TIME DELAY ON 2 STAGE ECONOMIZING
When in economizing mode this is the delay for the high speed fan to try to
satisfy the call for second stage cooling before the first stage mechanical
cooling is enabled.
The checkout for the damper minimum positions is based on the system.
See Table 12.
Positions damper to the full open position.
Exhaust fan contacts enable during the DAMPER OPEN test. Make sure
you pause in this mode to allow for exhaust contacts to energize due to the
delay in the system.
Positions damper to the fully closed position
Closes the Y1---O relay (Y1---O).
See CAUTION on page 41.
Closes the Y2---O relay (Y2---O)
See CAUTION on page 41.
Energizes the AUX1---O output. If AUX1---O setting is:
S NONE --- not action taken
S ERV --- 24 Vac out. Turns on or signals an ERV that the conditions
are not good for economizing but are good for ERV operation.
S SYS --- 24 Vac out. Issues a system alarm.
Closes the power exhaust fan 1 relay (EXH1)
