The thermostat control is located in the chiller enclosure. The control has three control keys
and a one-line, four-character LCD display.
The thermostat control has a lockout slide switch to prevent tampering by unauthorized
personnel. The switch is located on the inside cover of the thermostat. The keypad is disabled
when the switch is moved to the left in the "Lock" position. The keypad functions normally
when the switch is moved to the right in the "Unlock" position. All chillers are shipped with
the switch in the "Lock" position.
