INSTALLATION
This thermostat is designed to use a floor-heating sensor to regulate room
temperature.
The TH132-AF has two temperature sensors. The first one, installed in the
box, controls the ambient temperature. The second one, installed in the
floor, limits the floor temperature. Electricians or experienced technicians
should install the thermostat.
This thermostat should be connected on a circuit equipped with a fuse or a
circuit breaker. It must be installed on a certified electrical box.
For a new installation, choose a location about 1.5 meters 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 or concealed chimneys or stove
pipes.
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER
PANEL TO AVOID ELECTRICAL SHOCK. Keep air vents of the thermostat
clean and free from obstructions.
PARTS INCLUDED
- One (1) TH132-AF (230 VAC) thermostat
- One (1) temperature sensor with a 3 meter extension
- One (1) wall plate (in certain countries)
1. Installation of thermostat
Turn off power to the heating system at the main power panel to avoid electrical shock.
Unscrew and remove the front part of the thermostat
from the base.
Please take note that the screw cannot be completely
retracted.
If your thermostat is equipped with a wall plate
Before making the connections, make sure that the
base covers the electrical box entirely. If not, insert
the wall plate on rear of the base. (The wall plate can
be used to cover the plate for aesthetics.)
Connect the wires (see section 1.1).
Connect the sensor (see section 1.2).
Secure the base to the electrical box anchorage.
(The head of the screw must be less than 2mm of
thickness.)
0 - 20% 20 - 40% 40 - 60% 60 - 80% 80 - 100%
Set the switches located at the back of the front part
of the thermostat before replacing it in the base.
(see section 1.3)
Affix the front part of the thermostat to the base
using the enclosed screw.
You can now turn the power back on.

3. Connecting temperature sensor wire
Connect the temperature sensor wires to the sensor terminals located at the
back of the thermostat (no polarity needs to be respected).
Note: Do not place the sensor probe directly next to an element but rather,
for maximum performances, the sensor probe should be centered between
the wires in the mat (80 °C max.). The temperature sensor wire cannot lay
across any heater wires.
Adjusting the floor’s maximum temperature
When the floor sensor is installed, the temperature of the floor will automatically be limited the set maximum regardless of the ambient setpoint. To
adjust the floor’s maximum temperature, press on the adjustment button
(see drawing for its position) using a pointed object, and use the and
buttons until the desired setpoint appears.
4. Configuration of switches
a)Early Start function
The thermostat is providing a built-in function enabling it to
calculate the optimum time to start the heating system to
achieve the desired temperature setting at the programmed
time. To enable this function, set the switch E.S. (#1) to “ON”.
b)Temperature in °C or °F
The default configuration of the TH132-AF is in °C. If you wish
to change the temperature to °F, push the switch #2 upward.
Please note that if you change from °C to °F, your Comfort
and Economy settings will need to be reconfigured as well.
POWER-UP
When power is applied for the first time, the
display must show the time 0:00, the floor
ET 32 AF
temperature and the Manual mode icon ( ).
Other information might show up on the display if installation is defective or does not
comply with the instructions.
The message L0 or HI will appear on the display if the temperature sensor is defective or
the temperature is below 0 °C or higher than
60 °C. Also, if the LO message is displayed,
the heating indicator will be present on display and the relay will be closed (current
going in the load).
OPERATING MODES
The TH132-AF has two (2) operating modes.
MANual ( )
This mode allows you to maintain a constant temperature.
1- To activate this mode, press on Mode/Return button to display the

AUTOmatic ( )
This mode executes your own programming.
To activate this mode, press on Mode/Retur n button to display the icon.
k
The or icon indicates which temperature setting is used. Also, the icon

You can switch to the Vacation setting for a prolonged absence by pressing
on the button. The display will show the icon. T he temperature will
remain at this setting until it is returned to the normal operating mode by
selecting the Mode/Return button. The Vacation function is also accessible
through the CT240 telephone controller. If you wish to immediately return to
the programmed settings, press on Mode/Return button.
PROGRAMMING
Programming the time and day
1- Set the time using the Hour and Min buttons.
2- Set the day using the Day button.
Programming the Comfort, Economy and Vacation settings
The Comfort , Economy and Vacation settings respectively repre-
sent the temperatures that you wish to have during the day , at night or
while you are away at work , or while you are away for an extended period
.
To program your settings
a) To p rogram the Comfort temperature, select the desired setpoint using
the buttons and press the button until the icon is displayed
(app. 3 seconds).
b) To program the Economy temperature, select the desired setpoint
using the buttons and press the button until the icon is displayed (app. 3 seconds).
c) To program the Vacation temperature, select the desired setpoint using
the buttons and press on the button until the icon is d isplayed (app. 3 seconds).
d) Press the Mode/Return button to exit this function and return to the nor-
mal operating mode.
Schedule programming
The TH132-AF allows 4 setting changes for each day of the week. There are
no pre-set programs. The programs are tailored to perfectly adapt to your life
style. The principle is very simple. For each day, enter the time at which you
wake up (P1), the time you leave for work (P2), the time you arrive back
home (P3) and the time you go to bed (P4).

For savings to be obtained, you must lower the temperature for a period of at
least 2 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 less than 2 hours.
