Below is a procedure outlined to make the thermostat the primary sensor for heat cycles - I call this concept - THERMOSTAT PRIORITY. This does not rely on the thermistor probe (room sensor) to be properly calibrated to the surroundings to insure accurate heating of the room since the thermostat determines hi/low room temperature. There is another concept - I call it STOVE SENSOR PRIORITY. You can use this concept to make the thermostat a simple set back unit and this is how Harman recommends you do it. Downside is the fact that it will take some trial and error to get the room sensor properly calibrated so setting of 70 results in a room temp of 70. In my opinion THERMOSTAT PRIORITY is easier and more accurate long term since you won't need to fiddle with the room temperature potentiometer which can be prone to degradation over time and is not as exact as a digital thermostat.

^^^^In either case, setting the igniter switch to manual will result in the stove going to maintenance burn while the thermostat is not calling for heat or contacts open. If you want to run in Auto mode, the stove should shut down and start up nomally. ______________________________________________________________________________________________________
Just installed the 3301P wireless thermostat and it works like a champ. Installation couldn't have been easier
The folks at Skytech made it even easier than I anticipated. No cutting, no crimping, no splicing. Perfect!
Here are the install tips and a few pictures, prior to bundling and hard mounting everything.
The Skytech leads come with a female plug and an attached male plug "jumper". This makes everything a breeze.
(Harman plugs are red and Skytech plugs are clear plastic (in my case) - see pictures below)
Step 1 - Remove 1 temp probe lead (doesn't matter which one) from the Harman temp probe socket located at the back of the stove. Leave the other wire attached to the stove.
Step 2 - Break off the male portion of one Skytech control module lead (doesn't matter which one), preserving the female plug, and plug it into the slot previously occupied by the Harman probe wire.
Step 3 - Plug the remaining female lead from the Harman probe into the male portion of the remaining wire from the Skytech control module.
Step 4 - Set the room temp dial on the stove to a temperature higher than your remote thermostat will need to reach. In other words, if you plan to heat the room/area to no more than 75 degrees, set the room temp knob to 80-85 degrees to insure the thermostat maintains temperature control. You could max out the temp dial on the stove, but if the remote thermostat should have a problem one day, you don't want the stove to cook you out of the room. However, if you don't set the temp knob high enough, then the stove might throttle back before the thermostat call for heat is satisfied. After the stove has run for several hours and is up to temp, just pay attention to the thermostat and the status light on your stove. You'll always get the 4 blink status light at the end of every call for heat.
Now the Skytech control module is in series with one wire of the Harman temp probe creating a simple on/off switch for the probe. When the contacts open, the probe goes into fault (stove sees 105 degrees room temp) and the stove goes into 4 blink mode (if stove switch is on Auto or go into maintenance burn if the stove is set to manual).
The manual does a good job of explaining everything else with one exception. The swing temp is PLUS and MINUS of the set temperature. So, if your set temp is 70, then a swing temp setting of 2 will turn the stove on at 68 and off at 72. I thought it would be similar to a typical furnace thermostat where the setting would be max and the swing would be a minus only value. No big deal, just be aware before you program your temp settings. Currently, a 1 degree setting (3 degree total swing) seems to be the best balance between comfort and efficiency.
