3 Description of Function
3.1 Purpose of the Device
The 979429.02 Temperature Controller is a high-precision tool for either simple ON/OFF two-position
control and three-position control (difference temperature between two temperature values) or
optionally with performance approximation via P.I.D. operating mode.
With freely programmable hysteresis in ON/OFF mode.
The model type 979429.02 was designed for heating and cooling operation in a control range between
-1
99 … 2.300°C. The measuring range is determined by the employed sensor type.
Simple operation and parameterization as well as useful additional functions such as recognition of sensor
damage with automatic power cut-off, alarm output, 3 completely free configurable switching outlets etc. offer
the necessary flexibility for industrial use. Due to the freely programmable hysteresis overlaps with rising or
falling edges, additional possibilities for use as temperature limiter or as unilateral edge-controlled switching
conditions arise for two-position or three-position operation
