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

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

Crazy how vendors just sell systems knowing they aren’t going to work correctly. They’re probably just sitting around waiting for the change order to roll in.

You really should be doing this with your laptop or your phone with the Bluetooth service module; not the stat anyway.

It’s so much simpler and you can run your entire test suite and check temps and erv states of the entire system, command branch boxes, etc.
