To not cause a potential problem with my warranty I installed the Coleman digital that Coleman recommends for my two systems. They are 12v thermostats not the cheaper home system thermostats that you can get at Lowes or Home Depot. These do work, but require batteries to operate since they aren't 12v thermostats.
The Coleman units aren't cheap, but I didn't want any potential warranty problems. They have been working fine now for 19 months.
