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.
Push the exces s wire back into the electrical box to prevent interference with
the thermostat. Fix the thermostat using two (2) 6-32 screws 1 3/4 inches
long. Once the thermostat is properly installed, return power to heating
system.
All cables and connections must conform to the local
electrical code.
In normal use, the thermostat's housing temperature can
reach 35 to 45 °C.
Special service CO/ALR solderless connectors must be
used when connecting with aluminium controlers.
4) Batteries
Your thermostat is provided
with two (2) back-up batteries.
Those batteries will protect the
clock and your programs
against power failure. Batteries
are used only during power
failure and provide 500 hrs of
protection.
To install the back-up batteries, press the latch on the battery
compartment and lift off the cover. Insert the batteries and respect
the polarity. Replace the cover.
To check batteries condition,
press BATT key. The display

OPERATION
CHARACTERISTICS
Operation modes
1) Proportional control
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
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.
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.
2) Characteristics
- Model: TH101A
- Electronic Programmable line voltage thermostat (2 wires).
MAN
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.
- Supply: 120/240 VAC, 50/60 Hz.
- Load: 16.6 Amp. maximum, 1.8 Amp minimum (Resistive only).
- Power: 4000 W / 240 VAC or 2000 W / 120 VAC.
- Power consumption (off) : 860mW.
- Approvals: CSA
- Display range: 0 to 40 °C (32 to 99 °F )
- Setting range: 5 to 35 °C (41 to 95 °F )
- Storage: -20 to 50 °C (-4 to 120 °F )
- Temperature control: 0.3 °C (SW1=Off), +/- 0.5 °C (SW1=On).
- Precision: ± 0.5°C (2500W), 0.9°C (4000W) of temperature setting.
STBY
- Six (6) programs: 4 weekday programs and 2 weekend programs.
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.
OFF
Why should you use the STBY
mode?
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.
