The crank case heaters are specific to each compressor, they are turned on and off based on conditions for each compressor. Switching them could cause damage.
@@tcphvacr9950 I also rather keep connections as they are set in the factory... but what you mention must be model-specific. The Daikin VRVs I've serviced all have crankcase heaters on full-time. As a matter of fact, the manual states that turning on the equipment in cold weather requires pulling up the mains six hours earlier to ensure all compressors' oil is on temperature.
@@tcphvacr9950 I guess we can follow the tracks in one A1P and see if they are switched by independent mini-relays, or if they are both turned on by the same one.
DINURANGA KARUNATHILAKA I believe you should contact Daikin support for that, because once you reset you will have to recommission the system all over again. You should be able to check what you’ve done by reading the service manual and going through specific checks outlined in it.
If it is a two module system, you can't do it. If it is a single module system with one inverter and one standard, hold the BS1 button for 5 seconds until H1P becomes solid, press BS2 39 times, press BS3 once, and H7P flashes, press BS2 once and H6P flashes, press BS3 once and H6P becomes solid, and then press BS3 again to activate the setting.
Tito Diaz I don’t take calls to help, nor do I charge fees. I will however read messages and if I can, give help when I know the answer. I don’t mind sharing the knowledge, but don’t have the time to field calls. Send me a message via TH-cam and I’ll let you know if I can help.
If the A1P has been replaced, the dip switches aren’t set correctly. There should have been paperwork with the board showing your model and setting positions. Make sure you don’t have your “on” and “off” backwards.
If I remember correctly, the identical red ones are for the compressor's crankcase heating elements. They are interchangeable.

Thank you sir, but it's triple module vrv3. In this case what can I do? That means 3unit, 6inverter, 6 normal.
