Key Benifits


saving budget

Cost effective

TN-S322CA1 is the best choice in your cost effective solution while you can take advantage of it's special options.


High power control

High current relay

High current, 30A relay contact allows to powering up high power compressors and heaters with peace of mind.



Easy to use

Simple installation and easy menu parameters configuration made this device very easy to use and user friendly.


Yes, this device can be used to control heating in applications such as greenhouses or incubators.
For this purpose, various other models have been prepared and placed at your disposal. This model is suitable for use in fanless freezers.
The performance of this thermostat is guaranteed to drive the compressors up to 1.5 hp directly. To drive more powerful compressors, it is necessary to use an external relay or contactor next to the thermostat.
