Question about Mitsubishi Mr. Slim MXZ30TN Air Conditioner
I have purchased and installed two mitsubishi multi-split systems (MXZ-A series) for my home's heating/cooling.
To one of them, 3 roof units (SLZ-KA35VA) are attached.
While operating in heating mode, the roof units, will not operate: power is turned on, but the fan with hot air does not work. It seems to be in standby mode...
This happens, even though I set the desired temp. to be at 28 degrees, while room temp. is at about 20. It seems the thermostat 'thinks' the temp. is much higher...
Indeed, placing a thermometer at the gill of the unit, it read over 27 degrees (while room temp. was about 20 degrees).
What can I do about this?
My dealer cannot help -- simply suggested to set desired temp. as high as possible...(28 degrees is the highest, meanwhile...).
Is there any way that the thermostat can be 'fooled'/tricked.
What I do now, is switching the operating mode (from heating to auto, cool, and then back to heat). Then, somehow the fan starts blowing hot air out...
(I guess because cooler air blows when in cooling mode, and the air around the thermostat is cooled)...
Any other suggestions?
I would sincerely appreciate any help.
The thermostat would need to be insulated better from the air that is surrounding it. Im assuming that the thermostat is located on the wall unit where it blows out the air. This could mean that it is actually reading more from the outside temp, than whats inside the house. Another thing to consider is the location of the thermostat, even it being close to anything in the house that produces some kind of heat will effect the condition of the air. If anything, its the manufacturers mistake if it was properly installed in the first place and if defective, they should replace it. hope this helps.
