1. Application
The Revolutions Thermo Regulator is designed to control the power supply of single
phase alternating current units in relation of the temperature of the thermo sensor by means of
a proportional low. The regulation is provided by a phase control of the regulation element
(semistor). The Revolutions Thermo Regulator is optimized to operate with asynchronous and
universal ventilation motors, rotational pumps, etc, but also it can regulate heating elements.
On the other hand, it must be paid attention that it is not suitable for a control of piston
compressors.

J1 Jumper for inversing the slope of the regulation diagram
J2 Jumper for switching off the motor at minimal revolutions level n min
TR2 Element for setting the lower level of the regulation temperature interval T min
TR Element for setting the width of the regulation temperature interval ∆T
TR4 Element for a compensation of the current semistor angle, in order to keep the adjusted
revolutions during the variation of the supply voltage and the loading current.
TR5 Element for setting the minimal revolution level
TR6 Element for adjusting the protection against current overloading

. Operation
The Thermo Regulator changes the motor revolutions depends on the difference
between the assigned temperature level T min and the measured one by the thermo sensor “TS”
in accordance with the chosen regulation diagram.
The possible regulation diagrams are shown on Figure 2 bellow. For each of them it
can be fixed Tmin, ∆T and n min . The motor keeps operating at curves A and B after reaching
the minimal level of the revolutions (n min ) and it stops if the motor reaches the minimal level

of the revolutions (n min ) if curves C and D are selected. The type of the regulation curve can
be chosen and fixed by jumpers J1 and J2, according the table shown at Figure 1b.
Figure 2
The core of the control process is in the provided additional compensation of the
semistor current angle. In fact each voltage increasing will decrease the current angle and on
the other hand, each increasing of the loading current will increase the semistor current angle.
Actually that prevents decreasing of the revolutions during increasing of the shaft mechanical
loading, as well increasing of the revolutions during increasing of the power supply. The
compensation effect is getting bigger during turning TR4 element counterclockwise. Such a
control is very suitable for motors with variable loading, for temperature control pumps in
heating systems with thermo-valves, where it provides permanent pressure level at variable
flow.
The protection against current overloading is provided at two levels In and 1.4In. If
the loading current reaches the level In, the LED1”I>” indication will be activated without
stopping the motor. If the loading current keeps increasing until it reaches the level 1.4In, the
motor will go into minimal revolutions regime fixed by TR5. On the other hand, after
decreasing of the loading current down to 0.5In the LED1”I>” indication stops and the motor
is automatically restarted with a smooth start-up.
The adjusting of the current protection can be done by turning TR6 element clockwise
to the end. The motor is settled by force in maximum revolutions regime (that correspond to
current level In.) by switching off the thermo sensor “TS” of its terminals 11 and 12, and
placing the jumper J1 at a position related to curve A (Figure 1b). After that TR6 element
must be turned smoothly counterclockwise, until LED1 “I>” light indication appears,
afterwards TR6 must be turned back slowly until the light indication stops remaining it in that
position.
Adjusting of the minimal revolutions level is provided by switching off the sensor
“TS” from terminals 11 and 12, and placing the jumpers J1 and J2 according curve B (Figure
1b). The minima level of the revolutions can be adjusted by means of TR5 element.
The motor can be stopped or started by remote circuit closer placed outside the
Regulator body. The motor operates if the circuit closer is closed and it stops if the circuit
closer remains open.

·Terminals 1 and 2 are designed for a remote circuit closer for a start/stop.
·Terminals 3 and 4 outputs a for motor control
·Terminals 11 and 12 input for a connection of the temperature sensor type
LM335, provided by INTIEL. Take into account the sensor correct polarity
during its connection.
9. Warranty period
The warranty period is 24 months following the purchase date of the unit or its
installation by an authorized Engineering Company, but not exceeding 28 months after the
production date. The warranty is extended to the malfunctions that occur during the warranty
period and are result of the production reasons or defective used parts.
The warranty does not relate to malfunctions corresponding to not-qualified
installation, activities directed to the product body interference, not regular storage or
transport.
The repairs during the warranty period can be done after correct filling of the
manufacturer warranty card
