10 Proliphix Thermostat Installation Guide, Release 1.0
Part No. 600-01000-100
Installing and Wiring the Thermostat
Mounting the Thermostat into the Base Plate
The Proliphix thermostat contains jumpers to configure the HVAC power settings.
The power settings determine which HVAC power source (RH or RC) is configured to
turn on each HVAC system (cool, heat and fan). Most applications use only RH
power. The Proliphix thermostat is shipped from the factory with the “RH Only”
configuration.
Table 5 lists the possible HVAC power configurations. RC and RH are connected with
J1 inserted.
The NT100e/NT120e/NT125e can be powered from different sources presented on the
following Ethernet CAT5/5E/6 interface:
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.
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.
Table 6 shows how to configure the NT100e/NT120e/NT125e for two different power
sources.
Figure 5 shows the location of the jumpers on the thermostat circuit module. The
jumper in J2 supports an Up (POS1) or Down (POS2) position. The example in
Figure 5 shows the J2 jumper in the Up position. If necessary, move the jumper
downward to the POS2 position.
