Press SET again.
Display will change to show the SEt.2 pressure setting.
Press +or -to adjust.
This setting is controlled based upon an external signal from, for
example a HP11 thermostat. This can provide a “cold outside tem-
perature” pressure setting.
(This setting is only used when the SEt.2 Input contact is closed.)
Press SET again to return to the current pressure reading.
VIEWINGPress INLET 1.
INLET 1 button indicator will illuminate and the display will
change to show the current position of inlet 1.
Press INLET 2.
INLET 2 button indicator will illuminate and the display will
change to show the current position of inlet 2.
If INLET 2 is disabled (n.inL=1 (see COSt settings)) and INLET 2
is pressed the display will change to indicate no operation:
These lamps illuminate to indicate the control condition.
When MIN is lit this indicates that the minimum set position is active. When this light is
not lit the minimum set position is set at 0%
When MAX is lit this indicates that the maximum set position is active. When this light is
not lit the maximum set position is set at 100%.
These lamps illuminate to show the current state of the inlet control.
When CLOSE is lit this indicates that the controller is closing the inlet.
When OPEN is lit this indicates that the controller is opening the inlet.
This lamp is illuminated when the SEt.2 Input Contact is made. When this lamps is lit
the controller runs the inlets to the SEt.2 pressure setting (See MAIN SETTINGS).

Press and hold INLET 2.
Display will change to show the start of the calibration procedure:
Continue to hold INLET 2 until the display changes to read the
potentiometer readout:
Release INLET 2.
The controller will drive the inlet fully closed (ensure that the
auto-manual switch is in the auto position).
When the inlets are in the fully closed position and the
potentiometer readout has stopped moving press INLET 2.
The controller will drive the inlet fully open.
When the inlets are in the fully open position and the
potentiometer readout has stopped moving press INLET 2.
The calibration procedure is complete.
The display will change to show the current inlet position.

SNUBBER DIAGRAM
If operating 240 volt relays or contactors, you must:
a) Ensure that common feed (terminals 3, 5, 7 & 9) is supplied via a 4 amp fuse.
b) A snubber network (supplied as an extra) is connected across the coil of the
contactor.

INSTALLATION
For correct installation, follow the instructions below very carefully.
It is recommended to install the controller properly so that it complies with current regulations, and also
to use a max 4Amp.F fuse to prevent the relay output contacts from getting damaged and ensure they
stay in perfect running order (terminals 3-4... 9-10 of the HP module connector).
How to connect the potentiometers and Input contacts
Connectthepotentiometer providedasshown in the diagrambelow:connectthe1 Kohmpotentiometer
(max 10Kohm) applied to the flap motor.
For remote connections use a standard 0.5-square millimetre two-pole wire for each potentiometer,
taking great care over the connections, by insulating and sealing any joins carefully.
How to connect the line
Connect line on terminals L-N; protect supply with adequate fuse.
How to connect the contacts
Connect terminals 3-4...9-10 on the terminal block (contacts up to 4AMP.AC1) to the inlet power pack
as shown in the diagram below.
