These are replacement sensors for the LA-277 controls.
My name is Ronnie and I have my own small HVAC business. I have a new equipment install sold for new Cond and matching Evap coil but the furnace is still in good shape. I used to work for my dad and when doing so he introduced me to your product and we sold and installed a module and motor for a customer who saved the furnace and upgraded the cond and evap coil with your product and absolutely loved the product. So when selling this job the customer is very interested in the variable speed motor for indoor air quality and energy efficiency, I have been able to sell them on the exact same type of job! I am wanting to purchase a ECM 4 motor and module ASAP, please let me know how I can make this happen? Thanks and have a good day.
