Minimax NT TSI heater

davsizApril 11, 2011

I have a MiniMax NT TSI gas heater, HTR-400-NT-STD-PH. It was installed August 2005. On the DDTC, only the power and pressure sw led's work. The SPA light is also lit up. Everything else is blank and not responding to inputs. I reset the circuit breaker. No luck. Any other ideas or suggestions for trouble shooting? Am I in need if a new DDTC?

Thanks.

chances are, yes. Especially if there is nothing coming out on the LED display.

The current temperature will display. However, nothing changes regardless of which buttons are pressed. Is there anything else that could cause this sort of problem other that the DDTC?

Sounds like a ddtc issue to me.
