Brief description
The electronic thermostat can be used as a heating or cooling thermostat or optionally as a PID two-state
controller. It acquires the process variables via RTD temperature probe, thermocouple, current 0(4) to
20 mA, or voltage 0 to 10 V. When used as a PID two-state controller, the controller structures P, I, PD,
PI, and PID are possible.
The device type 701080 is available with 2 relays or with 1 relay and 1 digital output (DC 0/14 V); the
device type 701081 is equipped with 4 relays (common pole).
The device is characterized by simple, clearly structured operation supported by texts in English, Ger-
man, French, and Spanish. Process values, texts, and parameters are shown in two 18-segment LCD
displays. Additional display elements inform about the switch positions of the outputs, the timer status,
and temperature unit.
Terminal blocks with PUSH IN technology enable fast electrical installation.
Operation, parameterization, and configuration are carried out via a membrane keyboard with four keys.
The setup program on a PC allows the devices to be configured without any problems. No separate volt-
age supply is required when configuring via the USB interface (USB-powered).
