Assembly Instructions
1. Isolate the Mains before removing the cover. Remove the cover by removing the 4
screws. There is a terminal strip connector for connecting the Mains IN and
Mains OUT.
2. Use the three cable glands to bring the Mains cables into and out of the
controller base.
3. Connect Mains IN - Live brown (2), Neutral blue (3) and Earth green/yellow (4) wires
to terminals marked Live IN (2), N IN (3) and Earth IN (4).
4. Connect the Infrared Heater - the brown Live wire to Load Out (7), the blue Neutral
wire to N Out (6) and the green/yellow Earth wire to Earth Out (5).
5. The trigger from a motion detector (PIR) QHPIR is connected to the terminal PIR
Input (1).
6. When all connections are complete and connected correctly, check once again that
the wiring is correct as per steps above - 3 & 4. Then replace the cover and tighten
the xing screws.
7. Turn ON or reconnect the Main Power to the controller. The red neon lamp on the
LHS will illuminate to indicate that the unit is LIVE.
The controller is now ready to be controlled by the wireless remote unit QHVCR. See
instructions for QHVCR operation, page 7 follow steps 8 to 14.
Only a qualied electrician should install this device. Fit Type C MCB circuit breakers
and a fused spur for each heater.

QHVCR Master Controller (Transmitter)
QHVCR Master Controller (Transmitter)
8. There are three control dials Blue, Yellow & Red one for each zone. The QHCxxMR
units are preset to operate in one of these zones. The QHCxxMR unit once preset
will only operate in that designated zone. The factory setting is 1, which is the Blue
control dial.
9. Turn ON the QHVCR unit by pressing the ON/Standby button on the front panel.
The Led indicator will ash orange – green – orange – green and remain Green to
indicate that the unit is ready.
10. The QHCxxMR unit is preset as a Blue zone (1). Turn the Blue control dial to
position 2. The heaters connected to the QHCxxMR units will come ON at the
minimum setting 33%. Continue to turn the Blue control dial through positions 3 to 5
until you reach the desired setting.
Settings are 1= 0%, 2= 33%, 3= 50%, 4= 66% & 5= 100%.
11. QHCxxMR units which are preset to Yellow & Red zones are controlled by the Yellow
& Red control dials respectively and will operate as above.
12. The QHVCR unit is powered by 3 x AAA batteries. The unit will automatically go into
standby mode if the unit is inactive for more than 30 seconds. When the unit goes
into standby mode all the QHCxxMR units will remain unchanged at the settings they
were set at. Therefore the heaters will remain ON.
13. To change a setting just press the ON/Standby button and proceed as described in
2) & 3). However, while the QHVCR unit is ON, you can turn OFF all the heaters by
pressing the ON/Standby button. This is indicated by the Led indicator ashing Red.
14. The previous settings will be remembered and will be restored when you press the
ON/Stand by button again.

8QHVCR Master Controller (Transmitter)
Please note: The QHVCR remote Master Controller can control any number of QHCxxMR
controllers as long as they are within range, up to 100 meters* (see specication sheet
for the QHVCR unit). The QHVCR should be wall mounted.
*Longer antennae are available to extend the range up to 200 meters.

Pairing Programming DevicesQHVCR & QHCxxMR
Pairing Programming Devices
QHVCR & QHCxxMR
1. The Left Hand Side rotary switches (TEN) on both boards must be set the same. The
RF frequency setting must match on both boards. There are 10 possible frequencies
that can be selected from 0-9. If the settings on the LHS switch (TEN) do not match
the devices will fail to operate.
When designating the transmitter and receiver, ensure both the left rotary switches are
set at 0, this ensures that the transmitter marked 0 will communicate with the receiver
marked 0. Set the left rotary switch to 1, so the transmitter marked 1 will communicate
with a receiver also marked 1.
If the transmitter and receiver are not paired correctly they will not communicate and
therefore will not operate. A transmitter marked 0 will not communicate with a receiver
marked 1.
The transmitter and receiver must be set to the same number for them to communicate.
2. The Right Hand Side rotary switches (UNIT) are for setting the device to operate in a
set zone. There are 3 possible zones that the controller can be set to:
Blue Zone for 1, Yellow Zone for 2, and Red Zone for 3.
Note: QHCxxMR = QHC06MR, QHC18MR, or QHC24MR

10 PIRMotionDetectorsConnection&Operation
PIR Motion Detectors Connection
& Operation
PIR motion detectors are passive infrared sensors and
electronic devices that are triggered by infrared light from the
movement of objects in their eld of view.
We recommend the QHPIR is used with our QHC controllers.
Connecting the PIR to the QHCxxMR will enable the controller
to turn ON only once the presence of a person is detected by
the PIR.
The angle of the PIR and the viewing width of the lens needs
to be adjusted to ensure you target the desired detection area.
Full lens width will have a large detection area. For smaller
area, the lens narrows the lens using the lens mask.
Setting the Lens width correctly is crucial, if it’s set incorrectly
the PIR could be continuously be ON, causing the heaters to
remain ON too.
Connect the switched trigger to terminal #1 PIR Input on the
QHC06MR controller.
The switched Live OUT to the QHC06MR controller is a Live
240V feed, this is only used as a signal Input to the controller.

7-Day Programmable Timer Fitting Option
7-Day Programmable Timer Fitting Option
A 7-Day programmable timer can be tted as an option instead of the PIR. It is important
to note that only one or the other can be tted to the QHCxxMR controller, not both.
S1 & S2 are found on the printed circuit board (PCB) QHPCB-A, See Fig 12.
Default Settings for S1 & S2
Remote OFF - S1.Jumper is factory set to the OFF position pins 2& 3. For Manual
operation, PIR & 7-Day Timer OFF - S2. Slide switch is factory set to the OFF position 2,
see Fig 12.
Setting Up a 7-Day Programmable Timer
The S2 Slide switch must be set to the ON position 1.
Fig 12, Slide switch S2 is in the OFF position. Fig 13, a typical 7-Day Programmable Timer.
Fig 14, wiring connection to the QHCxxM
& MR controller
The switched Live through A2 terminal on the
7-Day timer is connected to terminals
#15, 16 & 17 on DIN Rail connections of the QH-
CxxM & MR controller. A Jumper Link must be
tted to terminals #15, 16 & 17 so that the three
outputs will operate together as one.
Once the 7-Day programmable timer is tted
correctly it will now control when the controller
will be ON or OFF, see Fig 14. This function can
be disabled by simply switching the S2 slide
switch back to the OFF position 2, see Fig 12.

12 Expandable Heating System
Expandable Heating System
Using a QHVCR & Multiple QHC03MR,
QHC06MR & QHC09MR Controllers
Using the remote 3-zone QHVCR controller the area being heated can be zoned into three
area’s Blue, Yellow & Red. Each zone can be controlled separately, this includes setting
each zone at a different level.
The 5 setting levels are > Off – 1 (33%) - 2 (50%) - 3 (66%) - 4 (100%).
Any QHC controller can be used in the proposed zoned layout below. The controllers
available are 3kW QHC03MR, 6kW QHC06MR & 18kW QHC18MR which can be used
depending on the overall number of heaters required.

1. The QHCxxMR (receiver) is not working:
Check that the unit is wired correctly and follow the installation procedure on page 6. The
neon indicator should be ON to indicate that the Mains are connected correctly.
Then check that the status LED D5, the +5v LED D6 & the +12v LED D7 are all ON green. If
the status LED is Red, this indicates that there is a problem with the mains connection to
the board.
If the +5v or +12v LEDs are Red this indicates that there is a problem with the processor
chip or a power supply problem.
2. There is no communication between the QHCxxMR & QHVCR:
This means the units may not be paired correctly. First, determine what frequency the
QHVCR is set at. The setting is marked at the back of the unit. If it’s marked (0) you must
check to see if the QHCxxMR is also set the same and is also marked (0). If they are
different then the controller QHCxxMR will not work.
If needed you can reset the controller QHC06MR by following the Pairing instructions on
page 9.
3. Paired transmitter QHVCR & receiver QHCxxMR won’t communicate even when they
are both set the same:
The small antenna RF PCB could be the problem. Check if the small LED ashes Red
when the transmitter QHVCR is turned ON & OFF. If the LED ashes Red, it means the
communication between the two devices is good. Otherwise, if the LED remains ON
Green then the RF PCB is faulty and needs to be replaced.
However, if the RF PCB is working and the LED ashes Red but the controller QHCxxMR
is still not working, the cable connection between the RF PCB and the Antenna could be
faulty and may need to be replaced.
4. The yellow zone is not working:
The problem could be the receiver is set as a blue zone or red zone. If this is the case all
you have to do is re-set the right-hand rotary switch to position 2.
5. The circuit Breaker MCB keeps tripping when the heaters are turned ON:
Ensure that the MCB is a Type C where there are likely to be surges. A common fault is
using Type B circuit breakers instead but this will always fail. Replace with Type C and the
problem should be xed.
6. The controller does not respond to settings 3 & 4:
Check for a loose or missing Black connector ref. J8 (TMP2) header on the printed circuit
board (PCB).
