Blinking Green RS-485 communications is not estab-
lished. Once power is applied, it can take
up to 20 seconds to establish communi-
cations.
HELPFUL! If communications was es-
tablished and subsequently lost,
the LED will stay solid for about 1
minute before it starts blinking.
Solid Green RS-485 communication is established.
Module is communicating with thermo-
stat.
B
Climate Relays - The relay outputs on this module operate
similar to the relays of the same name on the thermostat.
Connect the relay outputs (W1, W2, Y1, etc) to the appropri-
ate connection on the HVAC system equipment. Refer to the
Relay Connections section when making the connections.
Climate Relay LEDs - The LEDs associated with each relay
will light when the relay is energized and be o when relay is
in its idle state.
C
Auxiliary Relay - An additional relay is available for con-
trolling external HVAC equipment such as a vent damper,
humidifier, or dehumidifier. Refer to the Auxiliary Relay Con-
nections section on the next page for wiring information.
D
24V AC input - To power the module as well as supply power
to the W1, W2, and O relays, connect a 24V AC transformer
between the C and RH terminal. To supply power to the Y1,
Y2, and G relays, add a jumper between the RH and RC ter-
minals or connect a separate 24V AC source between the C
and RC terminals. See the Power Connections section on next
page for wiring information.
ARS-485 Port - As shown above, the right three pins connect
to the RS-485 terminals in thermostat. Refer to the RS-485
Connections section on the next page for more information.
