Telephone Controller
The 101PROG incorporates a remote input which allows connection
of a CT240 telephone controller. The CT240 provides remote
control of heating/air conditioning; switching from normal operating
mode to Vacation mode, and vice versa, using your telephone line.
NOTE: For complete details on
operating the telephone control-
ler, refer to the CT240’s Instruc-
tion Manual.
Connection to the CT240
Connect the CT240’s terminals
A and C to the thermostat’s
X and C respectively. You must
respect the polarity.
Connection to a house
automation system
The Vacation setting can also
be activated from a house
automation system.
Operating the telephone interface
You can activate the Vacation setting using the Vacation button of
the telephone controller or using the telephone itself.
nTo activate the Vacation setting, press the Vacation button of
the CT240. The Vacation setting will be displayed during
5 seconds and the icon will flash on the screen. You no longer
have access to the 101PROG keypad if this function is
activated by the telephone controller.
oTo deactivate the function and return to the previous mode,
press the Vacation button of the telephone controller again.
The red light will go off and the icon will disappear within a
maximum of 5 seconds.
Battery Replacement
NOTE: Even if the thermostat indicates
that the batteries are good, it is recom-
mended to replace them once a year, at
the beginning of the cold season.
The 101PROG will display the BATT
icon when batteries need to be replaced.
This icon will flash for 60 days. After this
delay, the thermostat will shut down
your heating/ac system. Data is kept for
15 sec. during replacement. Clock and programs are protected.
NOTE: Even if the thermostat indicates that the batteries are good,
it is recommended to replace them once a year.
