The DC solenoid valve requires that the battery be connected for the system to work properly. If the battery is disconnected or completely discharged the valve operation and the control operation may be affected. In particular, if the control is calling for a fill, the solenoid will be called to open. Opening the solenoid takes a substantial inflow current, which the solenoid may “steal” from the control if it cannot get sufficient power from the battery. This in turn will “fool” the control into believing that a power failure has occurred, which will cause the control to reset and the valve to close. This will occur over and over again. If a
Battery Charging: The Kryos control has a circuit that trickle charges the battery. This provides a fully charged battery for the times when it is needed yet keeps it from being damaged by overcharging. If the battery should become discharged, the following steps should be followed to charge it.
Turn the control off using the Power button on the front panel of the Kryos. Even though the control is turned off, the battery will still be recharged.
Check all connections to the Kryos, especially the harness plug, the wall transformer and the battery extension cable. The wall transformer should be plugged into the wall.

Battery Life
The life of the battery will vary according to many factors including use and storage temperature. The lead- acid batteries have an expected life of 3 to 5 years. For full functionality of your
INTERFACE SOFTWARE
Optional software (CRYOCOM) is available which allows a computer system to communicate with KRYOS through the serial port on the freezer. The software provides the capability to download the logs, review control settings, change control settings and perform system functions such as open/close the solenoid valve, mute the alarm, etc. Contact
The Kryos control is also compatible with the
