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 of the 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 line up 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.
Uses:
1. External Temperature Sensing
2. Refrigeration Monitoring & Control
3. Dry Contact Alarm Interface

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.
