UNIT INTRODUCTION
This 677B unit is a small packaged Hybrid Heatt system that can
utilize both the efficiency of heat pump heating and the comfort of
gas heating. The system will optimize for ideal heating, depending
on several factors. This unit uses Puron ® , the ozone friendly refrig-
erant, for cooling and heat pump heating.
You may notice your two--stage packaged Hybrid Heatt system
runs for longer periods of time. Nearly 80% of the time it’s
running, it is operating in low--stage, and your indoor temperature
will remain more consistent with fewer drafts, better humidity
control, enhanced comfort and enhanced energy efficiency.
FIRE, EXPLOSION HAZARD
Failure to follow this warning could result in death, personal
injury and/or property damage.
Do not attempt to light by hand.
WARNING
!
FIRE, EXPLISION, ELECTRICAL SHOCK HAZARD
Failure to follow this hazard warning could result in personal
injury, death and/or property damage.
1. Do not turn off the electrical power to unit without first
turning off the gas supply.
2. Before attempting to start the gas heating section,
familiarize yourself with all the procedures that must be
followed.
! WARNING
Starting or Shutting Off Unit
To start the unit:
1. Turn on the electrical power supply to unit.
2. Turn on the gas supply to unit.
3. Select temperature and set User Interface (UI) control to
desired mode.
To shut off unit:
Note: If the unit is being shut down because of a malfunction, call
your dealer as soon as possible.
1. Set UI control to OFF.
2. Turn off gas supply to unit.
3. Turn off electrical power supply to unit.
OPERATING YOUR UNIT
The operation of your unit is controlled by the Evolutiont UI. You
simply program the UI and it maintains the indoor temperature at the
level you select. See UI manual for detailed instructions.
To better protect your investment and to eliminate unnecessary ser-
vice calls, familiarize yourself with the following facts:
Step 1—Cooling Mode
With the SYSTEM control set to COOL, your unit will run in cool-
ing mode until the indoor temperature is lowered to the level you
have selected. On extremely hot days, your unit will run for longer
periods at a time and have shorter “off” periods than on moderate
days.
Step 2—Hybrid Heating Mode
Your Hybrid Heat system combines the strengths of two heating
sources; an electric heat pump and a gas furnace. A Hybrid Heat
system provides more control over your monthly energy bills by al-
lowing you to choose the most economical method of heating. As
conditions change, the system automatically switches between the
two sources to maintain greater efficiency than with a single--source
heating system.
