Device connection and commissioning can only be carried out by qualified professionals.
Always make the connections while the power is switched off.
NOTE: The supply voltage potential must be the same in the controller and in the connected 24 Vac
actuators.
The maximum triac output current is 1 A. It is recommended to connect maximum of 4 thermal actuators
to the same controller output. The total current consumption must not exceed 1 A.
The triac outputs are protected with fuses that can only be changed by the manufacturer.
NOTE: Unused inputs and outputs can also be used for transferring other measuring and control
information over the Modbus.
•
The controller settings remain over the power failure.
•
Overdrives made over the Modbus are cleared during the power failure.
