Configuring The IMT Power Source
The IMT550c can be powered from different sources presented on the following
Ethernet CAT5/5E/CAT6 interface.
HVAC - 24VAC is power from the HVAC system which requires RH and C to
both be connected to provide power to the thermostat. (IMT550c and IMT550w)
EPA - Proliphix Ethernet Power Adapters (EPA) are multi-port power injectors
capable of supplying power to either two (EPA-20) or six (EPA-60) Proliphix
Network Thermostats. (IMT550c and IMT550w)
PoE - A Power over Ethernet (PoE) source is an Ethernet router, switch, or
mid-span device that complies with the 802.3af Power over Ethernet standard.
(IMT550c only)
Figure 2 shows the four power sources located at the upper right of the IMT. The
switches are highlighted in yellow in the accompanying figure.
Figure 2 Power Sources
Table 2 shows how to configure the IMT for different power sources.
Do not connect to both Power over Ethernet and HVAC power at the same time.
