HOW THE OUTDOOR SENSOR WORKS

Outdoor Temperature Reset
The outdoor reset feature monitors outdoor temperature to continuously adjust the boiler

water to the minimum temperature required to satisfy the heat demand. The feature is

activated automatically when the Hydrolevel OS-100 or OS-200 is wired to the OR and C

spade connects on the HydroStat. When connected, Outdoor Reset overrides the Thermal

Targeting temperature reset method which is built into the HydroStat. The display will toggle

between boiler temperature (8 seconds) and outdoor temperature (2 seconds). If the sensor

becomes damaged or disconnected, the control will automatically revert back to the Thermal

Targeting reset method. The display will no longer toggle outdoor temperature.

Reset Ratio
The HydroStat control’s Outdoor Reset feature uses a reset ratio method to control

the boiler temperature. The reset ratio determines how much the boiler temperature is

adjusted for changes in outdoor temperature. A reset ratio of 2.0 means that for each 1

degree increase in outdoor temperature, the boiler temperature will decrease 2 degrees.

Conversely, for each 1 degree drop in outdoor temperature, the boiler temperature will

increase 2 degrees. The control adds 10 degrees to the calculated reset temperature

and provides a 20 degree differential for burner operation. So, if the control calculates a

reset temperature of 150°F, it will set a target temperature of 160°F. It will then allow the

burner to fire up to 160°F and draw down to 140°F before re-firing. This operation will

maintain the desired average temperature of 150°F. You can check the current target

temperature at any time, by pressing the Test/Settings button in 4 short intervals.

Thermal Boost
To insure that the heating system always satisfies a call for heat, the HydroStat control

is equipped with a thermal boost feature. If the thermostat is not satisfied thirty minutes

after the boiler reaches the reset temperature, the control will boost the reset temperature

by 10 degrees. It will continue to boost at 30 minute intervals until the call is satisfied.

Once the call is satisfied, the control reverts to normal operation, utilizing the calculated

reset temperature.
