Honeywell T775R2043 Temperature Controller W/2-Modulating Outputs & 2-Sensors

The Honeywell T775R2043 Temperature reset controller is used to manage the HVAC systems with better accuracy. This part uses two modulating outputs and two sensor inputs to regulate the supply water temperature of heating or cooling systems in response to changes in the outdoor temperature. By measuring both the outside and inside environment, the T775R2043 controls the boiler or chiller for efficient energy utilization. This results in better comfort for the occupants by eliminating over or under-heating, and lower energy bills due to the elimination of wasteful heating or cooling. They are normally applied in closed hydronic heating/cooling circuits that include boilers, chillers, and heat exchangers. Advantages are improved energy efficiency, better comfort, and easier control of the system.
