Temperature Controller
GENERAL DATA
The microprocessor-based regulator is a versatile
temperature controller for cooling applications with high
measuring accuracy. The equipment is available for
resistance sensor PTC. The switching contact K1 can be
parameterized as norm contact or as limit value min. - max.
The control setpoint and the following parameters are
adjusted by a membrane keypad on the front of the
instrument.
* Setpoint 1
* Switch difference
* Hysteresis at the switch points
* Control range limitation - minimum and maximum value
for the setpoint
* Actual value correction
* Keypad lock
* Limit values
Other device characteristics such as the function of the
output relay and the monitoring and control characteristics
are factory pre-set but can be varied.
