Commissioning Guide for VPQ-2
Page: 4 of 10
Rules
1. Each power pack will power up (12) diffusers. It has (2) outlets; you may daisy-chain up to (6) diffusers per outlet.
The last diffuser in each run must have a termination plug installed. Every diffuser connected to a power pack is
part of the power pack’s local network.
2. A USB module or MCM is REQUIRED if any diffuser is to be configured as a slave. If all diffusers are masters,
they can be configured with the thermostat.
3. A “loop” is defined as a thermostat and any diffusers it is connecting; master or slave.
4. The master diffuser is the unit to which the thermostat is connected.
5. Without an MCM, any diffuser loop is limited to (12) diffusers. This means that you may have (1) thermostat which
controls (1) master diffuser and (11) slave diffusers, all connected to the same power pack. The MCM can connect
to up to (4) power packs, which will allow any diffuser network to be expanded to (48) units.
6. The MCM may be addressed via an IP address for easy diffuser network programming.
