IMPORTANT INFORMATION:

Terminals 45/46. A manual switch ON/OFF-I can be connected to these two terminals. 
By switching on the manual switch the filter pump is switched on and operation via 
the overflow channel is initiated. It is advisable to mount this manual switch near the 
pool.
Terminals 52/53. These terminals can be used in conjunction with an air-conditioning 
unit. When the contacts are closed, circulation is via the main drain.

Terminals 71/72:

 These terminals can be connected with the swimming pool cover.  

If these contacts are closed the ECO control (if set to AUTO) decides whether water 
will be circulated via the main drain or the overflow buffer tank. The pre-set filter times 
remain. The potential-free contact of the limit switch for the pool cover must be wired 
as follows: pool cover on the pool = closed limit switch contact.
.

Priorities

The overflow filter time always has priority over other actions. This means  
that when the unit is operating via the main drain (in economy mode) and the 
overflow filter times are active, the controls switch to normal operation. 
With the same objectives, the following priorities are active:
Im gleichen Sinn sind folgende Prioritäten vergeben: 

> 1. Overflow filter time
> 2. Manual switch (terminals 45/46)
> 3. Unit switch (auto/ main drain/ overflow tank)
> 4. Cover limit switch (terminals 71/72)
> 5. Eco-programme (set temperature and differential temperature)

FROST MONITOR

The frost protection mode only allows the heating to start, if the filter pump started 
over the air temperature.

Hysteresis

Example:
Set temperature 28 °C / hysteresis 1 °C / actual temperature 20 °C
In this example the heating will heat until 28 °C and then switch off. The heating will 
only switch on again when the water temperature drops below 27 °C. In this way you 
ensure that the temperature can only vary between 27 °C and 28 °C.
