INSTALLATION
Note: The "Problems and Solutions" section at the end of this user's guide
will help you to correct your problems during the installation.
This thermostat has been designed to operate with any installation which has a
RESISTIVE load not exceeding 2500 W @ 240 VAC or 1250 W @ 120 VAC 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 or
systems using a contactor or a relay whose current is under 1.0 A.
Electricians or experienced technicians should install the thermostat.
This thermostat is designed to be used with a self-protected heating system
equipped with thermal cut off and circuit breaker.
PARTS INCLUDED
- One (1) TH102D thermostat
- Two (2) 6-32 screws, 1 ½ inches
- Two (2) solderless connectors
TURN OFF POWER OF THE HEATING SYSTEM AT THE MAIN POWER
PANEL TO AVOID ELECTRICAL SHOCK. Keep air vents of thermostat clean
and free from obstructions.
1) 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 (there is no polarity for the
wires). See schematic diagram.

NOTE: To access the programmable keyboard, remove the cover by placing
your fingers to the right side of the thermostat and pull toward you.
Push the excess wire back into the electrical box to prevent interference with the
thermostat. Secure the thermostat using the supplied screw. Once the thermostat
is properly installed, return power to heating system.
Note 1 : All cables and connections must conform to the local electrical
code.
Note 2 : In normal use at full capacity (2500 W), the housing temperature of
the thermostat can reach 35 to 40 °C.
WARNING : Special CO/ALR solderless connectors must be used when
connecting with aluminum conductors.
2) Options selection
Some options have been factory set. Those default settings are :
• The temperature is in °C, the heating control is proportional and the time
format is 24 hrs.
2.1 Temperature displayed in °C or °F
To change the temperature from °C to °F and back, maintain DAYbutton pressed
down as RESET button is being pressed on and released. Then release DAY button.
2.2 Time format displayed in 24 hours or 12 hours
To change the time format from 24 hrs. to 12 hrs. and back, maintain HOUR button pressed down as RESET button is being pressed on and released. Then
release HOUR button.

2.3 Proportional or ON/OFF heating control
This thermostat has been factory set to proportionally control electric
baseboards, radiant systems and convectors. Since proportional control uses a
fast commutation rate, it is not compatible with fan equipped systems (see
characteristics). Also, this control mode could occasionally create light flickering,
especially in rural area.
You can change the control mode to make it compatible with fan equipped
systems or to eliminate the light flickering.
To do so, maintain MIN button pressed down as RESET button is being pressed
on and released. Then release MIN button. Following this operation, the display
will show the fan indicator. To return to proportional control, repeat the same
operation.
3) Memory backup
In the event of a power failure, an internal circuit will maintain the programming.
The display will stay on for 15 minutes. An indicator "LP" will be shown on the
display. Beyond this period, the display will turn off. Only the time will have to be
set if power failure is more than six hours. The thermostat will return to the same
operation mode as set before the power failure.
4) First power-up
When power is applied for the first time, the
display must show the day and hour as follows:
0:00 MO (Monday)
The active operation mode is the framed MAN mode, the
temperature setpoint is 20 °C and the ambiant
temperature is displayed.
If the display is different, maintain PGM button pressed
down as RESET button is being pressed and released.
Then release PGM button.
500 WATTS OR LESS INSTALLATION
During the 30 minute period following the installation or a long power failure
(more than 6 hours), the light intensity of the display decreases when a button is
pressed on while the thermostat is in the heat mode. This problem will disappear
when the accumulator for the memory backup will be charged.
OPERATING MODES
The TH102D thermostat has three (3) operating modes:
AUTO, MAN and ECONO.
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 on.
The AUTOmatic mode runs in sequence (hourly) the
programs recorded by the user.
Pressing on the or displays the temperature
setting and the SETPOINT indicator for five (5)
seconds.
To see the weekday and weekend programs, select the
AUTO mode and press successively on PGM button to
see the programs appear on the display.
The MAN mode allows the user to override the
programming.
The first time the or is pressed on, the temperature setting is displayed. For all subsequent times
pressed on, the temperature setting will change 1 °C.
The ECONO mode has two (2) programs in which the
day, the time and the setpoint has to be programmed. For
instance, this operating mode can be used for a cottage
installation where the user goes only on weekends.
Program 1: Friday 3:00 PM, 20 °C
Program 2: Friday 8:00 PM, 15 °C
The temperature will be maintained at 20 °C Friday from
3:00 PM to 8:00 PM, and maintained at 15 °C the rest of
the week.
This gives you a comfortable temperature at your arrival
and if you are not going to your cottage for the weekend,
there will be only a minimal heating period.
To see the ECONO programs, select the ECONO
operating mode and press on PGM button successively
to see programs 1 and 2 appear on the display. In
ECONO mode, pressing on the or displays the
temperature setting.
PROGRAMMING
1) Adjustment of time and day
Example of setting: Thursday 8:15 AM
Use DAY, HOUR and MIN buttons to set the
time.
Once set, press on RET button to exit the time
and day adjustment mode
Note 1 : Time indicator is showing you that the time must be set.
Note 2 : The thermostat has an automatic return. When such functions as
time recording, programs recording, etc., are not completed by
pressing on RET button, the thermostat will automatically exit the
mode after 60 seconds.
2) Typical suggested programs
