While cleaning the device or performing other maintenance activity, the device must be
disconnected from the power network by removing the electrical plug from the power socket.
•
While connecting the device to a power network, it must be made sure that the wiring is
operational and that it has differential current protection and earthing.
The MTM 52 universal oil heater is powered by the alternating current network of 230V, 50Hz.
It is equipped with two bimetallic sensors, ensuring safe and economic operation
of the device. The bimetallic sensor located on the heat exchanger reacts with contact shorting when
the temperature exceeds 40°C and with contact opening when the temperature drops below 35°C.
In emergency situations (overheating, oil overflow) the processor checks the bimetallic sensor signal
and maintains the fan operation until the furnace has cooled down to the temperature
below 35°C.
The other bimetallic sensor is located on the heat exchanger as well and its threshold temperature
equals 90°C. Its contact opening resulting from exceeding the threshold temperature causes the stove
to immediately enter the
Overheating
phase (see point 8. in this Manual). The heater is also equipped
with a weight sensor located under the combustion chamber (i.e. the so-called overflow cut-out).
When the tank of the above cut-out has filled up, the stove automatically switches to the phase
Overflow
(see point 8. in this Manual).

Controller structure
The connection of the stove controlling panel to other system components (sensors, pump, fan)
is factory-made. During normal use, due to safety, under no circumstances should there be any
interference in the covered part of the stove controller or duct integrity. Any action by an unauthorised
person may result in electrocution (230V AC, 50Hz) and burning.
