Universal Reset Module - Two tN4, Mixing, Boiler, DHW & Setpoint

Control Description The Universal Reset Module 422 provides outdoor reset to a hydronic heating system in order to maximize comfort and efficiency. The 422 can operate a single on / off boiler or a single modulating boiler. The 422 can override the outdoor reset water temperature to provide Domestic Hot Water or Setpoint operations. The 422 can operate two outdoor reset water temperatures, either one boiler water temperature and a single mix water temperature, or two mix water temperatures. To operate two mixing devices, a Mixing Expansion Module must be connected to the 422. The single mix output can operate a floating action mixing valve or a variable speed injection pump.
