Control Components

Interface Panel

The KRYOS Interface panel, which the user will interact with, contains the vacuum fluorescent display as well as the number keypad, power button, help button and the soft-key control buttons. (See figure 1.0 below.)

Main Control

The “brain” for the control system “talks” to the interface unit and makes all decisions regarding liquid levels, temperatures, valve opening/closing, etc. It is located away from the Interface Panel on the upper outer head. (See figure 2.0 below.)

Sensor Assembly

A standard 7+1 thermistor assembly, includes the Freeze-Guard over-fill sensor. Optional 4-thermistor, or 8- thermistor sensor assemblies can be ordered. The 4-thermistor assembly maintains the liquid level between 2 middle sensors. The 8-thermistor assembly maintains the liquid level between the high sensor and the low sensor assigned by the user. The standard 7-thermistor assembly is similar to an 8 sensor assembly in that the user can select the START FILL and STOP FILL positions. The eighth position on this assembly is tied into an inline plumbing thermistor, which detects if the solenoid valve fails to close.
