Works only with HydroStats 3200-Plus and 3250-Plus.

  • Enables outdoor reset feature on HydroStat 3200-Plus and 3250-Plus models
  • Cuts off heating after a set outside temperature is reached
  • Reset Ratio - regulates boiler's temperature in accordance to the outside temperature with a 20 degree differential for burner operation
  • Thermal Boost - the control will continuously boost the reset temperature by 10 degrees every 30 minutes until thermostat is satisfied, reverting back to normal operation.
