The Power Manager 346 is designed to allow non-tekmar products to interface with a tekmarNet
®
4 communicating heating system. It
can be used in applications that use 3rd party thermostats, zoning devices, or mechanical equipment that requires a hot water demand
from the boiler system. This product provides demand inputs for up to 4 different reset water temperatures (high temp, low temp , low
temp 2, low temp 3). It has the capability of switching 3 pump outputs and provides wiring for up to 3 tekmarNet
®
4 devices, as well as
the 4 separate demand inputs to create a heat call on one of up to 4 possible reset water temperatures.
