In order for this Hunter thermostat to control your system, the
system type must be specified by selector switches on the printed
circuit board inside the thermostat. There are also other selector
switches that allow you to customize the features to suit your needs.
NOTE: When changing these features after installation, move
the HEAT / COOL selector switch to OFF before removing
the thermostat from the wall.
System Selector Switches:
■ Heating system selector (HG – HE switch)
The factory position for this switch is in the “HG” position. Leave
it in this position if you have a gas furnace or an oil burner.
If you have an electric furnace, test to see whether the Heat
and Fan come on as expected.
If Fan operation is normal, leave the switch in the “HG” position.
If the Fan does not come on within a minute of the thermostat
calling for Heat, change the switch position to “HE.”
The system selector has no effect in the cooling mode.
NOTE: “HG” position is for gas and most other systems. “HE”
position is for certain electric systems having a fan relay.
■ Furnace or Heat Pump selector (NORMAL – O – B switch)
The factory position for this switch is in the NORMAL position.
Leave it in this position if you have ANY system that uses gas,
oil, electric, or hot water heating.
If you have a single-stage Heat Pump (no auxiliary or
emergency heat source), then slide the switch to the position
that matches your Reversing Valve type. If your heat pump
system has a “B” wire, slide the switch to “B” for your
reversing valve that activates in HEAT mode. If your heat pump
system has an “O” wire, slide the switch to “O” for your
reversing valve that activates in COOL mode.
