8. Device operation description
Control panel
The controller of universal oil heater type MTM 52 is equipped with an adjusting knob and two
buttons, which enable the user to control the heater operation, and two diodes indicating the operation
phase of the device, connected to a sound signal in the case of a device failure.

The device operates in the following phases:
Stop device ready to operate
Firing up initial phase of device operation
Operation proper phase of device operation
Damping device shutdown process
Overheating emergency shutdown
Overflow emergency shutdown
Heat generation occurs through the combustion of gas produced by the oil heated to high
temperature. At the moment of connecting it to the power network, the device is
in the standby phase (Stop) - no heat is generated, the fan and the pump do not
operate. The diode STANDBY lights on the controller in this time. Pressing the button Start causes the
diode OPERATION to light up and the stove to go into the firing up phase. During this phase, the
diode
OPERATION is blinking. When the furnace has heated up to ca. 40°C, contact shorting of the
control thermostat located next to the combustion chamber occurs and the oil feeding pump and
the downcast ventilator start to operate. On the controller, the diode PUMP lights up, which will blink
for 30 minutes, and the diode OPERATION stops blinking and starts to light
constantly. Due to decreased oil demand by a not heated furnace, after the start-up of the
pump and the fan, the device will operate on minimal power for 30 minutes.
During this time, the pump feeds the furnace with ca. 3 l/h of oil.
After 30 minutes of constant operation, the diode PUMP will stop blinking. The device power may
now be regulated with the knob on the control panel. During maximum power operation,
the furnace is fed with ca. 4.5 l/h of oil.
