The Altek SR658 controller is designed to control a solar heliosystem. The graphic digital display shows the selected control scheme and its parameters. Depending on the temperature at various points in the system, the controller issues commands to the system's actuators.

General characteristics:

LED large screen

6 relay outputs

1 low-voltage relay output for switching the boiler on/off

8 sensor inputs

1 input for a direct Grundfos TM (VFS) sensor

1 input for an electronic flow meter (FRT)

PWM outputs with variable frequency for controlling the speed of a high-efficiency pump

Data on Micro SD card

485 port for connecting a communication module

19 systems to choose from

Inputs:

2 PT1000 temperature sensors;

6 NTC10K temperature sensors, B=3950;

1 Grundfos sensor (VFS type);

1 electronic flow meter (FRT).

Outputs:

3 electromagnetic relays (maximum current 1A);

3 semiconductor relays (maximum current 1A);

1 low-voltage relay (on/off), boiler on/off;

PWM variable-frequency output (0-10V).

Functions:

Operating time counter, tubular collector function, thermostat function, pump speed control, heat quantity measurement, external heat exchanger, swimming pool system, customizable system parameters and additional functions (via menu), balancing and diagnostics.
