if the fan switch is in the Run position and not the auto position you are getting cool are when the heat element is not on. this is kind of like a way to circulate the air. look for an auto setting it then should only come on when needed. Keep in mind it is normal for the fan to start blowing before the heating element is warmed up, this prevents it from over heating, or coming on when the fan is not working
your fan most likely is wired for low speed for heat which is common. this should be determined when furnace is set up properly. motors that aren't modulating motors and are multispeed motors typically have low medium and high taps that come off the motor and go to the corresponding relay on the board. low and medium speeds are used for heat and high and medium speeds are used for cooling. but only one speed for heat and one speed for cooling many times medium never gets used. im not familiar with klimaire is this a mini split system and not a regular air handler. cause speed control should be adjustable from the remote. if its a split but if not reaching desired speed due to a malfunction in the units could cause it to run low speed just to maintain the temperature exiting the indoor unit.
I f it is fan that has more then one speed if you run it all the time,it may
not be on high sample : low fan speed runs all the time
med fan speed for heat
high fan speed is usually for air conditioning so if everything is good then it maybe the relay.
Hi Laurelrobin, When the unit is on "low fan", it is fan only, and is recirculating room air. If the damper is open, it can also bring in outside air. If the space is not occupied for extended periods, it's OK to turn the unit "OFF", as long as you have a newer unit with Heat Sentinel, and the Heat Sentinel is turned on. Heat Sentinel will not let the room temp get above 85F, as long as the unit is OFF. Also, in most cases it's best to keep the damper closed. You can check your owner's manual for more info on the Heat Sentinel and other auxiliary functions. I also have an article on the temperature limiting functions of the GE Zoneline.
