GENERAL INFORMATION
PL-M1000 Heatpump Controller
Description
The ProLon PL-M1000 Heatpump controller
is a microprocessor-based controller
designed to operate residential or commercial
heatpump equipment. It uses PI
(Proportional-Integral) control loops and acts
as a master when used on a network with PL-
VC1000 zone controllers.
General Behaviour
Although fully programmable, the ProLon M1000 Heatpump controller uses pre-established control
sequences or ’’profiles’’ to operate specific HVAC equipment with dedicated output functions. These
can be fully optimized to obtain the best results for each type of system. Numerous parameters
enable the modification or fine tuning of the fan, the compressor outputs, the action of the heating
outputs (On-or-Off / pulsed / modulating), the proportional bands, integration times, differentials,
operational ranges, setpoints and a whole range of limits and safeguards. The various programming
options also allow the user to modify the schedule, unoccupied mode settings, morning warm-up and
supply air pre-heating sequences as well as the network demand control strategy best suited for the
building space it is controlling. All these parameters can be accessed by using the ProLon Focus
software or with the ProLon handheld digital interface (PL-HNI).

Operation Sequence
General
The ProLon M1000 Heatpump controller receives readings from three different temperature sensors:
outside air, return air and supply air. It operates on a configurable schedule using an internal real-
time clock. Also, as a Master device, it receives data from the zone controllers sent on the network
bus. The controller then analyzes all the data and demands sent by the zones and commands the
appropriate outputs to respond accordingly, within parameters set by the temperature sensors and
other safety limits. The Master sends back information on its network such as supply air
temperature, occupancy status and other relevant data for the zone controllers to use.
Occupied Mode
The controller operates the fan continuously. When there is a cooling demand from the zones, the
Heatpump controller will put the reversing valve into cooling mode and activate the compressor
outputs as long as all temperature limits, delays and other related parameters are respected. Once
the demand is satisfied, the outputs are deactivated within the prescribed minimum on/off time
delays.
When there is a heating demand from the zones and the outside temperature is above the low
balance point, the Heatpump controller will put the reversing valve into heating mode and activate
the compressor outputs as long as all temperature limits, delays and other related parameters are
respected. If the outside temperature is below the low balance point, the controller will activate the
auxiliary heating outputs. If the heatpump is configured for water-to-air mode, it will only use the
compressor for heating. Once the demand is satisfied, the outputs are deactivated within the
prescribed minimum on/off time delays.
When there is no cooling or heating demand from the zones, only the fan operates. If the heating
equipment permits, a supply air pre-heating sequence may be enabled. This allows cold mixed air to
be heated to a more comfortable level for subsequent use by the zones for ventilation.

Unoccupied Mode
The fan operates in intermittent mode. When there is a cooling demand from any single zone, the
Heatpump controller will activate the fan and the compressor outputs as long as all temperature
limits, delays and other related parameters are respected. Once the demand is satisfied, the fan and
cooling outputs are deactivated within the min. on/off time delays set.
When there is a heating demand from any zone, the Heatpump controller will activate the fan and
the heating outputs as long as all temperature limits, delays and other related parameter are
respected. Once the demand is satisfied, the fan and heating outputs are deactivated within the min.
on/off time delays set.
During the unoccupied period, the Heatpump controller is driven by the highest demand on the
network and will operate the fan and relevant outputs accordingly.

LEDs and Switches
The M1000 has an LED block on the front of the casing whose LEDs are linked to different functions
and outputs of the controller. Each LED is individually identified to help the user make a quick visual
diagnostic of the controller’s activity and status.
LED Descriptions:
•24 VAC: The M1000 is receiving 24 VAC from the power source.

•5V DC: The microchip and other components on the M1000 are powered by a 5V
DC source successfully derived from the 24VAC source.
•HBEAT: When this LED is blinking, the microchip is active and the controller’s
program is running (normal). When this LED is ON and steady, the M1000 is
inactive and the microchip is awaiting programming (you must use ProLon’s
Focus software to reprogram the microchip).
•STAT: When lit, indicates the M1000 is using BACnet communication protocol
instead of Modbus on the RS485 communication port.
•NETREC: Indicates reception of data from the network communication bus.
•NETSND: Indicates transmission of data onto the network communication bus.
•INTREC: Indicates reception of data from the interface communication bus.
•INTSND: Indicates transmission of data onto the interface communication bus.
•AO3: The intensity of the LED represents the voltage present on analog output 3.
•AO2: The intensity of the LED represents the voltage present on analog output 2.
•AO1: The intensity of the LED represents the voltage present on analog output 1.
•DO5: Represents the activity of digital output 5.
•DO4: Represents the activity of digital output 4.
•DO3: Represents the activity of digital output 3.
•DO2: Represents the activity of digital output 2.
•DO1: Represents the activity of digital output 1.
HAND/OFF/AUTO Switches
Each output on the M1000 has a dedicated switch that lets the user manually override the activity of
the output. “HAND” mode (switch at leftmost position) fully activates the output (24 VAC for digital
outputs, 10VDC for analog outputs). “OFF” (switch at center) deactivates the output and “AUTO”
(switch at right) returns control of the output to the program in the M1000’s microchip.

Internal Jumpers
The M1000 has several sets of jumpers
on the lower internal board that permit the
configuration of various hardware
elements (see Figure 1).
RJ45: The RJ45 jumper lets the user
select the voltage that will appear on pin
#7 of the RJ45 plug. This can be used to
power a device attached to the RJ45
plug, such as the PL-HNI digital interface.
NOTE: If multiple M1000 controllers are
connected together through the RJ45
plug, only one M1000 should be
supplying power onto the RJ45,
otherwise you will be mixing your supply
sources and possibly cause damage. The
jumper setups are as follow

Input and Output Identification
All the inputs and outputs of the controller use "Plug-In" type screw connectors. The connectors used
for interface communication and programming are dual RJ45 type connectors, which are wired in
parallel with each other (one in, one out). With these connectors, the wiring can be done quickly and
much more easily.

Addressing Dipswitch Configuration for Network
Communication
For proper communication, a unique address must be configured on
each controller by setting the first 7 switches on the addressing
dipswitch to the desired value.
1234567
These switches are numbered from 1 to 7 and represent a binary
value from 1 to 64 (1, 2, 4, 8, 16, 32, and 64 respectively). The last
switch (#8) is reserved. The value of each switch that is in the ON
position is added together to form the numerical address of the
controller.
Figure 2: Addressing Dipswitch
The example in Figure 2shows the switches 1, 2 and 4 in the ON position. Therefore, the corresponding
values are 1, 2 and 8, giving an address sum of 11.
The ProLon network allows a maximum of 127 addresses, therefore 127 controllers.
