Frequently asked questions
What communication resistor value is required for the H770?
The power circuit must include a communication resistor of 200 to 500 Ω.
How can I change the variables shown on the LCD screen?
Press the S key to cycle through the variables (current, percentage, main variable, temperature) and release the key when the desired variable appears.
What does fault alarm E30 indicate?
Alarm E30 means the first float was not detected (no signal).
