1. Description
The TSSHC-3NPSBFS-16A non programmable electronic thermostat can be used to control ENERJOY radiant ceiling panels or heating oors with electrical current − with a resistive load
− ranging from 0 A to 16 A at 120/208/240 VAC. It has an easy
user interface. It keeps the temperature of a room (Ambient
mode) and a oor (Floor mode) at a requested set point with a
high degree of accuracy.
Floor Mode (factory setting)
This control method is ideal in areas where you want a hot oor
at any time and when the temperature of the ambient air can be
high without causing discomfort. For example, in a bathroom.
Ambient Mode (you only have to press down the A/F button to
switch from one mode to the other)
This control method is ideal when you want a stable ambi ent air
temperature (without uctuation). Usually, this mode is used in
large and often occupied rooms where temperature variations
can be uncomfortable. For example, in a kitchen, a living room
or a bedroom.
Some factors cause variations in ambient air temperature. They
include large windows (heat losses or gains due to out side temperature) and other heat sources such as a central heating system, a replace, etc. In all these cases, the Ambi ent mode will
ensure a uniform temperature.
This Thermostat is not compatible with the following
installations:
• electrical current higher than 16 A with a resistive load
(3840 W @ 240 VAC, 3475 W @ 208 VAC and 1920 W @
120 VAC);
• inductive load (presence of a contactor or relay); and
• central heating system.
INS-TSSHC-3NPSBFS-16A-12094
Installation work and electrical wiring must be done
by qualied person(s) in accordance with all applicable State/Country codes and standards.
• Parts supplied:
• one (1) thermostat;
• two (2) mounting screws;
• four (4) solderless connectors suitable for copper wires; and
• one (1) oor sensor.
2. Installation
Thermostat selection and sensor location
The preferred thermostat location is on an inside wall four feet
(1.2m) above the oor, in a conveniently accessed locations
such as next to the light switch, and away from random temperature impacts detailed in the examples that follow.
Do not install the thermostat in a location where temperature
measurements could be altered. For example:
• close to a window, on an external wall, or close to a door
leading outside;
• exposed directly to the light or heat of the Sun, a lamp, a
replace or any other heat source;
• close or in front of an air outlet;
• close to concealed ducts or a chimney; and
• in a location with poor air ow (e.g. behind a door), or with
frequent air drafts (e.g. head of stairs).
To install the sensor, refer to the installation guide of your heating oor.
Thermostat mounting and connection
1.
Cut off power supply on lead wires at the electrical
panel in order to avoid any risk of electric shock.
2. Ensure that the air vents of the thermostat are clean and clear
of any obstruction.

3. Using a screwdriver, loosen the screw retaining the mount ing
base and front part of the thermostat. Remove the front part
of the thermostat from the mounting base by tilting it upward.
4. Align and secure the mounting base to the connection box
using the two screws supplied.
5. Route wires coming from the wall through the hole of the
mounting base and make the required connections using
the “Four-wire installation” gure, and using the supplied
solderless connectors. A pair of wires (black) must be connected to the power source (120-208-240 VAC) and an other
pair (yellow) must be connected to the heating cable (refer to
the drawings displayed on the back of the thermo stat). For
connections with aluminum wires, you must use CO/ALR
INS-TSSHC-3NPSBFS-16A-12096
connectors. Please note that thermostat wires do not have
polarity, meaning that any wire can be connected to the other.
Then, install the oor temperature sensor.

3. Operation
First Start-up
At the rst start-up, the thermostat is initially in the Day and
Floor modes. The temperature is displayed in degrees Cel sius
and the standard factory set point adjustment is 77ºF (25ºC).
The maximum oor temperature is limited to 82°F (28°C).
Maximum oor temperature limitation
At any time, the oor temperature (both in Floor and Ambi ent
modes) is maintained at less than 82°F (28°C) in order to avoid
overheating caused by an excessive heating request, which
could damage some materials or be detrimental for health.
INS-TSSHC-3NPSBFS-16A-12098
Temperature set points
The gures beside the word SET indicate the temperature set
points (both in Floor and Ambient modes). They can be displayed in degrees Celsius or Fahrenheit (see “Display in degrees
Celsius/Fahrenheit”).
Out of any adjustment mode, press down the + button to increase the set point, or the – button to decrease it. Set points
can only be adjusted by increments of 1 degree. To quickly
scroll through the set point values, press and hold down the button. Both in manual and automatic modes, the (Ambient) mode
set points can range between 37 to 95°F and can only be adjusted by increments of 1°F (from 3 and 35°C; by increments of
1°C from the Celsius mode). From (Floor) mode, the set points
can range between 37 and 82°F (from 3 to 28°C) (if the maximum oor temperature set is 82°F (28°C)).
In Day mode, you can turn off the thermostat by lowering the
set point below 37°F (3°C). The set point value displayed will be
OFF, and heating system start up will be impossible.
Maximum Floor Temperature Limitation
At any time, the oor temperature (in Floor mode) is maintained
at less than 82°F (28°C) in order to avoid overheating caused by
an excessive heating request, which could damage some materials or be detrimental for health. It is however possible to increase this limit to 37°C (99°F) by increment of 1°C. To do so,
you must:
1. Press down the A/F button for at least 20 seconds. After 20
seconds, the actual maximum temperature will be displayed
in replacement of the Floor mode set point and will blink
during 5 seconds. Then, you can release the A/F button.
2. Press down the + button to increase this limit or – button to
decrease it.
Regardless of the maximum oor set point (Floor mode), the
maximum Ambient mode set point will always be 35°C (95°F).
INS-TSSHC-3NPSBFS-16A-1209 9
Day mode and Night mode
The thermostat includes a Day mode (Sun) and a Night mode
(Moon), both of them having their own independently adjustable and recorded set point. When switching from one mode
to the other, the system will automatically use the temperature set point corresponding to the Day/Night mode selected.
The Floor and Ambient temperature are displayed by the gures under the words Ambient and Floor, and the temperature
set points are displayed by the gures beside the word SET,
both in degrees Celsius or Farenheit. The standard factory set
point adjustment is 77°F for the Day/Floor mode (68°F from the
Ambient mode), and 72°F for the Night/Floor mode (60°F from
the Ambient mode).
In order to manually switch from one mode to the other, simultaneously press down the + and – buttons and release them
immediately.
Night mode timer
The Night mode features a timer that automatically returns to
the Day mode after a selectable time period. This timer allows
the temporary use of a temperature set point. The standard factory adjustment of the timer is 8 hours. With this adjust ment,
the thermostat automatically returns to Day mode 8 hours after being switched to the Night mode. You can switch from the
Floor mode to the Ambient mode without affecting the timer
adjustment.
For example, if you want a night temperature lower than the day
temperature, both Day/Night modes set points will rst have to
be set at the desired temperatures. Before bedtime, the Night
mode temperature set point will be activated by switching manually to the Night mode. The timer is set for the duration of the
night. The thermostat will automatically return to the Day mode
at the end of the night, and the Day mode temperature set point,
which is higher, will become effective at this time.
INS-TSSHC-3NPSBFS-16A-120910
Night mode timer adjustment procedure
1. First, switch to the Night mode by simultaneously press ing
down the + and - buttons and releasing them imme diately.
2. From the Night mode, simultaneously press down the + and -
buttons for more than 3 seconds until the icon SET starts
to blink, indicating that the adjustment of the Night mode
timer is effective. The gures that replace the Ambi ent mode
temperature indicate the current adjustment of the timer and
‘‘hrs’’ replaces the Floor mode temperature.
3. If needed, adjust the timer by pressing down the + button
to increase the value, or the – button to decrease it. The
adjustment range is from 1 hour to 999 hours. To quickly
scroll through timer values, press and hold down the but ton.
4. When the adjustment is completed, release the buttons
and wait for 5 seconds to exit the adjustment function. The
thermostat will then return to the Night mode.
N.B.
The Night mode timer will be automatically reinitialized to the
latest recorded value when switching from the Day mode
to the Night mode. It is not necessary to read just the timer
every time you switch to the Night mode. The timer is also
reinitialized when this value is adjusted. Once the timer has
completed its cycle and when the thermostat is in the Day
mode, you must manually return to the Night mode. If you
want to automatically return to the Night mode, the Automatic
mode must be selected.
INS-TSSHC-3NPSBFS-16A-1209 11
Automatic mode
The Automatic mode, which is associated to the Night mode
timer, allows alternating between the Day/Night modes and the
two corresponding set points over a 24-hour period. Once activated, this mode allows an automatic return to the Night mode
after 24 hours. The Automatic mode allows you to de ne two
periods in a single day with different set points.
For example, if the Automatic mode is activated and the Night
mode timer is set at 8 hours, the thermostat will be op erating in
the Night mode for 8 hours at the night temperature set point.
Then, it will return to the Day mode for 16 hours operating at the
day temperature set point. At the end of the 24-hour cycle, the
thermostat will return to the Night mode, and the cycle will start
again. The 24-hour cycle starts with the Night mode as soon
as the Automatic mode is activated. The Automatic mode activation should be made when you want to return to the Night
mode. The normal course of a cycle in the Automatic mode is
as follows:
1- Night mode: activated for the duration of the Night mode
timer cycle. It returns to the Day mode when the timer cycle
is completed.
2- Day mode: activated for the remaining time of the 24-hour
cycle. It returns to the Night mode at the end of the 24-hour
cycle.
INS-TSSHC-3NPSBFS-16A-120912
Adjustment procedure of the Automatic mode:
1. First, switch to the Night mode by simultaneously press ing
down the + and – buttons and releasing them imme diately.
2. From the Night mode, simultaneously press down the + and –
buttons for more than 3 seconds, until the icon SET starts to
blink, indicating that the adjustment of the Night mode timer
is effective. The gures that replace the ambi ent temperature
indicate the current timer adjustment. If needed, adjust the
timer by pressing down the + button to increase the value, or
the – button to decrease it. The Night mode timer adjustment
range is from 1 hour to 23 hours in the Automatic mode. To
quickly scroll through the timer values, press and hold down
the button.
N.B. If you set the timer to any value exceeding 23 hours, it will
be impossible to activate the Automatic mode and if it was
activated, the Automatic mode will be deacti vated.
3. Activate the Automatic mode by simultaneously pressing
down the + and – buttons for at least 3 seconds. The Automatic mode icon will appear. If the Automatic mode was
already activated, the same procedure should be used to
deactivate it.
4. When the adjustment is completed, release the buttons and
wait for 5 seconds to exit the adjustment function.
N.B.
It is always possible to manually change the Day/Night mode
during a 24-hour cycle. In all cases, at the end of the 24-hour
cycle, the thermostat will return to the Night mode and start a
new cycle. It is thus not necessary to readjust the Automatic
mode when a manual change is made to the Day/Night
mode. If the thermostat is set OFF, the Automatic mode will
be deactivated.
When the power is restored after a power failure for example,
the Automatic mode is deactivated and its corresponding icon
is blinking. The icon will stop to blink as soon as you will press
down a button.
INS-TSSHC-3NPSBFS-16A-1209 13
Display in Degrees Fahrenheit/Celsius
The thermostat can display the ambient temperature and the set
point in degrees Fahrenheit (standard factory setting) or Celsius.
Adjustment procedure for degrees Fahrenheit/Celsius dis play.
1.
To switch from the degrees Fahrenheit to the degrees Celsius,
and conversely, the thermostat must be from the Day mode. If
so, simultaneously press down the + and – buttons for more
than 3 seconds until the SET icon blinks.
2. Press down the + button to switch from the degrees
Fahrenheit to the degrees Celsius, and conversely. The
degree Fahrenheit or Celsius symbol is displayed.
3. When the adjustment is completed, do not press down any
button during 5 seconds to exit the adjustment function.
Ambient/Floor Mode
To switch from the Ambient mode to the Floor mode, or conversely, press down the A/F button (when you are not in any
adjustment mode). Then, the temperature set point will become the same as the Floor or Ambient mode temperature, as
applicable.
Safe mode
If the thermostat fails to detect the presence of a oor sensor, it
will automatically revert to ambient mode at a setpoint of 70°F.
(with a maximum set point temperature of 75°F)
INS-TSSHC-3NPSBFS-16A-120914
Sensor Selection
If you want to use the TSSHC-3NPSBFS-16A thermostat of
SSHC, inc. with a temperature sensor already installed in the
oor (other than the sensor supplied with this thermostat), you
must con tact the SSHC, inc. customer service to validate the
com patibility between the sensor and the thermostat. You must
know the serial number and name of the installed sensor.
Floor temperature offset
If the oor sensor is not correctly installed, the thermostat will
not indicate the right oor temperature (the indicated temperature will be higher than the reality because the sensor is too
close to the heating cable). This feature allow to decrease the
measured temperature by 0°F to 18°F (0°C to 10°C) by increment of 1°C. To do so, you must:
1. Press down the A/F button for at least 30 seconds, the actual
value of this offset will be displayed in replacement of the
Floor mode set point and will blink. Then, you can release
the A/F button.
2. Press down the + button to increase this offset or – button to
decrease it. This offset will be displayed for 5 seconds.
N.B.
This offset allow only to decrease the measured temperature
and not to increase it. The default value is 0°F (0°C).
Temperature Control
The thermostat controls the oor/ambient temperature (according to the Ambient/Floor mode) with a high degree of accuracy. When the heating starts or stops, it is normal to hear
a “clic” sound. It is the noise of the relay which opens or closes, as applicable.
INS-TSSHC-3NPSBFS-16A-1209 15
Backlighting
The screen lights up when you press down a button. If you
do not press down any button for more than 15 seconds, the
screen turns off.
N.B. If you press down the + or – button once when the back light
is off, it will light up without changing the set point value. The
set point value will change only if you press down one of these
buttons again.
Ground-fault Circuit Interrupter (GFCI)
The GFCI is designed to reduce the risk of electric shock. It
can detect a leakage current of 5 mA. If a defect is detect ed,
the GFCI device lights up, and both screen and heating system
circuit are deactivated. The GFCI can be reinitialized either by
pressing down the Test button or by disconnecting the thermostat at the electrical panel.
Ground-fault circuit interrupter (GFCI) verication
It is important to verify the ground-fault circuit interrupter installation and operation on a monthly basis.
GFCI verication procedure
1- Increase the temperature set point until the heating power
bars are displayed (displayed beside the oor tempera ture).
2- Press down the Test button.
3- The following two cases can occur:
a) Successful test: The red indicator of the thermostat lights
up. In this case, press down once again the Test button
to reinitialize the ground-fault circuit interrupter, the red
indicator turns off.
b) Failed test: The red indicator does not light up and the
entire display blinks during 5 seconds. In this case, disconnect the heating system at the electrical panel.
INS-TSSHC-3NPSBFS-16A-120916
Lock option
It is possible to impose a maximum temperature set point by activating this mode. Then, it becomes impossible to exceed this
set point, regardless of the mode. However, it is still possible
to lower the set point at your discretion. Please note that when
the Lock option is activated, it is impossible to switch from the
Ambient mode to the Floor mode, and conversely.
Lock activation
1. From the Day mode, adjust the set point at the maximum
desired value.
2. From the Day mode, simultaneously press down the + and -
buttons for more than 10 seconds, until the Lock icon displays
(note that the SET icon will also blink after 3 seconds).
3. Release the buttons. The thermostat is now locked.
Lock deactivation
1. Cut off the power supply of the thermostat at the electrical
panel.
2. Wait at least 20 seconds.
3. Restore the power supply of the thermostat at the electrical
panel.
4. The Lock icon is blinking on the thermostat display, meaning
that it is possible to unlock the thermostat.
5. While the Lock icon is blinking, simultaneously press down
the + and - buttons for more than 10 seconds, until the Lock
icon disappears.
6. Release the buttons. The thermostat is now unlocked.
N.B. If the thermostat isn’t unlocked within 5 minutes after the
restoration of the power supply, the Lock icon will stop to
blink and it will be impossible to unlock the thermostat unless
cutting off the power supply again.
INS-TSSHC-3NPSBFS-16A-1209 17
Parameter backup and power failures
The thermostat saves some parameters in its nonvolatile memory in order to recovered them when power is restored (e.g. after a power failure). These are the four set points (Day/ Night/
Ambient/Floor), the Automatic mode, the Lock option, the maximum set point of the Lock option, the Celsius/Fahr enheit mode,
the remaining time of the timer and the maxi mum oor temperature. These parameters are saved every minutes when a change
occur, except for the Day/Night mode and the remaining time
of the timer, which are saved only if the Automatic mode was
not activated.
Please note that the Automatic mode is not automatically reactivated when the power is restored, the Automatic icon blinks
to indicate that this mode was activated before the power failure and that is now deactivated. Moreover, when the power is
restored, the Day/Night mode is recovered only if the Automatic
mode was deactivated before. If not, the Day mode is automatically reactivated. The Lock option is also reactivated if it
was activated before the failure. However, its icon blinks for 5
minutes and you can deactivate this mode by simultaneously
pressing down the + and – buttons for 10 seconds. The Lock
option stays activated if you don’t follow this process and the
icon stops blinking.
