Description of Operation
Rapid Cool
(Optional)
2
The Rapid Cool light flashes green when the unit is executing a Rapid Cool sequence. The Cool light will also flash green dur-
ing a rapid cool sequence. After the Rapid Cool sequence is complete, the unit stops and the Rapid Cool light remains green
to indicate the completion of the sequence. See the Rapid Cool Button section for a description of the Rapid Cool function and
operation. See the Program Menu section for instructions on how to enable or disable this feature.
Communications
(Optional)
2
The Communications light flashes green when the unit is properly transmitting and receiving a communication signal. See the
Program Menu section for instructions on how to enable or disable this feature.
Remote Heat/Cool
(Optional)
2
The Remote Heat/Cool light is on and yellow when this option is enabled. This feature allows the heating and cooling to be
turned on and off by remote contact closures. Switching a contact from open to close activates the heat or cool function as-
signed to the contact. Switching the contact from closed to open deactivates the individual heat or cool function assigned to the
contact. When enabled the controller does not perform any heat or cool functions and relies exclusively on the external contact
closures for these functions; however, the unit maintains all warnings and safety functions. From the factory, the Remote Heat/
Cool feature is disabled. See the Program Menu section for instructions on how to enable or disable this feature. Do not intro-
duce any external voltage to the Remote Heat/Cool contacts; this will result in damage to the controller.

The Program Mode light flashes yellow when the control system is in the programming menu.
