SolaStat-Plus Mounting.
Where to mount the SolaStat-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 SolaStat-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 Sensors.
This is Critical to the Success of the Installation.
The sensors are the only way the SolaStat-Plus can efficiently control and protect the system.
1. The 10m ROOF Sensor. (Labelled ‘ROOF SENSOR’ - Solar Collector.)
The ‘ROOF’ sensor is best fitted into a metal immersion ‘pocket’ just inside the solar collectorin the
hot water outlet pipe. Liberally apply heat transfer compound between the sensor and the lining of the
‘pocket’. Sensor should be sealed with neutral cure sealant and externally lagged, also the cable
should be insulated from the bare pipe. Heat transfer compound is available from your distributor or
ICM ltd.
2. The 2m TANK Sensor. (Labelled ‘TANK SENSOR’ - HWC Upper.)
The ‘TANK’ sensor is best fitted into a metal immersion ‘pocket’ in the upper region of the HWC. For
the SolaStat-Plus-2 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. If Topout is required caution should be exercised to allow for stratification of hot water in the
tank. For Topout Adjustable Value we recommend a conservative value somewhat lower than the hot
water tank manufacturers maximum temperature. 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.
3. The 2m INLET Sensor. (Labelled ‘INLET SENSOR’ - HWC Lower.)
The ‘INLET’ sensor is mounted as per the ‘TANK’ sensor only this time it is mounted near the bottom
of the hot water tank.
Warning.
1. Removing or cutting the cladding may void hot water tank warranty.
2. Sensors must not be immersed in water.
3. It is recommended that sensor leads be kept 300mm away from mains and comms cables.
4. Ensure the correct sensors are mounted in the correct place.
5. Failure to properly mount the ‘Tank’ and ‘Inlet’ sensors as prescribed above can result in;
a. The system may not operate at greatest efficiency.
b. There may be inaccurate ‘Topout’ sensing. HWC or other components may get damaged.
c. There may be inaccurate ‘BioSafe’ sensing. For dangers refer to BioSafe Adjustment Value.
d. Hot water readings on the display may be misleading.
6. Failure to correctly mount the ‘Roof’ sensor as prescribed above can result in;
a. The s ystem may not operate at greatest efficiency.
b. Failure to detect Frost conditions. Panel can burst.
c. Hot water readings on the display may be misleading.
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.
