Chapter 4: E2 Controller

When fans are not linked, the controller adjusts the speed of each fan as necessary for that zone to meet the supply air temperature setpoint. When the system is in the dehumidification mode, the fan speeds are automatically linked and controlled to the same speed.

4.5.4.2 Alarm Setpoint Screens

Figure 4-29. Alarm Set screen.

You can access the Alarm Setpoints screens from the Control menu. These screens enable the high and low temperature and humidity alarms, adjust their setpoints, and compare them to the control setpoints and to the current system-level operating data derived from the sensor inputs.
