11.2.1 Compressor Start Delay (5-135sec;
15sec
)
The compressor start delay is used for installations where more than one system operates
from the same power source. Setting different start delays allows compressors to start at
different times when AC power is interrupted. Stage the units at least 5 seconds apart. Note
that this delay is only applied immediately after an AC power up and will only affect the first
cooling or heating cycle that is called for, assuming the EasyTouch powers up in the ON
mode. All subsequent cooling or heating cycles begin upon demand per the normal
sequence.
11.2.2 Failsafe Level (Faults Not Detected / Faults Detected But Not Displayed / Faults Detected
and Displayed / Faults Detected and Displayed with Lockout;
Faults Detected
and Displayed with Lockout
)
This parameter controls the display and response to the various fault conditions. To protect
the air conditioning equipment, certain fault conditions trigger a Lockout. A Lockout occurs
when the control shuts down and will not automatically restart until the power (button) on the
display is cycled. The detection and the display of faults are also controlled by this parameter.
