A
Blinking Green
Communications with thermostat is not
established (RS-485). Once power is
applied, it can take up to 20 seconds to
establish communications.
HELPFUL!
If communications was es-
tablished and subsequently lost,
the LED will stay solid for about 1
minute before it starts blinking.

RS-485 communication is established
and the module is communicating with
thermostat.
B
Aux 1-3 Relay Inputs
- Each Auxiliary port (Aux 1, Aux 2, Aux
3) contains a relay that can toggle between a normally open
and normally closed terminal. These relays can be used to
control external equipment such as a vent damper, humidifier,
or dehumidifier. See the
section
on next page for wiring examples.
C
24V AC input
- Connect 24V AC from HVAC transformer or
similar to power the module. Input power is an AC signal so
polarity is not observed.
A
RS-485 port
- As shown in the image above, the right three
pins connect to the RS-485 ports in thermostat. No connec-
tions are made to the leftmost 3 pins. Refer to the
diagram for more information on wiring.
