Unit Mode
The overall operating mode of the chiller is set by the Unit Mode Set Point with options of COOL, COOL
w/Glycol, ICE w/Glycol, and TEST. This set point can be altered by the keypad, BAS, and Mode input.
Changes to the Unit Mode Set Point are controlled by two additional set points.
• Available Modes Set Point: Determines the operational modes available at any time with options of
COOL, COOL w/Glycol, COOL/ICE w/Glycol, ICE w/Glycol and TEST
• Control Source Set Point: Determines the source that can change the Unit Mode Set Point with
options of KEYPAD, NETWORK, or SWITCHES.
Whe
n the Control source is set to KEYPAD, the Unit Mode shall stay at its previous setting until changed
by the operator. When the Control source is set to BAS, the most recent BAS mode request shall go into
effect even if it changed while the Control source was set to KEYPAD or DIGITAL INPUTS.
Changing the Unit Mode Set Point can be accomplished according to the following table.

Unit Test Mode
The unit test mode allows manual testing of controller outputs. Entering this mode requires the following
conditions:
• Unit Switch = OFF
• Manager password active.
• Available Unit Mode set point = TEST
A test menu can then be selected to allow activation of the outputs. It shall be possible to switch each
digital output ON or OFF and set the analog outputs to any value.
Circuit Available
A circuit is available if the circuit switch is in the on position and no circuit alarms are active. Timers that
delay startup or staging of a circuit do not render it unavailable.
