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)
n
Proportional 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.
o
Conventional 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)
n
Proportional 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:
o
Conventional 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.

This function determines whether the heating system fan is operated by the
thermostat or by the plenum's temperature of the heating unit. In general, the fan is
operated by the heating unit. However, if the fan does not turn on and the
thermostat requires heating for more than one minute, push #6 switch up.
