Solar collector control

This solar collector control is perfect for controlling a normal solar collector system
monitors the temperature of the collector and the tank in two places,
starts the pump if necessary .
Electric auxiliary heating can also be switched on.

1 low-voltage relay output for switching the boiler on and off to turn it off
8 sensor inputs (input)
1 input for "Grundfos Direct Sensor TM"
1 input (FRT) for rotary knife electronic flow sensor
3 variable frequency PWM outputs for high efficiency pump
speed control
Data backup to TF card (Micro SD)
19 selectable systems

Product includes:
