Auxiliary controls on your Zoneline.
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.
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.
