When a remote controller is set to factory setting, the system operates according to the main unit Dip switch settings. When the remote controller settings are changed
from the defaults, the system operates according to those settings. (The main unit switch settings are overridden.)
* 2 If two remote controllers are used, these settings can be performed only for the “main” remote controller. These settings will be skipped for the “sub” remote controller
and may not be modified. The designation of main and sub remote controller and are determined automatically upon main unit power-up. The remote controller for
which [5] and [6] are displayed in the Function Selection mode is the main remote controller.
* 3 Clock use must be set for Weekly timer and Night purge operation.
* 4 Applies only to the following functions:
[Supply fan], [Exhaust fan], [Start up power supply and exhaust]
* 5 Indicates Dip switches in the Lossnay control box.
* 6 For the Lossnay models without those functions, those setting items will be nondisplay.
