When System Control is in  Remote mode, see  Figure 1-9, the transmitter is 
responsible for control of the cooling system, including ON/OFF, manual pump 
selection and automatic pump switching in the case of a failure. Placing the control 
panel in Local mode allows manual switching of the pumps.
The red selector at the top of the control panel (labeled ON/OFF) is the AC isolation 
switch which disconnects AC power from the pump module as well as the control 
circuitry in the control panel itself. 
In the local mode, with the AC isolation switch set to ON, one of the two pumps will be 
energized unless the Pump Interlock is active. To deenergize the pumps, when in the 
local mode, set the AC isolation switch to OFF.
