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.

Solid Green RS-485 communication is established
and the module is communicating with
thermostat.

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 Auxiliary Relay Connections section
on next page for wiring examples.
C24V 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 RS-485
Connections diagram for more information on wiring.

When making connections, follow the guidelines set below to ensure a
safe and secure connection.
Use the diagrams below when making the power connections be-
tween the thermostat and CLI-AUX3 climate module.
Use the diagrams below when making the RS-485 connections be-
tween the thermostat and CLI-AUX3 climate module.
– Power can be daisy-chained between modules.
– The cable lengths vary depending on the size of the wire. See the
specifications table on page 1 for more information.

Refer to the following documents located on the Savant Customer
Community for additional information.

– Multistat Thermostat with Touchscreen QSG (009-1593)
Additional Information
1. With a small slotted screwdriver, turn
the screws on the connector coun-
terclockwise (CCW) until the silver
crimps open enough to slide a wire
into the square slots.
2. Strip back insulation on each wire to
/ inch and insert the stripped wire
into the proper connection.
3. Turn the screw clockwise (CW) until
the crimps tighten around each wire.
Tug on each wire a bit to verify they
are secure.

– The diagrams above use Aux 1 connections. Wiring of the Aux 2
and Aux 3 ports are the same.
– The auxiliary relay does not have a voltage connected to it. There-
fore an external source connected in series with the equipment is
required.
