The RD200 series heating controls is an energy management system for small buildings with steam boilers. It can average up to 8 temperature sensor inputs, as well as handle up to 10 relay outputs, making it capable of controlling vacuum and circulating pumps, air dampers, and motorized valves.
The RD200 series provides different options for boiler control. The AH207 steam control uses wired remote sensors, which is handy for small apartment buildings that do not necessarily require wireless equipment. The RF207, on the other hand, makes it easy to install a heating control system in medium-sized to high-rise buildings without the difficulty of pulling sensor wires. Both controls are also designed to handle buildings with multi-zone systems.
The SF201 utilizes steam duty cycle control to determine the length of heating cycles. It is capable of calculating heat cycle length for ON and OFF periods, and performs true correction for the night setback and morning boost temperatures.
