IG – Main switch
The chiller carries no current after it has been turned off with the main switch. The switch is located on
the door of the switch cabinet.
MTC – Motor protection switch for compressor
If the motor current increases beyond the set value or if there is a short circuit, the motor protection
switch turns off and interrupts the current supply. The motor protection switch has to be turned on man-
ually after the cause of the malfunction has been eliminated. The motor protection switch is located in the
switch cabinet.
MTP – Motor protection switch for pump
If the motor current increases beyond the set value or if there is a short circuit, the motor protection
switch turns off and interrupts the current supply. The motor protection switch has to be turned on man-
ually after the cause of the malfunction has been eliminated.
The motor protection switch is located in the switch cabinet.
ROO – Remote control
The chiller can be switched off by the consumer or from a control room with the aid of an external con-
tact. When this occurs, the main switch remains permanently switched on.
QE – Switch cabinet
The switch cabinet contains all the electrical components and safety devices.
TLT – Temperature controller
Temperature control and regulation is carried out by the temperature controller of the chiller in accord-
ance with the preset value.
The temperature controller with digital display is integrated in the door of the switch cabinet. Fault mes-
sages are displayed on the temperature controller by means of codes.
OPTIONS – ELECTRIC CIRCUIT
Connecting cable with CEE plug
A ready-to-use mains cable is supplied with 6m oilflex cable and CEE plug 4-pole (3P+PEN) or 5-pole
(3P+N+PE).
Compressor winding protection
Depending on the compressor type, the protection is provided either by Klixon (bimetal strip) or by a
temperature probe. If the maximum permissible winding temperature is attained, the motor protection
switch turns off the compressor.
