7 Functions and options
Switch-on difference
Adjustments/DTon
Adjustment range: 0.2 … 25.0 K
Factory setting: 2.5 K
Adjustment of the switch-on difference (TAbsorber - TPool) for the solar circuit
in Kelvin.
Switch-off difference
Adjustments/DToff
Adjustment range: 0.0 … 24.8 K

Maximum pool temperature
Adjustments/poolmax.
Adjustment range: 10 … 40 °C
Factory setting: 28 °C
Adjustment of the maximum pool temperature in °C.
When the adjusted maximum pool temperature is reached, the solar system
switches off. The circulation function is not inhibited.
Switch-on delay
Adjustments/t-DTon
Adjustment range: 00:01 … 10:00
Factory setting: 01:00
Adjustment of the switch-on delay t-DTon . The switch-on conditions must be fulfilled for this period of time for the solar loading to start.
Î First adjust the minutes and confirm the adjustment.
Î Then adjust the seconds and confirm the adjustment.
Minimum runtime
Adjustments/Min on
Adjustment range: 0 … 10 min
Factory setting: 2 min
Adjustment of the minimum runtime in minutes.
The minimum time for which the solar system remains switched on after the
switch-on conditions have been fulfilled. The minimum runtime is not aborted by
the maximum pool temperature limitation.
Minimum break time
Adjustments/Min off
Adjustment range: 0 … 10 min
Factory setting: 2 min
Adjustment of the minimum break time in minutes.
The period of time for which the solar system remains switched off after the
switch-off condition has been fulfilled.
Time
Adjustments/time
Adjustment of the current time
Minimum filter runtime
Adjustments/minimum filter runtime
Selection: “Yes”, “No”
Factory setting: “No”
Adjustments/filtration period
Adjustment range: 0 … 16 h
Factory setting: 5 h
Adjustments/ending time
Adjustment range: 00:00 … 23:30
Factory setting: 20:00
Adjustment of the minimum filter pump runtime in hours.
The filter pump is switched on for this adjusted filtration period every day.
The filter runtime ends when the adjusted ending time is reached.
The minimum filter runtime will also be complied with in the case of a sensor
failure.
Example: With a filter runtime of 4 hours, the filter pump has to be continuously
active from 16:00 o‘clock on in order to reach the adjusted runtime
before the adjusted ending time at 20:00 o‘clock is reached.

Circulation function
en
Adjustments/circulation
Selection: “Yes”, “No”
Factory setting: “No”
If the solar system has not been active for the period of one hour, it will be switched
on for 1 … 10 minutes (Flushing the pipes with pool water in order to measure the
pool temperature during a system standstill).
Adjustments/Starting time
Adjustment range: 00:00 … 23:45
Factory setting: 07:00
Adjustments/stopping time
Adjustment range: 00:15 … 24:00

Factory setting: “No”
The absorber maximum limitation inhibits solar loading from the absorber if the
adjusted temperature threshold (TAbs.max.) is exceeded.
Adjustments/TAbs.max.
Adjustment range: 60 … 160 °C
Factory setting: 130 °C
Adjustments /DTAbs.max.
Adjustment range: 2 … 50 K
Factory setting: 10 K
Adjustable switch-on and switch-off hysteresis (DTAbs.max.) which prevents the
controller from switching on and off again because of very small temperature differences.
Absorber minimum limitation
Adjustments/Absorbermin.
Selection: “Yes”, “No”
Factory setting: “No”
This function ensures that a solar loading is only effected if a given absorber temperature is exceeded.
Adjustments/TAbs.Min.
Adjustment range: 10 … 90 °C
Factory setting: 10 °C
Adjustments/DTAbs.min.
Adjustment range: 0.3 … 10 K
Factory setting: 2.0 K
Adjustable switch-on and switch-off hysteresis (DTAbs.min.) which prevents the con-
troller from switching on and off again because of very small temperature differences.
12
Pool cooling function
Adjustments/poolcooling
Selection: “Yes”, “No”
Factory setting: “No”
Experte/Adjustments/DTcool
Adjustment range: 0.3 … 10.0 K
Factory setting: 2.0 K
If the maximum pool temperature is exceeded by a certain value (DTcool), this
function cools the pool by discharging heat through the absorber. This is only possible if the absorber is cooler than the pool by the adjusted temperature difference
DTcoolon.
Cooling is switched off when the value DTcooloff is reached or when Poolmax. is
underrun.
Experte/Adjustments/DTcoolon
Adjustment range: 0.3 … 10.0 K
Factory setting: 3.0 K
Experte/Adjustments/DTcooloff
Adjustment range: 0.2 … 10.0 K
Factory setting: 1.5 K
The adjustable minimum difference between switch-on and switch-off temperature
(hysteresis) prevents the controller from switching on and off again due to very
small temperature differences..
Heat quantity balancing
Adjustments/heat quantity
Selection:“Yes”, “No”
Factory setting: “No”
Adjustments/flow rate
Adjustment range: 0.1 … 500 l/min
Factory setting: 5 l/min
Heat quantity balancing is possible if a flowmeter is used.
The flow rate should be read from the window of the flow setter at 100 % pump
speed and must be adjusted as flow rate.
Note
For heat quantity balancing, S4 has to be used for measuring the return
temperature (see chap. 3).
Manual operation
Manual operation/Relay1 (2)
Selection: “Off ”, “On”, “Auto”
Factory setting: “Auto”
Each relay can be set into the Off / On / Auto mode. During normal operation, the
relay is set to Auto.

8 Error indication
A possible failure of the pool-, flow- or absorber sensor will be indicated on the
display. The solar system will be switched off or, if already off, remain inactive. In the
case of a failure of the outdoor temperature sensor, the system will not be switched
off or kept inactive.

AM1 Alarm module
The AM1 alarm module is designed to signal system failures. It is to be connected to
®
the VBus
of the controller and issues an optical signal via a red LED if a failure has
occurred. The AM1 also has a potential-free relay output, which can e. g. be connected to a building management system (BMS). Thus, a collective error message can be
issued in the case of a system failure.
10.4 Accessories
en
DL2 Datalogger
This additional module enables the acquisition and storage of large amounts of data
(such as measuring and balance values of the solar system) over a long period of time.
The DL2 can be confi gured and read-out with a standard internet browser via its
integrated web interface. For transmission of the data stored in the internal memory
of the DL2 to a PC, an SD card can be used.
The DL2 is appropriate for all controllers with RESOL VBus®. It can be connected
directly to a PC or router for remote access and thus enables comfortable system
monitoring for yield monitoring or for diagnostics of faults.
10.3 Interface adapters
VBus® / USB interface adapter
The new VBus
a personal computer. With its standard mini-USB port it enables a fast transmission
of system data via the VBus
®
/ USB interface adapter is the interface between the controller and
