ELECTRICAL SHOCK HAZARD!
Turn OFF electric power to unit before perform ing
any maintenance or rem oving panels or doors.
FAILURE TO DO SO COULD RESULT IN BODILY INJURY OR DEATH.
Heat Pump Operation
Your new heat pump has several characteristics that you should be aware of:
!Heat pum ps satisfy heating dem and by delivering large am ounts of warm air into the living space. This is quite different from
!Do Not be alarm ed if you notice frost on the outdoor coil in the winter months. Frost develops on the outdoor coil during the heating cycle when tem peratures are below 45/F. An electronic control activates a defrost cycle lasting 5 to 15 minutes at preset intervals to clear the outdoor coil of the frost.
!During the defrost cycle, you m ay notice steam rising from the outdoor unit. This is a norm al occurrence. The therm ostat may engage auxiliary heat during the defrost cycle to satisfy a heating dem and; however., the unit will run to norm al operation at the conclusion of the defrost cycle.
In case of extended power outage...
If the outdoor tem perature is below 50/F and power to your outdoor unit has been interrupted for 6 hours or longer, observe the following when restoring power to your heat pump system .
!Set the room therm ostat selector to the "Em ergency Heat" setting to obtain tem porary heat for a m inim um of 6 hours. This will allow system refrigerant pressures and tem peratures enough tim e to return to a stabilized condition.
!In Em ergency Heat m ode, all heating dem and is satisfied by auxiliary heat; heat pum p operation is locked out. After a 6 hour "warm

Thermostat Operation
The
inform ation below is typical for most therm ostats. Ask your dealer for specific inform ation regarding the model of therm ostat installed.
Temperature Setting Levers
Most heat pum p thermostats have 2 tem perature selector levers: one for heating and one for cooling. Set the levers or dials to the desired tem perature set points for both heating and cooling. Avoid frequent tem perature adjustm ent; turning the unit off and back on before pressures equalize puts stress on the unit com pressor.
On heat pum p system s, increasing your therm ostat setting by m ore than 2 degrees may cause supplem ental heaters to turn on, reducing potential energy savings.
Fan Switch
In AUTO or INT (interm ittent ) mode, the blower operates only when the therm ostat calls for heating or cooling. This m ode is generally preferred when humidity control is a priority. The ON or CONT mode provides continuous indoor blower operation, regardless of whether the com pressor or auxiliary heat are operating. This mode is required when constant air circulation or filtering is desired.
System Switch
Set the system switch for heating, cooling or auto operation. The auto m ode allows the heat pum p to autom atically switch from heating mode to cooling m ode to m aintain predeterm ined com fort settings. Many heat pump therm ostats are also equipped with an em ergency heat m ode which locks out heat pump operation and provides tem porary heat supplied by the auxiliary heat.
Indicating Light
Most heat pump therm ostats have an amber light which indicates when the heat pum p is operating in the em ergency heat mode.
Temperature Indicator
The tem perature indicator displays the actual room tem perature.
Fan Control
For fan control your therm ostat may have a Fan Selection Switch that allows you to run the fan continuously or cycle it autom atically with the heating or cooling system . Switch the lever to ON for continuous operation and to AUTO for autom atic cycling.
For maxim um com fort satisfaction and continual air cleaning/filtering, constant fan operation is recomm ended.
