S515 Cascade Units—Allows units to activate in Standby mode if the room temperature cannot be
maintained by the active units. If Yes is selected, the cascaded units can perform all functions when
activated from standby. This parameter can also be set for Cooling Only or Cool / Heat / Fan
(available in Teamwork 3 only).
S516 Cascaded Units Delay—Sets the delay time to stage on each unit as they are staged on during
S516 Cascaded Units Delay—Sets the delay time to stage on each unit as they are staged on during
increased demand. When the first unit is started and the cooling request is high enough to start, the
timer is started; once the timer has expired the next unit will start. The range is 0-30 minutes. The
default is 5 minutes.
S517 Cascaded Units Quick Start—Sets a delay to the staging on each unit after a power cycle of
S517 Cascaded Units Quick Start—Sets a delay to the staging on each unit after a power cycle of
the master unit. This is used to get the units to start faster after a power cycle and use this parameter
instead of S516. When the master unit is started and the cooling request is high enough to start, the
timer is started; once the timer has expired next unit will start. The control will not revert to S516
until all required units have been restarted in Cascade. The range is 0-30 minutes. The default is
2 minutes.
S518 Cascaded Units Control Delay
S518 Cascaded Units Control Delay
Teamwork Mode 1: Mode C: Once the unit was started, the fanspeed control will start
immediately, but the cooling / humidity control will be delayed by the value set in S518 Cascaded
Units Control Delay. Mode B: the S518 timer is ignored; a cascaded unit starts control w/ no
delay.
Teamwork Mode 3: All Modes: When the cascaded standby unit was started, the normal unit
Teamwork Mode 3: All Modes: When the cascaded standby unit was started, the normal unit
control is delayed by the value set in S518 Cascaded Units Control Delay. During this delay, the
fanspeed control and the cooling control use the shared system values (based on AVG or MAX);
heat, hum and dehumidification is disabled. When the S518 timer has elapsed, the unit
transitions to normal unit control, which is depending on the operating mode. The range is 0-30
minutes. The factory default is 5 minutes.
