Burnham RTC (Return Temperature Control) Folleto
for Commercial Boiler Applications
www.commercialcastiron.com
The Burnham Commercial RTC Return Temperature Control provides an economical and effective means of boiler
protection from thermal shock and sustained condensing operation. The RTC monitors the boiler return water
temperature and operates a 3-way diverting valve and boiler circulator to maintain a minimum return temperature
of 135°F or greater. An outdoor reset function is also available to reset the system water temperature based on
outdoor air temperature. Studies indicate that resetting the boiler and system water temperature increases effi-
ciency and reduces operating costs. The controls is available in two configurations: Basic RTC Kit and RTC kit with
Outdoor Reset Control.
