FS-TA1 Temperature and Alarm Sensor
Installation Guide
Caution
Failure to follow these instructions can damage the product or cause a hazardous
condition. Disconnect power during the installation of this product. All wiring must
conform to local codes and ordinances. The FS-TA1 sensor is designed for use with 24
VAC Founten thermostats only. After installation, if the FS-TA1 Sensor does not show up
on your Founten Site Manager you will need to contact Founten Support and request a
thermostat software upgrade.
Mount the back plate ofthe FS-TA1 sensor to a flat surface. Position it so that wires can be
fed through either the oval opening in the back or the small opening on the bottom of the
FS-TA1 sensor. Drill 3/16" holes into the wall at the provided mounting locations on the
FS-TA1 sensor. Insert anchors into the wall and attach the back plate to the wall using the
included mounting screws. Follow the wiring instructions on page 2.
After the FS-TA1 sensor is mounted simply lineup the front cover to the back cover and
snap into place. To remove the front cover from the back plate,use a flat head screw driver and
lightly twist in the provided slots on each side of the FS-TA1 sensor.
The Temperature and Alarm sensor is
an add-on accessory to the Founten
FS-STAT-32AC and FS-STAT-32ACH
Thermostats.

1. External Temperature Sensing

Remove Wiring Module from the
FS-STAT-32AC(H) thermostat. Install
Wiring Module inside of the air handler.
Refer to page 4 of a FS-STAT-32AC(H)
Installation Guide.
Some installations may have limited in-wall wiring. Use this configuration if no Data Wire or
Common Wire is available. A common application would be to monitor supply air temperature
with limited wires.
Login to your Founten Site Manager Web Application. Select Admin > Thermostat Setup for
the thermostat which has the newly attached FS-TA1. Scroll down until you see a category
labeled “Wired Sensor”
Select the correct Function for your FS-TA1 sensor:
– “Temperature” to use the FS-TA1 sensor instead of the thermostat’s internal temperature
sensor or to allow averaging between the FS-TA1 sensor’s temperature sensor and the
thermostat’s temperature sensor.
– “Alarm” to use the FS-TA1 sensor as an interface for a Dry Contact alarm input. Select
whether a notification should be sent when the contact is opened or closed.
– “Temp Monitor” use the FS-TA1 sensor as a stand alone temperature monitoring device.
(ie. supply air temperature or outside air temperature monitoring).
For additional assistance visit www.Founten.com to request support.
Connect the R, C, and D terminals from the
Wiring Module to matching terminals on the
FS-STAT-32AC(H).
Connect the R, C, D terminals from the
Wiring Module to the matching terminals on
the FS-TA1 sensor.
Note: The sensor can then be used for any one of
the three examples shown on page 3.

The FS-TA1 sensor requires 3-wires for power and communication with a
FS-STAT-32AC(H); as shown in the diagram above. In many situations you will be able to
simply mount the FS-TA1 sensor on a wall and use the provided 10K internal temperature
sensor to detect the temperature at the desired location.
Follow the guide on page 3 for alternate installation options for the FS-TA1 sensor. The
FS-TA1 sensor can be installed at a maximum distance of 500'from a FS-STAT-32AC(H).
A 10K external temperature probe can be connected to the FS-TA1 sensor up to 100' away.
We recommend using a Founten certified external temperature probe. Contact your local
Founten distributor for assistance.

For installations where 3-wires already exist or can be run from
a FS-STAT-32AC(H) thermostat to the FS-TA1 sensor. Mount
the FS-TA1 sensor directly on the wall. Connect FS-TA1
sensor’s D, C, and R terminals to matching terminals at
FS-STAT-32AC(H). 500' maximum distance.
Applications:
– Detect temperature inside of an enclosed refrigerator or
freezer.
– Install the FS-TA1 sensor in the conditioned area with the
thermostat placed in a secure, non-visible location.
Remove the internal temperature sensor from the “T” terminal
of the FS-TA1 sensor. Connect the external temperature
probe to the FS-TA1 sensor’s “T” terminal. 100' maximum
distance.
Connect the FS-TA1 sensor’s D, C, and R terminals to
matching terminals of the FS-STAT-32AC(H).
The following wiring options should be used to determine the proper wiring approach for
your application. This guide shows the most common configurations. Contact Founten for
assistance with configurations not shown on this guide.
