Using Comfort Mode
The settings on the HVAC system are optimized for operating efficiency and not for human comfort.
When working inside the shelter for extended durations, the site temperature can be temporarily adjusted
using the comfort mode setting.

2. Press Up or Down until the Cft is displayed in the bottom right of the screen and press Enter.
3. Press Up or Down to switch between Comfort and normal mode, press Enter to confirm.
To change the comfort mode setpoint, see “Changing the Setpoint and Free Cooling Humidity Limit”.
Important. If the HVAC system needs to cool aggressively to reach the comfort mode setpoint,
multiple WPUs may go into mechanical cooling.
