The electronic thermostat is used as a heating or cooling thermostat, but can be optionally extended with a PID two-point controller option.
The device offers user-friendly operation, characterised by a clear structure and supporting texts in German, English, French and Spanish. Process values, texts and parameters are displayed on two 18-segment LCD displays. Additional display elements provide information on the switching positions of the outputs, the status of the timer and the temperature unit used. PCB terminals with push-in technology enable quick electrical installation. Operation, parameterisation and configuration are carried out via a membrane keypad with four buttons.

PID two-point controller (optional)
If the PID two-point controller option is selected, various controller structures are available, including P, I, PH, PI and PID, which also enable self-optimisation. In addition, the setup programme offers a start-up function and a display of the online parameters.

Inputs and outputs
The required analogue input can be selected when ordering:

  •  Resistance thermometer
  •  Thermocouple
  •  Current (4 to 20 mA)
  •  Voltage (0 to 10 V)

There is also a digital input for connecting a potential-free contact (not for resistance thermometers in three-wire circuit).

Depending on the device type, the following combinations are available as outputs: 2 relays (1 changeover contact, 1 NO contact), or 1 relay (NO contact) and 1 digital output DC 0/14 V, or 4 relays (NO contact).

USB device interface
The device has a Micro-B socket, which is intended for connection to a PC for configuration with the setup programme. No separate power supply is required during configuration via the USB interface (USB-powered).

Electrical connection
The electrical connection is made in a time-saving manner using spring-loaded terminals (push-in technology)

Self-optimisation 

Self-optimisation (oscillation method) makes it possible even for users with no knowledge of control technology to adapt the controller to the controlled system. The reactions of the controlled system to changes in the manipulated variable are analysed and certain controller parameters are calculated. 

Limit value monitoring 

The device has three limit value monitors, each of which offers eight configurable alarm functions. Any analogue signal is selected from a selector as the value to be monitored. The limit values can be defined either as an absolute value or as a different analogue signal. Additional functions: 

  •  On/off delay - Wiper function 
  •  Alarm suppression during the switch-on phase or when parameters are changed 
  •  Alarm latching 
  •  Latching with acknowledgement are available. 

Comprehensive alarm and limit value functions can be realised with limit value monitoring.

Timer
After the timer is activated, a signal is output for the preset runtime, which can be inverted. The timer can also be started after a lead time has elapsed or a tolerance limit has been reached. After the timer has elapsed, an end signal can be generated that is either limited in time or can be deactivated by acknowledgement. The timer makes it possible, for example, to realise a time-controlled setpoint changeover.

Service counter
The service counter can either count the number of switching operations of a binary signal or measure its switch-on duration. As soon as the adjustable limit value is reached, a binary signal is activated that must be acknowledged. An operating hours counter is also available, which records the operating time of the device.

Setup programme
The optional setup programme allows the user to configure the device easily and conveniently via a PC. With this programme, data can be created, edited, transferred to the device and read out from there. It also offers a recording function for commissioning (start-up).

Customer-specific linearisation
Individual linearisation according to customer requirements makes it possible to use sensor signals with special characteristics. Programming is carried out in the setup programme either using your value table with up to 40 value pairs or using a formula (4th order polynomial)
