The TA1 is a wired thermostat accessory either used as an external temperature sensor for a thermostat or to provide an input for an external dry contact relay. It is compatible with Pelican's TS200, TS200H, TS250, and TS250H models. Connecting the TA1 is simple and provides a wide range of input flexibility. The most common applications for a TA1 include: averaging out the temperature between the sensor and a thermostat, as an external temperature probe for a thermostat, as a mounting for a TA1 in a cold box for temperature monitoring, as an input for a supply air temperature probe, or as a dry contact input for an occupancy sensor. Only one TA1 can be used per thermostat.
Temperature and Alarm Sensor (TA1)

Online monitoring with full visibility
The TA1 is built to be a flexible, inexpensive addition to your Pelican thermostats. It can detect temperatures in the range of -20 deg. F to 180 deg. F (depending on the external probe used). Alternatively, use it to accept a dry contact relay for either sending alarms or for setting a thermostat temperature based on if a space is unoccupied from an Occupancy sensor.
Simple to install
The TA1 only requires three wires to connect to your Pelican thermostat. The TA1 can be placed up to 500 ft. from your thermostat using standard unshielded thermostat wire. In applications where there are only two wires to a probe: simply install the TA1 next to your thermostat and wire the two external wires from the probe into the TA1's 'T' input. The TA1 is compatible with any 10K Type II thermistor.

External probe input
The TA1 comes with an internal probe, but many times the temperature you want to detect is in a supply duct, outside, or on a pipe. Pelican offers multiple certified probes to combine with a TA1 for additional temperature detection options.

Save energy in unoccupied spaces.
The TA1 can accept a dry contact input from any third-party occupancy sensor. When the occupancy sensor detects a room is empty, the TA1 automatically adjusts the thermostat temperature to a set point to save energy. Ultimately saving you money - your HVAC only runs in occupied spaces.

Included with the TA1 is a removable temperature probe. Either use the provided probe or the TA1 can accept any 10K Type 2 external temperature probe. This input can also be used to accept a dry contact relay for alarming.
Online Monitoring
The TA1 is Internet enabled once connected to a Pelican thermostat. Monitoring temperatures or viewing whether a space is occupied is as simple as pulling out your smartphone.
Temperature Detection and Averaging
Connect a TA1 to a Pelican thermostat for external temperature monitoring and temperature averaging. Monitor conditioned spaces, duct temperatures, discharge temperatures, or a cold box. The TA1 is flexible for many applications.
Dry Contact Input
The TA1 can accept any type of dry contact input. Use the Pelican Web App to configure the TA1 to send an alarm if the contact opens or closes.
Occupancy Sensor Input
A TA1 can accept a dry contact occupancy sensor. This configuration allows you to set your Pelican thermostat to automatically adjust temperature settings based on occupancy.
Safe Range Notifications
With Internet connectivity you receive notifications if the TA1 detects temperatures out of a normal range. This allows instant access to information such as whether your cold box is getting too warm. Or, if your HVAC unit discharge temperature is not hitting a target.
Historical Trend Data
Every TA1 tracks trend data in real-time so you can visually see exactly how your spaces are operating at any moment of the day. This data is accessible Online for up to 2 years for every TA1. The TA1 also tracks when a space is unoccupied if used with an occupancy sensor.
