OS-100 Outdoor Sensor Kit for HydroStat 3200-Plus and 3250-Plus

Description

Hydrolevel OS-100 is a wired outdoor sensor kit, designed to monitor outdoor temperature to adjust the boiler water temperature. It overrides the Thermal Targeting feature on HydroStats, and uses a reset ratio method to control the boiler temperature, determining how much the boiler temprature is adjusted for changes in outdoor temperature. Works only with HydroStats 3200-Plus and 3250-Plus.

Features:

• 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.
