Which thermostat

Doug ClarkDoug Clark Member Posts: 7
I would like to put a 2 stage heating (Boiler and Oil furnuce as secondary) 1 stage cooling plus fan in a home. The thermostat would run the radiant in a large room (using floor sensor) plus being centrally located in about the center of the house would use it to run the oil on the nights that it would need a boost, I was thinking of using a duct sensor for this. The reason for the secondary heat is a long one but will explain if needed. Would also like to run air conditioning from same thermostat and summer fan when not heating. I am currently using Tekmar for thermostats in the house (used to operate zone valves going through a Taco zone valve contoller)and would like to continue with the product as it is nearly bullet proof and simple to operate. My question. Is there another unit I could use instead of the Tekmar 545 or is that it in the Tekmar line. I maybe open to other manufactures if that is the case.
