Question No User Manual for Heat Pump...Most Efficient Way to Operate???

My wife and I just recently moved into a 15-year old Condo in SouthEastern Massachusetts. We have a heat-pump heating system. The heat-pump system is just as old as the condo. The previous owner did not save the user manual for the pump and the thermostat. In cold temperatures, say below 30 degrees, what is the most efficient way to run a heat pump? We have a York heat-pump system...should we run it in the "EM. Heat" or the normal "Heat" mode? Sometimes, when we run it in the normal "Heat" mode, the red light ("EM. Heat") at the top of the thermostat begins to blink...and remains blinking unless we shut it off. Does this mean the system requires maintenance or something is wrong with it? Or, does it mean that the system switched operating modes? Please to heat pumps.

Best to leave it on the regular heat pump. You get more heat for your money than the emgerncy heat. Not sure what you have to t-stat, It more likely will be 2-stage. If the heat pump can't keep up (temp drops), the 2nd stage (your strip heater) will turn on to help recover.

The flashing light just tells you it's on emg heat. Nothing to worry about.

Don't use set back on a heat pump, set it and forget it.

The air blowing will be cooler than gas/oil heat.

The system will run more than gas/oil heat.

What's the make/model# is your system.. We maybe can find ou the owner's manual on the net.

Thanks Jay...unfortunately, the unit is so old, that most of the numbers are illegible.

The only numbers I can make out are on the inside of the unit. They're on three seperate lines, but no designation:


It's a YORK system...thanks for your help.

On York systems that are 10-15 yrs old use a "Yorkguard" system that when installed right and there is a problem the thermostat sends out a signal. Count the flashes. They blink fast then pause and re flash the signal. Count the flashes and call a york dealer to repair, let him know how many flashes it blinks. This will let him know what parts to bring to slove the problem.
