The STCP electronic thermostat can be used to control 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 and can manage up to four programming periods
a day. It keeps the temperature of a room ( mode) and a
oor ( 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 ambient 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 outside
temperature) and other heat sources such as a central heating
system, a replace, etc. In all these cases, the mode will
ensure a uniform temperature.
This thermostat is not compatible with the follow-
ing installations:
• electrical current higher than 16 A with a resistive
load (3840 W @ 240 VAC, 3330 W @ 208 VAC and
1920 W @ 120 VAC);
• inductive load (presence of a contactor or relay); and
• central heating system.

Parts Supplied:
• one (1) thermostat;
• two (2) mounting screws;
• four (4) solderless connectors suitable for copper wires;
• one (1) oor sensor.
Selection of thermostat and sensor location
The thermostat must be mounted on a connection box, at
around 1.5 m (5 feet) above the oor level, on a section of the
wall exempt from pipes or air ducts.
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;
Ensure that the thermostat will be installed on a

base and front part of the thermostat. Remove the front part
of the thermostat from the mounting base by tilting it upard;
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
another pair (yellow) must be connected to the heating
cable (refer to the drawings displayed on the back of the
thermostat). For connections with aluminum wires, you must
use CO/ALR connectors. Please note that thermostat wires
do not have polarity, meaning that any wire can be connected

for the rst time instead, the backlight will be activated. To
quickly scroll through the set point values, press and hold down
the button. From mode, the set points can range between 3
and 35°C and can only be adjusted by increments of 1°C (from
37 to 95°F; by increments of 1°F from the Fahrenheit mode).
From mode, the set points can range between 3 and 28°C
(from 37 to 82°F). The thermostat will turn off if the set point is
lowered below 3°C (37°F), and the set point value displayed
will be --. The standard factory set point adjustment is 21°C
(mode). From this mode, the screen displays the /
mode temperature, the /mode set point, the hour and
the day of the week.
This mode is initially activated when the power is turned on for
the rst time. You must adjust the hour (as described in the
section “Adjustment of the hour and the day of the week”)
before switching to other modes by pressing down the Mode
or Pre Prog button.
Automatic Mode (Auto)
To switch from the Manual mode to the Automatic mode, and
conversely, press down the Mode button. The Man or Auto icon
is displayed at the bottom of the screen as applicable.
From the Automatic mode, the thermostat adjusts the set points
according to the programmed periods. If no data is entered,
the thermostat acts as in Manual mode and the standard
factory set point adjustment is 21°C ( mode). It is always
possible to manually adjust the set point using the + or - button.
The selected set point will be effective until one period is
programmed, which represents an hour and a day of the week.
Note that, if the set point is lowered to off (--), the programming
will not be effective. It is possible to program 4 periods a day,
meaning that the set point can change automatically up to 4
times a day. The period order is not important.
From this mode, the screen displays the temperature, the set
point, the hour, the day of the week and the current programmed
period number (1 to 4; as applicable).
