I went to the web site (http://www.rinnai.us/documentation/downloads/Owners_Manual_1004.pdf)
for this and on pg 25 is a description of the economy mode and its use----I'm not trying to get smart here but are you following the instructions as per mfg---here's is some thoughts----from what I can see via diagram pg 12----it show a thermistor low on the side by the combustion motor----from the schematics & diagram I'm surmising that the thermistor is the sensor for temp control----from past experience----have sensor that close to the floor usually dictates that if the floor is abnormally cold (in that area) versus the room temp----the therm will not be satisfied because heat generated rises drawing cold with it----around the therm---this is a convection issue----cold wall cold floor etc----being this is a space heater which will heat the room air not necessary the floors or walls due to it's design----these are some of the issues you could be having----by the description of the issue this heater is in a particularly cold room----your floor--sill and/or wall may need/should be insulated better to stop the cold convection while this is operating----this is the best I came come up with at the moment-----good luck

According to the owners manual, the "Economy" mode is designed to reduce the temperature setting by 2 degrees every hour. May not be what you were expecting... On the too hot issue: Check the thermostat setting - it can read either Celsius or Farenheit - Make sure you are setting it to what you think you are... Recommendation: if it is heating higher than set temperature is 1) set the temp lower and see how it does or 2) call a repair man to check and calibrate the thermostat.

How do you adjust the temperature on this model

Adjusting the temperature on your oven model is a straightforward process. First, turn the oven on and press the "Temperature" button until you reach the desired setting. If you have a manual dial, turn the knob until it reaches the desired temperature. Once this is done, the oven will heat up to the desired temperature and will beep when it's done. As an added safety measure, it's important to ensure that the oven is not set to an excessively high temperature as this could cause a fire. Additionally, be sure to open the oven door occasionally to allow some of the heat to escape, which will help to keep the temperature consistent. Finally, for optimal results, it's important to regularly check the temperature with an oven thermometer to ensure accuracy.

Why does my lasko 5842 model keep kicking off and I keep the filter clean

answer is in instructions
Save-Smart®
Press () to activate the Save-Smart®Function.
1.Set the thermostat to desired temperature using the +/-
buttons (Note: The default Save-Smart®temperature is 72 ? F)
2.When you reach the temperature at which you want to
set the unit, the set temperature will flash several times
and then the display will return to indicate the current
room temperature and will gradually change as the
room temperature changes.
3.When the air temperature is less than the set temperature,
the heater will run in HIGH heat.
4.Once the thermostat reaches the set temperature the heater
will automatically switch to LOW heat to save energy.
5.When the air temperature reaches 4? above the set temperature,
the heater will turn off. The Heater will cycle off and on in the LOW

All this happens automatically with Lasko Save-Smart®Technology.
To deactivate the Save-Smart®function, press Save-Smart®

My spa is at 89 and its set for 104 and the pump will not cut on what is the problem

You may be in economy mode. Economy only heats the water during a programmed filter cycle. You want it to be in standard mode which turns on the hot tub once the water is 2 degrees below the desired temperature. There should be a mode or program button on your topside. One some systems you'll have to hit prog/mode button then the temp up button to change the mode. There is also a sleep mode. Never used it not sure what it's for.

How do I turn my thermostat down?

I think you may be misinterpreting what it's telling you. The up down buttons select the DESIRED temperature, when it goes back to the same number it's showing you the actual temperature, which given time should eventually reach the desired temperature.

Hi: Last week, a contractor installed the above-mentioned new 16 seer heat pump, an air handler and a heat kit. Our house has 3 levels, each about 800 square fit. Initially the house would not heat above...

That is worrysome about putting refrigerant in hap hazzardly... There is a math style process involving pressures and temperatures in two locations that dictate how much ref. goes in. Anything else shows clueless installer. Too much or too little ref. will not work correctly.

Heat pumps do not work below about 33 degrees outside temp. Above that them, aux heat should not be coming on...

You would need to verify that the system you have is rated for the space that you are trying to heat...

Heat pumps heat more slowly than gas or electric, so using set back thermostat is not recommended. True economy comes from maintaining constant temprature. System has to work to hard to raise the temprature, and eats up savings in efficiency by allowing temp set back.

My Samsung Refrigerator can not keep the set temperature.

Normally your fridge is set +2 degrees C. with a differential of 3 so when it reaches +5 it should switch back on. if this is not doing this then a new thermostat may be in order.
