Hydrolevel OS-200 is a wireless outdoor sensor kit, designed to monitor outdoor temperature to adjust the boiler water temperature. It overrides the Thermal Targeting feature on HydroStats, and uses a reset ratio method to control the boiler temperature, determining how much the boiler temprature is adjusted for changes in outdoor temperature. Works only with HydroStats 3200-Plus and 3250-Plus.

While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
