EDMMT712101
Control by 2 remote controllers
Purpose • Function
One unit (or one group) of Heat Reclaim Ventilator Unit
Perform fine operation of Heat Reclaim Ventilator Unit and display output, at hand or at a distance, by using two remote controllers.
All operating and display functions of the remote controller can be performed from either one of the remote controllers. (However,
field settings can be made only by using the main remote controller)
POINT
Wiring to the remote controllers is branched out from the main unit (as shown in the illustration).
(The wiring can be routed from the main remote controller to the sub remote controller. However, it takes a lot of work to put two
wires inside the remote controller.)
Different types of remote controller (BRC1H62, BRC1E63) cannot be mixed for use.

Purpose • Function
Controls multiple Heat Reclaim Ventilator Units (up to 16 units) simultaneously on a large floor.
All operations and individual setting functions of the remote controller can be collectively performed.
Even in the event where unusual display is shown, you can identify specifically which Heat Reclaim Ventilator Unit output the signal
by confirming the unit number.
(Control by 2 remote controllers can be performed if one more remote controller is connected.)
POINT
Address is automatically assigned and thus no address setting is required.
(Addresses are assigned arbitrarily. To check the address number, use the service mode setting "forced fan ON" and check the
operation status.)
At least one remote controller is always required.
