4.2 TEMPERATURE CONTROL
There are several options available on CLASS UNIT units to ensure a comfortable
temperature. The options are controlled either via supply or extract air temperature.
Supply Air Temperature
Supply temperature control is the default setting. This involves keeping a constant supply air temperature without
consideration to the load in the premises. The supply air temperature is measured on sensor T5.
Extract Air Temperature
The default temperature control can be changed to Extract temperature control via the advanced setup.
The extract air temperature is measured on sensor T2. Extract air control involves keeping a constant temperature in
the extract air duct (premises), by controlling the supply air temperature. This provides a uniform temperature in the
premises regardless of the load. The internal sensor T2 can be replaced with the optional external room temperature
sensor (CID370042).
