ZN: Zone Temperature

This input is not used if the controller is operating in generic mode. Neither the MP501 nor a BAS
system can use this input if the MP501 is configured as generic.

Outputs for Generic Applications

The MP501 includes four (4) outputs.

Binary output 1
Binary output 2

Binary Output 1/Binary Output 2

Binary outputs 1 and 2 are 24 Vac TRIAC outputs that switch ac common. They can function in two
different ways:
•
•
Note: The MP501 controls only one actuator. You cannot have both a 0–10 Vdc actuator and a tri-
Binary Output 3
This binary output is a relay with a maximum current draw of 1 A. This relay energizes whenever
the control loop in the MP501 is enabled and de-energized when the control loop is disabled (refer
to the section,
control loop is disabled, the interlock relay is de-energized.

AO: Analog Output

The analog output on the MP501 is a 0–10 Vdc output with a maximum current draw of 10 mA from
the connected device.

Overriding Outputs

The MP501 includes a manual output test. Use this feature to manually control the outputs in a
defined sequence (refer to the section,

effective to use this type of actuator rather than a 0–10 Vdc actuator.

Alternatively, binary outputs 1 and 2 can be used to control the two separate binary outputs in
stages. The MP501 will first turn on stage 1 (binary output 1). Then, as the control loop senses
a larger demand, stage 2 (binary output 2) will be controlled on.
