\What is Outdoor Reset? Outdoor reset is a feature of heating controls that optimizes the efficiency of steam and hot water boilers used for building heat based on the temperature outside the building. For hot water boilers, it will raise the boiler water temperature as the outside temperature drops, for steam boilers it will adjust the on-off cycling length of the boiler. Outdoor Reset Can Help Prevent Overheated Buildings Building codes require that the heating systems in residential and commercial buildings be sized to keep the interior warm at the location’s “Design Temperature.” Design Temperature is defined by ASHRAE as the minimum outdoor temperature that the location is statistically expected to experience for 99% of the year based on a 30-year average. This means that 1% of the time that the outdoor temperature is above the Design Temperature, the building heating system is oversized for the conditions. In a typical single-family home this is not an issue. On mild wint...

Big multi-use buildings like schools, churches and public buildings that have a tough combination of large spaces and small offices scattered throughout the building. Older buildings that may have had several renovations or additions over time.  Sometimes the building’s heating system was just poorly designed in the first place.

Building managers and owners want that too! An HVAC technician faced with an unbalanced, hard to heat building needs some powerful diagnostic tools to figure out what is wrong and how to fix it. Heat-Timer® wireless sensors can help diagnose those tough heating problems One of the primary tools are the wireless room sensors from Heat-Timer...
