Modulating Operation
Analog
Whatever the source of the control signal (BMS, room or duct humidistat, room or duct thermostat, or a
combination) the signal(s) should be connected between Common and Analog input 1, 2 and/or 3. These analog
inputs are configurable at step 1A “Settings” of the Controls menu (see page 17).
BACnet (network)
If the control signal is from a BACnet network, the RS485 A+ & B- should be connected to network (TB5). The
network control signal will have to be selected at step 1A “Settings” of the Controls menu (see page 17). Also
refer to step 1E “BACnet” of the Controls menu (see page 17) to setup the communication parameters.
