Dip Switches
Two sets of dip switches are used to control
temperature limiting and auxiliary functions. The
dip switch controls are located behind the room
cabinet, through an opening in the control panel.
Factory settings will be in the DOWN position. (The
owner is responsible for checking switches and
ensuring they are in the desired position.)
Freeze Sentinel
When this switch is enabled (UP), it turns OFF the
freeze sentinel protection feature. With the switch
disabled (DOWN), the freeze sentinel is activated,
which automatically provides heat without user
interface. This helps to prevent plumbing damage
by turning the heater and indoor fan ON at 41°F and
OFF at 46°F.
Constant ON Fan
When this switch is enabled (UP), it allows the indoor
fan to run continuously, at high speed, even if the
unit is in the STOP position.
Occupancy Sensor
When this switch is enabled (UP), it allows the unit to
utilize an infrared motion sensor and a door switch
for occupancy detection. This feature allows an
energy management system to be installed and
operated in conjunction with the unit.
All Electric Heat (3800 Series Only)
When this switch is enabled (UP), heat pump
operation is locked out, causing the unit to provide
only electric resistance heat.
Cooling―Smart Fan
When this switch is enabled (up position), it
allows the indoor fan to cycle on and off with the
compressor. When this switch is disabled (DOWN), it
allows the indoor fan to run continuously.
Heating―Smart Fan
When this switch is enabled (UP), it allows the indoor
fan to run continuously. When this switch is disabled
(DOWN), it allows the indoor fan to cycle on and off
with the heat pump or heater operation.
Remote Thermostat―Class 2
When this switch is enabled (UP), it allows the
unit to operate with a class 2 remote control wall
thermostat. The unit controls are disabled.
Load Shedding (Central Desk Control)
This feature is active only if the unit is in CDC mode.
When this switch is enabled (UP), the indoor fan can
be turned ON or OFF with the unit controls.
