On a system that uses a Heat pump, the heat setting utilizes the pump, and electrical coil heating as a backup.
On the EM setting the heat pump won't run, only the axillary coils will provide heat.
Which should be used heat or em heat
These two settings are found when you have a heat pump. Using the "Heat" mode uses the heat pump capabilities alone. Using em heat, turns on conventional electric coils to create more heat (and run up your electric bill)

Switches are usually made of Thermo Setting Polymers. Bakelite is an example.
there kind of the same really you should no the answer
The reset is a high limit safety device that cuts the voltage off when the temperature of the water tank becomes too high. If you feel that the water temperature is hotter that usual this is a good sign that the thermostat is not working. Check and make sure that the setting of the thermostat has not been altered. It should be set for around 140F. If the setting has not been adjusted then there is a good chance that the thermostat needs replacing
it may blow cold air due to the fact that the heat anticipator on your thermostat may be set to long. you can change useing your owners manual for your thermostat but you should have a service tech do it
