Universal Reset Control - Two Mixing, Two Stage Boiler, DHW & Setpoint

Control Description: The Universal Reset Control 374 is a microprocessor-based control capable of providing a reset boiler supply temperature and two reset mixed supply temperatures based on outdoor air temperature. For mixing devices, the 374 can use either two variable speed injection pumps or two floating action mixing valves. The 374 is also capable of controlling an indirect Domestic Hot Water (DHW) tank and / or a setpoint load. The control is also capable of controlling up to two on / off boiler stages. Individual zone temperature control can be achieved by using a conventional thermostat system.
