TEKMAR 346 - Control Description The Power Manager 346 has an internal transformer that powers a tekmarNet®4 (tN4) System Control 420, 421, 422, or 423. The 346 also includes four on-off demand inputs that can be used to provide a tN4 communication message to activate the reset module. This allows a mixture of non-communicating and tN4 communicating controls to use a tN4 System Control.
