Inputs

Temperature Sensors

The M2000 Rooftop controller has four analog inputs that monitor outside air, supply air, return air and
mixed air temperatures (see Figure 10) and will integrate these readings into its control sequence. The
sensors used are standard 10k type thermistors that share a single common connection.
Alternatively, the supply air temperature can be retrieved from a zone controller that has its own supply
sensor and belongs to the M2000's network.
The outside air temperature can be also be provided by an alternate source. If a network controller is
present on the network, it can retrieve the outside temperature reading from one controller and distri-
bute it to any other controllers on the network.
