How do adjust temp scale to reflect temp setting accurately?

follow directions, plug it in adjust thermostat to desired temp. if room is warmer than thermostat setting the unit will not come on, raise setting to about 5 degrees warmer than room. Don;t know room temp set thermostat so that it reads 80 degrees.

Setting? Most fridge/freezers have a crude system of setting the temp. and this seems to be dependent upon ambient. For a few pennies they could set the temp. accurately. However, but most peeps just turn it up/down until it's "about right"
The temp. for your freezer will depend upon the length of time that you wish to keep things. Check out freezer stars online. However they tend to have pre-set temp.
For the fridge, this will depend upon what you want to keep in it. but usually 4C is pretty good. You need to get a thermometer, put it in a glass of water (this irons out fluctuations). And check it after an hour. Adjust a little and check again. Repeat until happy.
Note that a cold room can prevent a fridge operating, so be aware of this.

The old white-rogers thermostats with a mercury switch are adjustable. snap the face off. In the center you will find a plastic slot screw. set the indicator to the actual room temp.
Other type ? Replace the thermostat

are you sure thats not the setting thats showing not the room Rh

most homes are 70% Rh as normal !


external Rh meters can be purchased if you suspect that one on unit is not accurate for not a lot of money now

Great question! It sounds to me like the Skytech's swing temp setting may be out of whack.
Here is a quick link to the product page with a link to the owner's manual at the bottom if you need: Skytech 3301 Fireplace Remote.
Below is an excerpt on how to check and modify the swing temp settings for the Skytech 3301. (I apologize if the copy/paste formats poorly).
The Thermo Mode on the transmitter operates the appliance whenever the ROOM TEMPERATURE varies a
certain number of degrees from the SET TEMPERATURE. This variation is called the "SWING" or
TEMPERATURE DIFFERENTIAL. The normal operating cycle of an appliance may be 2-4 times per hour depending on how well the room or
home is insulated from the cold or drafts. A smaller "swing number" increases the number of cycles so the room temperature is more
constant. A larger "swing number" decreases the number of cycles, which saves energy, in most cases. The factory setting for the "swing
number" is 2. This represents a temperature variation of +/- 2
0
F (1
0
C) between SET temperature and ROOM temperature, which determines
when the fireplace will be activated. The "SWING" number values are:
1=+ 1
0
F (.5
0
C), 2= + 2
0
F (1
0
C) and 3 = + 3
0
F (1.6
0
C).
SETTING THE TEMPERATURE SWING (TEMPERATURE DIFFERENTIAL)
1. To change the temperature "SWING" setting (1-3), press the TIMER/TIME and DOWN buttons
simultaneously to display the current "SWING" setting in the SET TEMP frame. The letter "S" will
display in the ROOM TEMP frame on the LCD screen.
2. Press the UP or DOWN button to change the temperature differential or "SWING" (1-3). See above
for 1-3 "SWING" temperature valves.
3. To store the "swing number press the SET button or allow 15 seconds to lapse, and the new "swing
number' will be automatically programmed.

MANUAL CHECK OF " SWING" OR TEMPERATURE DIFFERENTIAL
The operation of the factory set "THERMO SWING" can be checked by adjusting the SET TEMP 2
0
F above or below the room temperature.
This will cause the system to turn ON or OFF. Normally the system will only respond to temperature changes every two minutes. Manually
changing the SET temperature will activate the system in less than 10 seconds. IF the "SWING" is changed, then a new room temperature
differential will respond. Factory setting of "SWING" temperature is 2
0
F.

It could be the scale is not accurate and you may need a new scale

I have a related concern. I put the Mr. Slim unit in my garage/workshop and most of the time need it just to keep the pipes from freezing. I'd like to set it at 45 or 50 degrees, but the lowest it allows is 59. I bought this to save energy, but it's forcing me to keep the room warmer that I'd like.

Depends on your Tstat. The set point is different from room temp. My tsat show set point and room temp. But to answer you when you set at 72 and room temp is 75 . It will go back to room temp till you reach that temp. Rusty

You can adjust the position of the room air sensor found on the back of the unit between the heater and the wall. It is a black rubber bulb with yellow wires. There is a few inches of extra wire you can extend higher to get a more accurate reading of room air. While you are back there, check for drafts that will give you false readings.

bad thermostat. the stat can be as must as 5 degrees off. try, if possible testing the unit in a differeent location
