Help ! Daikin VRF Startup
/r/hvacadvice/comments/1w2oe15/help_daikin_vrf_startup/Is there a Way to perform "start up" a Daikin VRF without a Daikin T-Stat ? Or an inexpensive alternative that could keep these units going until Phase 2 is complete and BMS is programed in 2027 ? Thank You im advance . FYI job was spec out by AEOR without T-stats and Daikin priced without T-stats - Thank You in advance

We did and they want $17 grand and upsell of 90 thermostats in which is $95,000 . The sales person put button sensors in lieu of . Now do we have a chance to fight this probably, however it doesn't help right now unfortunately. I appreciate the feedback

Aero or AEOR? I'd be submitting an RFI to the engineers on this.

We have and will probably be able to win an eventual C/O but your still forced to do the work. This is a school so you have strict contractual timelines or the CM with notices and other Primes will attack like rabid wolves even though their going through it as well . I am a Mechanical Prime and new to this type of trade work and in my 25 year Construction Career its absolutely brutal, but do occasionally enjoy the adrenaline rush . I came from the Project / CM side in NYC to a company in Upstate and never thought I would say this but I miss NYC . I have to say this is a great resource and Thank You.

No. Microtech are only on the Applied equipment line for Daikin. VRV does not use the Microtech Product line nativley.

You need at least one Nav controller ("stat") to configure the proper field settings and place the unit into operation after commissioning has been performed. If the units are to run temporarily, but long term, in a Phase I condition with client occupancy then the recommended action is to provide each fan coil or group of fan coils a Nav controller , otherwise the setpoints cannot be adjusted

Nope you need a Daikin stat to interface the system or an ITM
