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%
