3200-Plus Hydrolevel Hydrostat Control Instruction Manual
Product Instruction
WARNING Electrical shock
hazard. To prevent electrical shock, death or equipment damage, disconnect
power supply before installing or servicing control. Only qualified personnel
may install or service this control in accordance with local codes and
ordinances. Read instructions completely before proceeding.
CAUTION To prevent serious
burns, boiler should be thoroughly cooled before installing or servicing
control.
WARNING Frozen pipes/water
damage. Central heating systems are prone to shut down as a result of power or
fuel outages, safety related fault conditions or equipment failure.
Installation of freeze protection monitoring or other precautions is
recommended for unattended dwellings in climates subject to sustained below-
freezing temperatures.
This document provides instructions for connecting the Hydrolevel Outdoor Sensor Kit to an installed HydroStat control. For information on installing the HydroStat control, please refer to the installation instructions provided with the control or log onto www.hydrolevel.com.
Before installation, determine the proper location for the sensor
- Sensor should be mounted on the northern outside wall of the house, shielded from direct sunlight.
- Sensor should be installed high enough off the ground to protect it from accidental damage or drifting snow.
- Sensor should be installed away from potential heat sources such as exhaust fans, windows, or doors.
INSTALLING THE SENSOR
STEP 1 Using the two screws and wire clip provided, attach the sensor
bracket to the side of the house
STEP 2 Secure the sensor on the bracket by pressing it down into the
slotted hole as shown above.
STEP 3 Using an extended wood or masonry bit, drill a ¼” hole through the
side of the house at a location giving the best access to the boiler and the
HydroStat control.
WARNING: Use caution to select the hole location away from wires or
piping within the house wall
STEP 4 Feed the sensor cable through the hole and into the house. Seal the hole with a bead of silicone or other appropriate caulking material
STEP 5 Inside the house, route the sensor cable to the HydroStat control. Splice in an additional length of wire, up to 500 feet, as needed. Use 18 awg wire for distances up to 250 feet or 16 awg wire for distances over 250 feet. Using a crimping tool, terminate wires with the two spade connectors provided.
NOTE: To avoid interference with the sensor signal, do not run the sensor cable close to any other wiring such as telephone, cable, power, etc.
WIRING
OUTDOOR RESET AND WARM WEATHER SHUTDOWN
Attach the spade connectors to the right and center spade posts (OR and C) for
full outdoor reset functionality including warm weather shutdown protection.
Wiring this way overrides the Thermal Targeting function of the HydroStat
control.
WARM WEATHER SHUTDOWN ONLY
Connect the wire ends to the left and center spade connectors (WWSD and C) to
add warm weather shutdown functionality only. When wired this way, the
HydroStat control will utilize its internal Thermal Targeting function to
reset the boiler temperature.
SETTING THE CONTROL
IMPORTANT: The outdoor sensor must be plugged in prior to setting the control.
SETTING WARM WEATHER SHUTDOWN
The warm weather shutdown feature prevents the boiler from providing space
heating when the outside temperature reaches a level that you select.
Available settings range from OFF or 40°- 70°F. The boiler will still operate
to satisfy a call for domestic hot water. The factory default setting for the
warm weather shutdown is 70°F.
To set the desired warm weather shutdown temperature:
Press and hold the TEST/SETTING BUTTON and simultaneously adjust the ECONOMY
dial to the desired setting. To turn the feature off – which will allow space
heating regardless of outdoor temperature – press and hold the TEST/SETTING
BUTTON and simultaneously turn the ECONOMY dial fully counter-clockwise.
Release the TEST/SETTING BUTTON. Be sure to reset the ECONOMY dial to the
correct setting. Any time the outdoor temp exceeds the WWSD setpoint, the
display will toggle boiler temperature (8 seconds), outdoor temperature (2
seconds), and OFF (2 seconds).
SETTING THE OUTDOOR RESET
The outdoor reset will regulate the boiler’s temperature based on the
temperature outside. On cold days, the boiler will run at higher temperatures
to meet the heating load in the house. On warmer days, the boiler will run
cooler to save energy while still meeting the heating needs of the house. The
HydroStat control uses a Reset Ratio to calculate and maintain the proper
boiler temperature.
To set the desired outdoor Reset Ratio :
-
Determine the Reset Ratio using the table below:
a. Locate the Outdoor Design Temperature for the system on the bottom of the Reset Ratio Chart below. Round down to the next lowest number.
b. Locate the Boiler Design Temperature (supply temperature needed to meet heating load at the Outdoor Design Temperature) on the left of the Reset Ratio Chart below. -
Adjust the ECONOMY dial on the HydroStat control to the Reset Ratio determined by the intersection of
a. and b. above.
Example: For a house located in Springfield MA (Design Temperature of 0°F) with baseboard heat (that was sized for the house based on the 180°F baseboard rating), the reset ratio is 1.50.

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 sensor 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.
