escription
The Marvair MPC-10 is an HVAC controller designed to control up to ten air
conditioners, that can be either single or dual compressor, for equipment enclosures.
In addition to the control of the air conditioners, the MPC-10 provides alarms
remotely, through BACnet or Modbus, and locally using a built-in Human Machine
Interface (HMI). The controller is factory programmed with standard industry set
points, but can be configured on site or remotely. Settings are retained indefinitely
in the event of a power loss.
➤
Control Up to Ten Air Conditioners in a Shelter
The MPC-10 offers the ability to stage cooling and heating operation for both
dual and single circuit PLC equipped units. This gives the controller a maximum
of 20 stages of cooling for dual circuit units, 10 stages of cooling for single
circuit units, and 10 stages of heating.
➤
Ease of Control and Configuration
The MPC-10 comes standard with a 7-inch color touchscreen HMI which provides
a user-friendly interface. From the main screen of the HMI the user can see room
conditions, HVAC status for each unit, and change cooling/heating set points.
The statuses that can be displayed for each unit are as follows: Cooling, Heating,
Blower, Fault, Standby, Shutdown, and T-Stat Off. If a fault occurs an alarm
window will pop-up that displays a description of the alarm, the time/date at
which it occurred, and the current status of the alarm. Along with the pop-up an
alarm button will appear which allows the user to minimize/maximize the alarm
window. The alarms will be maintained until the fault is fixed and the alarm is
cleared.
The initial setup of the MPC-10 will be done from the built-in HMI. During this
process the user will input the number of units, whether the units are dual or
singe circuit, and the desired communication protocol. Once the initial setup is
complete all other parameters can be changed, at any time, from the 2nd page of
the HMI (F2 Button) or remotely.
