Why does the split unit blow hot air in air conditioner mode, when switched on with the remote control.


because you have the temperature set at 28 degrees celcuis . Change the temperature to 18 degrees and it will cool 28 is hotter
It is a reverse cycle air conditioner it will warm the room if you set temperature to 28 degrees . Set it lower and it will blow out cold air.
Have exact same air conditioner as I recognise the remote control.
point it at the air conditioner when altering the temperature setting.
Check under the slide compartment also on the remote for more advanced settings.

Panasonic a c automatically stops cooling after every 10 min but indoor fan not stops and it will start again after 2 min . What is the problem?


the indoor thermostat setting is set to close to atmospheric temperature resulting in a cycle of the machine
for example if the room temperature is at 26 degrees c and you run the machine at 25 degrees c it will cycle
if altering the setting will not make a difference then have a technician check it out as it may be a faulty thermostat on the inside unit or an overload of the compressor

If i am away for any length of time, do i put the temp on vacation? does the water still get warm?


Since you didn't provide the brand & model of the thermostat, only generic help can be provided.

Most furnaces that run on oil or gas, make hot water all the time, 24 / 7 - winter, summer and everything between so to speak. They are controlled by an aquastat that may be set for any value between 140 - 180 degrees F. This is called "hot start" - simply because when the thermostat is set to a temperature higher than the room (turning heat ON), the water is already hot in the furnace, and is circulated immediately. If it was a "cold start", you'd have to wait for the water in the furnace to heat up from room temperature. This would substantially increase the amount of time it would take to heat the room.

Generally, the "vacation mode" simply halts the program from running. If your thermostat changes temperatures several times during the day / night, it will simply hold the lowest temperature - or a predetermined temperature built in - or chosen by you. You'll need to consult your manual to determine just how your thermostat handles the vacation mode setting. Post again if you can't find the manual - but tell us what brand and model it is.

I hop ethis helps - good luck!

Many heating thermostats don't allow for setting a temperature below 45 degrees F so freeze ups shouldn't be a problem.

Compressorruns fora short time


the thermostat controlling your unit likely has a window type of programming for digital or mechanical adjustment for older style thermostat that sets a minimum off temp and a maximum on temp, there may be an adjustment to set the range it operates at, otherwise you may have a defective thermostat controller unit and it needs replacing also insure that the temperature sensing element is clean and free of dust build-up and your filter is clean

Temperature varies 13 degrees around setpoint on aux heat


I don't have the book for this particular unit but, check the sequencers that control the electric heat mode, as the regulator heat pump works good. The part may have a time or temperature delay that is too long for you. Also if it has a remote thermostat, check the heat anticipate setting. You will have to check the installation manuel, but its usually .6 to .8, but I don't think that is the problem.
