The control unit was designed to suite a large variety of applications. All on / off times of the particular outputs are programmable for daytime or nighttime.
Daytime and nighttime can be specified .
Two different programs can be toggled by digital input 1 - e.g. Eco-program can be activated by manual switch.
Outputs used for valves can control blower output.
Special biology-build up function ensures proper bacteria growth within the first months of operation.
Outputs can be controlled by digital inputs / float switches.
Even customer specific features that are not yet implemented can be added on request. These are for example a sequential switching of two outputs with a certain time delay or a coupling of outputs.
The Sequetrol® easy unit is equipped with a preinstalled menu which was developed focusing on easy and intuitional operation. These points are part of the menu:
- Indication of operating hours.
- Manual control of the particular air / electric outputs.
- Indication of electric current / pressure (option).
- Modification of step times.
- Status of in- & outputs.
The service menu with its system-related settings is password protected.
Three buttons, three LEDs, an alphanumeric LCD display - regarding its operability our Sequetrol® easy leaves nothing to be desired. The device can be equipped with pressure and current sensing to monitor the compressor.
The Sequetrol® easy is also equipped with features, such as acoustic signaling of predefined conditions, a sequence program permanently saved in the EEPROM and a set of NiMH rechargeable batteries to ensure continuous signaling during power outage.
All electrical connections are implemented according to customer request - connectors or cost-effective and universally compatible screw type terminals .
