Sentinel Controllers
Sentinel has taken digital accuracy and combined it with ease of use. Their one-touch functions make using their control systems so easy, reading the manual may not be necessary. Many of their products serve more than one function (such as a heating or cooling controller) making them extremely flexible and capable of being used in many situations.
All Sentinel controllers are designed to maintain a very high degree of reliability while performing critical functions. In some cases, their innovative designs are so unique — there really are no other products available for comparison.
