the factory settings menu.
Hi Enthalpy: (Shown when Economizer is set to Fixed Enthalpy mode).
Setpoint for the highest outside air enthalpy can be to close the damper.
The range of adjustment is 26 – 30.0 BTU with a default value of 28.0.
Enthalpy DB: (Shown when Economizer is set to an Enthalpy mode).
Fixed Enthalpy mode: This is the amount that the outside air enthalpy must
drop below the Hi Enthalpy setpoint before the damper can reopen.
Fixed Enthalpy mode: This is the amount that the outside air enthalpy must
drop below the inside air enthalpy before the damper can reopen.
The range of adjustment is 0.2 to 1.0 BTU with a default value of 0.5 BTU.
Min OA Temp SP: This is the lowest temperature that the outside air can
be before the damper is closed. The range of adjustment is 20.0 to 45.0°F,
with a default value of 32°F.
Max OA Temp SP: (Shown only in Fixed dry bulb mode) This setpoint is
based on the climate zone setting and is not user adjustable. It is the
highest temperature that the outside air can be before the damper is closed.
Range of adjustment is 65.0 to 85.0°F.
OA DB: This is how much the outside air temperature must rise above or
drop below the OA Temp SP before the damper may reopen. The range of
adjustment is 1.0 to 5.0° with a default value of 1.0°.
