Control Description The Universal Reset Module 423 provides outdoor reset to a hydronic heating system in order to maximize comfort and efficiency. The 423 can operate two on / off boilers or two modulating boilers. The 423 can override the outdoor reset water temperature to provide Domestic Hot Water or Setpoint operations. The 423 can operate four outdoor reset water temperatures, up to three of these water temperatures can be mixing water temperatures. To operate a mixing device, a Mixing Expansion Module must be connected to the 423 for each mixing water temperature.
