BITERMO-Pt100 controller
BITERMO-Pt100 The mode of operation and other crucial parameters of control are adjusted by means of two micro-switches located inside the controller’s housing.
The controller is suitable for interoperation with two or three terminal Pt100 resistance sensors (connection with a three-wire cable in order to minimize the resistance influence of cables on temperature indications or with a two wire cable). The controller is offered without a Pt100 sensor that must be ordered separately.
Wiring diagram of the BITERMO-Pt100 controller with sensors and modules control:
Characteristics:
- temperature measurement is made by means of the Pt100 resistance sensor,
- a built-in ‘ON/OFF’ section with a relay output, voltage-free (NO and C contacts of a relay, load current up to 3A),
- large, easy to read three-digit LED display.
Functions:
- choice of the mode of operation(ventilation/heating),
- change of the stage of section operation by means of one parameter: preset temperature,
- hysteresis width adjusted by means of settings, independently for positive and negative deviation of temperature,
- periodical ventilation: setting the cycle duration.
