1. DESCRIPTION
Temperature controller for cooling or heating applications with two independent thermostats, allowing
operations in two different environments. In addition, the outputs of the thermostats can be configured
as cyclic timers and the alarm output can be linked to any of the thermostats. It also includes an audible
alarm (buzzer), configurable digital filter, and an intelligent function lock system to prevent unauthorized
people from changing the control parameters.
2. SAFETY RECOMMENDATIONS
- Check the controller for correct fastening;
- Make sure that the power supply is off and that it is not turned on during the controller installation;
- Read the present manual before installing and using the controller;
- Use adequate Personal Protective Equipmenet
- For application at sites subject to water spills, such as refrigerated counters, install the protecting vinyl
supplied with the controller;
- For protection under more critical conditions, we recommend the Ecase cover, which we make
available as an optional item (sold separately);
- The installation procedures should be performed by a qualified technician.
3. APPLICATIONS
• Boilers
• Heaters
• Freezers

(*)
This device can measure and control temperatures of up to 200 °C when used in conjunction with a model SB59 silicon
sensor cable (sold separately).
Note: Sensor cable length can be increased to up to 200 meters by using a PP 2 x 24 AWG cable.

6.1. Recommendations of standards NBR5410 and IEC60364
a) Install overload protectors in the controller supply.
b) Install transient suppressors – suppressor filter (RC type) – in the circuit to increase the service life of
the controller relay.
c) The sensor cables may be together, but not in the same conduit where the power supply of the
controller and/or of the loads passes through.
7. FASTENING PROCEDURE
a) Cut out the panel plate (Image V - item 12) where the controller shall be fastened, with sizes X =
71±0.5 mm and Y = 29±0.5 mm;
b) Remove side locks (Image VI - item 12): to do that, compress the central elliptical part (with the Full
Gauge Controls logo) and move the locks backwards;
c) Introduce the controller in the notch made on the panel, inwards;
d) Place the locks again and then displace them until they compress into the panel, fastening the
controller to the housing (see arrow indication in Image VI - item 12);
e) Perform the electric installation as described in item 6;
f) Adjust the parameters as described in item 8.
WARNING: for installations requiring liquid tight sealing, the notch sizes for the controller
installation should be no more than 70.5x29mm. The side locks should be fastened so that they
press the sealing rubber avoiding infiltration between the notch and the controller.
Plus key
Protector vinyl - Image VII (item 12).
This adhesive vinyl is supplied with the instrument in the package
IMPORTANT: Make the application only after completing the electrical connections.
a) Retreat the side locks (Image VI - item 12);
Minus key
b) Remove the protective film from the adhesive vinyl face;
c) Apply the vinyl over the entire upper part, bending the flaps, as indicated by the arrows - Image VII
(item 12);
d) Reinstall the locks.
Note: The vinyl is transparent, allowing you to see the electrical circuitry of the instrument.
