1) Start by removing the service hatch. Remove the 4 fixing screws, at the top and in the corners. There
is a Din Rail revealed once the service hatch has been removed.
) Use the cable grommets to bring the cables into and out of the controller base .
3) Connect the Mains IN as follows, Neutral blue wire to terminal #1 – Neutral IN, Live brown wire to
terminal # – L1 IN, Live black wire to terminal #3 – L2 IN, Live grey wire to terminal #4 – L3 IN.
4) There are two methods on how to connect the Infrared Heaters to the controller. a)
Connect the heater or heaters Live to O/P1 terminal #5 switche L1, the O/P has a maximum load
capacity of 8Kw or 40amps. O/P1 can also be referred to as Zone 1. Connect the heater Neutrals to
Neutral Out terminals #8 – 13. The heater Earth is connected to the Earth terminal #14. The remaining
heaters should be distributed across the remaining two outputs O/P & O/P3. Please ensure that the
loa is balance across the output terminals #5 – 7. Do not excee the maximum loa capacity per
output. b) Connect to an
external distribution box. Connect O/P1 to terminals marked 1, O/P to terminals marked 2 and O/P3 to
terminals marked 3. Connect the Neutral OUT to the blue terminals marked N. Connect the Earth to the
green/yellow Earth terminals. Then connect the heaters to the other side of the terminals to the
appropriate connections. Live connections to terminals 1,2&3. Neutral connections to blue terminals N
and Earth connections to the Earth terminals.
5) When all connections are complete and connected correctly, check once again that the wiring is correct as
per 3) & 4). Then replace the service hatch cover and tighten the fixing screws.
6) Turn ON or reconnect the Main Power to the controller. The red neon lamp on the front panel will
illuminate to indicate that the unit is LIVE.
7) There are auxiliary devices such as mains operated PIR motion detectors & timer (lag) switches. These
can be connected to terminals #15 – 17. External push button switches which are voltage clean or free
can be connected to terminals #18 – 0.
8) Remote operation ensure the Power control dial is in position R. Follow the instructions in page 3 for
QHVCR remote Master Controller .
9) Manual operation move the position of the dial through positions M, 1, 2, 3 & 4.
M = 0%, 1 = 33%, 2 = 50%, 3 = 66%, 4 = 100%

QHVCR remote Master Controller (transmitter)
1) 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, this will be the Blue control dial.
) Turn ON the QHVCR unit by pressing the ON/Standby button on the front panel. The Led
indicator will flash orange – green – orange – green and remain Green to indicate that the unit is
ready.
3) The QHCxxMR unit is preset as a Blue zone (1). Turn the Blue control dial to position 2. The
heaters connected to the QHC06MR units will come ON at the minimum setting 33%. Continue to
turn the Blue control dial through position 3 to 5 until you reach the desired setting. Settings are 1 =
0%, 2 = 33%, 3 = 50%, 4 = 66% & 5 = 100%.
4) QHCxxMR units which are preset to Yellow & Red zones are controlled by the Yellow & Red
control knobs respectively and will operate as above in 10).
5) The QHVCR unit is powered by 3 x AAA battery's. So, 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. The heaters will remain ON.
6) To change a setting just press the ON/Standby button and proceed as described in 9) & 10).
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 flashing Red.
7) The previous settings will be remembered and will be restored when you press the ON/Stand by
button again.
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 specification sheet for the QHVCR unit).
The QHVCR should be wall mounted.

Pairing (programming) evices
QHVCR & QHC24MR
Pairing (programming) evices QHVCR (transmitter) an QHC24MR (receivers).
1) The Left Hand Side rotary switches (TEN) on both boards must be set the same.
The LHS switch (TEN) is used to set the RF frequency the setting must match on both
boards. There are 10 possible frequencies that can be selected 0-9. If the settings on the LHS
switch (TEN) do not match the devices will fail to operate.
Designating the transmitter and receiver. Both the left rotary switches are set at 0,
this ensures that the transmitter marked 0 will communicate with the receiver marked 0.
Setting 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; transmitter marked 0 will not communicate with a
receiver marked 1.
Remember a transmitter can be set at any number between 0-9 & the receiver must be
matched correctly.
) The Right Hand Side rotary switches (UNIT) are for setting the devise to operate in a set
zone. There are 3 possible zones that the controller can be set to. The RHS switch (UNIT)
should be set to 1, or 3.
Blue Zone 1 operation set RHS switch (UNIT) to 1
Yellow Zone operation set RHS switch (UNIT) to 2
Re Zone 3 operation set RHS switch (UNIT) to 3
