Most Liked Positive Review
All RV owners need this Product.....!
It's a lot better than the old mechanical spring/magnetic type w/contacts..! My RV has the Propane Furnace as most RV's Do. Contacts closed, you got heat... Contacts Open, No heat..! There is no transition between heat/No heat, it's either On or Off..! Even w/thermostats Anticipation. The Honeywell Pro 1000 makes heating an RV so much more comfortable and a steady warm climate. Metal sheathing RV's tend to heat up like an oven, holding the heat from the Sun, one can turn the Heater Off by the flick of a small switch...
My only problem is the Manual is not real clear about "Setup" pages 6 & 7... Hold the both ARROW keys down till screen changes, adjust and set, then go on to the next "Setting"... The Problem is Manual does Not state what each setting is for... I even talked the Manufacturer, they didn't help either... That's the only bad thing about it...!

Unsure
I purchased several to replace my Viega stats. Just three wires and it states you can direct wire and not require the batteries but so far i have two installed and both require the batteries to work.
