The following components are supplied in a
box taped inside the supply air spigot:
1. SAT-2 Wall Control plaque, including wall
mounting plate.
2. 10 m interface lead (electrical box-to-
plaque).
3. User's Operating Instructions booklet.
4. Lithium CR2032 battery (3V).
Optional
1. Remote return air sensor (in box).
2. Remote return air temperature sensor
lead; 1.5, 6, 12 or 25 m.
3. 20 m extended interface lead
(electrical box-to-plaque).
4. SAT-2 Zone Control PCB.
5. Zone Control 24V transformer.
6. Additional SAT-2 Wall Control plaque.
7. Infra red remote control.
The SAT-2 Controller PCB is supplied pre-
installed in the HWP unit's electrical box.
1. Isolate the HWP unit from power supply,
then remove electrical box cover.
2. Remove the SAT-2 box supplied taped
inside the supply air spigot.
3. Remove the Wall Control's interface lead
from this box and connect to the terminal
block (A1/B1/Vcc/GND) on the SAT-2
Controller board. Trace the remaining
length of the lead to the Wall Control's
intended location. : Make sure the
coloured wires are connected as per the
wiring diagram.
4. Remove the Wall Control's backing plate
by using a small screw driver to remove
the single screw at the bottom edge of
the plaque.
5. Install the Lithium battery, supplied loose,
positive (+) side up in the Wall Control's
battery holder.
6. Check the wall where the Wall Control
plaque is to be located is at before
fastening the wall mounting plate.
Alternatively, the mounting plate can
be screwed to a standard wall socket
mounted horizontally.
: Use low prole (mush) headed
screws to prevent contact with the PCB
board. Fixing the plate to a distorted
surface may damage the control.
7. Drill hole in wall to allow cable entry.
8. Connect the interface lead to the the
Wall Control board. : Make sure
the coloured wires are consistently
connected at each end as per the wiring
diagram.
9. Ensure the interface lead is run
separately and away from main
power supply wires, including the
interconnecting cable. When installing
cabling, trim any excess length to suit
your location.
10. Fill around the interface lead with foam
or cover hole with PVC tape to prevent
draft from wall cavity affecting control
operation. Do not use aluminium duct tape.
11. Secure the Wall Control body to the
mounting plate by replacing the locking
screw removed earlier.
12.Replace the HWP electrical box cover.
Units Supplied With SAT-2 Thermostat
Any faults detected are displayed on the
SAT-2 Wall plaque (refer Table 1). A non-
specic fault output signal is also included
on SAT-2 Controllers for remote fault
indication to building management systems.
Units Supplied With Electric Heat
HWPSCEKS models supplied with electric
heat include both auto (90°C) and manual
(120°C) high temp. safety thermostats. If the
manual safety t/stat requires resetting, then
the auto safety t/stat has failed and needs to
be replaced.
(Reverse Cycle Models)
The thermostat should be set within the
recommended operating range of between
19°C and 30°C. The thermostat should
not be used as an on-off switch. Refer to
for a list of other approved
thermostats.
If your unit is supplied with 's
, refer to page 3 for
installation instructions.
1. Check that the thermostat is
correctly wired and set at the desired
temperature.
2. Check that the air lter (if tted) is clean.
3. Check that the fan runs freely without
vibration.
4. Check condensate drain and safety
drain tray for free drainage.
Demonstrate the SAT-2 Wall Control (if
supplied) to the owner/user, after having
rst thoroughly familiarised yourself with the
User's Operating Instructions. This page is
to remain with the owner/user.
1. Remove lint and dust accumulation from
heat exchange air coil. (Note: failure to
do this may affect efciency).
2. Check air lters and vacuum or wash
clean as necessary.
3. Check condensate drain for free
drainage.
4. Check compressor compartment for oil
stains indicating refrigerant leaks.
5. Check quality of water supply.
Check tightness of electrical connections.
1. Remove lint and dust accumulation from
heat exchange air coil. (Note: failure to
do this may affect efciency).
2. Replace air lter if damaged to maintain
adequate air ow and efciency.
The manufacturer reserves the right to
make changes in specications at any time
without notice or obligation. Certied data is
available on request.
This pamphlet replaces the previous
issue no. 3905 dated 11/13. Indoor fan
speed adjustment; wiring revisions.
The air temperature sensor is by default
located in the Wall plaque. Optional remote
air temperature sensors are available
so that the measurement of the room
temperature can be taken away from the
wall plaque, eg. elsewhere in the room or in
the return air duct.
Remote sensor's can be plugged directly
into the Controller board (PCB). This
board accepts up to four sensors which
are designated as 'zones' one to four. The
rst return air sensor will automatically
replace the Wall Control sensor and should
be located in the same room as the Wall
Control. The Controller will always use the
average of the zones selected. Refer to the
separate installation instructions supplied
with the PCB for further details.
Ensure all remote sensor wires are run
separately and away from main power
supply wires, including the interconnecting
cable.
Any faults detected are displayed on the
SAT-2 Wall plaque (refer Table 1 overleaf).
A non-specic fault output signal is also
included on SAT-2 Controllers for remote
fault indication to building management
systems.
