Heat Pump

That is normal. Secondary heat is not needed unless it is very cold outside. If the heat pump can't keep the house warm enough and the temps start to drop, the secondary heat kicks in. 2 degrees is normal.

Out door is not working

Check for communication from indoor to out door.Check power in out door unit. If not, check the following.
Keep cool mode and temp setting minimum 3 degree less than room temp.
Check indoor unit return air sensor. Disconnect sensor from PCB and measure resistance. 8 kOhm at 30C and 13 kOhm at 20C if not replace air sensor

Check Indoor Pipe Sensor Disconnect from PCB and measure resistance. Pipe sensor = 5kOhm at 25C. If not replace pipe sensor.
Thanks and hope helpful?

DT92E room stat appears to be very inacurate with its room tempreture, our normal room temp is about 22c we have to set the stat at 25c to get heat and the stat cuts out after a temp rise of 1c

All thermostat is calibrated @ difference of 2 cut in and cut off.
In heat mode, if you keep 25 and your room temp 23. it will start at the end of 24 or beginning of 25 degree.Cut off also @27 degree beginning. Please check Tips & how to do's in Fixya

HI I ahve a MSH-07NV airconditioner. It has had this problem before. I called a repair man and he said it was operator error. It turns on remotely then the fan stops and it goes down to 1 light that flicks...

As you don't mention the error code. There are 2 reasons for your unit as hereunder.
Check your indoor room temp sensor and coil sensor
Indoor unit return air sensor fault. Disconnect sensor from PCB and measure resistance. 8 kOhm at 30C and 13 kOhm at 20C if not replace sensor.
Indoor Pipe Sensor or Outdoor Sensor Assy fault, Open or Short. Disconnect from PCB and measure resistance. Air sensor = 10 kOhm at 25C, Pipe sensor = 5
kOhm at 25C. If not replace sensor.

Error C4 or CA

Turn off the heatpump. Start it again when temperature gets hotter than -20c.... Error C4 or CA (overheated compressor) often strikes after C2 error (and this error you often get when temp is belov -25c)
I had the same error myself, temperature was below -27. I turned the heatpump OFF. Turned it on again when temp was at -8c. No errors in display, and runs great! :-)

I have a westinghouse window unit and I think it has heat strips for the heat. How do I tell if it is a true heat pump or if it has heat strips and how do I get to the Heat strips in the unit to check.

If it is a heat pump, the compressor will be running both in cool mode and in normal heat mode.

Confirm the current indoor temperature. Turn the thermostat up one degree at a time until it comes on. This will typically be 1 to 4 degrees increase. As soon as it comes on stop increasing the temp.

If the compressor is running, it is a heat pump.

Check the temperature coming our of the vents at that time. You should have 30 to 60 degrees increase from the air temp going into the unit and the conditioned air temp coming out.

Then turn the T-stat up another 10 degrees. If the temp coming out of the vents increases by 20 degrees or more. the strips are on.

The strips operate in three situations.
1) the system is set to emergency heat
2) The heat pump cannot keep up with the demand for heat. (because its too cold outside, the desired temp setting is greater than 4 to 8 degrees above the room temp, or the HP is malfunctioning.)
3) The HP is in defrost mode

You could also take the panels off the unit and look for a reversing valve, but unless you know what you are looking for you will not recognise it.

No heating and no hot water, my boiler won't fire up

If there is a hi-limit switch, maybe it's open, reset the switch, and monitor the temperature, if the temp. increases over the set temp. replace stat, and clean lime off from the tank, if does not have a filtering system
