when running the heat-pump the air blowing from the heat ducts is not hot ( it's to cold for the heat-pump).
you have a main furnace and it won't turn on ( is thermostat selected for this source), ( is the power switch for main furnace on ), ( is fuse for this furnace good).
If these are good (check thermostat wiring at thermostat, and transformer).

When to use emergency heat setting on a heat pump?
Heat pumps don't work well when its below freezing point temperature's
What does the EM heat mean on your thermostat for your central AC heating unit?
If you have a heat pump A/C unit then you have auxillary heat and emergency heat. The EM stands for emergency heat, which is using only your electric heat strips or gas heat, depending on your system. The auxillary heat uses your compressor inside of your outside unit. Say the house is 60 degrees inside and you set your stat to 70, the temperature difference is so great that if the heat pump alone cannot satisfy, then the auxillary heat would come on to assist the heat pump. Say you were to get a leak in either your condenser or evaporator coils, your heat pump would not work on the regular heat setting on the tstat. In this circumstance you would want to use just the emergency heat until a service tech can evaluate the system.
Should you use emergency heat on temperature below zero?
Yes, emergency heat can be used in temperatures below zero. It is designed to provide a supplemental source of heat when the primary heat source is not working properly. However, it is important to note that emergency heat can be expensive to operate, so it should only be used as a temporary measure until the primary heat source is restored or repaired.

How do you fix a emergency brake on a 89 ford ranger?
The emergency brake system is a cable-actuated system that only controls the rear brakes of the vehicle. Adjustments are sometimes necessary as are correct linkage hook-up. To inspect if system is working at all you can remove rear brake drums and check. A model-year specific manual from an auto parts store covers all of this in better detail.
Should the thermostat be set to EM heat if the heat pump has Auxiliary heat?
Emergency Heat [EM] should only be used as a backup if the heat pump fails. EM heat uses 1.5 to 3 times as much or electricity as the heat pump.
92 merceds 400E the heat is NT working?
If the heat is not working on a 1992 Mercedes 400e, there could be a number of problems. The thermostat could be sticking if the car is only blowing cold air. If there is no air at all, the blower motor or the heater core could be at fault. There could also be a burned out fuse for the entire system.
Does it take more friction to stop a car using emergency brakes or regular brake?
In order to stop a car using ONLY the emergency brake, roughly 4 times the force would have to be applied to the emergency brake system that the normal brake system. This is because the emergency brake only activates one to two pads in the rear of the vehicle, where as the normal brake system activates ALL the pads on every wheel. Emergency brakes are NOT designed to stop a moving vehicle, they are designed to hold a stopped vehicle in place.
Should your outdoor HVAC compressor run when your heater is on?
no sounds like your wires are crossed at your thromsthat Answer If you have a heat pump system, YES the compressor should run. You can find out if the system is a heat pump usually by looking at the thermostat. Heat pump thermostats usually have "Cool-Off-Heat-Emergency Heat" on the system switch. Another way would be to feel the air coming out of the outside unit when the heat is on. If the air coming out feels very cold, then it's a heat pump. even if you have a heat pump, the only way the in door unit should be producing heat is if you are all electric if you are gas the heat pump should lockout to prevent the persure from getting to high causing the indoor coil to blow up.
