thermostat fan

[jpaskell]

Good morning all, I have been fortunate enough to be able to RV for the last 15 years. I found that I have NEVER used the low heat setting on my thermostat.

Has anyone used this setting and if so, when do you use "low heat". Not sure what I'm missing.

Thanks,

Jim

Sorry, I meant to say low FAN setting. High for cooling and the heater has it's own fan speed. Or so it appears.

Picture of thermostat?

I don't know if I've seen a variable speed furnace fan.........

I just use the low fan setting if we want some air movement, but don't need much cooling at night.
(Standard coleman wall thermostat in Rockwood fiver, which I replaced with the digital version)

However, it may get used less from now on, since I'm about to install a MaxxFan deluxe, to replace the bedroom vent, this weekend (weather permitting) which has "ceiling fan mode" which allows circulation even with the vent closed.
Might be using furnace heat tho over thanksgiving, since it'll be cool in Savannah

Btw, the low fan setting does indeed only apply to a/c blower (whether A/C is on or you have the fan always on, even when not cooling using A/C), and not the furnace fan

Thanks folks for the note. I guess the low fan speed would be alright for air movement and ventilation. I know the furnace has only one speed. I just wondered who used the low speed and why. The thermostat I have is a coleman
7330G3351. I wish I knew how to post a picture on here, I just don't know how. I have one on my tablet but can't get it on the post.
GOT IT............Never mind the "I can't"
Thanks again all,

Jim

I would recommend replacing the thermostat with the digital version like this

I just installed the same (except mine is in black)
Simple 6 wire attachment with wire nuts

The digital one has less hysteresis (less variation between when it switches off and back on again) than the analogue one, and also shows current temperature.
Quite a nice simple upgrade, and well worth it in my opinion

Thanks Leefl, I appreciate the information. I have been in the air conditioning business for over 40 years and have a couple of old digital thermostats kicking around and thought of using one but wasn't sure about the additional fan setting.eThe temperature swings you noted are driving me crazy when out in cold weather.

The one you recommend looks like an easier fit and will probably work better than my bubble gum and bailing wire approach.

Thanks again.
