| UNITEMP FAMILY CONCEPT: |
UNITEMP is a designation for a series of electronic thermostats for regulation and monitoring of cooling and heating installations as well as industrial plants where accurate regulation is desired.
The UNITEMP units make use of the same types of sensors and accessories. An external control unit ETPP may control 1 or 2 thermostats simultaneously, and regulation by external DC signal is possible, eg from a PLC control. The units are installed on DIN rails. |
| |
| FUNCTION |
The ETP-97 thermostat is useful for heating or cooling function.
3 types cover scale ranges from -30°C to +110°C. Temperature differences may be set by the control knob DIFF.
A light diode lights up, when the relay is energized. |
| |
| Controls |
The SET control serves to set the desired temperature. With a coin inserted into its slot the
scale may be adjusted in accordance with a reference thermometer. Thus, a high accuracy
throughout the entire scale is ensured. The DIFF control enables the temperature differential
to be adjusted from 0,3 to 10% of the scale range.
The SCALE ADJ control allows compensation for sensor tolerances and conductor
resistance. In case of an error in the sensor circuit, the output relay will always fall out. |
| |
| Interconnections: |
An analogue instrument, type ETPD, may be connected to display the sensor temperature.
Voltage outputs 0,5 to 5,5 VDC may be utilized for remote control and data transfer to PLC systems etc.
The setpoint may be controlled externally via External Potentiometer, type ETPP. |
