Description
The Prolon PL-C1000 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 Prolon zone controllers.
The Standalone model of this controller will not act as a master to other Prolon zone controllers, relying instead on the
demand provided by a local sensor.
General Behaviour
Although fully congurable, the Prolon C1000 Heatpump controller uses pre-established control sequences or ’’pro-
les’’ to operate specic 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 modication or ne tuning of the fan, the
compressor outputs, the action of the heating outputs (On-or-O / pulsed / modulating), the proportional bands,
integration times, dierentials, operational ranges, setpoints and a whole range of limits and safeguards. The various
programming options also allow the user to modify 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.

Operating Sequence
General
The Prolon C1000 Heatpump controller receives readings from three dierent temperature sensors: outside air, return
air and supply air. Also, as a Master device, it receives data from the zone controllers or thermostats sent on the net-
work 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. When
working as a network Master, it sends back information to 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. 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 satised, the outputs are deactivated within the
prescribed minimum on/o 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 congured for water-to-air
mode, the low balance point is ignored and the use of compressors is permitted all year round. Protection sequences
are in place that will activate auxiliary heat upon failure of the compressors. Once the demand is satised, the outputs
are deactivated within the prescribed minimum on/o time delays.
When there is no cooling or heating demand from the zones, only the fan is enabled. 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 com-
fortable level for subsequent use by the zones for ventilation.
Unoccupied Mode
The fan can be congured to operate in intermittent mode. When there is a cooling or heating demand from any
single zone, the Heatpump controller will activate the fan and the necessary cooling or heating outputs as long as all
temperature limits, delays and other related parameter are respected. Once the demand is satised, the fan and any
cooling/heating outputs are deactivated within the minimum on/o time delays set.
During the unoccupied period, the Heatpump controller can be driven by the highest demand on the network and
will operate the fan and relevant outputs accordingly.

Input and Output Identification
All the inputs and outputs of the C1000 use pluggable screw type terminal blocks with elevator style clamping, which
make connections easier and more secure. Output functionality will vary depending on the number of compressors
in use (1 or 2 - see below).
The C1000 Heatpump Controller has 2 separate communication ports oering varying functionality based on whether
or it is a heatpump standalone controller (HPS) or not (HP).
The “INT” Port (see below) uses an RJ45 type connector. The RJ45 connector allows the use of premade CAT5 cables for
simple plug-and-play RS485 communication. This RJ45 connector follows the Modbus pinout specication for RS485
communication.

Addressing Dipswitch Configuration for Network Communication
Jumper to Supply Power to the RJ45 Plug
A unique address must be congured on each controller by setting the rst 7 switches on the addressing dipswitch
to the desired value.
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 respec-
tively). 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.
The example in Figure 1 shows 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.
Figure 5 - Addressing Dipswitches
Figure 6 - Jumper
The RJ45 jumper lets the user select if 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 a digital sensor or interface. NOTE: If multiple C1000 controllers are connected
together through the RJ45 plug, only one C1000 should be supplying power onto the RJ45, otherwise you will be
mixing your supply sources and possibly cause damage. The jumper setups are as follows:
No power 24 VAC 24 VDC

Inputs
Temperature Sensors
he C1000 Heatpump controller has three analog inputs that monitor outside air, return air and supply air temperatures
(see Figure 2) and will integrate these readings into its control sequence. The sensors used are standard 10k type 3
thermistors that share a single common connection.
Alternatively, the supply air temperature can be retrieved from a zone controller that has its own supply sensor and
belongs to the C1000’s network.
The outside air temperature can be also be provided by an alternate source. If a network controller is present on the
network, it can retrieve the outside temperature reading from one controller and distribute it to any other controllers
on the network.

Occupancy Mode (Night Setback)
Figure 8 - Night Setback Contact Connection
Temperature setback savings can be obtained by using a dry contact originating from an external timer to switch
the controller from occupied to unoccupied mode. The timer contact used must be connected to the "OCC" and the
"GND" terminals (see Figure 8). To indicate occupied mode, the contact must be open. To indicate unoccupied mode,
the contact must be closed. If operating as a network Master, the Heatpump controller will then send the occupancy
status to all known slaves on his network. NOTE: This input can instead be used as a prof of fan input, depending on
the software conguration. Alternatively, occupancy can be supplied by the NC2000 network controller.

The C1000 Heatpump controller contains 5 customizable outputs, 4 being Triac type switch outputs and one being
0-10Vdc analog modulating / pulsed / On-or-O output. Some outputs are congurable and follow a proportional and
integral algorithm (PI) to ensure precise adjustment of the device. Output conguration is performed via the Prolon
Focus software.
An integrated resettable fuse protects each of the four Triac outputs of the C1000 against current surges and short
circuits. This protection will cut the current to the output as soon as an overload condition is detected. It consists of
a round yellow-coloured thermal fuse that will change to orange and heat up on a short circuit condition. When the
faulty wiring or circuit is xed, the breaker will automatically reset and activate the output again.

Typical Connection of the Triac Outputs 1 Through 4
Typical Connection of Output #5
On the C1000 Heatpump controller, all triac outputs must be set to SOURCE mode because they all share a single
source supply: the equipment’s transformer. All triac outputs have a SOURCE / SINK conguration switch; they must
be set to “SWITCH” (move switch towards terminal blocks). Only the terminal blocks marked 24 VAC are used for each
output.
Output 5 is an analog output 0-10 VDC. It can be congured to modulate a 0@10 VDC load, to pulse a 0 or 10 VDC Triac
relay or to control a 10 VDC On/O relay.

Power Source / Network
Power Source
Network Communication
The Prolon controller is powered by the HVAC equipment’s 24 VAC supply by connecting the common or ’’C’’ wire to
the "COM" terminal and the live or ‘’R’’ wire to the "24 VAC" terminal (see Figure 13). The common for all inputs and
outputs is the same as the power source’s common. All output power sources also originate from the controller’s
power source.
Figure 13 - Connecting the 24VAC Power Source
Figure 14 - Connecting to the Network
The Prolon C1000 Heatpump controller is primarily designed to work with Prolon zone controllers. When they are net-
worked, the Heatpump and zones all communicate in real-time using Modbus RTU protocol over RS485. The network
connections are made using the NET terminal block located on the Prolon controller.
