I installed the Coleman Mach unit you can purchase on Amazon for about $70. The unit is a direct wire for wire swap and mounts directly where the old unit did. It will control within 1 degree. The unit works very well. Our original analog would swing in temp almost 10 degres. This should be an option or standard equipment, especially on the Emerald editions...if you decide to go with this unit, verify wiring before installing... best of luck...
