MicroNet LONMARK® 200 Series Controllers

The I/A Series MicroNet LONMARK 200 Series

Controllers MN 200 is an interoperable, LONMARK-certified

controllers. Controllers are loaded with a pre-engineered application,

that provides control for Magic Aire unit ventilators.

Controllers feature Sensor Link (S-Link) support, LED indication,

screw terminal blocks and are panel mounted in the left end

compartment. These controllers can function in either standalone

mode or as part of a LONWORKS® FTT-10 Free Topology

communications network that must be field provided.

Applications

Designed for new or existing system installations,

the MN controller provides control for:

• Unit Ventilators

Connectivity

Controllers offer the advantages of standalone and

networked control. Using an I/A Series MicroNet

Sensor (MN-SX series), the operator can monitor

controller performance and edit operational values.

The WorkPlace Tech Tool software is used to

program the controllers.

Features —

• Field programmable using WorkPlace Tech Tool.

• Uses LONMARK HVAC profiles for

interoperability.

• Capability to function in standalone mode or as

part of a LONWORKS FTT-10 Free Topology

communications network.

• Multiple controllers on a LonWorks FTT network

creates a complex network of controllers for virtually

any building control needs.

• Proportional (P) damper control and Proportional

Plus Integral (PI) for heating and cooling control.,

and Proportional Plus Integral and Derivative (PID)

control for cooling and heating.

• Onboard LED indication without cover removal.

• Plenum-rated enclosure allows direct mounting in

plenum.

• Protective hinged covers provide access to field

wiring terminals.

1) Dual-Mount Thermostat (Wall Thermostat) A) Use The dual-mount thermostat or "wall 'stat" is factory mounted in the unit for setpoint adjustment and diagnostics. As factory wired, this thermostat is NOT used to sense temperature. This thermostat may be removed from the unit and remotely mounted. In the remote location, the thermostat may be used for setpoint adjustment and diagnostics, but it can also be used to sense the space temperature.
PAGE 5
E) Remote Mounting (Wall Mounting) The dual-mount thermostat is factory mounted on the control panel. This thermostat may be mounted in the space for setpoint control and to sense the space temperature. This thermostat may be mounted directly to a wall, a 2x4 electrical box, a 1/4 DIN electrical box, or a surface mount electrical box. The sensor link (S-LK) wiring requires at least 24 gauge, twisted pair, voice grade telephone wire. Shielded wire is not required; however, this cable type is recommended.

(1) Thermostat Locking Cover - When a locking cover is required for a dual-mount thermostat that is mounted in the space, Invensys part AT-1155 may be used.
PAGE 7
C) Measurement & Scale At least one of the sensor wires must be disconnected from the controller before resistance measurements are taken. A digital multimeter or other low voltage ohmmeter may be used to measure the sensor resistance. Important: Units with water/steam coils are equipped with a low limit thermostat. This thermostat is wired in parallel with the outdoor air temperature sensor, such that the sensor is shorted when the thermostat closes for low limit conditions. Nominal Temperature vs.
PAGE 8
(4) The outdoor air damper position returns the percentage of full-scale output (20mA) being sent through the proportionally controlled actuator. Unlike the other display points, this is not a sensed value. This represents the percentage output of the control algorithm. B) Display of Controller Diagnostics with dual-mount thermostat This method will detect sensors that are out of the allowable scale, but it cannot detect a sensor that is out of calibration.
PAGE 9
D) Controller Lights (LEDs) The controller is equipped with 3 LEDs that are green (closest to edge of controller), yellow, and red (closest to center of controller). (1) Green - Power and Data Transmission LED. If this light is off, check controller power. Under operation conditions, this light should flicker or be ON. This light will flicker when data is being transmitted onto the communications network. (2) Yellow - Data Reception LED.
PAGE 10
B) Face and Bypass Damper Actuator This non-spring return actuator is connected to 24 VAC power and is controlled with a 4-20 mA signal from Analog Output 2 (AO2, #21). A 4 mA signal drives the damper into full bypass position (closed), while a 20 mA signal drives the actuator to the full face position (open). C) 2-Pipe Valve Controlled Unit A proportional valve is used on all 2-pipe (steam, chilled water and/or hot water) units.
