4. OPTIONAL APPLIANCE MONITORING
The FAVC provides 4 optional monitors to optimize energy usage and ventilation effi ciency based on
activity of connected venting appliances. Refer to Figure 9 for optional appliance dial display and
Table 4 for Appliance dial ranges and factory settings.
FIGURE 9:
OPTIONAL FAN MONITORING SETTINGS
The appliance monitoring connection terminal block (See Figure 1, on page 4) is used for connecting up
to four (4) separate optional appliances (multiple bathroom exhaust fans, clothes dryer, range hood,
etc.) for monitoring or interacting with exhaust operations. Please note any appliance can be moni-
tored if its air fl ow is within the appliance dial setting range. When appliances are active, the length
of time in operation and fl ow rate of the device are used to credit against the ventilation requirements.
Dwell time for appliance #1 and 2 is 2 hours maximum. Dwell time for appliance #3 and 4 is 4
hours maximum.The appliance monitoring features are based on the following equipment devices:
Appliance #1 – HRV/ERV or Bathroom Fan or Exhaust Fan Appliance
Appliance #2 – Bathroom Fan
Appliance #3 – Clothes Dryer or Central Vacuum
Appliance #4 – Kitchen Range Hood or Draft Assisted Gas Log Fireplaces
The four optional terminal input pairs are intended for a 24VAC signal (must have a common feed). Each
input pair is electrically isolated from the other pairs. Unused input pairs should be left unconnected. The
associated control setting does not matter if the input is not used. The optional inputs are not
required for FAVC to operate properly. Refer to Table 5 for additional information regarding normal and
optional operational conditions for Appliances 1 through 4.
