Unit Ventilator Controller Installation Overview
Figure 8 shows one possible installation of the Unit Ventilator Controller. Inputs,
outputs, ducts, and heating or cooling units have been marked for your
convenience.
Note: Not all possible sensors are shown.
Inputs
The Unit Ventilator Controller has six universal inputs. You can configure
universal inputs by using the Unit Ventilator Controller configuration wizard.
Universal inputs are configured as either:
• analog inputs sensing either current or voltage, or
• digital inputs or 10k ohm resistance inputs
Note: Because the Unit Ventilator Controller can connect to a maximum of six
sensors, you may want to connect some sensors using the LONWORKS
network. All valid network inputs have priority over hardware inputs.
