Can one AirSense be used with two CommBoxes?

Each CommBox or Resibox will need its own sensor to trigger. Actually, each ‘box’ can take up to 4 sensors as each built-in relay contactor can be activated separately. However, the reverse is less simple. You cannot connect one sensor to two boxes and activate them simultaneously without a custom set-up where the dry contacts from the sensor are bridge to the second enclosure. Warmup does not support this installation and recommends the use of at least one sensor per ‘box’. Please follow the instruction manual for installation.
