PERATING INSTRUCTIONS
Configuring your system
In order to guarantee maximum energy savings combined with
maximum comfort, it is important to configure your system in a proper
way.
For this reason, it is strongly recommended to do the following:
Use of schedule timers
Check the orientation of your solar panel, and find out during
what time of the day the intensity of the sun on it is expected to
be strong and weak. For example, a solar panel oriented to the
east will receive strong intensity during the morning, weak
intensity during the afternoon.
Example
Your domestic hot water consumption pattern is from 7 a.m. to 9 a.m. in the morning and from 5 p.m. till 11 p.m. in the evening.
Since the solar panel is oriented towards the south-east, the radiation can be intensive on the solar panel from 8 a.m to 6 p.m.

Domestic water heating/
booster heating
If the domestic hot water tank has not been heated enough by the
sun during the day, or a lot of warm water was consumed the evening
before, the domestic hot water tank must be heated up during the
night time by the unit, so that in the morning domestic hot water is
available for consumption. For this reason, in the example above,
domestic water heating is enabled during the night, until consumption
of warm water is expected to start.
In the morning, the domestic water heating/booster heating is
disabled. In this way, the domestic hot water tank is not reheated
after or during consumption of warm water and the sun will get the
chance to reheat the water as much as possible.
Since domestic hot water consumption is expected again from 5 p.m.
onwards, the domestic water heating and/or booster heating is
enabled again 1 hour before, from 4 p.m. onwards. This will
guarantee, in the case of absence of sun during the day, maximum
warm water capacity by 5 p.m.
NOTE
To set schedule timers, refer to the operation manual
of the unit.

Hour
Check your usual pattern of peak domestic hot water
consumption. E.g. showering during the morning from 7 to 9
a.m. and again in the evening from 5 p.m. onwards.
Set the schedule timer for 'domestic water heating' and 'booster
heating' as to disable heating of the domestic water tank by the
unit before solar radiation on the solar panel can become
intensive.
On the other hand, enable 'domestic water heating' and/or
'booster heating' about 1 hour before you usually expect
domestic hot water consumption or during night time. In this way,
the unit and/or booster heater will heat up the domestic water
tank and guarantee domestic hot water in the event there has
been no sun.

Setting of domestic hot water tank temperature
The domestic hot water tank has 2 temperature sensors.
The upper temperature sensor is the thermostat sensor of your unit.
This temperature can be set on your unit (refer to the operation
manual of the unit). It is advised to set this temperature as low as
possible. Start with a low temperature, e.g. 48°C. If with this
temperature you face shortage of warm water during normal tapping
patterns, increase gradually until you find the temperature of warm
water that covers your daily demand.
NOTE
Refer to the operation manual of the unit to change the
domestic hot water temperature setting.
The lower temperature sensor is the thermostat sensor of the solar
pump station. This temperature can be set on the solar pump station.
Put this temperature as high as possible but not higher than the listed
temperatures in function of domestic hot water tanks installed, as
otherwise the thermal protection in the tank might trip.
-
For EKHWS domestic hot water tank: 80°C
-
For EKHWSU domestic hot water tank: 70°C
-
For EKHWE domestic hot water tank: 75°C
NOTE
For optimal solar efficiency and system operation it is
advised that domestic hot water temperature setting
on the unit controller is lower than the temperature
setting on the solar pump station controller.
