The device PROCTO gives the possibility to perform the block command and to grasp
diagnostic information only in conjunction with an electronic thermostat.
The current version of the PROCTO includes the compatibility with the
Danfoss ERC 111 and 112 thermostats.
For other models and brands please contact your commercial contact.
3. Compatibility
The PROCTO requires two connections, one for the power supply, the other with the electro
nic thermostat.
4. Connections and wires
The power supply can be shared with the electronic thermostat: the PROCTO device does not require
additional power adapter.
Note: All the cables have to be assembled by the Cooler Manufacturer following the instructions here below.
For the POWER SUPPLY connector of the OCTO, either two standard fast-on connectors or one
connector with screw terminal can be used. Fig. 5 on the right, illustrates the Lumberg 3611 02 K1, an
easy plug connector with lift clamp and protection against misplacing and fast assembling. Neither
the standard fast-on connectors nor the easy plug connector are included in the OCTO package.
Note: If the power supply cable is not double insulated, it has to be physically separated from the
COMM cable.
