Type MTC with air sensor or floor sensor
57915A 11/11 (MBC)
MTC is an electronic heating thermostat
designed to be installed in a standard single
gang electrical box with a minimum width of
2-1⁄4". Once installed, it requires no
maintenance.
An LED illuminates to indicate „call" for heating,
this also aids in system testing. An ON/OFF
selector switch on the front of the cover makes
system operation extremely simple.

FLOOR SENSOR INSTALLATION
(where applicable)
The sensor shall be mounted in a conduit which
should be sealed and placed as high as
possible in the concrete, etc. The sensor is UL
recognised and CSA certified. The sensor wiring
may be extended up to 150' (50 m) using 18
gauge wire and the wiring resistance shall not
with floor sensor
exceed 20 ohms. Sensor wires must be kept in
a separate conduit, away from all other wiring.
The sensor and wires must be protected from
damage during the installation. If shielded wire
with floor sensor
is used, it must not be grounded but connected
to terminal 6 on the thermostat.
with floor sensor
ERROR DETECTION
The MTC has built-in error detection which will
de-energize the heating circuit if the sensor is
damaged or if it detects an open or shorted
sensor circuit.
with floor sensor
CAUTION!
Disconnect all electrical power prior to
installing or servicing this unit.
with floor sensor
THERMOSTAT INSTALLATION (fig. 1-2)
1. Remove thermostat knob, noting the
position (A).
with floor sensor
2. Loosen screw to remove frame and cover
(B).
3. Attach wiring from the rear of the thermostat
according to the wiring diagram.
4. The thermostat is mounted in a standard
single gang electrical box with a minimum
width of 2-1/4". Please ensure that the
adapter plate is properly clipped on the
thermostat.
- re-install frame and cover
- re-install the knob in the proper position
TEMPERATURE SETTING/ADJUSTMENT
Adjust the temperature knob to the desired
room or floor temperature, if after a few days
you find the temperature to be different from the
setting, adjustment can be made as follows:
Measure the room temperature with
thermometer, remove the knob without rotating
it, then reposition the knob according to the
measured temperature on the scale and re-
install it.
MAXIMUM/MINIMUM TEMPERATURE
LIMITATIONS
Behind the knob there are red and blue locking
rings held in position by a screw. To set the
limitations, loosen the screw (C) and adjust the
red limit ring to the desired maximum, set the
blue ring to the desired minimum temperature,
then retighten the screw. The knob must be re-
installed exactly as it was removed.

Type MTC avec capteur thermique ou
capteur de sol.
MTC est un thermostat électronique pour
installation de chauffage dont la conception
permet une installation directe dans un boîtier
électrique encastré standard avec un largeur de
min. 2-1⁄4" et ne demande aucun entretien une
fois installé.
Une diode électroluminescente "LED" s'allume
pour faire "appel" à la source de l'installation de
chauffage, celle-ci sert aussi en cas d'un
contrôle éventuel du système (test). Un
commutateur "Marche/Arrêt" placé sur la partie
frontale du couvercle permet une exploitation
du système d'une extrême simplicité.
