OPTIONAL OUTDOOR TEMPERATURE RESET FUNCTION

Order outdoor temperature sensor separately, Part #252-0263.
(1) Each humidistat and controller is equipped with an integrated reset function that
will limit the setpoint during cold weather operation. This will prevent condensation
on windows and building structures. Figure 10 illustrates how the setpoint reset
feature operates.
(2) This feature is enabled by removing the jumper from terminals 8 and 1 on the
humidistat and wiring the outdoor temperature sensor to these terminals.
(3) When the outdoor temperature setback feature is in effect, the humidistat will
normally display the calculated setpoint limit based on the outdoor air temperature.
A snowflake will also be displayed to indicate cold weather operation. When any
key on the controller is pressed, the LCD screen will display the customer specified
setpoint for a short duration.
