BAYSEN01ATEMPA
18-HD61D1-2
The BAYSEN01ATEMPA is a 10K ohm thermistor sensor
assembly used to sense outdoor temperature. Proper installa-
tion of this sensor is required for it to accurately sense outdoor
temperature.
Read this entire installation instruction before beginning the
installation.
▲CAUTION
!
Turn off all power to the heating and cooling equipment
before attempting to connect control wiring to Comfort
Control's subbase.

Installation - Location
Careful consideration of the following recommendations will
help to insure that the outdoor sensor provides accurate
readings:
1. Mount the outdoor sensor on the north facing side of the
building in an area where it is exposed to freely circulat-
ing airflow and out of direct sunlight.
2. Do not allow hot air from the attic or drafts from inside
exterior walls to bias the sensor's operation. Always seal
the hole where sensor's wiring passes to the outside of
the structure. Use non-hardening caulk, putty, or
insulation.
3. Avoid locations such as near dryer vents or close to, or
directly above, the outdoor unit where it would be
exposed to hot discharge air from the condenser fan.
4. Install the sensor a minimum of 12 inches above normal
expected snow accumulation.
Wiring
•Maximum length of field wiring to sensor is 200 feet.
•Minimum wire gauge is 18AWG.
1. Turn all power off to the indoor air handler or furnace.

2. Separate the control from the mounting base. Route
sensor wires through the large hole in mounting base.
3. Adjust length and routing of the sensor wires to reach
the roper terminals on the connector block on mounting
base. Strip only 1/4-in. of insulation from each wire to
prevent adjacent wires from shorting together when
connected.
4. Connect the sensor's wires to the proper terminals on
the connector block.
5. Push any excess wire back into the wall and seal the
hole to prevent air leaks.
Note:
Air leaks in the wall behind the control can cause improper
operation.
Control setup and checkout
1. Reinstall the control on its mounting base.
2. Turn ON power to the furnace or air handler.
3. Enter the Comfort Control's Installer Setup mode and
enable the Outdoor Temperature for display only or
for display and control. See the control's installation/
setup instructions for details.
4. After setup is complete, verify that the sensor and
control are operating properly. The outdoor tempera-
ture should display with no service icon present.

Since the manufacturer has a policy of continuous product and product data improvement, it reserves the right to
change design and specifications without notice.

Troubleshooting
Display shows two dashes when outdoor
temperature button is pressed.
Sensor not connected properly, shorted or open
wiring or sensor.
Control displays very high outdoor temperature. Wires are touching (shorted together) or sensor is
damaged.
Control displays very low temperature. Improper wiring connection to sensor or sensor is
damaged.
The sensor and the sensor field wiring can be checked by measuring the resistance at the control's
subbase with the control removed. See Table 1 for proper values. If the resistance value is within +/- 5
% of Table 1 values, the sensor is good.
