When the sensor for control is returned to service, the ACS-UIT2 signals the alarm has been cleared,
returns the circuit to its normal control mode, and records both of these events.
Options: Power On or Power Off
Default:
Power On
Ambient Override:
The ambient override allows you to turn off the system when the ambient
exceeds a pre-established temperature.
Range:
40ºF (13ºC)–100ºF (38ºC)
Default:
55ºF (13ºC)
External Override:
The dry contacts from a BMS system or external device may be assigned to the
circuit to de-energize the circuit to save power when it is not needed. All temperature and system
alarms are still active. Refer to Appendix 5.3.
Schedule:
Tapping on this button will bring up the Scheduler. See Appendix 5.2 24/7 Scheduler on
page 127 for more information.
ASSIGNING RTDS
Tap Setup|RTDs window to assign RTDs after the control mode and parameters have been set.
In this mode you have the option of setting up to four RTDs for floor sensing. For detailed
information on the Setup|RTD window refer to 2.2.3 Assigning and Sharing RTD Control and
Monitoring on page 30.
Input from an external dry contact may also be assigned to override the system. Refer to Appendix
Section 5.3, page 130 for further details.
