AlphaStat-Plus Mounting.
Where to mount the AlphaStat-Plus.
1. Against a flat vertical surface with sufficient strength to hold the enclosure and any additional
weight from the plugs, sockets and cables.
2. Power leads must be facing directly down, not sideways or up.
3. Safe for users to inspect.
4. The display can be easily read and buttons accessed.
5. Allow for cable runs, location of power outlets and lengths of wires.
6. Allow space for SolaStat-Rly if used to control the hot water tank electric element.
Mounting the AlphaStat-Plus.
1. There is no need to open the enclosure during a standard installation.
2. Allow for the enclosure dropping 5mm from screw centres once mounted (keyhole mounting
system).
3. Place drill guide template against wall, checking for level alignment. 4 screws are supplied, 2
are chip board screws and 2 are combination Gib/ wood screws. It is recommended that all
4 mounting holes are used with at least 2 firmly secured into wood. The outer plastic Gib
anchors will self tap into Gib board and their inner metal screws fix into the centre of the
plastic anchors.
4. Mark and drill/ screw as appropriate leaving the heads of the screws above the surface by
approximately 3mm.
5. Place unit over the 4 screw heads, unit should slide down 5mm into the ‘key’ slots and
become secured to the wall. You will need to adjust screw height to obtain a secure fit.
Mounting the Sensor.
This is Critical to the Success of the Installation.
The sensor is the only way the AlphaStat-Plus can efficiently control and protect the system.
The ‘TANK’ Sensor should always be installed above the HWC electric element for the controller
to work efficiently.
The ‘TANK’ sensor is best fitted into a metal immersion ‘pocket’ in the upper region of the HWC. The
position of the Tank sensor will vary the amount of water in the HWC that will be controlled at the
required temperature. As an example for a 300l vertical tank mounting the sensor 1/3 of the way
down from the top of the HWC will give about 100l of water that is heated within the control
parameters. This increases efficiency as only the amount of water required in normal household
use is controlled rather than all the water in the HWC. The sensor must be mounted above the
electric element. Liberally apply heat transfer compound between the sensor and the lining of the
‘pocket’. If a ‘pocket’ is not available then bond the sensor against the metal wall of the tank (not
the outside cladding or insulation) using thermal transfer compound between the tank and sensor.
Warning.
1. Removing or cutting the cladding may void hot water tank warranty.
2. Sensor must not be immersed in water.
3. It is recommended that sensor leads be kept 300mm away from mains and comms cables.
4. Failure to properly mount the ‘Tank’ sensor as prescribed above can result in;
a. The system may not operate at greatest efficiency.
b. There may be inaccurate ‘BioSafe’ sensing. For dangers refer to BioSafe Adjustment Value.
c. Hot water readings on the display may be misleading.
d. HWC Control may not work and HWC light may never operate or operate continually.

Warning:
These products are not designed for use in, and should not be used for patient connected applications. In
any critical installation an independent fail-safe back-up system must always be implemented.
