INSTALLATION
9. Connect wires to thermostat terminals as required. Refer
to wiring diagrams Fig. 4 thru 7 for proper wiring.
10.Apply system power and confirm that thermostat display
is on and SYSTEM mode is OFF. Press SYSTEM button
to OFF if necessary.
11.Enter the configuration as described in Thermostat
Configuration Menu on page 10. Configure the thermo-
stat for system operation. While in the configuration
menu, enable the indoor remote wireless sensor (item 4)
by changing OFF to ON.
Confirming Communication of Remote
Sensor to Thermostat
Before finding a good location to mount the remote sensor,
confirm that the thermostat is receiving the remote sensor
signals consistently and at the best strength possible.
Reliable Communication: While the sensor is in the Learn
Mode, to be sure the thermostat and sensor have good commu-
nication. The thermostat receiving icon and the sensor transmit-
ting icon will appear and turn off at about the same time. The
thermostat will display SIGNAL and the strength of the signal.
3 bars indicates a strong signal and the most desirable, 2 bars
indicates a medium strength signal and 1 bar indicates a weak
signal which is acceptable if it can not be improved. The
thermostat display will also show the temperature sensed by the
remote. The thermostat should receive 6 signals in 1 minute and
the signal strength should be 3 bars if possible.
1. Remove the battery tag from only the remote sensor. The
battery tag must still be in the thermostat. The remote sensor
will begin transmitting a signal once every 10 seconds for
one hour.
2. Place the remote sensor on the thermostat and check that
the thermostat is receiving signals from the sensor. Confirm
that the sensor and thermostat have reliable communication
as described above in Reliable Communication.
3. Move the remote sensor to the room where it is to be
installed. Do not mark a mounting location or drill holes yet.
4. Have someone hold the remote sensor at the location
selected for the remote sensor. Hold the remote sensor on
the left side to avoid interference with the transmitting
antenna on the right side of the sensor.
6. Return to the sensor and confirm that reliable communica-
tion with the sensor can be established again as described
in Reliable Communication. Have the sensor moved, if
necessary to improve the signal strength if it is not a consis-
tent signal with signal strength of 3 bars.
7. Once the ideal position for the sensor is determined, mark
mounting holes using the sensor base as a template (Figure
3). The batteries will have to be removed to access a
mounting under them.
8. After the sensor is firmly attached to the wall and the batteries
are reinstalled, the remote sensor will begin transmitting
again for one hour. Return to the thermostat and once again
confirm that communication is still good as described in
Reliable Communication.
Battery Location
The sensor requires 2 "AAA" alkaline batteries. Batteries are
included at the factory with a battery tag to prevent power
drainage. The battery tag must be removed to engage the
batteries. For best results, replace batteries once a year with
new premium brand alkaline batteries such as Duracell
®
or
Energizer
®
.
Electric/Gas Switch (Fan Option)
The ELEC/GAS switch on the thermostat (Fig. 1) is factory
set to the ELEC position. In this position, the thermostat will
power the circulator fan on a call for heat. Electric heat
systems may require the switch to be in the ELEC position.
If your system does not require that the thermostat power the
circulator fan, this switch should be set to the GAS position.
Typically, gas and oil heating systems do not require the
thermostat to power the circulator fan during a call for heat. If
your heat is gas or oil, the switch should be set to the GAS
position.
When the thermostat is configured for Heat Pump, the
thermostat will always power the circulator fan on a call for
heat in the HEAT mode. The ELEC/GAS switch must be set
to match the type of Auxiliary heat your system uses for
proper operation in the EMERgency mode.
Typical wiring diagrams are provided below for the following systems:
Single Stage Heat/Cool systems
Multi-Stage Heat/Cool systems (No Heat Pump)
Heat Pump system, one compressor or one speed compressor with Aux. Heat
Heat Pump systems, two compressors or two speed compressor with Aux. Heat
Refer to the equipment manufacturers instructions for specific wiring information. After completing the connections configure
the thermostat in the Installer Configuration Menu to match your system type.
