4 Functions

4.1 Solar yield

The solar controller works on the principle of differen-

tial temperature control system. The controller always

switches on the collector pump when the difference in

temperature (collector temperature - cylinder tempera-

ture) is greater than the programmed activation differ-

ence.

The controller switches off the collector pump when the

difference in temperature (collector temperature - cylin-

der temperature) is less than the programmed deactiva-

tion difference.

The expert technician sets the parameters to the install-

er level when the solar controller is installed.

The solar yield is determined from:

– The difference in temperature between the collector‘s

forward flow and return flow

– The flow value specified (during installation) at the

control valve of the flow rate limiter

– The running time of the collector pump

During installation the expert technician sets the flow

rate limiter and enters the flow rate into the solar con-

troller at the installer level. The solar yield is calculated

by the solar controller. The total yield can be called up

and reset in the installer level.

4.2 Reheating

The reheating function allows the cylinder to heat up to

the required temperature during a set time window,

even if the solar yield is insufficient. In this case the

water can be reheated using an external heater or an

electrical heating rod. You can set up time windows for

reheating the solar cylinder (see Section 5.5.3 for de-

tails).

4.3 Reheating delay

The controller is equipped with a reheating delay func-

tion to prevent unnecessary reheating by an external

heater or an electrical heating rod. This function delays

reheating by up to 30 min. in case the collector pump is

running and the solar yield becomes available. If the col-

lector pump remains off and/or the desired cylinder

temperature is not reached after the delay period, the

cylinder is reheated using the external heater or electri-

cal heating rod.

The reheating delay function is activated in the installer

level.

4.4 Anti-legionella function

The anti-Legionnaire‘s disease protection function is de-

signed to kill germs in the cylinder and pipelines.

When the function is activated, the cylinder, the corre-

sponding hot water pipes and circulation pump (if in-

stalled) are brought to a temperature of at least 60 °C

once a week at a specific time on a specific day, or

every day.

In doing so, the cylinder temperature is raised to 71 °C

and the corresponding circulation pump is switched on

(if installed). The anti-legionella function is implemented

either via an external heater or electrical heating rod if

this is used for reheating. The anti-Legionnaire’s disease

protection function will stop once a temperature of at

least 68 °C has been maintained for a period of

30 minutes.

The anti-legionella function is activated by the expert

technician at installer level.

4.5 Pump blocking protection

If no pumping has occurred for 23 hours, all installed

pumps are switched on for roughly 3 seconds to prevent

the pumps from seizing.

4.6 Circulation

If you only have one collector field connected, a circula-

tion pump can be connected to the controller. You can

specify up to three heating windows for the circulation

pump in the timer program (see Sec. 5.5.4). Set up the

time program so that the circulation pump only oper-

ates at times when you expect a supply of hot water de-

mand will be needed. Otherwise the circulation pump

operates unnecessarily and inadvertently cools down

the cylinder.

4.7 Calendar

The controller is equipped with a calendar so that it can

automatically adjust for daylight-savings time. To acti-

vate it, simply enter the current date in the installer

level.

Note

Please observe that in the event of a power

failure the controller only has a power reserve

of 30 minutes. After 30 minutes, the internal

clock stops and the calender will not automati-

cally resume function once power has been re-

stored. In this case the time and date will need

to be reset.

4.8 Activation duration controlling

Activation duration controlling serves to keep the solar

circuit at the activation value, and thus in operation, for

as long as possible. The pump is switched on and off in

periodical bursts depending on the difference between

the collector temperature and lower cylinder sensor.

When the activation difference is reached, the function

is started (if activated) with an activation duration of

30 % – i.e. the pump is switched on for 18 seconds and

then switched off for 42 seconds. If the difference in

temperature increases, the activation duration is pro-

longed (e.g. 45 seconds on, 15 seconds off). If the differ-

ence in temperature falls, the activation duration is re-

duced (e.g. 20 seconds on, 40 seconds off). The period

length is always a minute. Activation duration control is

activated in the installer level.
