Extra controller |
An independent temperature controller for regulating of additional heater or cooler. The controller has an analog input signal for temperature sensors and an analog output signal 0 to 10 V. There is also a digital output signal which is activated when the analog output signal is above 10% (1 V) and deactivated when the analog signal is below 1% (0.1 V).
The controller is configured to be active all the time, follow operation of the unit, run only during defrosting or follow the scheduler.
An alarm will be triggered if Extra controller is in manual override or if a sensor error occurs. The extra controller can also be enhanced with the frost protection if a water based heater is used.
