Lennox Rooftop Units with enthalpy sensors
Lennox Rooftop Units with enthalpy sensors
(OP)
Hello,
I'm work in building commissioning. There are some roof top units with an modulating outside air damper. I would like to verify that the damper is modulating properly, however there is no test option on the controller located in the unit. Does anyone have any recommendations? Thank you.

Set the DAT set point high (e.g., 85°F). Cool the OAT sensor with ice (or as you mention, by spray can) and the dampers should modulate toward full outdoor air.
