Continuous or Intermittent Fan Operation

Note: Please read these instructions completely before attempting to operate the unit.

When unit is equipped with a continuous/intermittent fan feature, please note the following. The toggle switch is
located on the left hand side of the unit and is marked as such. This switch is used to switch between continuous and
intermittent fan operation.

With the toggle switch in the

position, as indicated by the label next to the switch, the indoor fan will

continue to operate as long as the unit is switched on in either the heating or cooling mode. The fan will operate
continuously at the fan speed selected.

With the toggle switch in the

position, and the unit in cooling mode, the indoor fan will operate only

when there is a call for cooling by the adjustable thermostat. Similarly with the unit in heating mode, the indoor fan will
operate only when there is a call for heating in order to satisfy the heat setting on the adjustable thermostat.

The effective indoor temperature sensing and highest comfort levels are achieved when the room air is being drawn
continuously across the sensing bulb of the thermostat.

The most effective indoor temperature sensing and highest comfort levels are achieved when room air is being drawn
continuously across the sensing bulb of the unit thermostat.

“Continuous”

“Intermittent”

If complaints of large temperature swings in the room

are experienced, then switch the unit to continuous fan operation.
