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.
