Re: Daikin muliti unit
Are there any fault codes showing or in the unit history?
If the unit is not running how do you know that the gas pressure is fine?Brian - Newton Abbot, Devon, UK

Re: Daikin muliti unit
As the outdoor unit can only heat or cool, but not at the same time, the indoor units must also be in the same mode to operate. If 1 of the indoor units is in a different mode, the green operation lamp will flash to tell you it is in standby mode when you switch it on.
If this is not happening, then you need to look at the pcb to determine if it has power and the HP1 LED is flashing
