ECONOMIZER PARAMETER CODES AND
MODES OF OPERATION
RELAY OFF TEMPERATURE (OFF)
Select the temperature in which the 3-way valve de-
energizes and the unit returns to cooling mode. Once the
controller reaches the relay off temperature, the green LED
on the controller will turn off. It is recommended that this
temperature be set between 50-55°F.
RELAY ON TEMPERATURE (ON)
Select the temperature in which the 3-way valve energizes
and the unit enters into economizer mode. Once the
controller reaches the relay on temperature, the green LED
on the controller will turn on. It is recommended that this
temperature be set between 40-45°F.
ANTI-SHORT CYCLE DELAY (ASD)
Select the minimum time that the output relay remains off
(de-energized) before the next on-cycle can begin. Setting
an ASD interval overrides the output relay and prevents the
3-way valve from being energized during this time. When
the ASD value is greater than 0, the delay interval will begin
every time the controller turns on and every time that an
off-cycle begins. It is recommended that this be set to 3.
SENSOR FAILURE MODE (SF)
Describes the functionality of the control in the event of a
sensor failure. Value must be set to 0.
