Four-stage gas heating is enabled when zone sensor, Discharge Air Control, or fresh air tempering mode is selected. (Available when using the CS8500 thermostat or
when connected to Building Automation Systems using BACnet, LonTalk, or S-Bus protocols.
HIGH ALTITUDE DERATE
Units may be installed at altitudes up to 610 m (2000 feet) above sea level without any modification.
At altitudes above 610 m (2000 feet), units must be derated to match gas manifold pressures shown in table below.
At altitudes above 1372 m (4500 feet) unit must be derated 2% for each 305 m (1000 feet) above sea level.
NOTE - This is the only permissible derate for these units.
