CAUTION:
• Installation must be carried out by a certified electrician and must comply with national and local
electrical codes.
• Use the CT230 linked unit for resistive load only.
• Do NOT install the CT230 linked unit in an area where it can be exposed to water or rain.
• To prevent severe shock or electrocution, always turn the power OFF at the service panel before
working with wiring.
• Install the CT230 linked unit onto an electrical box.
• Connect the wires using solderless connectors for copper wires. Use special CO/ALR solderless
connectors for connection to aluminum wires.
• Keep the top and bottom air vents (openings) of the CT230 clean and unobstructed at all times.

ENGLISH
The CT230 linked unit is designed to be used in a system for large floor heating applications whose load
is too high for a single conventional thermostat. The system consists of a master thermostat and multiple
CT230 linked units (see diagram on the following page). The heating area is divided into zones of 15 A or
less, each zone connected to a CT230 linked unit. The user sets the temperature and programs the heat-
ing schedule on the master thermostat.
• Each CT230 linked unit is powered by line voltage (120 VAC or 240 VAC) and has its own ground fault
protection mechanism. Up to 10 CT230 linked units can be used in a given setup.
• The master thermostat (non-included) can be a TH113, TH114, TH115 or TH116 thermostat operating
on 12 VDC. The master thermostat is powered by one of the CT230 linked units.
Supplied Parts
• One (1) CT230 linked unit
• Two (2) mounting screws
• Four (4) solderless connectors for copper wires

Install each CT230 linked unit as follows:
nTurn the heating system off at the main electrical panel.
oLoosen the bottom screw and remove the CT230 faceplate from
the wallplate. (The screw cannot be completely removed.)
pConnect the wallplate to the load (heating cables) and to the
power supply (see wiring diagram on page 6).
NOTE: The CT230 linked units can operate on different voltages
in the same setup (e.g., 5 units @ 120 V and 5 @ 240 V).
qInstall the wallplate to the electrical box using the provided
screws.

WARNING: Make sure all CT230 linked units are Off.
nConnect the master thermostat to the nearest CT230 linked unit (see connection diagram on page 7).
WARNING: Only one CT230 linked unit must be used to power the master thermostat.
oConnect the floor sensor (non-included) to the master thermostat (no polarity, see connection diagram on
page 7).
• Position the sensor cable such that it does not come in contact with the floor heating wires. The sensor
must be centered between two floor heating wires for best temperature control.
• Do NOT staple the sensor head (the plastic end) to the floor. Doing so might damage the sensor. Any
damage might not be noticeable during testing but can become apparent several days later.
pLoosen the bottom screw and remove the faceplate from the wallplate. (The screw cannot be completely
removed.)
qInstall the wallplate on the wall using the provided screws and wall anchors.
rReinstall the faceplate on the wallplate.
sApply power to heating system and switch each CT230 linked unit and the master thermostat to On.
tTest the ground fault protection on each CT230 linked unit.

ENGLISH
The CT230 linked unit, with built-in ground fault protection, is different from conventional thermostats. In
the event of a ground fault, the ground fault protection mechanism on the CT230 linked unit will trip and
quickly stop the flow of electricity to prevent serious injury.
Definition of a ground fault
Instead of following its normal safe path, electricity passes through a person’s body to reach the ground.
For example, a defective floor heating mat can cause a ground fault.
Ground fault protection, does not protect against circuit overloads, short circuits, or electrical shocks. For
example, you can still receive an electrical shock if you touch bare wires while standing on a non-
conducting surface such as a wood floor.
Ground fault protection reset
When the ground fault protection mechanism trips, the TEST light is On (red). To reset the ground fault
protection, switch the CT230 linked unit to OFF and back to ON. The TEST light will turn off if the ground
fault protection is functioning properly.
Ground fault protection (GFCI)

ENGLISH
Testing the ground fault protection
To ensure the ground fault protection on each CT230 linked unit is always in working order, test it after
installation and on a monthly basis thereafter.
nIncrease the setpoint temperature on the master thermostat above the mea-
sured temperature in order to activate the heating system.
oPress the TEST button.
• If the TEST light does NOT turn On, the test has failed. Cut power to the
heating system at the main electrical panel, have an electrician verify the
installation and, if necessary, replace the CT230 linked unit.
• If the TEST light turns on, continue the test.
pSwitch the CT230 linked unit to OFF then back to ON.
• If the TEST light turns off, the test has passed. Set the master thermostat back to the desired
temperature. The test is now completed.
• If the TEST light remains on, the test has failed. Continue with the rest of the procedure.
qSwitch the circuit breaker (at the service panel) of the heating system to off then back to on.
rRepeat the test. If the test fails again, cut power to the heating system at the main electrical panel,
have an electrician verify the installation and, if necessary, replace the CT230 linked unit.

L’unité CT230 est conçu pour être utilisé dans un installation pour planchers chauffants de grande surface
ayant une charge trop élevée pour un seul thermostat conventionnel. L’installation comprend un thermos-
tat maître et plusieurs unités CT230 (voir le schéma sur la page suivante). Ce système permet de diviser
la surface à chauffer en zones de 15 A ou moins. Chaque zone est reliée à un unité CT230. L'utilisateur
règle la température et programme l'horaire de chauffage à partir du thermostat maître.
• Chaque unité CT230 est alimenté par la tension secteur (120 V ou 240 V) et est muni de son propre
dispositif de protection de fuite à la terre. Le nombre maximale des unités CT230 dans une installation
est de 10.
• Un thermostat TH113, TH114, TH115 ou TH116 alimenté par du 12 V peut servir comme thermostat
maître (non-inclus). Le thermostat maître reçoit son alimentation d'un des unités CT230.
Pièces fournies
• Un (1) unité CT230
• Deux (2) vis de montage
• Quatre (4) connecteurs sans soudure pour fils de cuivre
