Has anyone figured out how to adjust the temperature for freeze and overheat, I know the the sensor sends an alarm to the panel when it reaches 40F for freeze and 100F for heat. is the anyway to adjust that? Attics here in Texas can reach up to 130F during summer and during winter 40F seems a little high.
The temperature settings of the RE219 are non-adjustable.
The RE219 should not be used in attic spaces as they can commonly exceed its operating temperature range in addition to the high temp alarm threshold.
The temperature thresholds on the RE219 are intended to detect HVAC failure in conditioned space.
