Digital t-stat for a 154bh

Our 154bh has an analog t-stat for the heater only. It works fine but is difficult to set to a specific temperature (or temperature range even). I'm a certified electrician so wiring and terminations aren't a problem but I have limited knowledge of HVAC controls.

Does anyone know of a digital t-stat suitable for this application? What should I look for when shopping around for t-stats? And wires are what when I pull the old unit off the wall?

This is an easy update. I used the following Honeywell heat-only digital thermostat in our 195RB Baja:

Honeywell Pro 1000

Here's a couple of shots showing wiring and finished installation. We've been happy with the update and it's worked well for us:

Be sure and tape the hole behind it with some duct tape to keep the thermostat accurate.

Love the Honeywell https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Batteries keep it set to temp without resetting it each time the power is off or during travel.

Extremely simple to change over and works better at holding a set temp.

Wow that was easy!

I'm gonna go two for two..

How about a stubby antenna for the radio? The one that's up there is probably 3 feet tall and is getting whipped around like crazy by my neighbors low-flying palm tree when I pull the trailer past.

Ok I got the t stat but it looks like I've got 2 wires in the trailer (according to ttavasc) and three terminals on the new t stat (power, 24v common and heat pump) since my trailer only runs on 12v and I see some notes about 24v common being optional am I to assume that one of the wires in the trailer is power and the other is heat pump?

Which is which or does it not matter?

Nevermind I figured it out. R for red, W for white...

Any ideas on that stubby antenna I asked about?
