MODEL TH101A

INSTALLATION

This thermostat has been designed to operate with any installation which has
a resistive load (not exceeding 4000W / 240Vac or 2000W / 120Vac) such as
electric baseboards, radiant ceilings and floors, electric convectors, etc. IT IS
NOT COMPATIBLE WITH A LOW VOLTAGE CONTROLLER USED BY A
CENTRAL HEATING SYSTEM.

Electricians or experienced technicians should install the thermostat.

This thermostat is designed to be used with a self -protected heating system
equiped with a circuit breaker.

If you have any questions concerning the installation or programming of the
thermostat, please call our technical assistance at [phone] for
Montreal area or 1-800-831-AUBE for outside area, between 8:30 AM and 5:00
PM, Monday to Friday, Montreal eastern time, Canada.

TURN OFF POWER TO HEATING SYSTEM AT THE MAIN POWER PANEL
TO AVOID ELECTRICAL SHOCK. Keep air vents of thermostat clean and
free from obstructions.

1) What kind of heating system do you have ?

The thermostat has been
factory set to proportio­nally control electric base­boards, radiant systems
and convectors. Since
proportionnal control uses
a fast commutation rate
(120/min) it is not
compatible with fan
equipped systems.

You can change the
control mode to make it
compatible with fan
equipped convectors. In
that case, slide switch #1
(SW1) located on the
back of the thermostat at
position « ON », than
press on the « reset » button by using a fine probe.

2) Mounting thermostat wallplate

Wallplate is used when the thermostat is to be mounted close to a door frame
or any other obstacle. It is also useful to level the thermostat.

Secure the wallplate to the electrical box using 6-32, 1/2" screws. See above
drawing.

3) Connecting wires and mounting thermostat

Connect the rear thermostat wires to the power supply and to the electric
heater wires using solderless connectors for copper wires. See schematic

diagram.
Push the exces s wire back into the electrical box to prevent interference with

CHARACTERISTICS

Operation modes

The thermostat has four (4) operation modes :
AUTO, MAN, STBY AND OFF.
They are selected through the MODE button. On display, the active

mode is framed. The frame moves on to the next mode each time
the MODE button is pressed.

NOTES :

When scrolling from the operation mode OFF to an active mode, the
thermostat will take 5 to 10 seconds to display the room temperature.

In normal use, the thermostat housing temperature can reach 35 °C to
45 °C.

AUTO

If you leave your home for the weekend and you wish to keep the
temperature to an economic level, instead of adjusting the
thermostat in manual mode and changing the setpoint of all units,
just set the thermostat in STBY mode.

In this mode, the electric heating system is turned off. Only the
time and the operation OFF mode framed are displayed.

The AUTOmatic mode
executes in sequence (hourly)
the programs recorded by the
user.

Pressing on the t or s button
displays the temperature
setting for five (5)econds.

The MAN operation mode
allows the user to bypass the
programming and holds the
present temperature.

The first time the t or s button
is pressed, the temperature
setting is displayed. For all
subsequent times pressed, the
temperature setting will change
1°C.

The STBY ( STANDBY) mode
allows an immediate adjustment
of the temperature setting. It is
factory set to 10 °C. User can
modify by refering to section:
PROGRAMMING TH E STBY
MODE TEMPERATURE.

A pressure on the t or s button
displays the temperature
setting for five (5) seconds.

Why should you use the STBY
mode?

1) Proportional control

This thermostat works differently than the conventional
electro-mechanic one. The latter can have a variation of the set
temperature up to 4 °C while the electronic thermostat has a
variatio n of only 0.3° C. This slight oscillation eliminates the
discomfort of temperature variation often found with conventional
electro-mechanic thermostat.
The proportional controller determines the amount of power required
by the electric heating system to maintain the exact ambient
temperature of the temperature setting.

The display shows, in real
time, the applied power to the
electric heating system.

If you have set the switch #1
at position « ON » to control
a fan equipped system, the
display will show 100 % when
the heating system is turning
on and 0 % when it is OFF. In
that case, the temperature
regulation is +/ - 0.5°C around
the set point.
