INSTALL RECEIVER

STEP 1

When choosing the location for the receiver unit, consider the following:

• Interior wall.
• Keep dry. Avoid potential leakage onto the unit.
• Relative humidity less than 90%. Non-condensing environment.
• No exposure to extreme temperatures beyond 32° to 122°F (0° – 50°C).
• Away from equipment, appliances, or other sources of electrical interference.
• Easy access for wiring.
• Approximately 5 feet (1.5 m) off the finished floor.

• Grasp the front cover by the fingertip grips on the top and bottom of the enclosure and pull the front cover off.

• The enclosure is either mounted flush onto a wall or it can be placed onto a 2″ x 4″ non-conductive electrical box.
• The mounting holes in the enclosure accept #6 screws.
• Wiring to the control enters the wiring chamber through the back or bottom of the enclosure.

PROVIDE POWER

STEP 2

NOTICE: The receiver unit must be powered with 24 VAC.

Wiring to HydroStat Model 3200-Plus (Gas applications)

• The 3200-Plus provides a 24 volt power supply in the thermostat terminal block located at the top left hand corner of the control. Make connections as shown below.

Wiring to HydroStat-IC Model 4200

• The modeal 4200 is not equipped with a 24 VAC power supply. Locate an existing 24 volt power supply or add a transformer (supplied by others) as shown below.

Batteries in the Transmitter unit

• Remove the cover from the transmitter unit. Insert the included batteries as marked on the battery holder.
• 1.5V lithium batteries are required to provide the specified battery life and temperature range. Alkaline batteries have short life spans and may fail during cold weather.

Wiring to HydroStat Model 3250-Plus (Oil applications)

• The 3250-Plus is not equipped with a 24 VAC power supply. Locate an existing 24 volt power supply or add a transformer (supplied by others) as shown below.

STEP 3 – CONFIRM LINK

• If the communication light is displayed on the control, the transmitter is linked properly.
• If the light is not on, the devices will need to be linked.
• To link the transmitter and receiver, remove the cover on the transmitter so that the button below the battery terminals can be accessed.
• Press and hold both the button on the transmitter and the button on the receiver simultaneously for 5 seconds and release. Upon release, the linkup process will begin; the communication LED on the receiver will flash 8 times. Linking is successful when the communication LED is steady on.

The link button on the receiver can also be used as a reset. If pushed, the receiver will revert to a power-up condition; a temperature of 75°F (24°C) will be reported until the first transmission is received (up to 10 minutes).

STEP 4 – INSTALL TRANSMITTER

The transmitter should be mounted on a northern exterior wall away from direct sunlight. In order to prevent heat transmitted through the wall from affecting the sensor reading, it may be necessary to install an insulating barrier behind the enclosure.

• The OS-200 should not be exposed to heat sources such as ventilation or window openings.
• The OS-200 should be installed at an elevation above the ground that will prevent accidental damage or tampering.
• Do not install the transmitter on a conductive surface.
• The transmitter will send outdoor temperature data every 10 minutes.

STEP 5 – SENSOR TERMINAL WIRING

Connect 2-conductor wire between the HydroStat control and the sensor terminals (3 and 4) on the receiver. This connection is polarity sensitive. Wire the output Com terminal on the receiver to the C terminal on the HydroStat control. Wire the output Sen terminal on the receiver to the OR (or WWSD) terminal on the HydroStat control. At power-up the receiver will report a temperature of 75°F (24°C) until the first temperature transmission is received (up to 10 minutes). Wait up to 10 minutes to verify that the temperature at the control is accurate. If the temperature displayed at the control is unreasonably hot the wires may be reversed.

Outdoor Sensor Terminals

STEP 6 – SETTING THE HYDROSTAT CONTROL
IMPORTANT: The OS-200 must be plugged in to the HydroStat 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

1. Determine the Reset Ratio using the table below:
   • Locate the Outdoor Design Temperature for the system on the bottom of the Reset Ratio Chart below. Round down to the next lowest number.
   • 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.
2. 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.

RESET RATIO CHARTOUTDOOR

Refer to the HydroStat instructions for other control settings.

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.

LOSS OF COMMUNICATION / TROUBLESHOOTING
If the Communication LED is not on, try the following:

1. Confirm that the receiver is powered with 24 VAC by observing that the green Power LED is on.
2. Locate the transmitter. Remove the cover, and push the button located below the battery terminals. The LED will flash once to indicate transmission. Locate the receiver, and see if the Communication LED is on. If it does not come on, it may be one of three problems:
   • The transmitter may be out of range. Try moving the transmitter closer to the receiver. Push the transmission button inside the transmitter and confirm that the communication LED turns green.
   • The battery life of the transmitter batteries may have expired. This is likely the issue if the batteries have been in extended service. They can be replaced with 1.5V lithium batteries.
   • The link may have been interrupted. Try re-linking the devices, as described on page 4.
3. If the communication LED remains off for over 30 minutes, please call Tech Support at 203-776-0473.
