FIGURE 9: WIRING TO MODEL 8120X

MODEL 8145NC – TEST MODE
After all ducting and wiring is complete, plug in the ventilator, restore power to the HVAC system and make sure the switch controlling the outlet into which the ventilator is plugged (if applicable) is turned on.

1. Use the installed control to complete a circuit between the VENT terminals on the 8145NC.
2. Verify that the ventilator blower starts and that the integral damper opens.
3. If the ventilation controller has been wired to turn on the HVAC blower with ventilation, verify that the blower is on.
4. Measure the airflow (CFM) that the installed ventilator is delivering. See MEASURE DELIVERED AIRFLOW section on page 9.
5. Using the instructions provided with the installed control, adjust the ventilation settings as required.

MODEL 8145NC – SEQUENCE OF OPERATION
Refer to the installation manual provided with the control that is wired to the Model 8145NC.

MODEL 8145 – WIRING THE CONTROL TO THE HVAC SYSTEM

NOTICE

MODEL 8145 – CONNECTING THE CONTROL TO THE VENTILATOR
Plug the Control Connector into the back of the control at the location shown in FIGURE 13. Route the connector wire through the channels in the control and reattach the control to the mounting plate. Restore power to the HVAC system and plug in the ventilator when complete.
FIGURE 13: PLUG THE CONTROL INTO THE VENTILATOR

MODEL 8145 – OPERATION

The display will appear faint normally; the first press of any button will turn on the display at full power.

MODEL 8145 – TEST MODE
After wiring and set up have been completed, Test Mode can be used to verify that all components in the ventilation system function and that wiring to the HVAC system fan is correct.

MEASURE DELIVERED AIRFLOW

1. Make sure the ventilator is plugged in and wired to an external control (Model 8145NC) or that the integral control is wired to the HVAC system (Model 8145).
2. Use 1/4″ flexible tubing to attach a pressure gauge set to ” w.c. (sometimes shown as “in. w.g.” or “in. H2O”) to the inlet and outlet pressure ports on the ventilator. The pressure gauge should have as small a range as possible to get a meaningful measurement – a range of 1.0″ w.c. should be sufficient. Connect the high or “+” port of the gauge to the outlet pressure port on the ventilator, and the low or “-“ port of the gauge to the inlet pressure port on the ventilator. See FIGURE 14.
3. Model 8145NC – Turn on the ventilator using the installed control for the Model 8145NC. This can be done by temporarily changing the ventilation setting to 60 minutes/hour or you can simply place a jumper between the VENT terminals of the ventilator. Model 8145 – Turn on the ventilator by using the “Up” button to increase the ventilation setting to 60 MIN./HR.
4. Use the label on the cover of the ventilator, or TABLE 3, to convert the pressure reading to delivered airflow. If the pressure reading falls between listed values, either use the lower value or interpolate between values: CFM = Lower Value + [(Higher Value – Lower Value) 10 (Pressure Reading – Lower Value Pressure)]. The following is an example:
   • Measured Pressure Reading is 0.34 “WC.
   • TABLE 3 lists 200 CFM @ 0.3 “WC. and 170 @ 0.4 “WC.
   • Either use 170 CFM or interpolate:
   • CFM = 200 – [(200-170) 10 (0.34-0.3)] = 200 – [(30) 10 (0.04)] = 200 – 12 = 188 CFM
     Interpolating will demonstrate higher delivered airflow, but requires acalculation to be done.

MODEL 8145 – SET UP

NOTICE
Before setting up the control for use, the amount of ventilation air being delivered (CFM) by the installed ventilation system must be measured.

Throughout the Set Up Menu, the buttons are used to change values, the Select button is used enter the value and move on to the next Set Up Menu item.

MODEL 8145 – RATER/INSPECTOR VERIFICATION

To verify the ventilation time setting, press the Select button to scroll through the calculated Required Continuous CFM and the Measured CFM for this installation. If any value does not match the expected value, the Set Up Menu must be entered to change the floor area, number of bedrooms or measured CFM.

The calculation used for the ventilation time setting is (all calculations compliant with ASHRAE Standard 62.2):

• Measured CFM is entered during set up and Required Continuous CFM is calculated according to the equation below:
• Required Continuous CFM = ((Floor Area ft2 .01) + (No. of Bedrooms + 1) 7.5)

MODEL 8145 – SEQUENCE OF OPERATION

“CODE” SETTING
The control will turn on ventilation with a heating, cooling or fan call for the set number of minutes during a one-hour cycle period.

• IF outdoor temperature is above the high temperature limit, ventilation will not occur with a call for cooling or fan call.
• IF outdoor temperature is below the low temperature limit, ventilation will occur with a heat call.
• IF outdoor air temperature is between the high and low temperature limits and the HVAC equipment does not turn enough to meet
  • The control will also turn on the HVAC blower if wired to do so.
• If the outdoor temperature exceeds the limits set at the end of the first hour, then no additional ventilation will occur for another 60 minutes, and the cycle period will automatically adjust to four hours.
• When the ventilator starts again, it will sample the air temperature and if in range, will meet the set amount of ventilation during the four-hour cycle period.
  • For example, if Vent Time was set to 25 minutes per hour and the temperature fell below the low limit, ventilation would only occur during a heating call.
  • If the heating only operated for 10 minutes during the hour, the control will automatically change the cycle period to four hours and work to provide the additional 90 total minutes of ventilation (25 min/hr * 4 hours = 100 minutes, minus the 10 minutes of ventilation that occurred during heating) during the four-hour cycle period.
• IF the air temperature is still out of range, the control will automatically switch to an 8-hour cycle period, then a 12-hour cycle period and finally a 24-hour cycle period. During 8, 12 and 24 hour cycle periods, the total ventilation time increases to compensate for ventilation effectiveness as defined in ASHRAE Standard 62.2. When the cycle period automatically adjusts to 24-hours, the control will turn on ventilation to meet the requirements even if the temperature is outside of the set limits.

“ COMFORT” SETTING

• The control will turn on ventilation with a heating, cooling or fan call by the HVAC equipment, if the outdoor air temperature is within the high and low ventilation temperature limits and the indoor RH is within the high and low RH limits, for the set number of minutes during a one-hour cycle period. If the HVAC equipment does not turn on enough to meet the ventilation time within the hour, the control will turn on ventilation without a call, if the outdoor air temperature and indoor RH is within the set limits. The control will also turn on the HVAC system blower, if wired and set up to do so. If the outdoor temperature or indoor RH are outside of the set limits, then no ventilation will occur.

FILTER CLEANING

• Normally, the fresh air filter will need to be removed and cleaned every six months, but check it after the first three months following installation to determine if more or less frequent cleaning will be necessary. After cleaning the filter inside the ventilator, clean off the screen at the fresh air intake hood on the outside of the house. The most common cause of reduced ventilation is a clogged air intake hood.
• To clean the ventilator filter (see FIGURE 15):
  1. Flex the outside edges of the filter door to disengage it from the housing.
  2. Lift the filter door and remove the filter from the ventilator.
  3. Use water to rinse the filter and shake the excess moisture off the filter.
  4. Replace the filter in the ventilator and press the outside  edges of the filter door to snap it in place.
