Standby and Cascade
Cascade is possible in Teamwork Mode 1 and 3 only.
Line S508 Cascade Units has the options of Yes, Cool / Heat, Cooling, Fan
Yes—Based on a call for heating, cooling, humidification or dehumidification. TW1
Cool / Heat—Based on a call for heating or cooling. Teamwork Mode 1
Cooling—Based on a call for cooling. Teamwork Mode 1 
Fan—The only selection available for Teamwork Mode 3; not available in Teamwork Mode 1. Uses 
fan control deviation to stage on standby unit fans / cooling. Fans stage serially according to the 
system fan control band and temperature control is based on the local supply deviation. (Fan 
proportional band / number of connected units)
The standby unit will remain On for the time set in the parameter. The default is 30 minutes; range is 
from 2 to 360 minutes.
Standby units will start if an alarm occurs in one of the operational units. If the standby units are 
cascaded or in Teamwork Mode 3, they will also start and work with the regular operational units if 
the temperature or humidity cannot be controlled by the operational units; before a high or low 
temperature / humidity condition occurs. Cascaded units are switched Off again as soon as the 
temperature / humidity returns back to normal.
The master unit defines its proportional band according to the number of available units (see 4.2.3 - 
Teamwork Mode 1).
When a standby unit receives a request for full heating or cooling from the master unit (see 3.3 - 
Temperature Control), it will respond to the request after its control delay.
NOTE
Cascaded units are not included in the calculation of the average temperature / humidity.
