2. Air Duct Mode (All Generations): Air Duct Mode
(ADM) allows for the control of Zone Temperature
based on the return air temperature as sensed in the
air duct. To activate ADM turn (BV:41) to “ON” and
BV:44 to “ON”. This requires a 10KΩ type II Duct
Sensor brought into the MPC unit across the TEMP
Input and GND Input on the LSTAT Connector.
3. Cooling Only or Heating Only Setup (Generation
7 only): For applications in which is desired to run
in a heating or cooling only mode use the following
control points to accomplish this.
a: Heating Mode Enabled- (BV:53) will enable the
Heating Mode when checked. It defaults to
checked so Heating Mode is enabled on
startup. Useful when you wish to run in a
Cooling only mode as it allows the turning
off, of the Heating Mode.
b: Cooling Mode Enable – (BV:54) will enable
the Cooing Mode when checked. It defaults
to checked so Cooling Mode is enabled
on startup. Useful when you wish to run in
a Cooling only mode as it allows the
turning off, of the Cooling Mode.
4. Load Balancing Mode (Generation 7 only): Denes
the mode of operation for the runtime balancing of
a 2 Compressor application. The modes are set by
entering the following in (AV:59):
a: AV:59 = 01- Runtime comparison mode - The
compressor with the least runtime becomes
the stage 1 compressor while the high time
compressor becomes the stage 2 compressor.
b: AV:59 = 02- Manual C1 is Stage 1, C2 is Stage.
c: AV:59 = 03- Manual C2 is Stage 1 and C1
is Stage 2.
d: AV:59 = 04- Time Toggle- C1 and c2 swap
stages every 12 hours dependent
on demand.
5. Compressor Shutdown (Generation 7 only):
There are times when it is desired to disable the
compressor via the BMS. This is accomplished by
Turning (BV: 52) to “OFF”.
6. Manual Setpoint Adjust (All Generations): Sets
the maximum amount (degrees) by which the user
can adjust the zone's setpoints from a zone sensor.
The adjustment range is dened as +/- the value of
Manual SP Adjust. Example: If Manual SP Adjust is =
2 the adjustment range would be +/- degrees from
the Master Zone Temperature (72°) or from 70° to
74°. You enter the Manual setpoint value via (AV:37)
or AV:44 depending on your temperature setting
(F° or C°).
7. Dirty Filter Detection Setup Options (All
Generations): All Generations of the MPC can
use Time to determine the when to replace the
air lter. Generation 7 can also use an external air
pressure sensor in addition to xed Time method
to determine when to replace the air lter. All
Generations default to Time Mode which is
nominally set to 1500 Hours. This of course can
be changed via (AV: 30).
Setup for Air Pressure sensor is covered below:
a: Dirty Filter Sensor- Setting (BV:59) to “ON”
allows Dry Contact Input 6 (SW, GND) to
function as pressure input. This requires
a pressure switch on the output side of
the return air lter. (User supplied)
b: Dirty Filter Mode: Set (BV:60) to Pressure.
8. Conguring the Supply Fan (All Generations):
(AV:33) is used to control the action and behavior of
the supply fan.
1 => FAN is “ON” by demand, Occupied
or Unoccupied.
2 => FAN is “ON” while Occupied and
ON by demand in unoccupied hours.
3 => FAN is ”ON” all the time.
9. Test Mode (All Generations): Test Mode is used
to test the output functions of the MPC unit This
conguration will only remain active for 30 Minutes.
To put the Unit into Test Mode, turn on (BV:34). Once
in Test Mode the following can be tested in the
indicated order.
1: (BV:28) Supply Fan Manual “ON”
2: (BV: 30) C1 Manual “ON”
3: (BV: 31) C2 Manual “ON”
4: (BV: 32) AUX Manual “ON”
5: (BV: RV) Manual “ON”
10. Input 5 and 6: (Generation 5-7): These Generations
allow the user to use Input 5 (TEMP, GND) and Input
6 (SW, GND) for added features such as Temperature
monitoring, or current switch sensing applications.
With RNET Mode (BV:44) “ON”, inputs 5 and 6 will
monitor eld supplied 10KΩ type II thermistors via
Aux5 Temp (AV:50) and Aux6 Temp AV51. If a dry
contact input is desired, activate Aux% CFG, BV:46
and /or Aux6 CFG, (BV:47). This will allow the user to
monitor switch closure status at Aux%, ((BV:42) and /
or Aux6, (BV:43).
