STAGE 2 OPERATION
Stage 2 can be configured for cooling, heating, mist or recirculation. Use
internal dipswitches # 4, 5 and 6 to select a configuration.
1. COOLING
Stage 2 has two modes of operation when used for cooling: (i) Continuous
Mode — used when cooling is required to lower the room temperature; (ii)
Minimum Ventilation Mode — provides oxygen to the room and reduces
humidity levels when cooling is not needed.
Minimum Ventilation Cycle
When cooling is not required, Stage 2 fans operate according to the
minimum ventilation cycle.
