HP (W1) = pow = Heat
If the RTU that the economizer is installed in, is a heat pump, then this value shall
be set to one of the following:
(O) = Reversing valve powered for cooling.
(B) = Reversing valve powered for heating.
(W1) = Standard thermostat, reversing valve controlled by internal RTU defrost board.

Auto, Available, Not
Available
Allows for 2 speed indoor fan control circuit (IF) to be automatically detected when
wired. If circuit is not automatically detected, the functionality can be manually
enabled by choosing “available.” If there is a desire to disable functionality for
any reason, the operator can choose “not available” and the operation of the
economizer will function as if the device is not installed or confi gured.

Auto, 1, 2
Allows for up to 2 compressor circuits (CC1, CC2) to be automatically detected
when wired. If circuit is not automatically detected, the functionality can be
manually enabled by setting compressor Qty to 1 or 2.

Allows for exhaust fan control circuit (EF) to be automatically detected when
wired. If circuit is not automatically detected, the functionality can be manually
enabled by choosing “available.” If there is a desire to disable functionality for
any reason, the operator can choose “not available” and the operation of the
economizer will function as if the device is not installed or configured.

Allows for humidity sensors to be automatically detected when wired. If sensors
are not automatically detected, the functionality can be manually enabled by
choosing "installed".
If there is a desire to disable functionality for any reason, the operator can choose

Allows for the Outside Air Humidity Sensor to be automatically detected when
wired for enthalpy change over strategy. If the sensor is not automatically
detected, the humidity sensor can be manually enabled by choosing “installed.” If
there is a desire to disable functionality for any reason, the operator can choose
“not installed”, and the operation of the economizer will function as if the device is
not installed or configured.

Allows for the Return Air Humidity Sensor to be automatically detected when wired
for differential enthalpy change over strategy. If the sensor is not automatically
detected, the humidity sensor can be manually enabled by choosing “installed.” If
there is a desire to disable functionality for any reason, the operator can choose
“not installed,” and the operation of the economizer will function as if the device is
not installed or configured.
