VCCX2 Controller Technical Guide
Multiple Digital Space Sensors
Multiple (up to 10) digital space sensors can be connected to the
VCCX2 Controller in applications where multiple spaces (not
utilizing VAV boxes) could be served by a single unit. These
sensors can be either the E-BUS Digital Space Temperature
Sensor or the E-BUS Digital Space Temperature/Humidity
Sensor.
The VCCX2 can be configured to use temperature (high and
low) to determine the Cooling or Heating Mode or average
the space temperature values and use that value to determine
the mode of operation – in both cases relative to the VCCX2
Space Temperature Setpoints. It would use the highest humidity
value relative to the Space Humidity Setpoint to initiate
Dehumidification Mode.
The digital sensors each need to be configured with unique
addresses (#1 -10) for this operation. In this arrangement, only the
sensor at address #1 can utilize the slide adjust. All push-button
overrides on the sensors will function. Each sensor can have its
own calibration offset, if required.
