Quick Installation and Startup Guide
Insert a small coin
(dime) in the release
slot located on the
bottom of the
thermostat and gently
twist the coin to
release the thermostat
from the subbase.
Before mounting
the thermostat
subbase to the
wall, pull the
wires from the
HVAC unit
through the wire
access hole.
Mount and level
the subbase
using the
furnished
hardware.
After all wiring is landed, attached the thermostat to the subbase and apply 24 Volt power.
Land the remaining HVAC wires to the thermostat terminals based on the specific equipment configuration. If an indoor or outdoor remote sensor is used, wire the sensor to the T T terminals.
The sensor wiring must be a separate 18-2 cable and should not exceed 200’ in length from the sensor to the thermostat.
Refer to the thermostat Installation Manual for Advanced Installer settings that might be
required for the specific equipment applications as well as confirming that the baud rate is
set at 19.2 and the Modbus address is set at 01.
To simplify installation,
the transceiver comes
pre-wired to the
thermostat terminals with
leads for the HVAC unit
24 Volt hot and common.
Use wire connectors to
secure each lead to the
HVAC unit 24V ‘R’ and
24V ‘C’ wires. Land the
remaining HVAC unit
wires to their proper
terminals. Dress all wires
so that they do not come
in contact with the
thermostat PC board.
Set the system slide switches to match the
HVAC equipment application:
* For heat pump systems that energize the reversing valve on a call for heating (B), turn switch 4 ON.
SWITCH 6 MUST BE OFF AND SWITCH 8 MUST BE ON
Use the provided
6 transceiver log
to document the
serial number
located below the
bar code on the
back of the
thermostat
subbase. Also
note the
thermostat
location.
Turn the two
Modbus
configuration
slide switches
to ON.
