TEMPERATURE CONTROLLER – OPERATION MANUAL – V2.6x
The controller should be installed in a panel cut out as specified in
item 2.1. First remove the mounting clamp and insert the controller
into the panel cut out. Place the unit into the panel cut-out and slide
the mounting clamp from the rear to a firm grip at the panel.
The internal circuitry can be fully removed from the housing without
disconnecting any wiring. By using the thumb just press the tab in
the lower part of the front panel, grab firmly the front panel and pull
out the circuitry from the housing.
Figure 1 shows the electrical terminals of the controller.

displayed and the control output is turned off.
Alarm Output 1: SPST relay 3A/250Vac or 5Vdc/20mA
Alarm Output 2: SPST relay 3A/250Vca (optional)
Mains power is connected to terminals 5 and 6. Check the upper
side of the housing for proper power indication.

3. CONFIGURATION AND OPERATION
Prior to first operation the controller should be fully configured. The
user must set basic parameters as temperature type (“TYPE

Alarms and tuning level
At power up the controller displays a prompt at the Operation Level
and remains in this level while under normal operation.
The other levels are only accessed when a change of parameters is
necessary (except for Set Point change). To reach these other
parameters the user must keep the INDEX Key ( ) pressed for
about three seconds. After this time the controller will show the first
parameter of the next level. By keeping the INDEX key pressed for
another 3 seconds the next level will be accessed.
key when the desired level is reached. Press once
to go to the next prompt in the same level.
When a parameter is shown the display will alternate its name and
value. The value can then be changed by pressing the
