This summer we came out with the newest version of our WHF control board. The new control board has several new features which improve on the previous versions. It is now being phased into all AirScape models in production. The following are some of the improvements/changes made to the control board:
One of the biggest changes is how the actuator is controlled. The actuator(s) will now cycle the damper doors open before the fans turn on. We have also added LED indicators which indicate operation of actuator(s) and fan speeds. Programming your optional remote has become even easier with the new control board. Now all you have to do to mate your remote transmitter to the WHF is to turn the main power to the unit on and off by unplugging and plugging in the damper box power cord or turning the circuit breaker off and on at the electrical panel. We also added the ability to reset the remote programming as well.
Now, for all of the contractors or advanced users out there we added something for you too. The control board now has a master override or interlock. This is a safety switch that when enabled will turn off the fan(s) and close the damper doors. The interlock is now required by some community building codes to disable the whole house fan if for example a furnace turns on or a fire alarm is triggered. Please see future tech support blogs or give us a call for more information on the interlock.
