outdoor air temperature Sensor installation
When outdoor air temperature is very low, condensation can occur on
windows and other surfaces which may cause damage to the structure. To
minimize this risk, the outdoor air temperature sensor should be installed.
The outdoor air temperature lowers the humidity setpoint to a safe level,
where the indoor relative humidity is too low to condense. The outdoor
temperature compensation control adjusts the maximum humidity setpoint
according to the values shown in Table 1. The humidistat will automatically
detect if the outdoor air temperature sensor is connected and control the
relative humidity setpoint accordingly.
